IMT901

Drivers www.DataSheet4U.com IMT-901 - Microstep Constant Current Driver “IC” The IMT 901 is a PWM chopper type sinusoidal micro step bipolar steppping motor driver. Sinusoidal micro step operation is generated by means of built-in hardware and is outputted for operation by clock signal inputting. Advantages: only one IC for power and logic (up to 2,5 A/phase) reduces considerably space, assembly time and cost of a microstep driver with a max. functions yet with a min. of ext. components. selectable from: 1/1-, 1/2-, 1/4-, 1/8-Step enables individual application-related microstep switching, smooth and constant running and reduces considerably system resonance. Current down system or current zeroing reduces or eliminates motor power losses and heating during standstill Dimensions (mm) PIN-Assignment max.
