Lenze i510 - Optimisation of the Control Loops; Speed Controller; Imax Controller; Current Controller

7.4 Opmisaon of the control loops
The following speed controller, Imax controller and current controller parameters are calcula-
ted and set automacally and in the cour
se of the automac calibraon of the motor.
Details
•
The calibraon process can be carried out in "energised" or in "non-energised" mode.
•
The calibraon process takes all controllers into consideraon at the same me; it is not
possible to control the speed controller Imax controller, and current controller separately.
•
Without carrying out the calibraon, standard values are preset according to the voltage
and power of the inverter.
•
When the automac calibraon has been carried out, further adaptaon is neither required
nor recommended for typical applicaons.
If these parameters have to be adapted, this has to be done very carefully. An
incorrect seng may hav
e a negave impact on the control system.
