Mitsubishi Electric FREQROL-B F.A.Q.

How do I reset the Mitsubishi Electric FREQROL-B to factory settings?

To reset the FREQROL-B to factory settings, enter the parameter setting mode, navigate to the reset parameter (Pr. 79), and set it to 1. Confirm the setting to initiate the reset process. Ensure the drive is stopped before performing this action.

What should I do if the FREQROL-B drive trips frequently?

Frequent tripping can be caused by overload conditions, improper parameter settings, or external disturbances. Check the load conditions, verify all parameter settings, and inspect external connections for any issues. Consider consulting the manual for specific error codes.

How can I change the acceleration and deceleration time on the FREQROL-B?

To change the acceleration and deceleration time, adjust parameters Pr. 7 and Pr. 8 respectively. Enter the parameter setting mode, navigate to the desired parameter, and set the value according to your application requirements.

What maintenance is required for the FREQROL-B drive?

Regular maintenance includes inspecting the cooling system, checking for dust accumulation, tightening terminal screws, and verifying that all electrical connections are secure. Perform a visual inspection for any signs of wear or damage.

Can the FREQROL-B be used with multiple motors?

Yes, the FREQROL-B can be used to control multiple motors, but ensure that the combined current does not exceed the drive's rated output. Configure the parameters suitably for multi-motor operation and consider using motor protection devices.

How do I troubleshoot an overvoltage fault in the FREQROL-B?

An overvoltage fault can be caused by a sudden deceleration, regenerative energy from the motor, or a high input voltage. Check the power supply voltage, increase deceleration time, and consider installing a braking resistor if excessive regenerative energy is suspected.

What is the procedure for setting up communication with the FREQROL-B via RS-485?

To set up RS-485 communication, configure the communication parameters (Pr. 117 to Pr. 124) to match your network settings. Connect the RS-485 terminals to your control system, ensuring correct wiring and termination.

How do I perform a manual speed control operation on the FREQROL-B?

For manual speed control, use the frequency setting potentiometer or the digital operator to set the desired frequency. Ensure the drive is in local control mode and verify the motor runs at the desired speed.

What should I check if the motor does not start when the FREQROL-B is powered on?

If the motor does not start, verify the start signal wiring, check for any active fault codes, and ensure that the drive is not in stop mode. Confirm that all necessary start conditions are met as per the configured settings.

How can I improve the energy efficiency of the FREQROL-B drive system?

To improve energy efficiency, ensure the drive is properly matched to the motor and application, optimize acceleration and deceleration times, and utilize energy-saving functions like the automatic energy-saving mode if available.
