Introduction:
DQ860HA is a type of two-phase hybrid stepping motor driver, the drive voltage of it 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:
² High performance, low price
² Average current control, 2-phase sinusoidal output current drive
² Supply voltage from 24VDC to 110VDC 24VAC-80VAC
² Opto-isolated signal I/O
² Overvoltage, under voltage, overcurrent, phase short circuit protectio
² 14 channels subdivision and automatic idle-current reduction
² 8 channels output phase current setting
² Offline command input terminal
² Motor torque is related to speed, but not related to step/revolution
² High start speed
² High hording torque under high speed

Pins assignments and description:
Connector Pins Configurations
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:
SW5 | ON | OFF | ON | OFF | ON | OFF | ON | OFF | ON | OFF | ON | OFF | ON | OFF |
SW6 | ON | ON | OFF | OFF | ON | ON | OFF | OFF | ON | ON | OFF | OFF | ON | ON |
SW7 | ON | ON | ON | ON | OFF | OFF | OFF | OFF | ON | ON | ON | ON | OFF | OFF |
SW8 | ON | ON | ON | ON | ON | ON | ON | ON | OFF | OFF | OFF | OFF | OFF | OFF |
PULSE/REV | 400 | 800 | 1600 | 3200 | 6400 | 12800 | 25600 | 51200 | 1000 | 2000 | 5000 | 10000 | 25000 | 50000 |
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
Closest to your motor’s required current
Output current (A) | ||||
SW1 | SW2 | SW3 | PEAK | RMS |
ON | ON | ON | 2.80 | 2.00 |
OFF | ON | ON | 3.50 | 2.50 |
ON | OFF | ON | 4.20 | 3.00 |
OFF | OFF | ON | 4.90 | 3.50 |
ON | ON | OFF | 5.70 | 4.00 |
OFF | ON | OFF | 6.40 | 4.60 |
ON | OFF | OFF | 7.00 | 5.00 |
OFF | OFF | OFF | 7.80 | 5.60 |
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.
