Output Current Detection Value Exceeded

What does E.CDO mean?

This fault activates when the inverter's output current surpasses the level defined by Pr. 150 (Output current detection level). It serves as a protective measure, indicating that the motor or load is drawing more current than configured, possibly due to an overload or incorrect parameter settings. Exceeding this limit can lead to inverter or motor damage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review Pr. 151 (Output current detection signal delay time), Pr. 166 (Output current detection signal retention time), and Pr. 167 (Output current detection operation selection) to adjust the detection response if necessary, ruling out transient conditions.

2. 4

   Inspect motor wiring and the motor itself for any abnormalities that could lead to excessive current draw.
