Warning: Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains. Also make sure that other voltage inputs have been disconnected (linkage of DC intermediate circuit). Be aware that there may be high voltage on the DC link even when the LEDs are turned off. Before touching any potentially live parts of the frequency converter, wait at least 4 minutes for all sizes. Shorter time is allowed only if indicated on the nameplate for the specific unit.

Leakage Current The earth leakage current from the frequency converter exceeds 3.5 mA. According to IEC 61800-5-1 a reinforced Protective Earth connection must be ensured by means of a min. 10mm² Cu or an addtional PE wire - with the same cable cross section as the Mains wiring - must be terminated separately. Residual Current Device This product can cause a DC current in the protective conductor. Where a residual current device (RCD) is used for extra protection, only an RCD of Type B (time delayed) shall be used on the supply side of this product. See also Danfoss Application Note on RCD, MN. 90.GX.YY. Protective earthing of the frequency converter and the use of RCDs must always follow national and local regulations.

Motor overload protection is possible by setting Parameter 1-90 Motor thermal protection to the value ETR trip. For the North American market: ETR functions provide class 20 motor overload protection, in accordance with NEC.

Installation in high altitudes: For altitudes above 2 km, please contact Danfoss regarding PELV.

1.1.5 IT Mains IT Mains Installation on isolated mains source, i.e. IT mains. Max. supply voltage allowed when connected to mains: 440 V.

3.1.3 EMC-Correct Installation Following these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN 61800-3 First environment is required. If the installation is in EN 61800-3 Second environment, then it is acceptable to deviate from these guidelines. It is however not recommended.

Good engineering practice to ensure EMC-correct electrical installation:



Use only braided screened/armoured motor cables and control cables. The screen should provide a minimum coverage of 80%.The screen material must be metal, not limited to but typically copper, aluminium, steel or lead. There are no special requirements for the mains cable.



Installations using rigid metal conduits are not required to use screened cable, but the motor cable must be installed in conduit separate from the control and mains cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of flexible conduits varies a lot and information from the manufacturer must be obtained.

• •

Connect the screen/armour/conduit to earth at both ends for motor cables and control cables. Avoid terminating the screen/armour with twisted ends (pigtails). Such a termination increases the high frequency impedance of the screen, which reduces its effectiveness at high frequencies. Use low impedance cable clamps or glands instead.



Ensure good electrical contact between the de-coupling plate and the metal chassis of the frequency converter, see Instruction MI.02.BX.YY.



Avoid using unscreened/unarmoured motor or control cables inside cabinets housing the drive(s), where possible.

3.2 Mains Connection 3.2.1 Connecting to Mains Step 1: First mount earth cable.

Step 2: Mount wires in terminals L1/L, L2 and L3/N and tighten.

Illustration 3.1: Mounting of earth cable and mains wires.

3 Electrical Installation

For 3-phase connection, connect wires to all three terminals. For single-phase connection, connect wires to terminals L1/L and L3/N.

Illustration 3.2: Three-phase and single-phase wire connections.

3.3 Motor Connection 3.3.1 How to Connect the Motor See the chapter Specifications for correct dimensioning of motor cable cross-section and length.



Use a shielded/armored motor cable to comply with EMC emission specifications, and connect this cable to both the decoupling plate and the motor metal.



Keep motor cable as short as possible to reduce the noise level and leakage currents.

For further details on mounting of the decoupling plate, please see instruction MI.02.BX.YY.

All types of three-phased asynchronous standard motors can be connected to the frequency converter. Normally, small motors are star-connected (230/400 V, Δ/Y). Large motors are delta-connected (400/690 V, Δ/ Y). Refer to motor nameplate for correct connection and voltage.

Illustration 3.3: Star and delta connections. Step 1: First, mount the earth cable.

Step 2: Connect wires to terminals either in star or delta-connection. See motor nameplate for further information.

5 Modbus RTU

5 Modbus RTU 5.1 Modbus RTU Overview 5.1.1 Assumptions These operating instructions assume that the installed controller supports the interfaces in this document and that all the requirements stipulated in the controller, as well as the frequency converter, are strictly observed, along with all limitations therein.

5.1.2 What the User Should Already Know The Modbus RTU (Remote Terminal Unit) is designed to communicate with any controller that supports the interfaces defined in this document. It is assumed that the user has full knowledge of the capabilities and limitations of the controller.

5

5.1.3 Modbus RTU Overview Regardless of the type of physical communication networks, the Modbus RTU Overview describes the process a controller uses to request access to another device. This includes i.a. how it will respond to requests from another device, and how errors will be detected and reported. It also establishes a common format for the layout and contents of message fields. During communications over a Modbus RTU network, the protocol determines how each controller will learn its device address, recognise a message addressed to it, determine the kind of action to be taken, and extract any data or other information contained in the message. If a reply is required, the controller will construct the reply message and send it. Controllers communicate using a master-slave technique in which only one device (the master) can initiate transactions (called queries). The other devices (slaves) respond by supplying the requested data to the master, or by taking the action requested in the query. The master can address individual slaves, or can initiate a broadcast message to all slaves. Slaves return a message (called a response) to queries that are addressed to them individually. No responses are returned to broadcast queries from the master. The Modbus RTU protocol establishes the format for the master’s query by placing into it the device (or broadcast) address, a function code defining the requested action, any data to be sent, and an error-checking field. The slave’s response message is also constructed using Modbus protocol. It contains fields confirming the action taken, any data to be returned, and an error-checking field. If an error occurs in receipt of the message, or if the slave is unable to perform the requested action, the slave will construct an error message and send it in response, or a time-out will occur.

5.1.4 Frequency Converter with Modbus RTU The frequency converter communicates in Modbus RTU format over the built-in RS-485 interface. Modbus RTU provides access to the Control Word and Bus Reference of the frequency converter.

The Control Word allows the Modbus master to control several important functions of the frequency converter: •

Start



Stop of the frequency converter in various ways: Coast stop Quick stop DC Brake stop Normal (ramp) stop



Reset after a fault trip



Run at a variety of preset speeds



Run in reverse



Change the active set-up



Control the frequency converter’s built-in relay

The Bus Reference is commonly used for speed control. It is also possible to access the parameters, read their values, and where possible, write values to them. This permits a range of control options, including controlling the setpoint of the frequency converter when its internal PI controller is used.

5 Modbus RTU

5.2 Modbus RTU Message Framing Structure 5.2.1 Remote Terminal Unit The controllers are set up to communicate on the Modbus network using RTU (Remote Terminal Unit) mode, with each 8-bit byte in a message containing two 4-bit hexadecimal characters.

The format for each byte is shown below.

Start bit

5

Data bit

Stop/parity Stop

Coding system:

8-bit binary, hexadecimal 0-9, A-F. Two hexadecimal characters contained in each 8-bit field of the message.

Bits per byte:

1 start bit 8 data bits, least significant bit sent first Parity: 1 bit for even/odd parity is used; 1 or 2 stop bits if no parity is selected (see par. 8-33).

Error Check Field:

Cyclical Redundancy Check (CRC).

5.2.2 Modbus RTU Message Structure The transmitting device places a Modbus RTU message into a frame with a known beginning and ending point. This allows receiving devices to begin at the start of the message, read the address portion, determine which device is addressed (or all devices, if the message is broadcast), and to recognise when the message is completed. Partial messages are detected and errors set as a result - or timeouts occur. Characters for transmission must be in hexadecimal 00 to FF format in each field.

The frequency converter continuously monitors the network bus, also during “silent” intervals. When the first field (the address field) is received, each frequency converter or device decodes it to determine which device is being addressed. Modbus RTU messages addressed to zero are broadcast messages. No response is permitted for boradcast messages. A typical message frame is shown below.

N x 1 byte

2 bytes

T1-T2-T3-T4

Table 5.1: Typical Modbus RTU Message Structure

5.2.3 Start/Stop Field Messages start with a silent period of at least 3.5 character intervals. This is implemented as a multiple of character intervals at the selected network baud rate (shown as Start T1-T2-T3-T4). The first field to be transmitted is the device address. Following the last transmitted character, a similar period of at least 3.5 character intervals marks the end of the message. A new message can begin after this period.

The entire message frame must be transmitted as a continuous stream. If a silent period of more than 1.5 character intervals occurs before completion of the frame, the receiving device flushes the incomplete message and assumes that the next byte will be the address field of a new message. Similarly, if a new message begins prior to 3.5 character intervals after a previous message, the receiving device will ignore both messages. This will cause a timeout (no response from the slave).

VLT® Micro Drive FC 51 Operating Instructions

5 Modbus RTU

5.2.4 Address Field The address field of a message frame contains 1 byte. Valid slave device addresses are in the range of 0 - 247 decimal. The individual slave devices are assigned addresses in the range of 1 - 247 (0 is reserved for broadcast mode, which all slaves recognise). A master addresses a slave by placing the slave address in the address field of the message.

When the slave sends its response, it places its own address in this address field to let the master know which slave is responding.

5.2.5 Function Field The function field of a message frame contains 1 byte. Function fields are used to send messages between master and slave. When a message is sent from a master to a slave device, the function code field tells the slave what kind of action to perform. When the slave responds to the master, it uses the function code field to indicate either a normal (error-free) response, or that some kind of error occurred (called an exception response).

For a normal response, the slave simply echoes the original function code. For an exception response, the slave returns a code that is equivalent to the

5

original code with its most significant bit set to logic 1. In addition, the slave places a unique code into the data field of the response message. This tells the master what kind of error occurred, or the reason for the exception. Please also refer to the sections Function Codes Supported by Modbus RTU and

Exception Codes.

5.2.6 Data Field The data field is constructed using sets of two hexidecimal digits in the range of 00 to FF hexidecimal. These are made up of one RTU character. The data field of messages sent from a master to a slave device contains additional information which the slave must use to take the action defined by the function code. This can include items such as addresses of coils or registers, the quantity of items to be handled. and the count of actual data bytes in the field.

5.2.7 CRC Check Field Messages include an error-checking field, operating on the basis of a Cyclical Redundancy Check (CRC) method. The CRC field checks the content of the entire message. It is applied regardless of any parity check method used for the individual characters of the message.

The CRC value is calculated by the transmitting device, which appends the CRC as the last field in the message. The receiving device recalculates a CRC during receipt of the message and compares the calculated value to the actual value received in the CRC field. If the two values are unequal, a bus timeout occurs. The error-checking field contains a 16-bit binary value implemented as two 8-bit bytes. When this is done, the low-order byte of the field is appended first, followed by the high-order byte. The CRC high-order byte is the last byte sent in the message.

5.2.8 Coil/Register Addressing In Modbus, all data are organised in coils and holding registers. Coils hold a single bit, whereas holding registers hold a 2-byte word (i.e. 16 bits). All data addresses in Modbus messages are referenced to zero. The first occurrence of a data item is addressed as item number zero.

Example: The coil known as “coil 1” in programmable controller is addressed as coil 0000 in the data address field of a Modbus message. Coil 127 decimal is addressed as coil 007EHEX (126 decimal).

Holding register 40001 is addressed as register 0000 in the data address field of the message. The function code field already specifies a “holding register” operation. Therefore, the “4XXXX” reference is implicit. Holding register 40108 is addressed as register 006BHEX (107 decimal).

5.3.2 Exception and Error Codes In the event of an error, the following exception codes may appear in the data field of a response message. For a full explanation of the structure of an exception (i.e. error) response, please refer to Function Field in section Modbus RTU Message Framing Structure.

MODBUS Exception Codes Code Name 1

Illegal function

Meaning The function code received in the query is not an allowable action for the server (or slave). This may be because the function code is only applicable to newer devices, and was not implemented in the unit selected. It could also indicate that the server (or slave) is in the wrong state to process a request of this type, for example it is not configured and is being asked to return register values.

2

Illegal data address The data address received in the query is not an allowable address for the server (or slave). More specifically, the combination of reference number and transfer length is invalid. For a controller with 100 registers, a register with offset 96 and length 4 would succeed, a request with offset 96 and length 5 will generate exception 02.

3

Illegal data value

A value contained in the query data field is not an allowable value for server (or slave). This indicates a fault in the structure of the remainder of a complex request, such as an incorrect implied length. It specifically does NOT mean that a data item submitted for storage in a register has a value outside the expectation of the application program, since the MODBUS protocol is unaware of the significance of any particular value of any particular register.

4

Slave device failure An unrecoverable error occurred while the server (or slave) was attempting to perform the requested action

In case of an exception code 4 while accessing parameter values in the drive, detailed information about the latest exception can be read from the drives Holding Register 0007. This register may contain one of the following, detailed error codes regarding the latest occurring MODBUS Exception.

5.4 How to Access Parameters

5

5.4.1 Parameter Handling The PNU (Parameter Number) is translated from the register address contained in the Modbus read or write message. The parameter number is translated to Modbus register address as (10 x parameter number -1)DECIMAL.

5.4.2 Storage of Data The Coil 65 decimal determines whether data written to the frequency converter are stored in EEPROM and RAM (coil 65 = 1) or only in RAM (coil 65 = 0).

5.4.3 IND The array index is set in Holding Register 9 and used when accessing array parameters.

5.4.4 Text Blocks Parameters stored as text strings are accessed in the same way as the other parameters. The maximum text block size is 20 characters. If a read request for a parameters is for more characters than the parameter stores, the response is truncated. If the read request for a parameter is for fewer characters than the parameter stores, the response is space filled.

5.4.5 Conversion Factor The different attributes for each parameter can be seen in the section on factory settings. Since a parameter value can only be transferred as a whole number, a conversion factor must be used to transfer decimals. Please refer to the section Conversion Index.

5.4.6 Parameter Values Standard Data Type Standard data types are int16, int32, uint8, uint16 and uint32. They are stored as 4x registers (40001 - 4FFFF). The parameters are read using function 03HEX “Read Holding Registers”. Parameters are writtein using the function 6HEX “Preset Single Register” for 1 register (16 bits), and the function 10HEX “Preset Multiple Registers” for 2 registers (32 bits). Readable sizes range from 1 register (16 bits) up to 10 registers (20 characters). Non Standard Data Types Non standard data types are text strings and are stored as 4x registers (40001 - 4FFFF). The parameters are read using function 03HEX “Read Holding Registers” and written using function 10HEX “Preset Multiple Registers”. Readable sizes range from 1 register (2 characters) up to 10 registers (20 characters).

5.5 Examples The following examples illustrate various Modbus RTU commands. If an error occurs, please refer to the Exception Codes section.

VLT® Micro Drive FC 51 Operating Instructions

5 Modbus RTU Bit 03, Coasting: Bit 03 = “0” shuts off the output transistors causing the motor to coast to a standstill.

Bit 03 = “1” enables the frequency converter to start the motor if the other starting conditions have been fulfilled.

NB! In par. 8-50 Coasting select a selection is made to define how Bit 03 gates with the corresponding function on a digital input.

Bit 04, Quick stop: Bit 04 = “0” causes a stop, in which the motor speed is ramped down to stop via 9ar. 3-81 Quick stop ramp time.

Bit 05, Hold output frequency:

5

Bit 05 = “0” causes the present output frequency (in Hz) to freeze. The frozen output frequency can then be changed only by means of the digital inputs (par. 5-10 to 5-15) programmed to Speed up and Speed down.

NB! If Freeze output is active, the frequency converter can only be stopped by the following:



Bit 03 Coasting stop



Bit 02 DC braking



Digital input (par. 5-10 to 5-15) programmed to DC braking, Coasting stop or Reset and coasting stop.

Bit 06, Ramp stop/start: Bit 06 = “0” causes a stop, in which the motor speed is ramped down to stop via the selected ramp down parameter. Bit 06 = “1” permits the frequency converter to start the motor, if the other starting conditions have been fulfilled.

NB! In par. 8-53 Start select a selection is made to define how Bit 06 Ramp stop/start gates with the corresponding function on a digital input.

Bit 07, Reset: Bit 07 = “0” does not cause a reset. Bit 07 = “1” causes the reset of a trip. Reset is activated on the signal's leading edge, i.e. when changing from logic “0” to logic “1”.

Bit 08, Jog: Bit 08 = “1” causes the output frequency to be determined by par. 3-19 Jog speed.

Bit 09, Selection of ramp 1/2: Bit 09 = “0” means the ramp 1 is active (par. 3-40 to 3-47). Bit 09 = ”1” means that ramp 2 (par. 3-50 to 3-57) is active.

Bit 10, Data not valid/Data valid: Is used to tell the frequency converter whether the control word is to be used or ignored. Bit 10 = “0” causes the control word to be ignored. Bit 10 =”1” causes the control word to be used.

Bit 11, Relay 01: Bit 11 = “0” Relay 01 not activated Bit 11 = “1” Relay 01 is activated, provided Control word Bit 11 has been chosen in par. 5-40 Function relay.

VLT® Micro Drive FC 51 Operating Instructions

5 Modbus RTU 5.6.4 Explanation of the Status Bits Bit 00, Control not ready/ready: Bit 00 = “0” means that the frequency converter has tripped.

Bit 00 = “1” means that the frequency converter controls are ready, but that the power component is not necessarily receiving any power supply (in case of external 24 V supply to controls).

Bit 01, Frequency converter ready: Bit 01 = “1”. The frequency converter is ready for operation, but there is an active coasting command via the digital inputs or via serial communication.

Bit 02, Coasting stop: Bit 02 = “0”. The frequency converter released the motor. Bit 02 = “1”. The frequency converter can start the motor when a start command is given.

5

Bit 03, No error/trip: Bit 03 = “0” means that the frequency converter is not in fault mode. Bit 03 = “1” means that the frequency converter is tripped, and that a reset signal is required to re-establish operation.

Bit 04, No error/error (trip): Bit 04 = “0” means that the frequency converter is not in fault mode. Bit 04 = “1” means that there is a frequency converter error but no trip.

Bit 05: Not used.

Bit 06, No error/trip lock: Bit 06 = “0” means that the frequency converter is not in fault mode. Bit 06 = “1” means that the frequency converter is tripped and locked.

Bit 07, No warning/warning: Bit 07 = “0” means that there are no warnings. Bit 07 = “1” means that a warning has occurred. Bit 08, Speed ≠ reference/speed = reference: Bit 08 = “0” means that the motor is running, but that the present speed is different from the preset speed reference. For example, this might occur while the speed is being ramped up/down during start/stop. Bit 08 = “1” means that the present motor speed matches the preset speed reference.

Bit 09, Local operation/bus control: Bit 09 = “0” means that [Stop/Reset] is activated on the control unit. It is not possible to control the frequency converter via serial communication. Bit 09 = “1” means that it is possible to control the frequency converter via serial communication.

Bit 10, Out of frequency limit: Bit 10 = “0”, if the output frequency has reached the value in par. 4-12 Motor speed low limit or par . 4-13 Motor speed high limit. Bit 10 = “1” means that the output frequency is within the defined limits.

Bit 11, Running: Bit 11 = “0” means that the motor is not running. Bit 11 = “1” means that the frequency converter has a start signal or that the output frequency is higher than 0 Hz.

Bit 12, Resistor brake fault: Bit 12 = “0” means that there is no resistor brake fault. Bit 12 = “1” means that there is a resistor brake fault.

Bit 13, Voltage OK/limit exceeded: Bit 13 = “0” means that there are no voltage warnings. Bit 13 = “1” means that the DC voltage in the frequency converter's intermediate circuit is too low or too high.

Bit 14, Torque OK/limit exceeded: Bit 14 = “0” means that there are no current/torque warnings or errors. Bit 14 = “1” means that there is a current/torque warning or error.

Bit 15, Thermal warning: Bit 15 = “0” means that there is no thermal warning or error. Bit 15 = “1” means that one of the thermal limits has been exceeded.

5.6.5 Bus Speed Reference Value The speed reference value is transmitted to the frequency converter in a

5

relative value in %.

The value is transmitted in the form of a 16-bit word; in integers (0-32767) the value 16384 (4000 Hex) corresponds to 100%. Negative figures are formatted by means of 2's complement.

The Actual Output Frequency (MAV) is scaled in the same way as the bus reference.

The reference and MAV are scaled as follows:

6 Parameter Overview

6.2.1 Conversion Index The various attributes of each parameter are displayed in the section Factory Settings. Parameter values are transferred as whole numbers only. Conversion factors are therefore used to transfer decimals according to the table below.

Example: Par. 1-24 Motor Current has a conversion index of -2 (i.e. conversion factor of 0.01 according to the table below). To set the parameter to 2.25 A, transfer the value 225 via Modbus. The Conversion Factor of 0.01 means that the value transferred is multiplied by 0.01 in the drive. The vale 225 transferred on the bus is thus perceived as 2.25 A in the drive.

Table 6.1: Conversion table

6.2.2 Change during operation “TRUE” means that the parameter can be changed while the frequency converter is in operation and “FALSE” means that the frequency converter must be stopped before a change can be made.

6.2.3 2-Set-up “All set-up”: The parameter can be set individually in each of the two set-ups, i.e. one single parameter can have two different data values. ”1 set-up”: Data value will be the same in both set-ups.

Error

Cause of Problem Signal on terminal 53 or 60 is less than 50% of value set in par. 6-10, 6-12 and 6-22. Missing phase on supply side, or too high voltage imbalance. Check supply voltage. Intermediate circuit voltage exceeds limit. Intermediate circuit voltage drops below “voltage warning low” limit. More than 100% load for too long. Motor is too hot due to more than 100% load for too long. Thermistor or thermistor connection is disconnected. Torque exceeds value set in either par. 4-16 or 4-17. Inverter peak current limit is exceeded. Discharge from output phases to ground. Short-circuit in motor or on motor terminals. No communication to frequency converter. Brake resistor is short-circuited, thus brake function is disconnected. Brake transistor is short-circuited, thus brake function is disconnected. Brake resistor is not connected/working Heat-sink cut-out temperature has been reached. Motor phase U is missing. Check the phase. Motor phase V is missing. Check the phase. Motor phase W is missing. Check the phase. Contact local Danfoss supplier. 24 V DC may be overloaded. Wrong setting for motor voltage and/or motor current. Motor current is too low. Check settings. VLT overload. Actual motor current has not exceeded “release brake” current within “start delay” time window. All parameter settings are initialized to default settings. No communication between LCP and frequency converter See parameter group 0-4* LCP An error occurred while copying from frequency converter to LCP or vice versa. Occurs when copying from LCP if the LCP contains erroneous data - or if no data was uploaded to the LCP. Occurs when copying from LCP if data are moved between frequency converters with major differences in software versions. Occurs when trying to write to a read-only parameter. LCP and RS485 connection are trying to update parameters simultaneously. Occurs when trying to write an illegal value to a parameter. Occurs when trying to set a value outside the range. Parameter can only be changed when the motor is stopped. Occurs when using a wrong password for changing a password-protected parameter.

8.3 Special Conditions 8.3.1 The Purpose of Derating Derating must be taken into account when using the frequency converter at low air pressure (heights), at low speeds or at high ambient temperature. The required action is described in this section.

8.3.2 Derating for Ambient Temperature

8

The ambient temperature measured over 24 hours should be at least 5 °C lower than the max. ambient temperature.

If the frequency converter is operated at high ambient temperature, the continuous output current should be decreased.

The frequency converter has been designed for operation at max 50 °C ambient temperature with one motor size smaller than nominal. Continuous operation at full load at 50 °C ambient temperature will reduce the lifetime of the frequency converter.

8.3.3 Derating for Low Air Pressure The cooling capability of air is decreased at low air pressure.

For altitudes above 2000 m, please contact Danfoss regarding PELV.

Below 1000 m altitude no de-rating is necessary but above 1000 m the ambient temperature or the maximum output current should be decreased. Decrease the output by 1% per 100 m altitude above 1000 m or reduce the max. ambient temperature by 1 degree per 200 m

8.3.4 Derating for Running at Low Speeds When a motor is connected to at frequency converter, it is necessary to check that the cooling of the motor is adequate. A problem may occur at low speeds in constant torque applications. Running continuously at low speeds – below half the nominal motor speed – may require additional air cooling. Alternatively, choose a larger motor (one size up).
