Figure 9-1 DP-V1 Parameter Channel
The parameter channel requires a parameter index and subindex to access parameters.
Drive parameters can be accessed by placing the result of the equations:
If the parameter is 99 or less:
10000 + (S x 10000) + (MM x 100) + ppp
in the parameter Index field of the PROFIdrive request, the sub-index field is always set
to 0.
For example, Pr 01.021 (Preset Reference 1) would be entered as:
10000 + (0 x 10000) + (1 x 100) + 21 = 10121
If the parameter is greater than 99:
10000 + (S x 10000) + (MM x 100) + 99, sub-index is set to (ppp-99).
For example, Pr 03.127 (P2 Speed Feedback) would be entered as:
10000 + (0 x 10000) + (3 x 100) + 99 = 10399 with a sub-index of (127-99) = 28
PROFIdrive Parameters (PNU’s) can be accessed by placing the PNU number in the
parameter index field and if the PNU data type is an array, then the sub-index field may
also be specified.
