What does PO Voltage Off mean on my TECO Inverter and how to fix it?
- TTimothy ChavezSep 14, 2025
If your TECO Inverter is showing a PO Voltage Off error, check the SF1 and SG connection.
What does PO Voltage Off mean on my TECO Inverter and how to fix it?
If your TECO Inverter is showing a PO Voltage Off error, check the SF1 and SG connection.
What should I do if my TECO E510s displays OCA over current?
If you're seeing an OCA over current error on your TECO Inverter, try these steps: Set a longer acceleration time. If that doesn't work, consider changing to an inverter with a bigger capacity. Examine the motor and check the wiring. As a last resort, replace the IGBT module.
What does OV Over voltage mean on my TECO Inverter and how to fix it?
If your TECO Inverter is showing an OV Over voltage error, here are some possible solutions: Increase the deceleration time. Reduce the input voltage to comply with the input voltage requirements, or install an AC line reactor to lower the input voltage. Remove the power factor correction capacitor. You could also use a dynamic braking unit, replace the braking transistor or resistor, or adjust the speed search parameters.
What should I do if my TECO E510s displays OCC over current?
If your TECO Inverter shows an OCC over current error, here are a few things you can try: Set a longer acceleration time. Consider changing to an inverter with a bigger capacity. Examine the motor and check the wire. If necessary, replace the IGBT module.
Why does my TECO E510s Inverter show GF Ground fault, and how can I fix it?
If your TECO Inverter is displaying a GF Ground fault error, consider these steps: Replace the motor. Check the motor wiring. Disconnect the motor and try running the inverter. Check the resistance between cables and ground. Reduce the carrier frequency.
What does LPBFT Low Pressure Fault mean on my TECO E510s and how to fix it?
If your TECO Inverter displays a LPBFT Low Pressure Fault, you can try the following: Check if the feedback signal is correct and with the proper connection. Check if the feedback value of pressure is lower than the limit of minimum pressure (23-15).
What to do if my TECO Inverter displays FBLSS PID Feedback Signal Loss?
If your TECO Inverter displays FBLSS PID Feedback Signal Loss, you can try the following: Check if the proportion of loss pressure (23-19) is set correctly. Make sure the feedback sensor is installed correctly and the PID feedback signal operates normally.
What does OPBFT High Pressure Fault mean on my TECO Inverter and how to fix it?
If your TECO Inverter displays an OPBFT High Pressure Fault, you can try the following: Check if the feedback signal is correct and with the proper connection. Check if the feedback value of pressure is lower than the limit of minimum pressure (23-12).
