9.3.2.4 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 different parameters
(AXIS#.DISMODE, VBUS.UVFTHRESH, AXIS#.ZEROV, and others; see the WorkBench Online Help for more
details). See the Drive Fault and Warning Messages and Remedies section of the WorkBench User Manual for a
table describing the specific behavior of each fault. The next pages show examples for the possible fault behaviors.
The fault relay output (DOUT9) switches the main contactor (Emergency Off circuit).
Switch-off behavior for faults that cause an immediate power stage disable
This is a category 0 stop according to IEC 60204 (➜ # 20).
If the drive detects the motor to be at zero velocity (AXIS#.ZEROV) or timeout occurs (AXIS#.ZEROT), the motor
brake is applied (➜ # 101). Set parameter AXIS#.MOTOR. BRAKEIMM to 1 with vertical axes, to apply the motor
holding brake immediately after faults.
