What causes Err.03 on a Powtran PI500-S 022G3 and how to fix it?
- AAshley WellsAug 26, 2025
The Err.03 error on your Powtran Inverter can arise from several factors. Here's what to check: * A short-circuit or earthing of the inverter output. If this is the case, eliminate peripheral faults. * If you're using vector control without identifying parameters, perform motor parameter identification. * A deceleration time that's too short. Increase the deceleration time. * Low voltage can cause this error. Set the voltage to the normal range. * If the load suddenly increases during deceleration, cancel the sudden load. * Lack of a braking unit and braking resistor. Install a braking unit and brake resistor.
