(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.

27 Sub side encoder: Error 5 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. Dynamic stop Coast to a stop
28 Sub side encoder: Error 6
29 Sub side encoder: Error 7
2A Sub side encoder: Error 8
2B Main side encoder: Error 1 An error was detected by the encoder connected to the motor side.
The error details are different according to the encoder type.
Refer to "Encoder alarm" for details.
Dynamic stop Coast to a stop
2C Main side encoder: Error 2
2D Main side encoder: Error 3
2E Main side encoder: Error 4
2F Main side encoder:
Communication error
An error was detected in the communication with the motor side
encoder. PR Dynamic stop Coast to a stop
30 Over regeneration Over-regeneration level exceeded 100%. The regenerative re-
sistor is overloaded. PR Dynamic stop Coast to a stop
31 Overspeed The motor speed exceeded the allowable speed. PR Deceleration

32 Power module error
(overcurrent)
The power module detected the overcurrent. PR Dynamic stop Coast to a stop
33 Overvoltage The bus voltage in main circuit exceeded the allowable value. PR Dynamic stop Coast to a stop
34 NC communication:
CRC error
The data received from the NC was outside the setting range. PR Deceleration
stop
Deceleration
stop
35 NC command error The travel command data received from the NC was excessive. PR Deceleration
stop

36 NC communication:
Communication error
The communication with the NC was interrupted. PR Deceleration
stop
Deceleration
stop
37 Initial parameter error 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 detect-
ed in the relation between the safety speed and safety rotation
number in the speed observation mode. PR Initial error Initial error
38 NC communication:
Protocol error 1
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. PR Deceleration
stop
Deceleration
stop
39 NC communication:
Protocol error 2
An error was detected in the axis data received from the NC.
Or, in changing an axis, the parameter setting of the synchro-
nous control was applied when the axis was installed. PR Deceleration
stop
Deceleration
stop
3A Overcurrent Excessive motor drive current was detected. PR Dynamic stop Coast to a stop
3B Power module error
(overheat)
The power module detected an overheat. PR Dynamic stop Coast to a stop
3C Regeneration circuit error An error was detected in the regenerative transistor or in the re-
generative resistor. PR Dynamic stop -
3D Power supply voltage error
at acceleration/deceleration
A motor control error during acceleration/deceleration, due to a
power voltage failure, was detected. PR Dynamic stop -
3E Magnetic pole position de-
tection error
The magnetic pole position, detected in the magnetic pole posi-
tion detection control, is not correctly detected. AR Dynamic stop Coast to a stop
