Set H40 to 2 {PID Feedback control}.

Output frequency of the inverter is controlled by PID control for use as constant control of
flow, pressure or temperature.
H50: Select the feedback type of PID controller.
0 Terminal I input (0 ~ 20[mA] )
H50 [PID Feedback
select]
1 Terminal V1 input (0 ~ 10[V])
H51: Set the percentage of output to error. If P Gain is set to 50%, 50% of the error
value will be output. Higher value can reach the target control value faster but it may
cause oscillation.
H52: Set the time to output the accumulated error value. Set the time required to
output 100% when the error value is 100%. If H52 - [Integral time for PID controller (I
gain)] is set to 1 sec and the error becomes 100%, 100% will be output in 1 sec.
Adjusting the value may reduce the nominal error. If the value is reduced, response will
be faster but setting too low may lead to controller oscillation.
H53: Set the output value to the variation of the error. The error is detected by 0.01
sec in GS. If differential time is set to 0.01 sec and the percentage variation of error per
1 sec is 100%, 1% per 10msec is output.
H54: PID Feed Forward Gain. Set the gain to add the target value to the PID
controller output.
H55: It limits the output of the PID controller.
I17 ~ I24: To exchange PID to normal operation, set one of P1-P8 terminal to 21 and
turn ON.
rPM: Calculates the feedback from H50 into Motor RPM and displays it.
