Treadmill Tops Out at 6 mph Only
Answer: Current-limit circuitry is choking output often a bad shunt resistor. UpFix recalibrates and verifies full rated speed under load.
Quick take: Current‑limit circuitry thinks the motor’s pulling too many amps and throttles output.
Checks
-
Lubricate belt to reduce drag.
-
If speed still caps, the shunt resistor or sense amplifier on the MCB is off‑spec.
UpFix methodology
-
Replace shunt resistor with precision 1 % part
-
Re‑calibrate current loop in firmware (if accessible)
-
Confirm max speed on load dyno
