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

is in EN 61800-3

Good engineering practice to ensure EMC-correct electrical installation:

Second environment

, then it is acceptable to deviate from these guidelines. It is however not recommended.

First environment

is required. If the 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.

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.

5.1.3. 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.

5.2. 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.

tions

5

Start bit

Coding system: 8-bit binary, hexadecimal 0-9, A-F. Two hexadecimal characters contained in each 8-bit field of

Bits per byte: 1 start bit

Error Check Field: Cyclical Redundancy Check (CRC).

Data bit Stop/pari-tyStop

the message.

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).

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.

Start

T1-T2-T3-T4 1 byte 1 byte N x 1 byte 2 bytes T1-T2-T3-T4

Address Function Data CRC check End

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 time-

out (no response from the slave).

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.

24

MG.02.A3.02 - VLTp is a registered Danfoss trademark

VLTp Micro Drive FC 51 Operating Instruc­tions

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

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

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

Function Codes Supported by Modbus RTU

5. Modbus RTU

and

5

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 time-

out 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 007E

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 006B

(126 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

Code Name Meaning

1 Illegal function 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

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

The speed reference value is transmitted to the frequency converter in a

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 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.

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.

Protection and Features:

• Electronic thermal motor protection against overload.

• Temperature monitoring of the heatsink ensures that the frequency converter trips in case of overtemperature

• The frequency converter is protected against short-circuits on motor terminals U, V, W.

• If a motor phase is missing, the frequency trips and issues an alarm.

• If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).

• Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit voltage is too low or too high.

• The frequency converter is protected against earth faults on motor terminals U, V, W.

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

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 VLT Micro Drive FC 51 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 Drives 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).
