Triggering Level Response Counter
The hardware short-circuit switch-off is active. The
output current is too high. If there is no supply
voltage when starting the device, the cause may
be a device-internal short circuit/ground fault.
Fault 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.
The brake chopper cuts out.

Possible cause Test Measure Confirmable
Interwinding fault Check the motor. Replace the motor. Yes
Fault in motor cable Check the cable Replace the cable.
Connection fault Check the connection, e.g. whether V or W
is connected to PE at X20 U.
Correct the connection.
Device-internal short circuit/ground
fault
Check whether the fault only occurs when
enabling the inverter.
Please contact our Service department.
Triggering Level Response Counter
An internal test is performed when the controller
part power supply is switched on. An existing
short-circuit causes a malfunction. A requirement
for triggering this event is for the supply voltage to
already be present when starting the device.
Fault This fault only occurs with the power board switched off.
The power board remains switched off and the drive is
torque-free/force-free. If the air override is inactive, a
possibly existing brake will be controlled to close.
