・The PID1 function is enabled with the above parameter.
・If [AH-01]=01 when the PID output reaches negative value, the
PID output is limited to 0.
・If [AH-01]=02 when the PID output reaches negative value, the
PID output lets out an inverted output.
・When the PID output is negative, the motor will rotate in the
contrary direction.
・If input terminal 041[PID] is ON, the PID control is disabled
and the PID target value becomes the frequency reference.

・The unit and display data related to the output of the PID
control can be changed.
・PID1 is capable of 3 target value inputs and 3 feedback inputs,
and various operations can be performed with [AH-50] and
[AH-54].
■ When AH-50 = 01 to 04 ( + , - , ×, / ) , the operation target is
PID1 set-point 1 (select from [AH-07] and [AH-10] to [AH-40])
and PID1 set-point 2 (selected with [AH-42]).
