How to fix over-current during acceleration (Acc process) in Santerno SINUS VEGA 2S Inverter?
- R
  rebekah43Aug 21, 2025
  If your Santerno Inverter displays an over-current error during acceleration, it could be due to several reasons. It may be caused by an acceleration time that is too short, so try prolonging the acceleration time. The V/F curve might not be suitable, so check and adjust the V/F curve, adjust torque boost, or correctly set the motor parameters to ensure the auto torque boost works well. Also, check the inverter’s input AC supply, as a low AC supply voltage can cause this issue. If the moment of inertia of the load is too large, reduce the load and prolong the acceleration time. Ensure the motor completely stops before restarting the inverter. Verify that the motor parameters are properly set and that the inverter power is adequate; if not, select a higher power inverter.

What to do if Santerno Inverter shows over-current in Dec process?
- J
  Jonathan ButlerAug 23, 2025
  If a Santerno Inverter shows an over-current error during deceleration, it could be due to a deceleration time that is too short, so prolong the deceleration time. It may also be caused by a load inertia that is too high, so connect a suitable braking device. Finally, the inverter’s power may be too low, so select an inverter with a larger capacity.

Why is my Santerno Inverter showing over voltage in Dec process?
- T
  Teresa RodriguezAug 25, 2025
  If a Santerno Inverter shows an overvoltage error during deceleration, it could be because the deceleration time is too short relative to the energy being generated, so prolong the deceleration time. It may also be because the load inertia is too high, so use a suitable dynamic braking device.

What causes Santerno SINUS VEGA 2S overload and how to resolve it?
- J
  Joseph RobinsonAug 27, 2025
  If your Santerno Inverter is experiencing an overload, it could be due to several factors. The acceleration time might be too short, so try prolonging it. Excessive DC braking energy could be the cause, so reduce the DC braking current and prolong the braking time. An improper V/F curve can also lead to overload, so adjust the V/F curve or torque boost value. Avoid restarting the inverter while the motor is still rotating; ensure the motor stops completely before restarting. Check the AC supply voltage, as a low voltage can cause an overload. Finally, the load might be too heavy for the inverter, so consider selecting an inverter with larger power.

Why does my Santerno SINUS VEGA 2S show over-current during constant speed operation?
- B
  Brian WrightAug 28, 2025
  If your Santerno Inverter displays an over-current error during constant speed operation, it might be due to a sudden change in load, so reduce the change of the load. It could also be caused by an acceleration or deceleration time that is too short, so prolong the acceleration/deceleration time. Finally, there may be an abnormal load, so check the load.

What causes over voltage in Acc process on Santerno SINUS VEGA 2S Inverter?
- J
  Jonathan WyattAug 29, 2025
  If your Santerno Inverter is showing an overvoltage error during the acceleration process, it could be due to an abnormal AC supply voltage, so check the AC supply voltage. It may also be due to an acceleration time that is too short, so prolong the acceleration time. Additionally, it can happen if the inverter is restarted with a rotating motor, so start when the motor stops.

  joshuahoganAug 31, 2025
  If your Santerno Inverter displays an overvoltage error during constant-speed operation, it could be due to several reasons. An abnormal AC supply voltage may be the cause, so check the AC supply voltage. The acceleration or deceleration time may be too short, so prolong the acceleration or deceleration time. An abnormal change of input voltage could also be the issue, so install an input reactor. Lastly, the load inertia might be too high, so use a suitable dynamic braking device.

What causes motor overload in Santerno Inverter?
- F
  fkingSep 1, 2025
  Motor overload in a Santerno Inverter can occur due to several reasons. An improper V/F curve can cause this, so set the V/F curve and torque boost value correctly. Low AC supply voltage is another potential cause, so check the AC supply voltage. If a common motor is operating at low speed with a large load for a long time, select a special motor designed for such operating conditions. Incorrect setting of the motor overload protection factor can also lead to this issue, so correct the setting. Finally, a blocked motor or sudden change in load can cause overload, so check the load.

What causes inverter module protection in Santerno SINUS VEGA 2S?
- J
  Jennifer MendozaSep 3, 2025
  If your Santerno Inverter is experiencing module protection issues, it could be due to several reasons: * Instant overcurrent - refer to the User’s manual. * Shorted interphase or ground - re-wiring might be required. * Blocked or damaged fan duct - clear the blockage or replace the fan. * High ambient temperature - lower the ambient temperature. * Loose panel wiring or plug-ins - check and re-wire.

How do I troubleshoot RS485 communication failure on a Santerno SINUS VEGA 2S Inverter?
- D
  Diana FloresSep 4, 2025
  If you are experiencing an RS485 communication failure with your Santerno Inverter, it could be due to a wrong baud rate setting, so set the baud rate correctly. It may also be due to a serial port communication error, so press STOP/RESET to reset. Improper setting of alarm conditions can also cause this, so modify FP.02, FP.03 and FFL.12. Finally, the host FC may not be working, so check whether the host FC is working or not and check the wiring.
