(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
An error was detected by the encoder connected to the machine side.
The error details are different according to the encoder type.
Refer to "Encoder alarm" for details.
The error details are different according to the encoder type.
Refer to "Encoder alarm" for details.
An error was detected in the communication with the motor side
encoder.
Over-regeneration level exceeded 100%. The regenerative
resistor is overloaded.
The motor speed exceeded the allowable speed.
The power module detected the overcurrent.
The bus voltage in main circuit exceeded the allowable value.
The data received from the NC was outside the setting range.
The travel command data received from the NC was excessive.
The communication with the NC was interrupted.
An incorrect set value was detected among the parameters
send from the NC at the power ON.
In the SLS(Safely Limited Speed) function, an error was
detected in the relation between the safety speed and safety
rotation number in the speed observation mode.
An error was detected in the communication frames received
from the NC.
Or, removing an axis or changing an axis was performed in the
synchronous control.
An error was detected in the axis data received from the NC.
Or, in changing an axis, the parameter setting of the
synchronous control was applied when the axis was installed.
Excessive motor drive current was detected.
The power module detected an overheat.
An error was detected in the regenerative transistor or in the
regenerative resistor.
A motor control error during acceleration/deceleration, due to a
power voltage failure, was detected.
The magnetic pole position, detected in the magnetic pole
position detection control, is not correctly detected.
