Why does Inovance MD280NT3.7GB Inverter display "H&" and stops immediately?
If the AC drive display is normal upon power-on but "H&" is displayed after running and the AC drive stops immediately, the cooling fan is damaged or locked-rotor occurs. Replace the damaged fan.
What to do if Inovance MD280NT3.7GB Inverter 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.
Why does Inovance 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.
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.
What does "Err23" displayed at power-on mean for Inovance MD280NT3.7GB Inverter?
If "Err23" is displayed at power-on, the motor or the motor output cable is short-circuited to the ground. Measure the insulation of the motor and the output cable with a megger.
Why is there no display at power-on on Inovance MD280NT3.7GB Inverter?
If there is no display at power-on, there is no power supply to the AC drive or the power input to the AC drive is too low. Check the power supply. Also, the cable connecting the control board and the drive board and the operation panel breaks. Re-connect the 8-core and 16-core cables.
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.
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.
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 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.
