97 MP scale offset error
9E Absolute position detector, multi-
rotation counter error
9F Battery voltage drop
A8 Turret indexing error warning
A9 Orientation feedback error warn
E1 Overload warning
E3 Absolute position counter warning
E4 Parameter error warning
E6 Control axis removal warning
E7 CNC emergency stop
(Note) SV indicates an alarm for the MDS-C1-V1/V2 unit, and SP indicates an error for the MDS-C1-SP/SPH/SPX/SPHX/SPM
unit.

Resetting methods
* : Automatically reset once the cause of the warning is removed.
NR : Reset with the NC RESET button. This warning can also be reset with the PR and AR resetting conditions.
PR : Reset by turning the NC power ON again. This warning can also be reset with the AR resetting conditions.
When the control axis is removed, this warning can be reset with the NC RESET button. (Excluding warning 93.)
6. Troubleshooting
SV SP
Initial communication with the absolute position linear scale was not
possible.
An error was detected in the communication with the detector for the
absolute position detection system.
An error was detected in the data for the absolute position detection
system.
The position data fluctuated when creating the initial absolute position.
An excessive deviation was detected in the motor end detector and MP
scale feedback data for the MP scale absolute position detection
system.
An error was detected in the offset data received from the MP scale for
the MP scale absolute position detection system.
An error was detected in the multi-rotation counter for the absolute
position detector. The absolute position cannot be compensated.
The voltage of the battery supplying to the absolute position detector
has dropped. The absolute position data is held.
The commanded turret indexing position shift amount is not within the
specified range.
Retrying during an orientation feedback error.
The overload detection level is 80% or more.
A deviation was detected in the absolute position data and absolute
position data.
A parameter exceeding the setting range was set.
Control axis removal was commanded.
Emergency stop was input from the NC.
CV CR
Regeneration at the power supply performance limit is occurring
frequently.
An instantaneous power failure occurred.
The external emergency stop signal was input.
The over-regeneration level is 80% or more.
