7. Restore the P gain (p1715) and integral time (p1717) of the current controller back to the
original values.
8. Again measure a current controller setpoint step.
Figure 4-34 Example: after optimization/tuning
In most cases, the voltage precontrol is correctly set after the eddy current compensation
(see example). If required, you can correct again using p1734.
