Description
This item includes:
1 PC Stepper Driver with 7.8A/80VDC/256Microstep, DQ860MA,
1, Introduction
The DQ860MA is an economical microstepping driver based on patented technology of Wantai Motor .It is suitable for driving 2-phase 4-phase hybrid stepping motors .By using the advanced bipolar constant-current shopping technique ,it can output more speed and torque from the same motor,compared with traditional drivers ,such as L/R drivers .Its 3-state current control technology allows coil currents to be well controlled and with relatively small current ripple,therefore less motor heating is achieved.

Details |
PUL+,PUL- |
Pulse signal:In single pulse (pulse/direction)mode,this input represents pulse signal,effective for each rising or falling edge;4-5V when PUL-HIGH,0-0.5V when PUL-LOW.For reliable response ,pulse width should be longer than 5µs.Series connect resistors for current limiting when +12V or +24V used. |
DIR+,DIR- |
DIR signal:In pulse mode,this signal has low/high voltage levels,representing two directions of motor rotation;For reliable motion response,DIR signal should be ahead of PUL signal by 5µs at least.4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. |
ENA+ |
Enable signal:This signal is used for enabling/disabling the driver.High level for enabling the driver and low level for disabling the driver. |
