5.14.12 PID Pre-charge function

This function drives the motor at a certain speed before starting PID control. This function is useful for a pump with a long hose,
since PID control would start before the pump is filled with water, and proper control would not be performed without this
function,

Setting
range
Fault indication with output shutoff immediately after pre-charge fault
occurs.
Fault indication with deceleration stop after pre-charge fault occurs.
Set the measured amount to end the pre-charge operation.
Without pre-charge ending level
Set the time to end the pre-charge operation.
Without pre-charge ending time
Set the upper limit for the pre-charged amount. A pre-charge fault
occurs when the measured value exceeds the setting during pre-
charging.
Without Pre-charge upper detection level
Set the time limit for the pre-charged amount. A pre-charge fault occurs
when the pre-charge time exceeds the setting.
