PID1 function
Code/Name
AH-01
PID1 enable
02(Enable:inverted output)
・Validates the PID1 operation.
・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 [PID] terminal is ON, the PID control is disabled and
the [PID] target value becomes the frequency
reference.

・For PID1 target value, two targets are selected, target value 1 and
target value 2, the result of the operation carried out between these
two targets constitutes the PID1 target value.
・If Input terminal function 051[SVC1]～054[SVC4] are used, the PID
target value can be changed for the Multistage.
