Brief Introduction
2MSD4250 is a low cost high performance microstepping drive, it is suitable for driving any 2-phase and 4-phase hybrid step motors of NEMA17, 23, and 34 with up to 4.2A per phase current capability.
Based on the build-in bi-polar constant chopping technology, the stepper motor can work with more speed and power. The input voltage ranges from 12VDC – 50VDC. The driver reduces the current through the coils automatically to 50% after 1 second of receiving the last step pulse, this reduces the heating of both the driver and motor by 75%.
Features
- Low cost, high performance
- Low noise, high stability
- 15 selectable resolutions, the maximum of 128 microsteps gives smooth and precise rotation.
- Special control circuit lowers noise and enhances stability
- Bi-polar constant chopping technology provides high speed and power
- Opto-isolated input/output signals, pulse frequency 400Khz
- Automatic idle-current reduction
- DIP switch current setting with 8 different value, up to 4.2A peak
- Input voltage from 20VDC to 50VDC
- Short-circuit and over-voltage protection, LED turn to RED when voltage high than 52VDC.
- Compact, size is just 118 x 75.5 x 33 mm.
Applications
2MSD4250 can be used for 2-phase hybrid stepping motors of NEMA17, 23 and 34 with a phase current of up to 4.2A, it’s suitable for a wide range of machines, such as X-Y tables, labeling machines, laser cutters, engraving machines, and pick-place devices.
