4.5 Reference Handling

4.5.1 Bus Speed Reference Value
In FC profile (parameter 8-10 Control Word Profile = [0] Frequency converter profile), the reference is scaled as a normalized
relative value in percent. The value is transmitted in hexadecimal:
•
0% = 0 hex
•
100% = 4000 hex
•
-100% = C000 hex
Depending on the setting of parameter 3-00 Reference Range, the reference is scaled from -maximum to +maximum or from
minimum to maximum.
