1 Introduction
The MD24 / MD28 are economical microstepping driver based on patented technology. It
is suitable for driving 2-phase and 4-phase hybrid stepping motors. By using the
advanced bipolar-current chopping technique, it can output more speed and torque from
the same motor, compared with traditional drivers, such as L/R drivers. Its 3-state current
control technology allows coil currents to be well controlled and with relatively small
current ripple, therefore less motor heating is achieved.
Features:
- Low cost and good high-speed torque
- Optically isolated input signals
- Pulse frequency up to 300 KHz
- Automatic idle-current reduction
- 3-state current control technology
- High resolution Microstepping
- Suitable for 2-phase and 4-phas motors
- DIP-Switch setting
- Over-voltage and short-circuit protection
Small size
Suitable for a wide range of stepping motors from Nema size 17 to 34. It can be used in
various kinds of machines, such as X-Y tables, labeling machines, laser cutters, engraving
machines, pick-place devices, and so on. Particularly adapt to the applications desired with
low vibration, high speed and high precision.
