Alarm Meaning
The Servomotor was operating for several
seconds to several tens of seconds under
a torque that largely exceeded the rating.
The Servomotor was operating continu-
ously 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 fre-
quently turned ON and OFF.
The surrounding temperature of the con-
trol PCB is abnormal.
The surrounding temperature of the
power PCB is abnormal.
An error occurred in the temperature sen-
sor 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 encoder is
too high.
The internal temperature of motor is too
high.
The input voltage (temperature) for the
overheat protection input (TH) signal
exceeded the setting of Pn61B (Overheat
Alarm Level).
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 external encoder.
An overspeed error occurred in the exter-
nal encoder.
An overheating error occurred in the
external encoder.
