14.4.1 Current Loop Evaluation
Figure 46shows the current control loop. To evaluate the design or to re-tune the current loop PID
coefficients, the first thing to do is to check all the parameters up to date in use. This can be done by click
Schematic View to bring out a new window with the schematics shown in Figure 47. If any values are
different from those in the physical circuitry, one needs to update them before doing any control loop re-
tuning.
