Operating Instructions, 04/2017, A5E37208830-003
Cause
The drive unit did not accept the receive
configuration data.
There is no cyclic connection to the con-
trol.
A consistency error was detected when
activating the configuration.
Note: Currently set configuration has not
been activated.
The DC link voltage is too low.
Hardware current limit for phase U re-
sponded. The pulsing in this phase is in-
hibited for one pulse period.
Closed-loop control is incorrectly pa-
•
rameterized.
Fault in the motor or in the power ca-
•
bles.
The power cables exceed the maxi-
•
mum permissible length.
Motor load too high.
•
Power unit defective.
•
Note:
Alarm A30031 is always output if, for a
power unit, the hardware current limiting of
phase U, V or W responds.
The absolute encoder fault word includes
alarm bits that have been set.
12.1 List of faults and alarms
Remedy
Check the receive configuration data.
Establish the cyclic connection and acti-
•
vate the control with cyclic operation.
Check the parameters "Name of Station"
•
and "IP of Station" (r8930, r8931).
Check the required interface configuration,
correct if necessary.
Switch on the load supply.
•
Check the line supply if necessary.
•
Check the motor data. As an alternative, run
a motor data identification.
Check the motor circuit configuration
•
(star-delta)
Check the motor load.
•
Check the power cable connections.
•
Check the power cables for short-circuit or
•
ground fault.
Check the length of the power cables.
•
Check the encoder cable connection and
•
make sure the cables are routed in com-
pliance with EMC.
Check the motor temperature.
•
Replace the motor/encoder.
