1. Introduction
Descriptions
The CWD860 is a new generation digital 2-phase stepper motor driver, based on a
32-bit DSP processor, combination of the anti-resonance, low noise, micro-step and
low temperature rise technology significantly improve the performance of the stepper
motor, has low noise, small vibration, low temperature rise and high-speed torque.
The driver use online adaptive PID technology, without manual adjustment can be
automatically generated optimal parameters for different motors, and achieve the best
performance.
Supply voltage range from 20VAC to 60VAC or from 24VDC to 90VDC, suitable for
driving various 2-phase hybrid stepping motors which phase current below 7.2A. The
microstep can be set from full step to 51200steps/rev and the output current can be set
form 2.4A to 7.2A; with automatic idle-current reduction, self-test, overvoltage,
under-voltage and over-current protection


Features
High-performance, low price
micro-step
Automatic idle-current reduction
Optical isolating signals I/O
Max response frequency up to 200Kpps
Low temperature rise, smooth motion
Online adaptive PID technology
Applications
Suitable for a variety of large-scale automation equipments and instruments. For
example: labeling machine, cutting machine, packaging machine, plotter, engraving
machine, CNC machine tools and so on. It always performs well when applied for
equipment which requires for low-vibration, low-noise, high-precision and high-velocity.
