What to do if Mitsubishi Electric Inverter motor will not start?
If the motor connected to your Mitsubishi Electric Inverter won't start, consider the following checks: Examine the Pr. 0 Torque boost setting if V/F control is exercised, inspect the main circuit, check the input signals, verify the parameter settings, perform a load inspection, and consider other potential issues.
Why is the motor current large in Mitsubishi Electric FR-D700 Inverter?
A large motor current in your Mitsubishi Electric Inverter might indicate that the load is too heavy. Check the load to ensure it is within the motor's capacity.
How to prevent overheating of Mitsubishi Electric FR-D700 Inverter motor?
To prevent a Mitsubishi Electric Inverter motor from overheating, check for dust accumulation and ensure the motor's fan is functioning correctly. Also, verify that the load isn't excessively heavy.
How to fix abnormal noise from Mitsubishi Electric FR-D700 motor?
To address abnormal noise from a Mitsubishi Electric Inverter motor: check for any mechanical looseness. Also, adjust the Pr. 72 PWM frequency selection.
What to do if Mitsubishi Electric Inverter motor rotates in the opposite direction?
If your Mitsubishi Electric Inverter motor rotates in the opposite direction, verify that the phase sequence of output terminals U, V, W is correct. Also, ensure that the start signals (forward rotation, reverse rotation) are not input simultaneously.
Why speed does not increase on Mitsubishi Electric FR-D700 Inverter?
If the speed of your Mitsubishi Electric Inverter isn't increasing, check that the Pr. 1 Maximum frequency setting is correct.
How to improve Acceleration/deceleration smoothness on Mitsubishi Electric Inverter?
To improve the smoothness of acceleration and deceleration on your Mitsubishi Electric Inverter, check that the acceleration and deceleration time settings are appropriate.
What to do if the speed greatly differs from the setting on Mitsubishi Electric Inverter?
If the speed of your Mitsubishi Electric Inverter greatly differs from the setting, check that the frequency setting signal is correct.
