Fieldbus adapter
Actual Value
As described earlier in section Control interface on page 230, Actual Values are
words containing drive values.
Actual Value scaling
The scaling of the integers sent to the fieldbus as Actual Values depends on the
resolution of the selected drive parameter. Except as noted for
ACT1 and ACT2 below,
scale the feedback integer using the resolution listed for the parameter in section
Complete parameter list on page 69. For example:
Data words 5 and 6 are scaled as follows:
Virtual addresses of the drive control
The virtual address area of the drive control is allocated as follows:
Feedback integer Parameter resolution Scaled Value
1 0.1 mA 1 · 0.1 mA = 0.1 mA
10 0.1% 10 · 0.1% = 1%
