What to do if my Powtran Inverter displays Err.02?
- CChristopher HarrisNov 21, 2025
If the Powtran Inverter shows Err.02, it could be due to several reasons: * The acceleration time might be too short, in which case you should increase it. * The manual torque boost or V/F curve might be unsuitable, so adjust them. * Low voltage can cause this, so set the voltage to the normal range. * A short-circuit or earthing of the inverter output requires you to eliminate peripheral faults. * If using vector control mode without parameter identification, perform identification for the motor parameters. * If the motor starts unexpectedly while rotating, select Speed Tracking Start or restart after stopping the motor. * A sudden increase in load during acceleration may trigger this, so cancel the sudden load. * If the inverter type is too small, choose one with a large...
