Welcome to wantaimotor store
This item includes:
4 PCS Stepper Driver with 7.8A replacing MD882,
1PC Breakout Board for free offering
The Breakout Board is offered to you for free to buy this item above, so that you can set this kit up, and work in better condition.
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.
Low cost and good high-speed torque
14 selectable resolutions
Supply voltage up to +80VD
Suitable for-2-phase and 4-phase motors
Output current up to 7.8A,5.86A rated current, 256Microstep
Dip switch current setting 8different values
Optically isolated input signals
Pulse frequency up to 200KHz
Automatic idle-current reductiOn
Small size (107*97*48),Weight:0.3KGS
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 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.
Enable signal:This signal is used for enabling/disabling the driver.High level for enabling the driver and low level for disabling the driver.
Usually left unconnected (enabled)
