4. ENCODER FEEDBACK CONTROL—A500(L)

The FR-A500(L) series fitted with the FR-A5AP can exercise encoder feedback control.
For the FR-V500 series, vector control can be exercised without the FR-A5AP and encoder feedback
control is not exercised with the FR-A5AP.
This function is used with a speed detector (encoder) 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.
