M800/M80/E80/C80 Series Alarm/Parameter Manual
3 Servo/Spindle Alarms (S)
49
IB-1501279-H
(Note 1) Definitions of terms in the table are as follows.
Main side encoder: Encoder connected to CN2
Sub side encoder: Encoder connected to CN3
(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.
No.

46 Motor overheat /
Thermal error
Either the motor or the motor side encoder detected an
overheat.
Or, the thermistor signal receiving circuit of the linear motor or
direct-drive motor was disconnected.
Or, the thermistor signal receiving circuit was short-circuited.
