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.
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 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.
How to fix module overheat in Inovance MD280NT3.7GB?
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 MD280NT3.7GB Inverter?
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 MD280NT3.7GB?
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 Inverter shows AC drive overload?
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 MD280NT3.7GB Inverter?
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 MD280NT3.7GB Inverter?
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.
