Remedies
SV SP
1
Check if there is any abnormality in the encoder's
ambient environment.
(Ex. Ambient temperature, noise, grounding)
Take remedies according to the causes of the abnormality in the ambient environment.
◯
2
Check the repeatability.
Occurs frequently.
Replace the encoder.
◯
◯
Is not repeated.
Check the investigation item No. 1.
Warning No.
97
Scale offset error
An error was detected in the offset data that is read at the NC power-ON in MPI scale absolute position detection system.
