P11.4 - SA bus (*DM1 Pro).
P11.4.1
a
SA bus device address
ID 1726
Minimum value:
204
Maximum value:
254
Default value:
204
Description:
This parameter is used to set the SA bus address at which the drive will be located on instance node.
P11.4. 2
a
SA bus baud rate
ID 1727
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
2
Options:
0 = 9,600;
1 = 19,200;
2 = 38,000;
3 = 57,600; or
4 = 115,200.
Description:
This parameter defines communication speed for SA bus communication.
P11.4.4
SA communication timeout
ID 1730
Minimum value:
0
Maximum value:
60,000
Default value:
10,000
Description:
Selects the time to wait before a communication fault occurs over SA bus if a message is not received.
P11.4. 5
SA bus protocol status
ID 1731
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
N.A.
Options:
0 = Stopped;
1 = Operational; or
2 = Faulted.
Description:
This parameter shows the protocol status for SA bus communication.
P11.4.6
SA bus fault response
ID 1732
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 SA bus communication.
P11.5 - SWD (*DM1 Pro).
P11.5.1
Parameter access
ID 2630
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
1
Options:
0 = No permission to read/write on acyclic channel.
1 = Acyclic read/write are allowed on Profibus.
Description:
PNU927 which specifies the operation priority of parameters for acyclic communication.
P11.5.2
a
Parameter data access
ID 2631
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
4
Options:
0 = Local control;
1 = Fieldbus;
2 = Mixed interface;
4 = NET, local on fault; or
5 = Dual mode.
Description:
PNU928 which specifies the control priority of the device for cyclic communication.

Fault situation counter
ID 2632
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
N.A.
Description:
PNU952 which specifies the fault situation counter.
Only write of 0 is allowed, then the whole fault buffer (actual fault situation and all other fault situations) and the fault message counter
(parameter 944) are erased.
