USING THE EVALUATION BOARD
EQUIPMENT REQUIRED · Two-phase stepper motor · Voltage supply to power the stepper motor SETUP 1. Set the motor voltage supply to the intended voltage. 2. Tum off motor voltage supply. 3. Connect motor voltage supply to J1. 4. Connect the stepper motor to J2. One winding connects to J2
pins 1 and 2. The second winding connects to J2 pins 3 and 4. Note: Do not connect or disconnect the motor unless the outputs are either disabled or the VBB voltage is off. 5. Turn the voltage supply on. 6. If the stepper motor is not spinning, check the following: A. Ensure that POTl is adjusted to provide an appropriate
Step input frequency for the stepper motor; B. Ensure that the logic inputs are in the proper states; C. Ensure that JMPl shunt is installed; D. Ensure that P1 is adjusted to provide a VREF voltage that
results in the proper peak output current.
