44 Parameter settings
Drive

Parameter 31.22 STO indication run/stop
The parameter setting in ACS880 primary control program:
•
parameter 31.22 STO indication run/stop is set to value Warning/Warning .
We recommend that you do not set parameter 31.22 STO indication run/stop to value 0 , 1
or 2 . This prevents the drive from making a fault every time the FSO module activates the
STO function.

Safety pulse encoder parameters
The drive parameter settings in ACS880 primary control program when you use a safety
pulse encoder:
•
parameter 90.41 Motor feedback selection is set to value Encoder 1 .
•
parameter 90.45 Motor feedback fault is set to value Warning .
Note : If you want that the drive trips on encoder faults, set this parameter to value
Fault . For more information, see the firmware manual.
•
parameter 92.21 Encoder cable fault mode is set to value A, B, Z .

SS1 ramp parameters
You must set these parameters only for the Emergency stop, stop category 1 option.
If FSO parameter 200.112 SAR1 ramp time to zero is set to 0 , drive parameters define the
stop ramp that is used in the SS1 function (stop category 1). Set:
•
21.04 Emergency stop mode to value Eme ramp stop (Off3)
•
23.23 Emergency stop time to a suitable value.
Also in this case, the FSO module monitors the actual stop ramp (ramp monitoring or time
monitoring).
For more information, see the firmware manual of your drive.
