7.3.3 Troubleshooting for Each Warning No.

Scale feedback error
Warning No.
An excessive difference in feedback amount was detected between the main side encoder and the MPI scale in MPI scale
96
absolute position detection system.
Investigation details
Check if there is any abnormality in the encoder's
1 ambient environment.
(Ex. Ambient temperature, noise, grounding)
2 Check the repeatability.
Warning No.
Scale offset error
97
An error was detected in the offset data that is read at the NC power-ON in MPI scale absolute position detection system.
Investigation details
Check if there is any abnormality in the encoder's
1 ambient environment.
(Ex. Ambient temperature, noise, grounding)
2 Check the repeatability.
Incremental encoder/magnetic pole shift warning
Warning No.
For the incremental encoder, an error was detected in the magnetic pole shift amount set in the magnetic pole shift amount
9B
parameter "SV028".
Investigation details
Check if there is any abnormality in the encoder's
1 ambient environment.
(Ex. Ambient temperature, noise, grounding)
2 Check the repeatability.
Absolute position encoder: Revolution counter error
Warning No.
An error was detected in the revolution counter of the absolute position encoder. The absolute position data cannot be
9E
compensated.
Investigation details
Check if there is any abnormality in the encoder's
1 ambient environment.
(Ex. Ambient temperature, noise, grounding)
Check if there is any liquid ingress inside the
2
encoder connector.
3 Check the repeatability.
