Technical Manual for EA350 Analog Pulse Type Servo Driver V101 P8-18 bit1: Instantaneous power outage holding function bit1=0: Turn off the instantaneous power outage holding function bit1=1: Turn on the instantaneous outage holding function; it will turn on the outage detection function in default, and shield the alarm within the time set by P8-24. When this function is enabled, even if the main circuit of the driver is out of power, the motor can remain powered on (servo ON) within the time set by P8-24.
When the duration of instantaneous outage is shorter than the value set by P8-24, the motor will remain powered on; otherwise when the duration is greater than the set value, the motor will be powered off, and the driver will be subject to or alarms. 201
