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.

H50

[PID Feedback Selection]

Terminal I input (0 to 20[mA] )

Terminal V1 input (0 to 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 SV-iG5A. 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, H56: Limits the output of the PID controller.

I17 to I24: To go from PID to normal operation, set one of P1-P8 terminal to 21 and turn ON.

d1: Calculates the feedback from H50 into Motor frequency and displays it.
