Verify that input power is on L1/L2/L3 and the motor is on U/V/W.
Critical for overload protection; copy exact nameplate Amps. 4. Troubleshooting and Fault Codes Convo Inverter Cvf-s1 Manual
The official manual's "Simple Operation" process provides a step-by-step guide: Verify that input power is on L1/L2/L3 and
| Error Code | Error Type | Probable Cause | Recommended Action(s) | | :--- | :--- | :--- | :--- | | | Over-current during Acceleration | Acceleration time too short; Torque boost too high. | 1. Extend L-1 (Accel Time). 2. Lower torque boost voltage. | | Er.02 | Over-current during Deceleration | Deceleration time too short. | Increase the deceleration time parameter ( L-2 ). | | Er.05 | Over-voltage during Deceleration | Deceleration time too short; Power supply anomaly. | 1. Extend L-2 (Decel Time). 2. Check incoming power. 3. Install brake resistor. | | Er.09 | Inverter Overload | Load on motor is too heavy; Acceleration time too short. | 1. Reduce the mechanical load. 2. Increase L-1 (Accel Time). | | Er.11 | Inverter Over-temperature | Airflow blocked; Ambient temperature too high; Fan broken. | 1. Clean cooling fan and vents. 2. Lower carrier frequency. 3. Replace fan. | | Er.14 | Output Phase Loss | Loose or broken connection between inverter and motor. | Disconnect power and check the integrity of all motor wiring connections. | | Er.15 | IPM Fault | Output short circuit or ground fault; Power module damaged. | 1. Check all output wiring. 2. If no external problem exists, contact manufacturer. | Power module damaged. | 1.
