Loading...Why Inovance MD500 Controller shows AC drive overload?
The AC drive overload on your Inovance Controller may be due to a load that is too heavy or a locked rotor on the motor. You should reduce the load or check the motor and mechanical conditions. Alternatively, consider replacing the drive with one of a larger power class.
What causes output phase loss in Inovance MD500?
Output phase loss in your Inovance Controller can stem from several issues. It may be due to damaged motor winding, in this case check resistance between motor wires. The cable connecting the AC drive and the motor might be abnormal, so check for wiring errors and ensure the output cable is connected properly. Also, check whether the motor three-phase winding is normal.
What to do if Inovance Controller detects overvoltage when heavy load is suddenly removed?
If the Inovance Controller detects overvoltage when a heavy load is suddenly removed or during deceleration, first ensure that F3-23 (overvoltage stall enable) is enabled. If the issue persists, gradually increase the setting of F3-24/F3-25 (overvoltage stall gain, default is 30) by 10, up to a maximum of 100. Alternatively, you can gradually decrease the setting of F3-22 (overvoltage stall actuating voltage, default is 770V) by 10 V, down to a minimum of 700 V.
How to fix motor oscillation during running with Inovance Controller?
To address motor oscillation during running with the Inovance Controller, gradually increase the setting of F3-11 (V/F oscillation suppression gain) by 10. The maximum permissible setting is 100.
Why is there a very large current during running with the Inovance MD500?
If you're experiencing a very large current during running with your Inovance Controller, ensure that the rated motor voltage (F1-02) and rated motor frequency (F1-04) are set correctly. Also, gradually decrease the setting of F3-01 (torque boost) by 0.5%.
What to do if Inovance MD500 Controller detects overload or overcurrent during motor start?
If your Inovance Controller detects an overload or overcurrent fault during motor start, set F1-27, F1-28 and F1-30 correctly.
What to do if Inovance MD500 Controller shows motor overload?
If the Inovance Controller indicates a motor overload, it might be because the load is too heavy, or the motor has a locked rotor. Try reducing the load or inspecting the motor and mechanical components. If the issue persists, consider using a drive with a larger power class.
What causes IGBT overheat in Inovance Controller and how to fix it?
IGBT overheat in your Inovance Controller can be caused by several factors. The ambient temperature may be too high, so lower it. Other potential solutions include cleaning the ventilation, replacing the cooling fan if it's damaged, replacing the damaged thermally sensitive resistor, or as a last resort, replacing the AC Drive IGBT.
What to do if Inovance MD500 detects overload or overcurrent during motor running?
If your Inovance Controller is showing an overload or overcurrent during motor running, set the motor parameters F1-01 to F1-05 according to the motor nameplate. Also, select a proper motor auto-tuning mode by setting F1-37 and perform motor auto-tuning. If possible, select dynamic auto-tuning.
