(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.
Details
A drop of bus voltage was detected in main circuit.
The axis selection rotary switch has been incorrectly set.
A hardware error was detected during the power ON self-check.
In the built-in motor which uses the absolute position encoder,
the servo ON has been set before the magnetic pole shift
amount is set.
The magnetic pole position, detected in the initial magnetic pole
position detection control, is not correctly set.
A current feedback error was detected.
An error was detected in the initial communication with the
motor side encoder.
An error of the shared encoder on the machine side was
detected on the secondary axis of the speed command
synchronization control.
An error was detected in the initial communication with the
machine side encoder.
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.
An error was detected in the communication with the machine
side encoder.
In the machine side encoder, ABZ-phase feedback cannot be
returned even when the motor moves.
An error was detected in the feedback data from the position
encoder.
The state that there is a difference between the actual speed
and command speed continued for longer than the excessive
speed deviation timer setting.
The motor power cable is in contact with FG (Frame Ground).
The absolute position data was lost in the encoder.
In the multiaxis drive unit, there is an axis set to free, and the
other axis detected a power module error.
