Case 3:
Axis already stands on reference switch:
1. Movement in negative direction with profile data set 2.
2. Reversing with negative edge of reference switch.
3. Positive edge of the reference switch activates touch probe detection.
4. The following positive edge of the encoder zero pulse/touch probe sensor sets the
reference ( 0x607C ).
5. Absolute positioning to target position (C02643) with profile data set 2 (if 0x60FB/
7 = "0").

Processes:
Case 1:
Axis does not activate reference switch on the way to the limit switch:
1. Movement in negative direction with profile data set 1.
2. Reversing to negative travel range limit switch.
3. Reversing with positive edge of the reference switch and change to profile data set 2.
4. Negative edge of the reference switch activates touch probe detection.
5. The following positive edge of the encoder zero pulse/touch probe sensor sets the
reference ( 0x607C ).
6. Absolute positioning to target position (C02643) with profile data set 2 (if 0x60FB/
7 = "0").
