1. Introduction, Features and Applications
Introduction
The ME432 is an economical microstepping driver based on patented technology of Leadshine. It
is suitable for driving 2-phase and 4-phase hybrid stepping motors. By using the advanced bipolar
constant-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
l Low cost and good high-speed torque
l Supply voltage up to +40VDC
l Output current up to 3.2A
l Optically isolated input signals
l Pulse frequency up to 200 KHz
l Automatic idle-current reduction
l 3-state current control technology
l 15 selectable resolutions
l Suitable for 2-phase and 4-phas motors
l DIP switch current setting with 8 different
values
l CW/CCW mode available (optional)
l Over-voltage and short-circuit protection
l Small size (115*67.7*25mm)
Applications
Suitable for a wide range of stepping motors from Nema size 16 to 23. 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.

*Recommended to use side mounting for better heat dissipation
Elimination of Heat
l Driver ’ s reliable working temperature should be <65 , and motor working temperature should ℃
be <80 ; ℃
l Recommend use automatic idle-current reduction mode, namely current automatically be
reduced to 60% when motor stops, so as to reduce driver heating and motor heating;
l Recommend use side mounting to maximize heat sink area.
