DM860A 2-Phase Stepper Motor Driver

The DM860A is a new generation high-performance digital stepper driver based on DSP and PID control algorithm with microstep control technology. The motors driven by DM860A can run with much smaller noise and much less vibration than other drivers in the market. The DM860A possess the feature of lower noise, lower vibration, and lower heating. The DM860A’s voltage is AC20V-80V(DC36-110V). It is suitable for all the 2-phase hybrid stepper motor whose current is less than 6.0A. There are 16 kinds of microstep of DM860A. The maximum step number of DM860A is 51200 steps/rev (microstep is 1/256 ). Its current range2.0A-6.0A, and its output current has 8 stalls.DM860A has automatic semi-flow, over-voltage, under voltage and over-current protection function.

Features

• Adoption of 32-bit DSP, pure sine wave subdivision technology
• Low-noise, low-vibration and low temperature rising
• Voltage 24-80VAC
• With 8 stalls output current setting, current range 2.4A - 7.2A
• With 16 stalls microstep subdivision setting
• Automatic half current, self-test, over voltage, under voltage, over current protection
• Internal optical isolation, highest frequency response 200KHZ
