Operating
mode
Signal name, description PROFIBUS bitposn–setFct. No.
Activate teach–in (edge) (from SW 4.1) 64 – x PosStw.6
The ”teach–in” function is activated using this input signal.
When activated, the actual position reference value is entered as position reference value for the se-
lected traversing block.
1 signal No effect
1/0 signal Resets the ”teach–in successful” output signal
0 signal No effect
1/0 edge Activates ”teach–in” and transfer the instantaneous axis position into the teach–in block
1 signal
0 signal
Input signal ”activate teach–in (edge)”
1 signal
0 signal
Output signal ”teach–in successful”
Accept the axis
position
Note:
 Prerequisites to activate the ”teach–in” function:
– ”Positioning” mode ––> P0700 = 3
– Traversing program isn’t running ––> Output signal ”drive stationary” = ”1”
– Axis is referenced ––> Output signal ”reference point set” = ”1”
 Refer under the index entry ”Output signal – teach–in successful”
 The ”teach–in” function is described in Chapter 6.13.
Control requested/no control requested – x x STW1.10
1 signal This input signal must be set so that process data, transferred from the PROFIBUS
master, is accepted by the slave and becomes effective.
Recommendation:
The input signal should only be set to ”1”, after the PROFIBUS slave has signaled back a
realistic status using the status bit ”control requested/no control possible” = ”1”.
0 signal Data transferred from the PROFIBUS master is rejected by the slave, i.e. it is accepted as
zero.
Start referencing/cancel referencing 65 – x STW1.11
... starts the reference point approach of an axis.
0/1 signal The reference point approach is started
1/0 signal A reference point approach which has been started is interrupted
The drive brakes with the deceleration rate specified in P0104 (maximum deceleration).
The ”reference point set” output signal remains at ”0”.
