Mode 1: neg. direction - via home mark - to TP
Procedure:
1. Movement in negative direction with profile data set 1.
2. Positive edge at HM_bHomingMark activates profile data set 2 for the 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").
Mode 2: pos. direction - reversing to limit switch - via home mark - to TP
Procedure:
1. Movement in positive direction with profile data set 1.
2. Reversing to positive travel range limit switch.
3. Positive edge at HM_bHomingMark activates profile data set 2 for the further reference search.
4. Negative edge at HM_bHomingMark enables home position detection.
5. The following positive edge of the encoder zero pulse/touch probe sensor sets the reference.
