6.13.2.4 Switch-off behavior in the event of a fault
The behavior of the drive always depends on the fault type and the setting of a number of dif-
ferent parameters (DRV.DISMODE, VBUS.UVFTHRESH, CS.VTHRESH, and others; see
the
AKD-N User Guide
or WorkBench help for more details).See the
Drive Fault and Warning
Messages and Remedies
section of the
AKD-N User Guide
for a table describing the spe-
cific behavior of each fault. The follwing pages show examples for the possible fault beha-
viors.
Switch-off behavior for faults that cause an immediate power stage disable
This is a category 0 stop according to IEC 60204.
If velocity drops below threshold
CS.VTHRESH
or timeout occurs the motor holding brake is
applied. Set parameter MOTOR.BRAKEIMM to 1 with vertical axes, to apply the motor hold-
ing brake immediately after faults.
