mode
Signal name, description PROFIBUS bitposn–setFct. No.
Set reference point 71 – x PosStw.1
An axis can be assigned a required actual value (P0160) (actual value setting) at any position using the
0/1 edge of the input signal. This is only possible if a traversing block is not being executed
0/1 signal The reference point is set, i.e. the value P0160 is assigned as actual position.
After this, the axis is considered to have been referenced (output signal ”reference point
set” = ”1”).
Note:
If the reference point is still set again (new command), then for the backlash compensation, the system
behaves as if the reference point was not set again.
Coupling is activated (from SW 3.3) 72 – x PosStw.4
The coupling, set via P0410, is activated using this input signal.
1 signal No function
0/1 signal Activate coupling
The coupling is activated corresponding to P0410.
P0410
= 1 or 2 ––> Coupling is switched–in
= 3 or 4 ––> The signal has no significance
= 5 or 6 ––> The coupled position is transferred into the queue (being prepared)
= 7 ––> Coupling is switched–in at the absolute position of the master drive
(from SW 4.1)
= 8 ––> Coupling via the traversing program to the absolute position of the
master drive (from SW 4.1)
0 signal Coupling–out, initial status
Note:
 Recommended for powering–up with a precise position:
Use the fast input I0.x on the control board.
––> refer to the input signal ”activate coupling via I0.x” (function number 73)
 The position when switching–in the coupling is displayed in P0425:0.
 The ”axis coupling” function is described in Chapter 6.3.
