Error

I use the FR-A240E-45K, but it often trips during deceleration. (It does not trip during acceleration.)
Is the overcurrent during deceleration (OC3) triggered by rise of the surrounding air temperature?
Or, any other reasons for triggering it?

Answer

The inverter overcurrent shut-off fault indication E.OC1, E.OC2, or E.OC3 is not only displayed when the inverter output current reaches approximately 200% of the rated current, but also the main circuit element is overheated.

This protection works during acceleration, constant-speed operation, and deceleration, and E.OC1, E.OC2, and E.OC3 are displayed, respectively.
This indication does not occur due to any other reasons than overcurrent shut-off.
