Why does Inovance MD280NT2.2GB Inverter show overcurrent at constant speed?
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 MD280NT2.2GB shows overcurrent during deceleration?
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.
