Figure 4-37 Measuring Input Configuration
SIMODRIVE 611U
Parameterize the SIMODRIVE 611U with SimoCom U so that input I0.x addresses the
measuring input.
Use the MC_MeasuringInput technology function in the user program to make the edge
selection:
● positive edge
● falling edge
If you select another setting, the last valid value is taken over (rising or falling).
Comment on 611U-internal edge detection in HW versions up to 6SN1118-xxxxx--xxx1:
● For travel in the positive direction, only the 1 → 0 signal change is detected as a
measuring signal. For travel in the negative direction, only the 0 → 1 edge is recognized
as measuring signal. You must take this into account when activating the measuring
input.
