PID output is restricted to a changeable range based on the target value.
When [AH-71] is 0.00, the function will be disabled.
Precautions for Correct Use
In the case of using this function, set PID1 output range [AH-71]. Restriction will be made in a
range of PID target value ± [AH-71] with the maximum speed as 100%.
Parameter
In normal PID control, the inverter does not output a negative figure for frequency command and limits
at 0 Hz, when result of PID calculation was negative. If you select 02 (with reverse output) for PID1
selection [AH-01], frequency command can be output in a reverse direction, when result of PID calcula-
tion was negative.
Precautions for Correct Use
When [AH-01] is set to 02 (with reverse output), the PID changeable range limit function
[AH-71] will be extended to the negative direction.
This is a function to clear the integral figure of PID operation.
In the case of turning ON the [PIDC] terminal, do so when PID is not in operation.
Precautions for Correct Use
Turning ON the [PIDC] terminal during PID operation clears the integral value added to the PID
output command and changes the PID output command value abruptly, resulting in an
over-current error.
