Two Phase Digital Hybrid Stepper Motor Driver For CNC Machine
Descriptions
The CW422C 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 18VDC to 40VDC, suitable for driving various 2-phase hybrid stepping motors which phase current below 2.2A. The microstep can be set from full step to 6400steps/rev and the output current can be set form 0.5A to 2.2A; with automatic idle-current reduction, self-test, overvoltage, under-voltage and over-current protection.
Features
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.

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.
