setting or higher, the pre-charge operation
ends, and PID control starts.
Pr. 761 Pre-charge ending level

When the pre-charging time reaches the Pr. 762
setting or higher, the pre-charge operation
ends, and PID control starts.
Pr. 761 Pre-charge ending level
Pr. 762 Pre-charge ending time
When the X77 signal turns ON, the pre-charge
operation ends, and the PID control starts.
(If a start command is given while the X77
signal is ON, the pre-charge operation is not
performed, and PID control is performed from
the beginning. )

REMARKS
 If the X77 signal stays ON, the pre-charge
operation is not performed after the PID
output suspension (SLEEP). To enable the
X77 signal function after the PID output
suspension (SLEEP), confirm the during pre-
charge operation signal (Y49) = OFF, and
turn OFF the X77 signal.
 To perform PID control immediately after the
PID output suspension (SLEEP), keep the
X77 signal ON until the PID control ends.
