Modbus
6 Modbus

1503 Modbus Mode (RTU/ASCII)
With Parameter
Modbus Mode
1503 the Modbus Communication Mode can be selected. The setting
applies to the slot of an optional communication module or to the X21-Connection (depending on the
setting of Parameter
Protocol (CM/X21)
395).
Modbus Mode
1503 Function
0- RTU Modbus via serial connection with RTU transfer mode.
1- ASCII Modbus via serial connection with ASCII transfer mode.
Attention!
Changes are effective immediately and without a restart of the frequency inverter.
The Modbus messages are described in Chapter 7.3.10 "Modbus Transmission Modes".

1504 Modbus Baud Rate
With Parameter
Modbus Baud Rate
1504 the transfer rate of the Modbus communication can be set.
The setting applies to the slot of an optional communication module or to the X21-Connection (de-
pending on the setting of Parameter
Protocol (CM/X21)
395).
Modbus Baud rate
1504 Function max. Line Length
1
1 – 2400 Baud Transfer rate 2400 Baud 30 m
2 – 4800 Baud Transfer rate 4800 Baud 30 m
3 – 9600 Baud Transfer rate 9600 Baud 30 m
4 – 19200 Baud Transfer rate 19200 Baud 30 m
5 – 57600 Baud Transfer rate 57600 Baud 10 m
6 – 115200 Baud Transfer rate 115200 Baud 10 m
7 – 230400 Baud Transfer rate 230400 Baud 10 m
Caution!
Changes are effective immediately and without a restart of the frequency inverter.
All bus participants must be set to the same baud rate.

1375 Modbus Parity
With Parameter
Modbus Parity
1375 the parity of the Modbus communication can be set. The setting
applies to the slot for an optional Communication Module or to the X21-Connection (depending on the
setting of Parameter
Protocol (CM/X21)
395).
Modbus Parity
1375 Function
0 – Even Even parity is used in the data transfer.
1 – Odd Odd parity is used in the data transfer.
2 – None No parity is used in the data transfer.
Attention!
Changes are effective immediately and without a restart of the frequency inverter.
1
The listed line lengths are recommended maximum values, which amongst other things, are dependent on the
properties of the cable.
The node address can be set with Parameter
Modbus Address
1376. Up to 247 frequency inverters
can be operated with Modbus. These are allocated a unique address in the range 1 to 247. The set-
ting applies to the slot of an optional Communication Module or to the X21-Connection (depending on
the setting of parameter
Protocol (CM/X21)
395).
Parameter Setting
Nr. Description Min. Max. Factory Setting
1376 Modbus Address 1 247 1
In most cases a change of the factory setting is not necessary (address 1).
Attention!
Changes are effective immediately and without a restart of the frequency inverter.
An address must be allocated for each participant.
Double assignments are not permitted when allocating bus addresses.
For details on addressing, see Chapter 7.1 "Address Representation".

1505 Modbus Watchdog Timer
The communication can be monitored. If the communication fails, then no data or incorrect data will
be transferred. This state will be detected by the Communication Watchdog.
The Watchdog-Function monitors the time, within which no correct communication occurs. This time
can be set with Parameter
Modbus Watchdog Timer
1505. The set value is the time in seconds with-
in which at least one correct data exchange must occur.
If the set monitoring time is reached the frequency inverter generates an error.
The setting applies to the slot of an optional Communication Module or to the X21-Connection (de-
pending on the setting of Parameter
Protocol (CM/X21)
395).
Parameter Setting
Nr. Description Min. Max. Factory Setting
1505 Modbus Watchdog Timer 0 s 10000 s 0 s
If the parameter is set to zero (factory setting), then monitoring is switched off.
