DM542
Digital two-phase stepper driver
一、Introduction
1. Overview
DM542 is the new digital stepping motor driver of our company. It adopts the latest 32-bit DSP
digital processing technology. The driver control algorithm uses advanced variable current
technology and advanced frequency conversion technology.
The driver has low heat generation,
small motor vibration and stable operation. Users can set any subdivision within 200~51200 and
any current value within the rated current, which can meet the application needs of most occasions.
With built-in micro-segmentation technology, even in the case of low subdivision, high subdivision
can be achieved, and the operation at low, medium and high speeds is smooth and the noise is
extremely small.
The parameter internal power-on auto-tuning function is integrated in the drive,
which can automatically generate optimal operating parameters for different motors to maximize
the performance of the motor.
2. Features
3. Application field
Suitable for all kinds of small and medium-sized automation equipment and instruments, such as:
engraving machine, marking machine, cutting machine, laser phototypesetting, plotter, CNC
machine tool, automatic assembly equipment, etc. It is especially effective in applications where
users expect small noise and high speed.
