2-Phase Stepping Motor Driver CF2068H

Overview

CF2068H is a 2-phase hybrid stepping motor driver   based on DSP control. It is a new generation of digital stepping motor drive   which combines advanced DSP control chip and 2-phase inverter drive module. The   drive’s voltage is between AC18V-80V, adapter current is below 7.2A and 57-110MM diameter of all kinds of 2-phase   hybrid stepping motors. It uses a similar servo control circuit, which can   make the motor running smoothly, almost no vibration and noise. When the   motor is at high speed, its torque is much higher than other hybrid stepping motors.   Positioning accuracy is up to 40,000 steps / turn. The product is widely used   in engraving machine, medium-sized CNC machine tools, computer embroidery   machine, packaging machinery and other high resolution, large and   medium-sized CNC equipment.

Key Features

·           High performance   and low price

·           Equipped with 16   scales constant torque moment subdivision, the maximum resolution is 40,000   steps / turn

·           The maximum response   frequency is up to 200KPPS

·           When a stepping   pulse stops more than 1.5S, the coil current will be automatically reduced to   half of the set current

·           Optical isolation   signal input / output

·           Drive current 2.0A   / phase to 6.0A / phase 16 scales adjustable

·           Single power   input, voltage range: AC18-80V

·           The phase memory   function (Note: When the drive stops for more than 3 seconds, it will   automatically memorize the motor phase then re-energizes. When the WF signal   goes from low to high, the drive will automatically recover the motor phase.)

Current   Setting

The operating current of the drive is set by the SW1-3 terminals, which   switch for normal working output current (See the table below).
