PARAMETERS
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.
