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 linear servomotor speed is over the maximum allowable
speed.
The set value of the encoder output resolution (Pn281)
exceeds the speed limit.
Vibration at the motor speed was detected.
Vibration was detected while performing tuning-less func-
tion.
The linear servomotor was operating for several seconds to
several tens of seconds under a force largely exceeding rat-
ings.
The linear servomotor 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 temperature of the SERVOPACK heat sink exceeded
100°C.
The fan inside the SERVOPACK stopped.
The checksum results of linear scale memory is incorrect.
Data in the linear scale is incorrect.
