Safety data

Safety data values

￭
This safety data is valid for the default design of the safety circuit described in this manual.
If the final design is different from the default, ABB calculates new safety data and delivers
it separately to the customer.
The safety data calculations are based on the assumption that the emergency stop is used
once a month.
The safety pulse encoder is not included in the calculations, because it is not included in
the delivery. Only the FSE module is included in the calculations (if used).

ACS880-07/07LC/17/17LC/37/37LC drives without the FSE-31 module
