Yaskawa CIMR-P5M47P5 power supply

The Yaskawa CIMR‑P5M47P5 is a 3‑phase variable frequency drive rated at 15 HP with an input range of 380–460 V AC and a frequency range up to 400 Hz. Common failure modes for this model include power‑supply capacitor degradation, insulation breakdown in the inverter windings, and overheating of the internal SMPS components due to inadequate ventilation or over‑current conditions. Begin troubleshooting by verifying that the incoming line voltage is within spec, measuring output DC bus voltage and ripple on the SMPS, inspecting all capacitors for bulging or leakage, and checking the drive’s diagnostic LEDs or fault codes for indications of insulation or thermal faults.[oss-gpt-20b]
