List of alarms

When an alarm occurs, the servo drive unit will make the motor stop by the deceleration control or
dynamic brake. The spindle drive unit will coast to a stop or will decelerate to a stop. At the same time,
the alarm No. will appear on the NC monitor screen and with the LEDs on the front of the drive unit.
Check the alarm No., and remove the cause of the alarm by following this list.

(Note 2) 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.
6. Troubleshooting
SV SP
The axis No. selection switch setting is incorrect.
A CPU or internal memory error was detected during the self-check at
power ON.
The software process was not completed within the specified time.
(CPU1)
The software process was not completed within the specified time.
(CPU2)
Creation of the initial magnetic pole, required for motor control, was not
completed.
An error was detected in the A/D converter for current FB detection.
Initial communication with the motor end detector was not possible.
Initial communication with the master axis motor end detector was not
possible when the closed current command synchronous control was
set. Or, the communication was cut off.
Initial communication with the linear scale or ball screw end detector
was not possible.
A CPU initial error was detected with the linear scale or ball screw end
detector.
An error was detected in the data stored in the memory with the linear
scale. Or, LED deterioration was detected with the linear scale.
A data error was detected with the linear scale or ball screw end
detector.
An internal memory error was detected with the linear scale.
An error was detected in the communication data with the linear scale
or ball screw end detector. Or, the communication was cut off.
