Safety Integrated Functions
8.5 Safety Integrated Extended Functions
Functional features of "Safe Operating Stop"
● The drive remains in the closed-loop control mode.
● A programmable standstill tolerance window is available.
● STOP B is the stop response after the standstill tolerance window has been violated
Note
The size of the tolerance window should be slightly above the standard standstill
monitoring limit, otherwise the standard monitoring functions will no longer be effective.
Parameter r9731 displays the safe position accuracy (load side) that can be achieved as
a maximum, based on the acquisition of the actual value for the safe motion monitoring
functions.
Responses
Standstill tolerance violated in p9330/p9530:
● STOP B with subsequent STOP A
● Safety message C01707/C30707
System errors:
● STOP F
● Safety message C01711/C30711
