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 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.
