Meaning
An overcurrent flowed through the IGBT or the heat sink of the
SERVOPACK was overheated.
The currents in the motor windings are not correct.
Regenerative circuit or regenerative resistor is faulty.
Regenerative energy exceeds regenerative resistor capacity.
• 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.
One of the following was detected by the converter.
• An operation error occurred when using the limit relay for inrush
current
• PN voltage error
• Regeneration operation error
• The converter's heat sink overheated
• An operation error occurred when using the converter and fan
The capacitor of the main circuit has deteriorated or is faulty.
The servomotor speed is above the maximum rotational speed.
The pulse output speed upper limit of the set encoder output pulse
(Pn212) is exceeded.
Incorrect vibration at the motor speed was detected.
The servomotor was operating for several seconds to several tens of
seconds under a torque largely exceeding ratings.
The servomotor was operating continuously under a torque exceed-
ing ratings.
When the dynamic brake was applied, rotational 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 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 con-
trol power supply was turned ON.
Data in the encoder is incorrect.
The encoder was rotating at high speed when the control power sup-
ply 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.
