Descriptions
The CW230 driver is a cost-effective and high performance stepping driver. The design is based
on an advanced control technology. It applies to two-phase or four-phase hybrid stepping motor
below 3A,such as 57BYG,42BYG. Due to the adoption of the advanced bipolar constant-current
chopper driver technology. It shows many features such as stable operation and excellent high speed
torque. It has 7 kinds of micro-step, and the maximum number of micro-step is 1/64. Chopping
frequency of 20000 times per second can eliminate the noise of the motor. Another unique function
is that it can automatically reduce current: when the motor is stopped, the output current reduces to a
lower value, thereby reducing the heating of the motor and driver.
Supply voltage range from 18VDC to 40VDC ,the output current can be set from 0.9A to 3A;
with automatic idle-current reduction, self-test, over-voltage, under-voltage and over-current
protection.

Features
High-performance, low price
micro-step
Automatic idle-current reduction
Optical isolating signal I/O
Max response frequency up to 50Kpps

Applications
It is suitable for a variety of small-scale automation equipments and instruments, such as 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.
