Procedures:
Case 1:
Axis has not yet activated the reference switch:
1. Movement in positive direction with profile data set 1.
2. Reversing with positive edge of the reference switch and change to profile data set 2.
3. Negative 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.
5. Absolute positioning to target position (
C02643 ) with profile data set 2 (if C02641 = "0").
Case 2: Axis already stands on the reference switch:
1. Movement in negative direction with profile data set 2.
2. Negative edge of the reference switch activates touch probe detection.
3. The following positive edge of the encoder zero pulse/touch probe sensor sets the reference.
4. Absolute positioning to target position (
C02643 ) with profile data set 2 (if C02641 = "0").
