PID control
Pre-charge operation at output shutoff
When the pre-charge operation is valid, the pre-charge operation is performed at the output shutoff cancellation.
(The pre-charge operation is also performed even if the automatic restart after instantaneous power failure is valid.)
When the operation method is changed to PID control from another control
When the control method is changed to PID control from a control with higher priority in frequency command (multi-
speed setting, Jog operation, etc.), the motor is accelerated/decelerated until its speed reaches the automatic
switchover frequency, and the pre-charge is performed.
When the output is shutoff during PID control, which is performed after the pre-charge operation
When the output is shutoff during the pre-charge operation
REMARKS
If the output shutoff is canceled while the X77 signal is ON, the pre-charge operation is not performed and PID control is
performed.
