Fairdeal instrument & controls presents eric inverters [90001 series]. These inverters are general-purpose inverters with flux vector control that directly control the current [or torque] in an ac induction motor, suitable for any application. These inverters provide smooth start-up at low speeds and precise operation. The auto-tuning function enables high-performance tuning of all induction motors. The inverters combine four control methods, viz, open loop rector, flux vector, v/f control with pg feedback and v/f control. From precision machinery to multiple motor drives, the inverters prove to be the ultimate drive for all applications. Some of the features which allows the motor to do the utmost are 32 bits, dsp microprocessor configuration, magnetic field oriented flux vector control, auto-tune ability, available for speed-type servo controller while pg feedback added, rs-232/ rs-485 serial communication port, optional ac reactors available, capacities from 1 hp up to 400 hp, etc.
