3PCS Stepper Driver with 24-80V 7.8A DQ860MA digital serial,
1 PC Breakout Board & 1 Cable forfree
1, Stepper Motor Driver
DQ860MA is a typeof two-phase hybrid stepping motor driver, the drive voltage ofit 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 7.8A 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. Holding torque when DQ860MA 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:
²High performance, low price
²Average current control, 2-phase sinusoidal output current drive
²Supply voltage from 24VDC to 80VDC
²Opto-isolated signal I/O
²Overvoltage, under voltage, overcurrent, phase short circuit protectio
²14 channels subdivision and automatic idle-current reduction
²8 channels output phase current setting
²Offline command input terminal
²Motor torque is related to speed, but not related to step/revolution
²High start speed
²High hording torque under high speed

Pin Function
Details
PUL +,PUL-
Pulse signal, PUL+ is the positive end of pulses input pin
PUL- is the negative end of pulse input pin
DIR+,DIR-
DIR signal: DIR+ is the positive end of direction input pin
DIR- is the negative end of direction input pin
ENBL+
Enable signal: ENBL+ is the positive end of direction input pin. This signal is used for enabling/disabling the driver. High level for enabling the driver and low level for disabling the driver.
ENBL-
ENBL- is the negative end of direction input pin. Usually left unconnected (enabled)
Function choice ( Using DIP pins to achieve this function)
1) Micro step resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table:

2) Standstill current setting
SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current and ON meaning that standstill is set to be the same as the selected dynamic current.
3) Output current setting:
The first three bits (SW 1, 2, 3)of the DIP switch are used to set the dynamic current. Select a setting

4) Semi-flow function:
Semi-flow function is that there is not step pulse after200 ms, the driver output current automatically reduced to 40% of rated output current, which is used to prevent motor heat.
