JK 1545 step motor driver

This step motor driver is used in the jointmaster finger joint jig together with this step motor and this power supply.

This is the best step motor driver in the universe. You pay some extra money and your Jointmaster is ultra-reliable. You are the Joint Master.
Never no failure, relax and finger joint automatically. You make love while the Jointmaster continues fingerjointing. Gives you more time to ponder your “mental health”

1、 VCC+：DC power positive pole Note:Must guard against exceeding 50V, so as not to damage the module

2、GND：DC power cathode

3、A+、A-：Stepping motor one winding

4、B+、B-：Stepping motor other winding

5、PUL+、PUL -：Stepping pulse input+5V (Rising edge effective ,         rising edge duration >10μS)

6、DIR +、DIR-：Stepping motor direction input, voltage level touched off,high towards, low reverse

7、ENA+、ENA-: motor free          

WARNING: ALL IO Ports must be filtered from excessive EMI. Read the post “EMI and Reliability”  For this reason you need 12 ferrite beads and electronic enclosure.

1: When ambient temperature is high or working current is over 2.7A,  use a fan to dispel the heat to make the module run reliably for a long time.

2: Half current is set automatically: If the control machine does not send out a pulse signal  for half a second, the step motor driver enters half current state automatically for electricity saving.

3: The phase current inside the electric phase winding is protected : When the step motor phases are connected to the driver , users could connect the phases in a wrong way. The protection circuit inside the driver protects the driver against serious damage. The driver will not be damaged, but the electrical machinery runs abnormally, shakes, and torque output is small. In that case check whether the wiring of electrical machinery is wrong.

Switch Choice: (“ON=0，OFF=1”)                                                      

3、Full current or half current choice：SW4：0＝Full current；1＝half current

4、Pulse choice：Inside the driver is a jumper to set pulse
