4.3 Creating a STEP 7 project
Connecting SIMOVERT MASTERDRIVES MC to the Technology-CPU

Product Information, 03/2008, A5E00272072-05
Significance:
The "Reference point detected" feedback signal (acknowledgement) is connected to the
encoder interface via U923.i001. If reference cam and encoder zero mark or encoder zero
mark only are used for referencing, then referencing is performed using the reference point
detection in the Motion Control. However, if only a reference cam is used for referencing, the
position measured value memory in Motion Control is used for referencing.
However, if reference cams and encoder zero mark or encoder zero mark only are used for
referencing, binector B210 (reference point detected acknowledgement) should be set in
U923.i001 (reference value detected checkback signal, encoder interface).
If however, only reference cams are to be used for referencing, binector B212
(acknowledgement that the measured value is valid) should be set in U923.i001 (reference
value detected checkback signal, encoder interface).
Parameter: P183 index 1 (position sensing configuration)
Significance:
The position detection configuration is entered in this parameter.
xx1x = The 1st zero position to the right of the coarse pulse (reference cam) is evaluated.
xx2x = The 1st zero position to the left of the coarse pulse (reference cam) is evaluated.
(x means not relevant)
The STEP 7 project is now configured. The MASTERDRIVES MC is set in the next step.
