8.7.1 Fault 1 Output stage monitoring
Subfault: 1.1
Description: Short circuit in motor output terminals
Response: Output stage inhibit
Cause Measure
Overcurrent in output stage or faulty output stage
control detected, and output stage inhibited by
hardware. Possible causes for overcurrent are short circuit
at the output, excessive motor current, or a de-
fective power output stage.
Subfault: 1.2
Description: Overcurrent in output stage
Response: Output stage inhibit
Cause Measure
Motor current too high. Connect a smaller motor.
Current supply. Check the current supply.
Current transformer. Check the current transformer.
Ramp limit deactivated and set ramp time too
short. Increase the ramp time.
Phase module defective. Check the phase module.
DC 24 V supply voltage unstable. Check the DC 24 V supply voltage.
Interruption or short circuit on signal lines of
phase modules. Check the signal lines.
8.7.2 Fault 3 Ground fault
Subfault: 3.1
Description: Ground fault
Response: Output stage inhibit
Cause Measure
Ground fault in the motor lead. Eliminate ground fault in motor lead.
Ground fault in the inverter. Eliminate ground fault in inverter.
Ground fault in the motor. Eliminate ground fault in motor.
Ground fault in line components. Eliminate ground fault in line components.
