Mode 4: pos. direction - reversing to home mark - to TP
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 at HM_bHomingMark and simultaneous activation of the profile
data set 2 for further reference search.
3. Negative edge at HM_bHomingMark enables home position 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 at HM_bHomingMark enables home position 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").
