The Advanced Drive TM5‑015i‑1N (AD‑22395‑C‑A‑2.00) is a single‑phase input, three‑phase variable frequency drive designed for Cybex high‑performance treadmills, delivering 6–9 A output up to 150 Hz. Common failure points in this class include phase loss or over‑current on the output windings, insulation breakdown between stator and rotor, and degradation of the internal power MOSFETs or IGBT modules due to thermal cycling. Begin diagnostics by verifying the 100–115 V input supply and inspecting for proper grounding; check the output current and voltage waveforms with a multimeter/oscilloscope for phase balance and clipping; then examine the drive’s printed circuit board for burnt components, loose solder joints, or cracked heat‑sinking pads.[oss-gpt-20b]
