9. Troubleshooting
R325P is not functioning correctly
Try putting the R325P into TEST mode by placing a jumper on Pins 3 & 4 of J1 as shown below. The motor
should twitch back and forth slightly if the R325P is functioning properly.
R325P not moving the motor (Step/Dip)
Verify that the 5V is being supplied to Pin 1.
The R325P is causing the motor to vibrate and jitter back and forth
Are the Motor phases switched? Be sure to check that motor wires are connected to Pins 6 through 9, in the
order of A, A Bar, B, B Bar. To check which wires belong to one phase, take a Meter to measure resistance
between any two wires. If there is a finite value between two of them, insert the wires into pins 6 and 7, OR
pins 8 and 9. Insert the remaining two wires accordingly.
