    What to do if my TECO L510 shows an OV Over voltage error?

      Tracy CrosbyJul 27, 2025
      If your TECO Inverter displays an OV Over voltage error, it could be due to several reasons. One common cause is that the deceleration time is set too short, leading to regenerative energy flowing back from the motor. In this case, you should increase the deceleration time. Also, check if the inverter input voltage is too high; if so, reduce it to meet the required levels or install an AC line reactor. The issue might also arise from the use of power factor correction capacitors, which should be removed. For excessive braking load, consider using a dynamic braking unit. Furthermore, a defective braking transistor or resistor could be the culprit, necessitating replacement. Finally, incorrect speed search parameters can also trigger this error, so adjust them accordingly.

      If your TECO Inverter is showing an OV Over voltage error, it might be because the input voltage is too high. To resolve this, reduce the input voltage to comply with the input voltage requirements, or consider installing an AC line reactor to lower the input voltage.
