Details
Undervoltage The power voltage is 160V or less.
Regeneration The tolerable regeneration power of
error the internal regenerative resistor or
external regenerative option was
exceeded.
Regenerative transistor error
Overspeed The motor's speed exceeded the
tolerable momentary speed.
Overcurrent A current exceeding the servo
amplifier's tolerable current flowed.
Overvoltage The voltage of the converter in the
servo amplifier was 400V or more.
Motor An operation state causing the
overheating motor to overheat continued.
Overload 1 The servo amplifier or servomotor
overload protection function
activated.
