Baud rate
ID 584
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
1
Options:
0 = 9,600;
1 = 19,200;
2 = 38,400;
3 = 57,600; or
4 = 115,200
Description:
This parameter defines communication speed for RS-485 communication.
P11.2.3
a
Parity type
ID 585
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
2
Options:
0 = None;
1 = Odd; or
2 = Even.
Description:
This parameter defines parity type for RS-485 communication.
P11.2.4
Modbus RTU protocol status
ID 588
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
N.A.
Options:
0 = Initial;
1 = Stopped;
2 = Operational; or
3 = Faulted.
Description:
This parameter shows the protocol status for RS-485 communication.
P11.2.5
Communication timeout modbus RTU
ID 593
Minimum value:
0.00 ms
Maximum value:
60,000.00 ms
Default value:
10,000.00 ms
Description:
Selects the time to wait before a communication fault occurs over modbus RTU if a message is not received.
P11.2.6
Modbus RTU fault response
ID 2516
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 - Only in fieldbus control mode. When fieldbus is the control place and fieldbus fault is active, the drive will fault on loss of
communications; if not in fieldbus control, place will not fault.
1 - In all control modes. No matter the control place setting, if communication is lost, fieldbus fault response will occur.
Description:
Defines the fieldbus fault condition for modbus RTU communication.
