I.PLG FEEDBACK CONTROL
4. PLG FEEDBACK CONTROL
This function is used with a speed detector (PLG) to allow the motor speed to be detected by the speed detector and
fed back to the inverter so that the output frequency of the inverter is controlled to keep the motor speed constant to
load variations. Pr. 367 "speed feedback range" is factory-set to "9999" and Pr. 370 "control mode selection" to "0",
making this function invalid.
