Possible causes

The torque reference exceeded 20% during Auto-Tuning. The results from Auto-Tuning the no-load current exceeded 80%. LED Operator Display Cause Motor data entered during Auto-Tuning was incorrect. Auto-Tuning calculated values outside the parameter setting range, assigning the iron-core saturation coefficient (E2-07, -08) a temporary value. LED Operator Display Cause • The motor line-to-line resistance and the motor-rated current are not consistent with one another. • The correct current rating printed on the nameplate was not entered into T1-04. LED Operator Display Cause Motor data or data entered during Auto-Tuning was incorrect. Motor output and motor-rated current settings (T1-02 and T1-04) do not match. Motor output and no-load current settings (T1-04 and E2-03) do not match. Data required when Auto-Tuning for OLV Control or Stationary Auto-Tuning. Base frequency and base motor rotations (T1-05 and T1-07) do not match. LED Operator Display Cause Incorrect motor data entered during Auto-Tuning. The wiring is faulty. Load is too heavy. LED Operator Display Cause Auto-Tuning canceled by pressing STOP button. LED Operator Display Cause Motor data entered during Auto-Tuning was incorrect. Auto-Tuning did not complete within designated time frame. Drive-calculated values outside parameter setting range.
