MB Idle [777]
Selecting how the inverter should react when it is not communicating with the
Modbus master.
After the defined idle time the warning occurs, or the fault. Or first the warning and
then the fault.
□ Fault
The inverter generates the fault " E42-Modbus Timeout (page 33)", when no valid request or
broadcast (if allowed) is received from the Modbus master within the preset time.
□ Warning
The inverter generates the warning " W41-Profibus Timeout (page 30)", when no valid
request or broadcast (if allowed) is received from the Modbus master within the preset time.
□ Fault CW
The inverter generates the fault " E42-Modbus Timeout (page 33)", when no control word or
setpoint is received in valid request or broadcast(if allowed) from the Modbus master within
the preset time.
□ Warning CW
The inverter generates the warning " W41-Profibus Timeout (page 30)", when no control
word or setpoint is received in valid request or broadcast(if allowed) from the Modbus master
within the preset time.

Fault
timeout [606]
Timeout of communication interruption with Master. After this time, fault E42-
Modbus Timeout (page 33) is generated.

MB Warning
timeout [833]
Timeout of communication interruption with Master. After this time, warning "
W41-Profibus Timeout (page 30)" is generated. If a Modbus protocol fault and
warning are evaluated at the same time, see MB Idle [777] (page 81), then this
parameter must be lower than the parameter MB Fault timeout [606] (page 81),
otherwise the warning will not be generated.

MB Warning
mode [834]
Defines what action should the inverter take after Modbus warning occurs.

Broadcast
[983]
Turning on / off the broadcasts. Broadcast is a message which is sent to all
recipients simultaneously.
Yes
Yes
Broadcasts are turned on and the inverter is processing them.
No
Broadcasts are turned off and the inverter is ignoring them.
DataFormat
[607]
This parameter defines the order of transferring single bytes. This change of
format is only applied for the 485 line. This is the parameter data, SW, CW, and
accelerated block transfer. By default, 32-bit data 0xHhHlLhLl is transmitted in the
order 0xHh, 0xHl, 0xLh, 0xLl.
No swap
No swap
32 bit data are transfered in the byte order: 0xHh, 0xHl, 0xLh, 0xLl.
Byte swap
32 bit data are transfered in the byte order: 0xHl, 0xHh, 0xLl, 0xLh.
Word swap
32 bit data are transfered in the byte order: 0xLh, 0xLl, 0xHh, 0xHl.
Byte & word
swap
32 bit data are transfered in the byte order: 0xLl, 0xLh, 0xHl, 0xHh.
