Overview
CWD2208 Step Motor Driver
The CWD2208 is a new generation digital 2-phase stepper motor driver, based on a 32-bit DSP processor, combination of anti-resonance, low noise, micro-step and low temperature rise technology significantly improves the performance of the stepper motor reducing noise, vibration and temperature rise while providing high-speed torque . The driver uses online adaptive PID technology, without manual adjustment, it can automatically generate optimal parameters for different motors, and achieve the best performance.
Supply voltage ranges from 110VAC to 220VAC, suitable for driving various 2-phase hybrid stepping motors which phase current below 8.2A. The microstep can be set from full step to 51,200steps/rev and the output current can be set form 2.2A to 8.2A. Designed with automatic idle-current reduction, self-test, overvoltage, under-voltage and over-current protection.
Key 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 large-scale automation equipment and instruments. For example: labeling machines, cutting machines, packaging machines, plotters, engraving machines, CNC machine tools and so on. It always performs well when applied to equipment that requires low-vibration, low-noise, high-precision and high-velocity.

Standstill Current Setting
SW4 is used for standstill current setting. OFF meaning that the standstill current is half of the dynamic current; and ON meaning that standstill current is the same as the selected dynamic current. Usually the SW4 is set to OFF, in order to reduce the heat of the motor and driver.
