Specifications
This application performs principal control 3-phase induction motor using 56F805 processor. control technique sets speed (rpm magnetic field calculates phase voltage amplitude according V/Hz table. This table private application reflects induction motor parameters (Base Voltage/frequency; Boost Voltage/frequency; Boost Voltage). incremental encoder used derive actual rotor speed. closed-loop system characterized feedback signal (Actual speed), derived from quadrature decoder controlled system. This signal monitors actual behavior system, compared with reference signal (Required Speed). magnitude polarity resulting error signal directly related difference between required actual values controlled variable, which speed motor. error signal amplified controller, controller output makes correction controlled system, reducing error signal. Protection provided against drive faults Overcurrent, Overvoltage, Undervoltage, Overheating.
