Mitsumi electronic FR-F520-0.75K PID control Pr to Pr, Setting Basic PID control configuration

PARAMETERS

4.2.40 PID control (Pr. 128 to Pr. 134)

Pr. 128 "PID action selection"

Pr. 129 "PID proportional band"

Pr. 130 "PID integral time"

Pr. 131 "upper limit"

Pr. 132 "lower limit"

Pr. 133 "PID action set point for PU operation" Pr. 134 "PID differential time"

Related parameters

Pr. 73 "0-5V/0-10V selection"

Pr. 79 "operation mode selection" Pr. 180 to Pr. 186

(input terminal assignment) Pr. 190 to Pr. 195

(output terminal assignment) Pr. 500 to Pr. 516

(Advanced PID control) (NA, EC versions only)

Pr. 902 to Pr. 905 (frequency setting voltage (current) biases and gains)

The inverter can be used to exercise process control, e.g. flow rate, air volume or pressure.

#The voltage input signal (0 to ± 5V or 0 to ± 10V) or Pr. 133 setting is used as a set point and the 4 to 20mADC current input signal used as a feedback value to constitute a feedback system for PID control.

#Refer to page 145 for advanced PID control. (NA, EC versions only)
