Why does my Savch Inverter show over current when accelerating?
- P
  Patricia WalkerAug 13, 2025
  If your Savch Inverter is showing an over current error during acceleration, it could be due to several reasons. First, the acceleration time might be too short, so try increasing it. Second, the electricity grid voltage might be too low, so check the input power supply. Finally, the inverter power might be insufficient for the load, in which case you should choose an inverter with higher power.

What to do if Savch Inverter shows over current when decelerating?
- P
  Patrick BrownAug 17, 2025
  If you're experiencing an over current error during deceleration with your Savch Inverter, consider these potential causes. It might be that the deceleration time is too short, so try increasing it. Another possibility is that the load inertia torque is large; in this case, add a proper braking component for power consumption. Lastly, the inverter power might be too low, so consider choosing an inverter with higher power.

  Ryan NealAug 21, 2025
  If your Savch Inverter shows an over voltage error during acceleration, it could be due to the following reasons: the input voltage may be abnormal, so check the input power supply. Alternatively, the motor might be restarting while still rotating after a power interruption; avoid restarting the motor immediately after stopping.

  Erica MillerAug 26, 2025
  If your Savch Inverter is showing an over voltage error during deceleration, there are several possible causes. The deceleration time might be too short, so try increasing it. Additionally, the load inertia could be large, so increase the braking component for power consumption. Finally, the input voltage might be abnormal, so check the input power supply.

What to do if Savch S2800 keeps over current at constant speed?
- T
  Tyler LopezAug 28, 2025
  If your Savch Inverter maintains an over current at a constant speed, it could be due to a load mutation or abnormality, so check the load or decrease load mutation. It may also be that the motor is starting again while still rotating after an interruption in the power supply, so check the input power supply. Finally, it may be necessary to choose an inverter with higher power.

  Jennifer CortezSep 1, 2025
  If your Savch Inverter maintains an over voltage at a constant speed, it might be due to an unusual change in the input voltage, so install an input reactor. Another possibility is that the load inertia is large, so add a proper braking component for power consumption.

How to fix conversion unit U-phase failure in Savch Inverter?
- R
  Randall BrownSep 5, 2025
  A conversion unit U-phase failure in your Savch Inverter can stem from several causes. It could be due to excessive acceleration, so increase the acceleration time. Interference might be causing incorrect action, so check the peripheral equipment for interference sources. Poor grounding may also be a factor.

What causes busbar under voltage in a Savch S2800 Inverter?
- S
  Steven CochranSep 8, 2025
  If your Savch Inverter is showing a busbar under voltage error, it's likely that the electricity grid voltage is too low. Check the power supply of electricity grid input to resolve this issue.
