6.1 How to Control the AF-600 FP

6.1.1 Reference Handling

Select the frequency converter configuration mode in par. H-40 Configuration Mode.
[0] Open Loop

[3] Closed Loop

6.1.2 Open Loop
For open loop operation, the reference represents the desired output speed of the frequency converter.
The speed reference value is transmitted to the frequency converter as a relative value in %.
6.1.3 Closed Loop
In closed loop operation the feedback/reference is scaled from 1 to par. CL-14 Maximum Reference/Feedb..
NB!
Please refer to the Troubleshooting section to see an example of reference scaling.
All references provided to the frequency converter are added to the total reference value.
If a reference is to be controlled by the LonWorks bus only, please ensure that all other reference inputs are zero.
This means that digital and analog input terminals should not be used for reference signals.
The default setting (0%) should be maintained for preset references in par. C-05 Multi-step Frequency 1 - 8
