Why Mitsubishi Electric FR-A500L motor rotates in opposite direction?
If the motor connected to your Mitsubishi Electric Inverter rotates in the opposite direction, check that the phase sequence of output terminals U, V, and W is correct.
What to do if Mitsubishi Electric FR-A500L Inverter motor remains stopped?
To address a motor that remains stopped when using a Mitsubishi Electric Inverter, check the main circuit.
What to do if Mitsubishi Electric FR-A500L ambient temperature too high?
If the ambient temperature around your Mitsubishi Electric Inverter is too high, set the ambient temperature within the specified limits.
What to do if Mitsubishi Electric FR-A500L Inverter motor used under overload?
If the motor connected to your Mitsubishi Electric Inverter is being used under overload, reduce the load. You may also need to increase the motor and inverter capacities.
What to do if Mitsubishi Electric FR-A500L experiences sudden load change?
If your Mitsubishi Electric Inverter experiences a sudden load change, check for an output short circuit or ground fault. To resolve this, keep the load stable.
What to do if Mitsubishi Electric FR-A500L gate power supply error?
If you are experiencing a gate power supply error with your Mitsubishi Electric Inverter, it could be due to: * A short circuit in the gate output. * An error in the control power supply board. To fix this, repair any short-circuited sections or replace the control power supply board.
What to do if Mitsubishi Electric Inverter cooling fan power supply error?
If you encounter a cooling fan power supply error on your Mitsubishi Electric Inverter, it could be due to: * A short circuit in the cooling fan's power supply output. * An abnormal cooling fan power supply. * A blown fuse. To resolve this, repair any short-circuited sections, replace the cooling fan power supply, or replace the fuse.
What to do if Mitsubishi Electric FR-A500L Inverter control board ambient temperature error?
If the Mitsubishi Electric Inverter displays a control board ambient temperature error, it might be caused by: * An issue with the cooling fan. * The ambient temperature being too high. To fix this, try replacing the cooling fan and ensuring the ambient temperature stays within the specified limits.
What to do if Mitsubishi Electric FR-A500L capacitor overcurrent?
If your Mitsubishi Electric Inverter is showing a capacitor overcurrent, it may be due to: * A short circuit in the DC circuit. * An output short circuit or ground fault (check the motor winding and insulation resistance). To resolve this, repair any short-circuited sections and replace the DC fuse. Also, repair any output short circuits and ground faults, which may involve repairing or replacing the motor.
What to do if Mitsubishi Electric FR-A500L Inverter brake unit cooling fin overheating?
If the brake unit cooling fin of your Mitsubishi Electric Inverter is overheating, consider the following: * Check if the brake unit's usage frequency is appropriate. * Inspect the cooling fins for any clogs. * Verify the inverter unit cooling fan is functioning correctly. Suggested solutions include reducing the load GD2, reducing the braking frequency, cleaning the cooling fins, or replacing the cooling fan.
