Fault
Parameterized fault response in
A29
:
•
A29 = 0:inactive
The power board is switched off and the drive
becomes torque-free/force-free. If the air override is
inactive, a possibly existing brake will be controlled to
close.
•
A29 = 1:active
The drive is stopped with a quick stop. If the air
override is inactive, a possibly existing brake will be
controlled to close at the end of the quick stop.
If the event is triggered at a threshold of 100%, current
limiting is performed in the control modes with vector
control. Reducing the current can cause the fault quick
stop to no longer perform correctly.
