The DM860A is a type of two-phase hybrid stepping motor driver for one motor. The drive voltage is from 24VDC to 80VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 57mm to 110mm outside diameter and less than 8.0A phase current.
Inputs and Outputs are opto-isolated.
Overvoltage, under voltage, overcorrect, phase short circuit protection
14 channels subdivision and automatic idle-current reduction. 8 channels output phase current setting
Holding torque when the DM860A is run under high speed is also significantly higher than other two-phase drivers, what’s more, the positioning accuracy is also higher.
It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on.
