Meaning
Vibration was detected while performing tun-
ing-less function.
The servomotor was operating for several sec-
onds to several tens of seconds under a torque
largely exceeding ratings.
The servomotor was operating continuously
under a torque exceeding ratings.
The heat sink of the SERVOPACK exceeded
90°C.
The power supplies to the encoder all failed and
position data was lost.
The checksum results of encoder memory is
incorrect.
The battery voltage was lower than the specified
value after the control power supply was turned
ON.
Data in the encoder is incorrect.
The encoder was rotating at high speed when
the power was turned ON.
The internal temperature of encoder is too high.
The current detection circuit for phase U is
faulty.
The current detection circuit for phase V is
faulty.
The detection circuit for the current is faulty.
ASIC error occurred in the MECHATROLINK
communications.
ASIC error occurred in the MECHATROLINK
communications.

occurred.
"Internal program error 4" of the SERVOPACK
occurred.
The servomotor ran out of control.
The multiturn for the absolute encoder was not
properly cleared or set.
Communications between the SERVOPACK
and the encoder is not possible.
An encoder position data calculation error
occurred.
An error occurs in the communications timer
between the encoder and the SERVOPACK.
Encoder parameters are faulty.
