What causes motor overheat with Inovance MD280NT3.7GB?
Motor overheat when using an Inovance Inverter can be caused by the cabling of the temperature sensor becoming loose or the motor temperature being too high. Check the temperature sensor cabling and eliminate the cabling fault. You can also lower the carrier frequency or adopt other heat radiation measures.
How to resolve initial position fault on Inovance MD280NT3.7GB Inverter?
An initial position fault may occur because the motor parameters are not set based on the actual situation. Check whether the motor parameters are set correctly and whether the setting of rated current is too small.
Why does Inovance Inverter report overcurrent and overvoltage frequently?
If your Inovance AC drive frequently reports overcurrent and overvoltage, it could be due to improperly set motor parameters, improper acceleration/deceleration time, or load fluctuations. You can try setting the motor parameters in group F1 again and setting a proper acceleration/deceleration time.
How to fix current detection fault in Inovance MD280NT3.7GB Inverter?
A current detection fault in your Inovance Inverter may be due to a faulty HALL device or a faulty drive board. To resolve this, replace the faulty HALL device or the faulty drive board.
How to fix overcurrent during acceleration in Inovance MD280NT3.7GB?
Overcurrent during acceleration in your Inovance Inverter may be due to several reasons: a grounded or short-circuited output circuit, too short acceleration time, inappropriate manual torque boost or V/F curve, low voltage, startup operation performed on a rotating motor, a sudden load during acceleration, or an AC drive model of too small power class. To resolve this, you can: * Replace external faults. * Increase the acceleration time. * Adjust the manual torque boost or V/F curve. * Adjust the voltage to the normal range. * Select rotational speed tracking restart or start the motor after it stops. * Remove the added load. * Select an AC drive of a higher power class.
What to do if Inovance MD280NT3.7GB has a control power supply fault?
If your Inovance Inverter has a control power supply fault, it could be because the input voltage is not within the allowable range or the input voltage is not stable, causing the bus voltage to jump frequently around the undervoltage threshold. You can try to adjust the input voltage to the allowable range and wait at least five minutes after power failure until the input voltage becomes normal, and then power on the AC drive again.
What to do if Inovance MD280NT3.7GB reports power output phase loss?
If your Inovance Inverter reports a power output phase loss, it could be due to a faulty cable connecting the AC drive and the motor, the AC drive's three-phase outputs being unbalanced when the motor is running. Try to replace external faults and check whether the motor three-phase winding is normal.
What causes power input phase loss in Inovance MD280NT3.7GB Inverter?
Power input phase loss in your Inovance Inverter may be due to the three-phase power input being abnormal. You can try to replace external faults.
What causes fast current limit timeout on Inovance MD280NT3.7GB?
A fast current limit timeout on your Inovance Inverter may be due to: the acceleration/deceleration time being too short, inappropriate manual torque boost or V/F curve, startup operation performed on the rotating motor, or the load being too heavy. To address this: * Increase the acceleration/deceleration time. * Adjust the manual torque boost or V/F curve. * Use rotational speed tracking startup or perform startup after the motor stops. * Use an AC drive of a higher power class.
What to do if Inovance MD280NT3.7GB displays motor overload?
If your Inovance Inverter indicates a motor overload, possible causes include FB-01 being set improperly, the load being too heavy or locked-rotor occurring on the motor, or the AC drive model being of too small a power class. To resolve this: * Set FB-01 correctly. * Reduce the load and check the motor and mechanical conditions. * Select an AC drive of larger power class.
