Meaning
Detected when the power to the main circuit is
turned ON.
Main circuit DC voltage is excessively high.
Main circuit DC voltage is excessively low.
The capacitor of the main circuit has deterio-
rated or is faulty.
The servomotor speed is excessively high.
The motor speed upper limit of the set
encoder output pulse (pulse unit) (Pn212) is
exceeded.
Vibration at the motor speed was detected.
Vibration was detected while performing tun-
ing-less function.
The Pn385 setting is greater than the maxi-
mum speed.
The motor was operating for several seconds
to several tens of seconds under a force
largely exceeding ratings.
The motor was operating continuously under a
force largely exceeding ratings.
When the dynamic brake was applied, moving
energy exceeded the capacity of dynamic
brake resistor.
The main circuit power was frequently turned
ON and OFF.
The heat sink of the SERVOPACK exceeded
100°C.
The fan inside the SERVOPACK stopped.
The checksum results of encoder memory is
incorrect.
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.
A linear scale fault occurred.
Encoder module is faulty.
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 MECHA-
TROLINK communications.
"Internal program error 0" of the SERVO-
PACK occurred.
"Internal program error 1" of the SERVO-
PACK occurred.
"Internal program error 2" of the SERVO-
PACK occurred.
