3 phase stepping motor Driver YKB3722MA

High performance, low price; Provides 16 kinds of microstep selection,resolution can be set to 60000pulse/rev. Once the pulse stops for 100ms,the phase current will automatically reduce to20%-80%(It can be set by STOP/Im as show as below). Bipolar constant current chopper control. Photocoupler isolated input/output. Adjustable drive current divided into 16 grades range from 0.7A/phase-7A/phase. Single power input, voltage range from AC110V-220V. The upmost pulse response frequence amounts to 200Kpps. Phase memorize(Notes:Once the pulse stops for 5s or more,the Driver will memorize current phases automatically so that it can be resume after restart orMF signal changes from valid to invalid.) Protection circuitOverheat protection;Overcurrent, under voltage protection. Dimension: 80x156x200mm3;Net Weight:2.3Kgs.
