The PID Acc. /Dec. time is used for the PID target.
When the PID target changes quickly, the normal C1-□□ Acc. time decreases the response
since it is applied after the PID output. This PID Acc./Dec. time prevents the overshoot,
undershoot and hunting caused by the decreased response. In addition, set a lower value to
parameter group C1 to avoid hunting. This parameter will be disabled if a multi-function input
is assigned to E1-□□= 49 (PID Soft-Start On/Off).
