 If an alarm occurs when the main power supply is turned OFF, the operation will be based on the Stop
Selection for Alarm Detection (Pn510). If the main power supply is turned OFF when Servo is ON,
and if the Undervoltage Alarm Selection (Pn508) is set to 1, Alarm 13.1, "main power supply
undervoltage (AC cut-off detection)," will occur. Follow the Stop Selection for Alarm Detection
(Pn510).
The dynamic brake is designed only for emergency stopping. Design the system to stop within
about ten minutes after the dynamic brake operates.
*1. Emergency stop refers to an immediate stop operation 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 Alarm 24.0, "error counter overflow," may occur. In addition, if servo is turned ON when
the position error or external encoder 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 encoder
error.
*3. Decelerating is the time between when the motor is running and when the motor speed reaches 30 r/
min or less. Once the motor reaches 30 r/min or less and moves to the after-stop status, subsequent
operation is based on the after-stop status regardless of the motor speed.
*4. The position error or external encoder error will always be cleared to 0.
