* 1. These are values for a 400-V class Inverter. Multiply the values by approx. 1.5 for the 575-V class Inverter.
* 2. When the control method is changed, the Inverter reverts to factory settings. (The open loop vector control factory settings will
be displayed.)
* 3. E1-11 and E1-12 are disregarded when set to 0.0.
* 4. E1-13 is set to the same value as E1-05 by autotuning.
