How to fix module overheat in Inovance Inverter?
- K
  Kathy BakerAug 31, 2025
  If your Inovance Inverter module is overheating, it could be due to several reasons: the ambient temperature being too high, the air filter being blocked, the fan being damaged, the thermally sensitive resistor of the module being damaged, or the inverter module itself being damaged. To resolve this: * Lower the ambient temperature. * Clean the air filter. * Replace the damaged fan. * Replace the damaged thermally sensitive resistor. * Replace the inverter module.

What causes undervoltage in Inovance Inverter?
- C
  Christopher OwensAug 30, 2025
  Undervoltage in your Inovance Inverter can be triggered by several factors: an instantaneous power failure on the input power supply, the AC drive's input voltage not being within the allowable range, an abnormal bus voltage, faulty rectifier bridge and buffer resistor, a faulty drive board, or a faulty main control board. You can try the following: * Reset the fault. * Adjust the voltage to the normal range.

What causes overvoltage at constant speed in Inovance MD280NT37P?
- A
  amber58Aug 29, 2025
  If your Inovance Inverter is showing overvoltage at constant speed, it could be due to the input voltage being too high or an external force driving the motor during deceleration. To fix this: * Adjust the voltage to the normal range. * Cancel the external force or install the braking resistor.

What to do if Inovance MD280NT37P shows AC drive overload?
- C
  Carol SimsAug 28, 2025
  If the Inovance Inverter displays an AC drive overload, it may be due to the load being too heavy, locked-rotor occurring on the motor, or the AC drive model being of too small a power class. To solve this: * Reduce the load and check the motor and mechanical conditions. * Select an AC drive of a higher power class.

What causes overvoltage during acceleration in Inovance Inverter?
- M
  Michael ChoiAug 27, 2025
  Overvoltage during acceleration in your Inovance Inverter can occur due to several reasons: the input voltage being too high, an external force driving the motor during acceleration, the acceleration time being too short, or the braking unit and braking resistor not being installed. You can try the following solutions: * Adjust the voltage to the normal range. * Cancel the external force or install a braking resistor. * Increase the acceleration time. * Install the braking unit and braking resistor.

How to resolve overvoltage during deceleration in Inovance MD280NT37P?
- B
  Brenda Nichols PhDAug 27, 2025
  If you are experiencing overvoltage during deceleration with your Inovance Inverter, the possible causes are: the input voltage is too high, an external force drives the motor during deceleration, the deceleration time is too short, or the braking unit and braking resistor are not installed. Here are some possible solutions: * Adjust the voltage to the normal range. * Cancel the external force or install the braking resistor. * Increase the deceleration time. * Install the braking unit and braking resistor.

Why does Inovance MD280NT37P Inverter show overcurrent at constant speed?
- J
  Jeremy WarnerAug 26, 2025
  An Inovance Inverter displaying overcurrent at a constant speed may be caused by a grounded or short-circuited output circuit, a sudden load added during operation, or the AC drive model being of too small a power class. To address this: * Replace external faults. * Remove the added load. * Select an AC drive of a higher power class.

What to do if Inovance Inverter shows overcurrent during deceleration?
- J
  Jose GrahamAug 25, 2025
  If your Inovance Inverter indicates overcurrent during deceleration, it could be due to a grounded or short-circuited output circuit, a deceleration time that is too short, low voltage, a sudden load added during deceleration, or the absence of a braking unit and braking resistor. Consider the following solutions: * Replace external faults. * Increase the deceleration time. * Adjust the voltage to the normal range. * Remove the added load. * Install the braking unit and braking resistor.
