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

Current Solution

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

Recommended actions: 15, 16, 17

OH: Over heat of inverter.
Recommended actions: 18, 19, 20

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. Contact the supplier

Other Possible Solutions to this Question

  • My VFD/inverter is showing an er.04 er 04 on the display when the spindle starts spinning

    The Er.04 (if you are using the YL VFD), generally refers to the ramping up and ramping down of the spindle, but it can be a result of a short circuit between the VFD and the spindle. You can increase the time the spindle accelerates (ramps up to the set rpm/frequency).

  • WHAT ELECTRICAL CABLE DO I USE TO CONNECT VFD INVERTER SPINDLE?

    The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

    The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

    Currently we use 20AWG 4 conductor.

  • When using the laser controller, what does "engrave beyond border limit" mean?

    LaserCAD: Engrave beyond border limit.

    This is caused by a sweeping motion that is too fast and where the acceleration is too slow. My recommended action would be to keep the acceleration the way it is and slow down the speed of the engrave sweeping motion. I typically use around 200-300 mm/sec and make sure that the axis sweep motion is the nozzle along the gantry, not the gantry itself. The gantry will have too much inertia to sweep, but the nozzle is very light and can sweep very quickly.

    Specifically, what is happening with the engrave beyond border limit is where that axis is not able to slow down fast enough to not hit the border. For instance, imagine a car going 100 mph and it needs to stop within 30 feet. This would not be possible because the deceleration is not high enough.

  • I would like to know what the lowest rpm that can be acheived with the 2.2kw spindle and inverter and still have enough torque to drill

    According to the supplier of the 2.2 kW spindle, the safest operating speed for the spindle is 6000 RPM. The supplier also stated that theoretically, the spindle can operate from 0 to 24,000 RPM. I am continuing a dialog with the supplier to delve deeper into understanding the configurations and ramifications of such configurations for operations outside of the safe boundaries into the "theoretical" ranges.

  • please send wiring diagram for the 1500kw spindle and inverter combo. i need to see what additional things need be purchased. thanks.

    Please refer to the Spindle wiring diagram found on the product page for the 2.2KW spindle. The wiring diagram will be the same for the 1.5kW Spindle. The only difference will depend on if you are using 110v or 220v power, as setting PD008 asks you to specify the max voltage.

  • Is a 110v 20a circuit sufficient to run the spindle (2.2kw w/110v inverter)?

    t might be a better idea to increase the circuit breaker above 20 as 2200/110 is exactly 20. You will not have a buffer there in case you need it. Alternatively, you can decrease the current draw of the spindle in the VFD programming process.
