(Note 2) Resetting methods
NR: Reset with the NC RESET button. This alarm can also be reset with the PR and AR resetting conditions.
PR: Reset by turning the NC power ON again. This alarm can also be reset with the AR resetting conditions.
When the control axis is removed, this alarm can be reset with the NC RESET button. (Excluding alarms 32 and 37.)
AR: Reset by turning the NC and servo drive unit power ON again.

Details
A commanded speed exceeding the safely limited speed was
detected in the safely limited mode.
The door state signal input in the NC does not coincide with the
door state signal input in the drive unit in the safely limited mode.
Otherwise, door open state was detected in normal mode.
A motor speed exceeding the safely limited speed was detected
in the safely limited mode.
A contact of the external contactor is welding.
The power supply unit detected an error.
The error details are different according to the connected power supply
unit. Refer to "Power supply alarm" for details.
The cable type of the motor side encoder cable is for rectangular
wave signal.
The cable type of the machine side encoder cable does not
coincide with the encoder type which is set by the parameter.
The drive unit does not operate correctly.
"888" is displayed for MDS-EJ/EJH Series.
The communication data 1 between drivers exceeded the
tolerable value in the communication between drive units.
The communication data 2 between drivers exceeded the
tolerable value in the communication between drive units.
