Alarm Content
Abnormal oscillation was detected in the motor
speed.
Vibration was detected during autotuning for the
tuning-less function.
The setting of Pn385 (Maximum Motor Speed) is
greater than the maximum motor speed.
The Servomotor was operating for several seconds
to several tens of seconds under a torque that largely
exceeded the rating.
The Servomotor was operating continuously under
a torque that exceeded the rating.
When the dynamic brake was applied, the rotational
or linear kinetic energy exceeded the capacity of the
dynamic brake resistor.
The main circuit power supply was frequently
turned ON and OFF.
The heat sink of the SERVOPACK exceeded
100°C.
The surrounding temperature of the control PCB is
abnormal.
The surrounding temperature of the power PCB is
abnormal.
An error occurred in the temperature sensor circuit.
The fan inside the SERVOPACK stopped.
The power supplies to the encoder all failed and the
position data was lost.
There is an error in the checksum results for
encoder memory.
The battery voltage was lower than the specified
level after the control power supply was turned ON.
There is an internal data error in the encoder.
The encoder was operating at high speed when the
power was turned ON.
The internal temperature of the rotary encoder or
linear encoder is too high.
The internal temperature of motor is too high.
A failure occurred in the linear encoder.
An error occurred in the linear encoder.
An error occurred in the external encoder.
An error occurred in the Serial Converter Unit.
An error occurred in the external encoder.
An error occurred in the position data of the exter-
nal encoder.
An overspeed error occurred in the external
encoder.
An overheating error occurred in the external
encoder.
An error occurred in the A/D converter for the
speed reference input.
An error occurred in the A/D conversion data for
the speed reference.
An error occurred in the A/D converter for the
torque reference input.
The current detection circuit for phase U is faulty.
