If an error occurs when the main power supply is turned OFF, the operation will be based on the Stop
Selection for Alarm Generation (Pn510). If the main power supply is turned OFF when Servo is ON,
and if the Undervoltage Alarm Selection (Pn508) is set to 1, Err13.1, "main power supply undervoltage
(AC cut-off detection)," will occur. Follow the Stop Selection for Alarm Generation (Pn510).
*1. Immediate stop refers to applying control while servo is still ON and stopping the operation immediately.
At that time, the torque command value is restricted by the Immediate Stop Torque (Pn511).
*2. If the position command is given or the motor runs continuously when the main power supply is turned OFF, the
position error accumulates and Err24.0, "error counter overflow," may occur. In addition, if servo is turned ON when
the position error or external scale error is a large value, the motor may operate abruptly to perform a control operation
to bring the error to 0. Take sufficient care when using while holding the position error or external scale error.
*3. Decelerating refers to a period between when the motor is running and when the motor speed reaches
30 r/min or less. Once the motor reaches a speed of 30 r/min or less and moves to the after stop
status, follow the subsequent operation based on the after stop status regardless of the motor speed.
*4. The position error or external scale error will always be cleared to 0.
