Mar 08, 2002 i Drive digital servo drives are point-to-point digital amplifiers available in 7 models with power ratings from 0.5 to 3 kW (1- or 3-phase). Drives can be used for velocity, torque, and position control of synchronous and asynchronous motors. They offer Digital Signal Processing (DSP) technology based on vector-based sensorless field algorithm. LCD display and 6 function/programming pushbuttons allow for entering parameters, set points, and error flags.
