ENCODER FEEDBACK CONTROL

Mount FR-A8TP to an FR-A800 series inverter to perform encoder feedback control under V/F control or Advanced magnetic
flux vector control.
This controls the inverter output frequency so that the motor speed is constant to the load variation by detecting the motor
speed with the speed detector (encoder) to feed back to the inverter.
For the details of the parameters used for encoder feedback control, refer to the Instruction Manual (Detailed) of the inverter.
