Speed Calibration: PWM PCB Motor Control Treadmills
1. Enter diagnostic mode as outlined in “Entering Diagnostic Mode Procedures” on page
41 as appropriate for
your control.
2. Adjust the max speed first. Bring the set speed to 12mph. Let actual speed stabilize.
3. Adjust the MAX potentiometer on the PWM motor control board accordingly.
• Clockwise: increases speed
• Counterclockwise: decreases speed
4. Decrease set speed to 0.5mph. Let actual speed stabilize. Adjust the MIN pot accordingly.
Note:
0.48 to.52 mph is acceptable.
5. Before turning treadmill off, check the MAX speed one more time for accuracy.

PWM Motor Control Board IR COMP Potentiometer Adjustment
If the PWM motor control board IR COMP potentiometer is out of adjustment then stepping onto the treadbelt will
result in either a surge in treadbelt speed or make it feel like it’s pulsing. To adjust the IR COMP potentiometer:
No load / belt surging / LED1 flashing:
Use a small screwdriver to rotate IR COMP potentiometer. Make this
adjustment while the treadmill is running (surging). Rotate the pot in small increments until the treadmill surge
subsides and runs smoothly.
Note:
The IR COMP potentiometer can be rotated clockwise (CW) or counterclockwise (CCW) to achieve smooth operation.
With load / belt surging / LED1 may be flashing:
Use a small screwdriver to rotate IR COMP pot. Make this
adjustment while the user is walking on the treadmill. Rotate the pot in small increments until the treadmill surge
subsides and runs smoothly. Keep speed setting under 2.0mph for safety.
