This 3 hp, 460 V PWM drive and keypad integrates the control unit and motor into a single package. At constant torque the speed can be varied from 180 r/min to 1800 r/min. Above 1800 r/min - up to a maximum of 3600 r/min - the motor operates in the constant horsepower mode. For optimal performance the carrier frequency can be set to any value between 1125 Hz and 18 kHz, albeit with progressive power derating.
