Meaning
• Setting of AC input/DC input is incorrect.
• Power supply wiring is incorrect.
Main circuit DC voltage is excessively high.
Main circuit DC voltage is excessively low.
The capacitor of the main circuit has deteriorated or
is faulty.
The servomotor speed is above the maximum rota-
tional speed.
The pulse output speed upper limit of the set
encoder output pulse (Pn212) is exceeded.
Incorrect vibration at the motor speed was detected.
Vibration was detected while performing tuning-less
function.
The servomotor was operating for several seconds to
several tens of seconds under a torque largely
exceeding ratings.

rect.
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.
External encoder is faulty.
Serial converter unit is faulty.
External encoder is faulty.
