1. Wiring of encoder cable is incorrect or defective. Pin assignment
(encoder signals) in cable or plug may be switched.
2. Insufficient shielding of encoder cable against interference.
3. Incorrect encoder parameters set in drive controller.
4. Motor-machine connection loose.
5. Encoder
defective.
1. Check wiring according to connection plan and check state of cables
for damage.
2. Check shielding; if necessary increase effective contact surfaces of
shielding.
3. Correct the parameters. Observe the start-up report for original
values.
4. Check the mechanical connection. Do not continue to use damaged
parts. Contact the machine manufacturer.
5. Change of encoder necessary. Contact the machine manufacturer.
