3.3.1. Speed PID Control

The table shows the control configurations where speed control is active.

Note: "N.A." means that the specific mode is not available at all. "Not Active" means that the
specific mode is available but speed control is not active in that mode.
Note: The speed control PID will work under the default parameter setting, but tuning the pa-
rameters is highly recommended in order to optimize motor control performance. The two flux
motor control principles are specially dependant on proper tuning to yield their full potential.
