Optimization of the current control parameters
In order to be able to support all possible loads ex factory, the terminal was parameterized with moderate
controller characteristics. Current regulation can be improved significantly by adapting the controller
parameters to the actual load.
To determine the settings a current pulse is applied to the load. This pulse can be picked up with an
oscilloscope or with TwinCAT ScopeView.
For evaluation with TwinCAT ScopeView the set and actual current is displayed in the synchronous info
data.
