Stepper Wiring Question
May 13, 2008 10:10PM
I've connected my motor to the driver board and it's smoothly twisting while running the test script that accompanies the instructions. The direction pin starts out high in the script, and that corresponds to either clockwise or counterclockwise, depending on how I wire the motor to the board. If I were using the recommended motors wired in the standard way, which direction should the motor turn when the dir pin is high?

Also, I ran without a heatsink for about 5 minutes and the L298 got hot enough to burn me.

Thanks.

i believe that the motor should turn clockwise if you wire them correctly.

however, if you're using the arduino system, its as simple as reversing the connector to have the motor rotate in the opposite direction.

Ah, I hadn't fit the connector yet because I hadn't decided which wire went to which pin. Thanks, Zach!

Just in case anybody else ends up using the same motors, here's the motor info and wiring configuration:

Step-Syn
Stepping Motor
Type 103-714-1241
DC 3.27 V
2.85 A
1.8 Deg/Step
Sanyo Denko Co. Ltd.
6 wires.

If you're holding the board so you can read the copyright notice, the motor connector is on your right, at the edge of the board. The pins, from top to bottom should connect to the wires colored blue, orange, red, yellow. Leave black and white unconnected. In that configuration, all appears to work properly.
