- If a fault occurs, do not attempt self-repair; contact TECORP GROUP or distributors.
Scrapping Processing:
- Warning:
- Dispose of scrapped AC motor speed controllers as industrial rubbish; do not burn them.
Fault Alarm and Solution:
The manual provides a comprehensive table of error codes, possible reasons, and solutions:
- OC-1 (Over Current in Acceleration): Too short acceleration time, disarrangement of V/F curve, restart in running motor, unsuitable capacity, disarrangement of controller. Solutions: Extend acceleration time, correct V/F curve, restart motor, select suitable motor, check connection.
- OC-2 (Over Current in Deceleration): Too short deceleration time, bigger potential load/loading inertia, less capacity, disarrangement of controller. Solutions: Extend deceleration time, add braking resistors, select suitable motor, check connection.
- OC (Over Current in Constant Speed): Too low voltage, less capacity, restart in running motor, too heavy load. Solutions: Check input power, check phrase, select suitable motor, restart motor, check connection.
- OE-1 (Over Voltage in Running): Abnormal input voltage, restart in running motor. Solutions: Check input power, restart motor.
- OE-2 (Over Voltage in Deceleration): Too short deceleration time, bigger potential load/loading inertia, abnormal voltage. Solutions: Extend deceleration time, add braking resistors, check input power.
- OE (Over Voltage in Constant Speed): Abnormal input voltage. Solutions: Install input voltage, check input voltage.
- ELT (Failed to the Capacity Module): Sudden over current, short circuit of output or grounding, bad aeration/failed fan, failed capacity bridge. Solutions: Refer to OC, check connection/wire, improve aeration/replace fan.
- OH (Over Heat in Capacity Module): Beyond requirement, bad aeration/failed fan, failed detective circuit of temperature. Solutions: Improve environment, improve aeration/replace fan.
- OL (Over load of Motor): Disarrangement of V/F curve, too low voltage, run with low speed/high torque for long time, improper loading coefficient, motor blocked/too high torque. Solutions: Correct V/F curve, check input power, select specialized inverter, check set parameters, select suitable motor, check connection.
- EMS (Failed to the External): Failed to terminals of external equipment. Solution: Check terminals.
- CPUE (Magnetic disturbance): Taking serious disturbance. Solution: Push STOP/RESET button.
- -.E.r (Failed to EPROM): Taking serious disturbance of EPROM in reading/writing, failed EPROM. Solution: Push STOP/RESET button.
