Remedy
Check the fan filter elements.
•
Check whether the ambient temperature is in the permissible range.
•
See F30035 and, in addition:
Check the motor load.
•
Check the line phases
•
Check the internal fan and if required replace.
Check the internal fan and if required replace.
Check the unit supply voltage (p0210).
•
Check the dimensioning of the line reactor.
•
Check that the sensor is connected correctly.
The measured zero mark distance does not correspond to the
parameterized zero mark distance. Remedy:
Check that the encoder cables are routed in compliance with EMC.
•
Check the cable connections.
•
Check the encoder type (encoder with equidistant zero marks).
•
Adapt the parameters for the distance between zero marks (p0424,
•
p0425).
For a signal output above a speed threshold, reduce the filter time
•
(p0438).
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).
•
Check whether the connected encoder type matches the encoder that
has been parameterized.
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.
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.
Check the power supply of the encoder.
•
Replace the encoder.
•
Check that the encoder cables are routed in compliance with EMC.
•
Check the cable connections.
•
Replace the encoder.
•
Replace the encoder.
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
