Converter with control units CU250D-2
344
Operating Instructions, 04/2015, FW V4.7.3, A5E34261542B AB
Number Cause
Remedy
A31418
Speed difference per sampling rate
exceeded
p0492 over several sampling cycles.
•
Check tachometer feeder cable for interruptions.
•
Check the grounding of the tachometer shielding.
•
Increase the maximum speed difference per sampling cycle (p0492).
F31905
Parameterizing error
Check whether the connected encoder type matches the encoder that
has been parameterized.
A31915
Configuration error
When the fine resolution Gx_XIST2 is configured, the encoder identifies a
maximum possible absolute position actual value (r0483) that can no
longer be represented within 32 bits. Remedy: Check the encoder data.
F32110
Serial communications error
The transfer of the serial communication protocol between the encoder
and converter is faulty. Remedy: Check the hardware and the associated
settings in the converter.
F32111
F32112
Absolute encoder internal error
•
Check the power supply of the encoder.
•
Replace the encoder.
A32410
Serial communication
•
Check that the encoder cables are routed in compliance with EMC.
•
Check the cable connections.
•
Replace the encoder.
A32411
Absolute encoder outputs alarms
Replace the encoder.
A32412
Error bit set in the serial protocol
•
Carry out a power on reset (power off/on) for all components.
•
Check that the encoder cables are routed in compliance with EMC.
•
Check the plug connections.
•
Replace the encoder
A32442
Battery voltage pre-alarm
Replace the battery in the encoder.
F32905
Parameterizing error
•
Check whether the connected encoder type matches the encoder that
has been parameterized.
•
Correct the parameter specified by the fault value (r0949) and p0187.
A32915
Configuration error
When the fine resolution Gx_XIST2 is configured, the encoder identifies a
maximum possible absolute position actual value (r0483) that can no
longer be represented within 32 bits. Remedy: Check the encoder data.
