Alarm Meaning
There is an error in the parameter data in
the SERVOPACK.
There is an error in the parameter data
format in the SERVOPACK.
There is an error in the parameter data in
the SERVOPACK.
An internal program error occurred in the
SERVOPACK.
An internal program error occurred in the
SERVOPACK.
There is an error in the detection data for
the main circuit.
A parameter setting is outside of the set-
ting range.
The setting of Pn212 (Encoder Output
Pulses) or Pn281 (Encoder Output Reso-
lution) is outside of the setting range or
does not satisfy the setting conditions.
The combination of some parameters
exceeds the setting range.
The settings of the Option Module and
Pn002 = n.X (External Encoder
Usage) do not match.
There is an error in setting of parameters
reserved by the system.
The capacities of the SERVOPACK and
Servomotor do not match.
An unsupported device was connected.
The connected motor is a different type of
motor from the previously connected
motor.
The setting of Pn282 (Linear Encoder
Pitch) has not been changed from the
default setting.
The /S-ON (Servo ON) signal was input
from the host controller after a utility func-
tion that turns ON the Servomotor was
executed.
An overcurrent flowed through the power
transformer or the heat sink overheated.
The current to the motor exceeded the
allowable current.
There is an error related to regeneration.
A regenerative overload occurred.
• The AC power supply input setting or
DC power supply input setting is not
correct.
• The power supply wiring is not correct.
