Alarm Meaning
The surrounding temperature of the power PCB
is abnormal.
An error occurred in the temperature sensor cir-
cuit.
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).
A failure occurred in the linear encoder.
An error occurred in the linear encoder.
An error occurred in the current detection circuit.
ASIC error 1 occurred in MECHATROLINK com-
munications.
