Speed Control (ASR): C5
User constants for speed control are shown in the following table.
* 1. When using V/f with PG control, 0.00 to 300.00. The flux vector setting ranges are given.
* 2. When the control method changes, the factory setting is changed. The flux vector control factory settings are given. Refer to Factory Settings that
Change with the Control Method (A1-02).
* 3. When C6-01 = 1, the upper limit is 400.0.
