Introduction:
DM860A is a type of two-phase hybrid stepping motor driver, The drive voltage of which
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. This circuit that it
adopts is similar to the circuit of servo control which enables the motor run smoothly almost
without noise and vibration. Hording torque when DM860A run under high speed is also
significantly higher than the other two-phase driver, 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.
Features:
High performance, low price
Average current control, 2-phase sinusoidal output current drive
Supply voltage from 24VDC to 80VDC
Opto-isolated signal I/O
Overvoltage, under voltage, overcorrect, phase short circuit protection
14 channels subdivision and automatic idle-current reduction
8 channels output phase current setting
Offline command input terminal
Motor torque is related with speed, but not related with step/revolution
High start speed
High hording torque under high speed

When the high electrical level is active, all control negative signals will be connected together to GND. When low electrical level is active, all control positive signals will be connected together to public port.
