At5-1500x 110v single phase input to 220v 3phase output model. Cannot change parameters. Can't unlock the password. Is there a hard reset configuration or what can I do to fix this issue??

To unlock the password and change parameters on the XSY AT Series AT5-1500X, follow these steps:

1. Locate Parameter P08: This is the hidden password parameter. It always displays as "00000" and does not show the actual stored value.

2. Enter the Password Using P09:
- Set parameter P09 to the hidden value of P08 (you must know the correct password value).
- If correct, P08 will then reveal the hidden value, and parameter changes will be allowed.

3. Change Parameters: Once unlocked, you can modify P08 and other parameters.

4. Power Cycle Effect:
- If you unplug the power cable and restart, P09 will be cleared.
- You would need to re-enter the correct value into P09 again to unlock parameters.

A hard reset method is not described. If the password is unknown, there is no documented way to bypass or reset it without the correct value.

@Mr. Anderson thank you for the input. I've tried all the above but cannot get it to unlock. I'm going to try some more but if not able to change the parameters. Possibly buy another vfd

Error 2 on the XSY AT Series indicates an "Undervoltage protection" fault. To fix this issue:

1. Check the power supply voltage to ensure it meets the required specifications.
2. Inspect wiring connections for loose or damaged cables.
3. Verify that the power input terminals are properly connected.
4. If the voltage is too low, consider using a stable power source or voltage regulator.
5. Restart the inverter after correcting any voltage issues.

If the problem persists, further troubleshooting or professional assistance may be needed.

To reset Error 2 (Undervoltage protection) on the XSY AT Series:

1. Identify and fix the cause of undervoltage—ensure the input voltage meets the required specifications (e.g., 220V AC for AT1 and AT2, 380V AC for AT3).
2. After resolving the voltage issue, use the error reset signal:
- Assign function 8 (error reset signal) to one of the multifunction input terminals (e.g., P50 to P55).
- Activate the corresponding input (e.g., by shorting the assigned port with COM).

This will reset the error and resume normal operation.

Low voltage protection in the XSY AT Series is indicated by the fault code "Err 2" and is referred to as "Undervoltage protection." This function protects the inverter by triggering a fault when the input voltage drops below a safe operating level.

I've got a "bj301" message on the display, It doesn't allow me to modify anything...Is there any key combinación to bypass this message?

quali sono i terminali della morsettiera da collegare per avere la funzione di start e stop esterna al pannello di controllo e quale è il parametro relativo da modificare

For external start and stop functions on the XSY AT Series terminal block:

- Use a normally open (NO) momentary push button connected between COM and terminal P2 for the start function. This is controlled by PARAM 3.
- Use another NO momentary push button between COM and the appropriate terminal (typically specified for stop control) for the stop function. This is controlled by PARAM 4.

PARAM 3 enables motor run when the start button is pressed, and PARAM 4 stops the motor when the stop button is pressed.

Error 8 on the XSY AT Series indicates "Excessive temperatures for radiator." To fix this error:

1. Check if the cooling fan is working properly.
2. Ensure the radiator is clean and not blocked by dust or debris.
3. Improve ventilation around the inverter.
4. Reduce the load or allow the inverter to cool down before restarting.

After resolving the issue, restart the inverter to clear the error.
