Meaning
EEPROM data of Servopack is abnormal.
Detection data for power circuit is abnor-
mal.
The user constant setting is outside the al-
lowable setting range.
Servopack and Servomotor capacities do no
match each other.
An overcurrent flowed through the IGBT.
Heat sink of Servopack was overheated.
S Regenerative circuit is faulty
S Regenerative resistor is faulty.
Regenerative energy exceeds regenerative
resistor capacity.
Main circuit DC voltage is excessively high.
Main circuit DC voltage is excessively low.
Rotational speed of the motor is excessively
high.
The motor was operating for several sec-
onds to several tens of seconds under a
torque largely exceeding ratings.
The motor was operating continuously un-
der a torque largely exceeding ratings
When the dynamic brake was applied, rota-
tional energy exceeded the capacity of dy-
namic brake resistor.
The main circuit power was frequently
turned ON and OFF.
The heat sink of Servopack overheated.
