What to do if Senlan Hope800 Inverter shows overcurrent during acceleration?
- N
  Nathaniel MurrayAug 5, 2025
  If the Senlan Inverter shows an overcurrent during acceleration, it could be due to several reasons. The acceleration time might be too short, so try increasing it. The V/F curve could be improper, requiring you to regulate the V/F curve or the torque boost setting. If a running motor restarts, set the start mode to smooth start and restart the motor after it completely stops. Check the input power in case of low power grid voltage. If the inverter capacity is too small, use one with a larger capacity. Finally, perform the parameter auto-tuning if it hasn't been done for vector control.

What to do if Senlan Hope800 shows overcurrent during constant-speed operation?
- T
  Tammie BrownAug 10, 2025
  If the Senlan Inverter shows overcurrent during constant-speed operation, it could be due to a sudden change of load, so try to reduce it. Check the load for errors. Also, check the input power in case of low power grid voltage. If the inverter capacity is too small, use an inverter with larger capacity. Finally, perform the parameter auto-tuning if it hasn't been done for vector control.

Why does Senlan Inverter show overvoltage during deceleration?
- A
  Allison DrakeAug 15, 2025
  If the Senlan Inverter shows overvoltage during deceleration, it could be because the deceleration time is too short; increase the deceleration time. If there's potential energy load or the load's inertial torque is large, employ a dynamic braking unit. Check the input power if the input voltage is abnormal. Also, adjust the ASR parameter to reduce overshoot if the ASR setting is improper.

  Lauren DicksonAug 20, 2025
  If the Senlan Inverter indicates an overcurrent during deceleration, consider these potential causes. The deceleration time might be too short, so increase it. If there's a potential energy load or the inertial torque of the load is large, install an external dynamic braking unit. If the inverter capacity is too small, use an inverter with a larger capacity. Also, perform the parameter auto-tuning if it hasn't been done for vector control.

Why does Senlan Hope800 Inverter show overcurrent at start?
- A
  Anthony AlvarezAug 26, 2025
  If the Senlan Inverter shows an overcurrent at start, it could be due to an inter-phase or grounding short-circuit inside the motor or between wirings; check the motor and wiring. It can also happen because of voltage overhigh at start, check the setting of “torque boost”.

  If the Senlan Inverter shows overvoltage during acceleration, check the input power if the input voltage is abnormal. If a running motor restarts, set the start mode to “smooth start” and restart the motor after it stops completely.
