To fix an input phase loss issue on your Mitsubishi Electric Inverter: * Wire the cables properly. * Repair any breaks in the cable. * Check the Pr. 872 Input phase loss protection selection setting. * Set Pr. 872 = "0" (without input phase loss protection) when three-phase input voltage is largely unbalanced.
How to fix overcurrent trip during acceleration on Mitsubishi Electric 700 Inverter?
To resolve an overcurrent trip during acceleration with your Mitsubishi Electric Inverter, consider these steps: * Increase the acceleration time. * If "E.OC1" is always lit at starting, disconnect the motor and start the inverter. * Check the wiring for output short circuits or ground faults. * Set 50Hz in Pr. 3 Base frequency. * Lower the stall prevention operation level. * Activate the fast-response current limit operation. * Set the base voltage (rated voltage of the motor, etc.) in Pr. 19 Base frequency voltage.
Why is my Mitsubishi Electric 700 heatsink overheating?
If your Mitsubishi Electric Inverter's heatsink is overheating: * Ensure the surrounding air temperature is within the specifications. * Clean the heatsink. * Replace the cooling fan.
How to troubleshoot stall prevention (overcurrent) on Mitsubishi Electric 700?
To troubleshoot stall prevention (overcurrent) on your Mitsubishi Electric Inverter: * Increase or decrease the Pr. 0 Torque boost setting by 1%. * Set a larger value in Pr. 7 Acceleration time and Pr. 8 Deceleration time. * Reduce the load weight. * Try Advanced magnetic flux vector control and General-purpose magnetic flux vector control. * Change the Pr. 14 Load pattern selection setting. * Set stall prevention operation current in Pr. 22 Stall prevention operation level.
What should I do if my Mitsubishi Electric 700 Inverter shows a motor overload trip?
If your Mitsubishi Electric Inverter indicates a motor overload trip, consider these actions: * Reduce the load weight. * For a constant-torque motor, set the constant-torque motor in Pr. 71 Applied motor. * Check that stall prevention operation setting is correct.
How do I fix a regenerative overvoltage trip during acceleration on my Mitsubishi Electric 700?
To address a regenerative overvoltage trip during acceleration on your Mitsubishi Electric Inverter: * Decrease the acceleration time. * Check that regeneration avoidance function (Pr. 882, Pr. 883, Pr. 885, Pr. 886) is used. * Set the Pr.22 Stall prevention operation level correctly.
How to prevent regenerative overvoltage trip during constant speed on Mitsubishi Electric 700?
To prevent regenerative overvoltage trips during constant speed with your Mitsubishi Electric Inverter: * Keep the load stable. * Check that regeneration avoidance function (Pr. 882, Pr. 883, Pr. 885, Pr. 886) is used. * Use the brake resistor, brake unit or power regeneration common converter (FR-CV) as required. * Set the Pr.22 Stall prevention operation level correctly.
What causes regenerative overvoltage trip during deceleration or stop in Mitsubishi Electric 700 Inverter?
A regenerative overvoltage trip during deceleration or stop on your Mitsubishi Electric Inverter can be addressed by: * Increasing the deceleration time. * Lengthening the brake cycle. * Using a brake resistor, brake unit, or power regeneration common converter (FR-CV) as needed.
How to resolve inverter overload trip on Mitsubishi Electric 700 Inverter?
To resolve an inverter overload trip on your Mitsubishi Electric Inverter, consider the following: * Increase acceleration/deceleration time. * Adjust the torque boost setting. * Set the load pattern selection setting according to the load pattern of the using machine. * Reduce the load weight. * Ensure the surrounding air temperature is within specified limits.
Why does Mitsubishi Electric Inverter show overcurrent trip during deceleration or stop?
If your Mitsubishi Electric Inverter experiences an overcurrent trip during deceleration or stop, consider the following: * Increase the deceleration time. * Check the wiring for output short circuits or ground faults. * Check the mechanical brake operation. * Lower the setting of stall prevention operation level. * Activate the fast-response current limit operation.
