ABB ACS880-07 - Safety pulse encoder parameters; SS1 ramp parameters

Safety pulse encoder parameters
The drive parameter settings in ACS880 primary control program when you use a 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):
•
21.04 Emergency stop mode is set to value Eme ramp stop (Off3)
•
23.23 Emergency stop time is set 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.
