8.1.6 Control parameters of the load controller

The control parameters can be defined in 3 different ways.
The memory of the load controller contains 5 standard parameter sets.
Depending on the characteristics of the controlled system, a PID triple value can be se-
lected and activated.
The following standard parameter sets can be chosen:
Very fast
Fast
Normal
Slow
Very slow
Alternatively, the PID parameters can be directly selected and set within the predefined
value range.

With the method of adapting the control parameters, the characteristic data of the con-
trolled system are acquired with an adaption procedure whereupon matching PID pa-
rameters will be calculated.
If possible, the adaption load should be 100 %.
