Speed Control (ASR): C5
User constants for speed control are shown in the following table.
* 1. When the control method is changed, the Inverter reverts to factory settings. (The flux vector control factory settings will be displayed.)
* 2. The setting range is 1.00 to 3.00 for flux vector control and open-loop vector control 2.
