6 - 35

The communication data 2 between drive units exceeded the tolerable value in the communication between 
drive units.

1

Check if the error was occurred during 
the synchronous tapping.

The error occurs during the synchro-
nous tapping.

[1]Check the tool.
[2]Adjust the tapping.

Check if the error has occurred during 
high-speed synchronous tapping.

Check the investigation item No. 2.

2

Check the repeatability.

The error is always repeated.

Replace the drive unit.

The state returns to normal once, but 
occurs sometimes thereafter.

Check the investigation item No. 3.

3

Check if there is any abnormality in the 
unit's ambient environment.
(Ex. Ambient temperature, noise, 
grounding)

Take remedies according to the causes of the abnormality in the ambient en-
vironment.

An excessive difference in feedback amount was detected between the main side detector and the MPI 
scale in MPI scale absolute position detection system.

1

Check if there is any abnormality in the 
detector's ambient environment.
(Ex. Ambient temperature, noise, 
grounding)

Take remedies according to the causes of the abnormality in the ambient en-
vironment.

2

Check the repeatability.

Occurs frequently.

Replace the detector.

Is not repeated.

Check the investigation item No. 1.

An error was detected in the offset data that is read at the NC power-ON in MPI scale absolute position 
detection system.

1

Check if there is any abnormality in the 
detector's ambient environment.
(Ex. Ambient temperature, noise, 
grounding)

Take remedies according to the causes of the abnormality in the ambient en-
vironment.

2

Check the repeatability.

Occurs frequently.

Replace the detector.

Is not repeated.

Check the investigation item No. 1.

For the incremental detector, an error was detected in the magnetic pole shift amount set in the magnetic 
pole shift amount parameter "SV028".

1

Check if there is any abnormality in the 
detector's ambient environment.
(Ex. Ambient temperature, noise, 
grounding)

Take remedies according to the causes of the abnormality in the ambient en-
vironment.

2

Check the repeatability.

Occurs occasionally.

Execute magnetic pole detection con-
trol again and reset SV028.

Is not repeated.

Check the investigation item No. 1.

An error was detected in the revolution counter of the absolute position detector. The absolute position data 
cannot be compensated.

1

Check if there is any abnormality in the 
detector's ambient environment.
(Ex. Ambient temperature, noise, 
grounding)

Take remedies according to the causes of the abnormality in the ambient en-
vironment.

2

Check the repeatability.

Occurs frequently.

Replace the detector.

Is not repeated.

Check the investigation item No. 1.
