Warning
!
With a vertical axis or pulling load, there is a risk of uncontrolled axis movements
when STOP A/F is initiated. This can be prevented by using safe brake control
(SBC) and a brake with sufficient holding force (not safety relevant).
For mechanically coupled axes, there is a risk of uncontrolled motion if a STOP
A/F is not initiated for all axes of the group.
Acknowledging the Safety faults
Faults associated with Safety Integrated Basic Functions must be acknowledged
as follows:
1. Remove the cause of the fault.
2. Select/deselect Safe Torque Off (STO).
3. Acknowledge fault.
If the safety commissioning mode is exited when the safety functions are swit-
ched off (p0010 = value not equal to 95 when p9601 = p9801 = 0), all the safety
faults can be acknowledged.
Once safety commissioning mode has been selected again (p0010 = 95), all the
faults that were previously present reappear.
Note
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.
