Cause : Online Tuning Param Setting Err comes when the parameters that control online tuning are set incorrectly. In OLV control, one of these parameters was set when n6-01 = 2 [Online Tuning Selection = Voltage Correction Tuning]:

• E2-02 [Motor Rated Slip] is set to 30% of the default setting or lower.
• E2-06 [Motor Leakage Inductance] is set to 50% of the default setting or lower.
• E2-03 = 0 [Motor No-Load Current = 0 A] has been set.

Set E2-02, E2-03, and E2-06 correctly.
