The IMT 901 is a PWM chopper type sinusoidal micro step bipolar stepp-
ping motor driver. Sinusoidal micro step operation is generated by means
of built-in hardware and is outputted for operation by clock signal inputting.
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 stand-
still
