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.
H52 : Set the time needed 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,
100% is output in 1 sec.
H53 : Set the output value corresponding to the variation of the error. The error is detected by 0.01
sec in SV-iC5. If differential time is set to 0.01 sec and the percentage variation of error is 100 per 1
sec, 1% in 100% is output per 10msec.
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.
I20~I24: To exchange PID, set one of P1-P5 terminal to 21 and turn ON.
