what does it mean when my spindle VFD inverter shows OC-2?

Remember, steps to correct and troubleshoot issues with any electrical devices should be done by a professional electrician. If you have an HY series VFD, the fault codes are below: OC-1: Over-current during ramp up or over-current at constant speed. Recommended actions: 1, 2, 3, 4 OC-1: Over-current during ramp up or over-current at constant speed. Recommended actions: 1, 2, 5, 6 OC-2: Over-current at deceleration or over-current at stop. Recommended actions: 1, 7, 2, 9, 10 dL: Output short circuit. Recommended actions: 11, 1, 10 Ou-1 or 2: Over-voltage at stop, over-voltage at acceleration, over-voltage at constant speed or over-voltage at deceleration Recommended actions: 12, 13 Fb: Fuse break. Recommended actions: 14, 10 Lu: Low voltage. Recommended actions: 15, 16, 17 OH: Over heat of inverter. Recommended actions: 18, 19, 20 OL-1: Inverter overload 150% per minute Recommended actions: 2, 21, 22 OL-2: Motor overload 150% per minute. Recommended actions: 21, 23, 24, 25, 26, 21 dT: Motor over-torque Recommended actions: 21, 23 E.b.S.A or E.b.S.n or E.b.S.d or E.b.S.S: No feedback from the auxiliary coil or the lectromagnetic contactor Recommended action: 27 bt: Braking transistor damage. Recommended action: 27 CPu: CPU fault. Recommended action: 27 E.E.E.S or E.E.E.n or E.E.E.d or E.E.E.A: EEPROM fault Recommended action: 27 List of recommended actions: If error shows at ramp up or at constant speed: 1. Check for a short circuit or partial short circuit and the insulation of the output wire is sufficient. 2. Increase the capacity or the inverter if it is too small. Replace with an inverter that has a larger capacity 3. Extend the ramp-up time 4. Decrease the torque and increase the set value. 5. Check if the motor is blocked and if there is a sudden change in load. 6. Check if there is a sudden chance in the power supply voltage. 7. Extend ramp down time 9. DC breaking is too high. Decrease DC breaking 10. Replace the inverter. 11. Check to see if there is a short circuit with the connection wire of the motor. 12. Extend the ramp-down time or add a breaking resistor. 13. Check the mains supply voltage and insure there isn't ant sudden change in voltage. 14. Send the inverter for repair. 15. Check whether the input voltage is normal 16. check whether there is a sudden change in load. 17. Check whether there is any phase missing. 18. Check the fan in the inverter. Is it spinning? Is it blocked? Does it have any foreign matter stuck on the fins of the fan? If so, clear the fan. 19. Check the ambient temperature in the space that the inverter is placed. 20. Check for adequate ventilation for the inverter where it is placed. 21. Check for jamming or any sudden change with respect to mechanical load. 22. Set the V/F curve correctly. 23. The motor is too small. 24. The motor is hot and the insulation of the motor degraded. 25. Check if the voltage has a large variance. 26. Check if there is a phase missing. 27.
