Input/output Setpoints, entered via the source, are evaluated at the input for the fol-
evaluation lowing couplings:
––> via the angular incremental encoder (P0891 = 0 or 1)
––> via PROFIBUS–DP (P0891 = 4)

SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
Input format (slave drive):
– Xext (external position reference value, number 50207)
– dXcorExt (correction, external position reference value, number
50209)
Position in MSR = input value @
The following applies:
The output is evaluated ––> PROFIBUS–DP
Output format (master drive):
– XsollP (position reference value, number 50208)
– XistP (position actual value, number 50206)
– dXcor (correction, position reference/actual value, 50210)
Output value = position in MSR @
The following applies:
The output value must be able to be represented using 32 bits. This
means that the maximum traversing distance that can be repre-
sented is:

The standard settings for PROFIBUS–DP are:
– P0884 = 10000
– P0895 = 10000
– P0896 = 10000 MSR (mm)
Recommendation: Modify the standard setting as follows to achieve
the best possible resolution:
– P0884 = 2048
– P0895 = 2048
– P0896 = 5 MSR (mm)
For this setting, the resolution is
and the traversing distance that can be represented is " 5.24 m.
