DM860 / DM860H / DQ860MA 2-phase Stepper motor driver 7.8A, 24-80V 256micsteps

Introduction:

• DM860 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
