7.14.2.4 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 WorkBench Online Help for more details).See the Drive Fault and Warning Messages
and Remedies section of the WorkBench Online Helpfor a table describing the specific beha-
vior of each fault.
The follwing pages show examples for the possible fault behaviors.
Switch-off behavior for faults that cause an immediate power stage disable
This is a category 0 stop according to IEC 60204 (➜ # 53).
If velocity drops below threshold CS.VTHRESH or timeout occurs the motor holding brake is
applied (➜ # 118). Set parameter MOTOR.BRAKEIMM to 1 with vertical axes, to apply the
motor holding brake immediately after faults.
