(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.

41 Feedback error 3
Either a missed feedback pulse in the motor side encoder or an
error in the Z-phase was detected in the full closed loop system.
PR
Dynamic stop Coast to a stop
42 Feedback error 1
Either a missed feedback pulse in the position detection or an
error in the Z-phase was detected. Or the distance-coded refer-
ence check error exceeded the allowable value when the dis-
tance-coded reference scale was used.
PR
Dynamic stop Coast to a stop
43 Feedback error 2
An excessive difference in feedback was detected between the
machine side encoder and the motor side encoder.
PR
Dynamic stop Coast to a stop
45 Fan stop
An overheat of the power module was detected during the cool-
ing fan stopping.
PR
Dynamic stop Coast to a stop
46 Motor overheat /
Thermal error
Either the motor or the motor side encoder detected an over-
heat.
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.
