What to do if my Mitsubishi Electric Inverter shows overcurrent trip during acceleration?
- B
  Brian SheaAug 23, 2025
  If your Mitsubishi Electric Inverter is showing an overcurrent trip during acceleration, try the following: Set a longer acceleration time. If 'E.OC1' appears at start, disconnect the motor and restart the inverter. If the error persists, the inverter may be faulty, so contact your sales representative. Check the wiring for output short circuit and ground fault. If the rated motor frequency is 50Hz, set Pr. 3 Base frequency to 50Hz. Lower the stall prevention operation level. Activate the stall prevention operation and the fast-response current limit operation (Pr.156). If operating with frequent regenerative driving, set the base voltage in Pr. 19 Base frequency voltage.

What does it mean when my Mitsubishi Electric FR-D700 shows a motor overload trip?
- W
  William EdwardsSep 2, 2025
  A motor overload trip on your Mitsubishi Electric Inverter means the electronic thermal relay function for motor protection has activated. Try reducing the load. If you're using a constant-torque motor, set the constant-torque motor in Pr. 71 Applied motor. Adjust the stall prevention operation level accordingly.

What does it mean when my Mitsubishi Electric FR-D700 shows an inverter overload trip?
- A
  Amy PhillipsSep 1, 2025
  An inverter overload trip on your Mitsubishi Electric Inverter means the electronic thermal relay function, which protects the inverter elements, has been activated. To resolve this, try increasing the acceleration/deceleration time, adjusting Pr. 0 Torque boost setting, setting Pr. 14 Load pattern selection appropriately, reducing the load, or ensuring the surrounding air temperature is within the specified limits.

What to do if my Mitsubishi Electric FR-D700 displays regenerative overvoltage trip during acceleration?
- M
  Mark MillerAug 31, 2025
  If your Mitsubishi Electric Inverter displays a regenerative overvoltage trip during acceleration, try shortening the acceleration time. Use the regeneration avoidance function (Pr. 882, Pr. 883, Pr. 885, Pr. 886). Ensure Pr.22 Stall prevention operation level is set correctly. Set Pr.154 Voltage reduction selection during stall prevention operation = '11'.

What to do if my Mitsubishi Electric FR-D700 Inverter displays regenerative overvoltage trip during constant speed?
- R
  reesewilliamAug 29, 2025
  If your Mitsubishi Electric Inverter displays a regenerative overvoltage trip during constant speed operation, ensure the load is stable. Utilize the regeneration avoidance function (Pr. 882, Pr. 883, Pr. 885, Pr. 886). Consider using a brake resistor, brake unit, or power regeneration common converter (FR-CV) if necessary. Ensure Pr.22 Stall prevention operation level is correctly set. Set Pr.154 Voltage reduction selection during stall prevention operation = '11'.

What to do if my Mitsubishi Electric FR-D700 Inverter displays regenerative overvoltage trip during deceleration or stop?
- S
  Sara Miller DDSAug 28, 2025
  If your Mitsubishi Electric Inverter displays a regenerative overvoltage trip during deceleration or at a stop, try the following: Increase the deceleration time. Lengthen the brake cycle. Use the regeneration avoidance function (Pr. 882, Pr. 883, Pr. 885, Pr. 886). Use a brake resistor, brake unit, or power regeneration common converter (FR-CV) as needed. Set Pr.154 Voltage reduction selection during stall prevention operation = '11'.

What causes a stall prevention (overcurrent) on a Mitsubishi Electric Inverter and how to fix it?
- M
  Michael FoxAug 27, 2025
  The overcurrent stall prevention on your Mitsubishi Electric Inverter has been activated. To resolve this: * Increase or decrease the Pr. 0 Torque boost setting by 1% and check the motor status. * Set a larger value in Pr. 7 Acceleration time and Pr. 8 Deceleration time. * Reduce the load weight. * Try General-purpose magnetic flux vector control. * Adjust the Pr. 13 Starting frequency setting. * Change the Pr. 14 Load pattern selection setting. * Set the stall prevention operation current in Pr. 22 Stall prevention operation level.

Why does my Mitsubishi Electric Inverter show an undervoltage error?
- E
  Emily RogersAug 27, 2025
  An undervoltage error on your Mitsubishi Electric Inverter indicates that the voltage at the main circuit power supply has dropped. Investigate the devices on the power supply line, including the power supply unit itself, to find the cause.

  caroline69Aug 26, 2025
  If your Mitsubishi Electric Inverter shows an overcurrent trip during deceleration or at a stop, try these steps: Increase the deceleration time. Check the wiring, looking for output short circuits or ground faults. Verify that the mechanical brake isn't activating too early. Also, consider lowering the stall prevention operation level and activating the stall prevention operation and the fast-response current limit operation (Pr.156).

What to do if my Mitsubishi Electric FR-D700 is showing overcurrent trip during constant speed?
- A
  Alexandra JohnsonAug 25, 2025
  If your Mitsubishi Electric Inverter is showing an overcurrent trip during constant speed operation, make sure the load is stable. Also, check the wiring for any output short circuits or ground faults. Try lowering the stall prevention operation level and activating both the stall prevention operation and the fast-response current limit operation (Pr.156).
