Safety Functions Integrated in the Drive
4.6 Commissioning the STO, SBC and SS1 functions
Acknowledging safety faults
Safety Integrated faults must be acknowledged as follows:
1. Remove the cause of the fault.
2. Select/deselect Safe Torque Off (STO).
3. Acknowledge the fault.
If the safety commissioning mode is exited when the safety functions are switched
off (p0010 = value not equal to 95 when p9601 = p9801 = 0), all the safety faults
can be acknowledged.
After the safety commissioning mode has been set again (p0010 = 95), all of the
faults that were previously available, re–appear.
Notice
Safety faults can also be acknowledged (as with all other faults) by switching the
drive unit off and then on again (power on).
If the fault cause has still not been resolved, then the fault is immediately
displayed again after booting.
