CiA402 Homing method 04
Processes:
Case 1:
Axis has not yet activated reference switch:
1. Movement in positive direction with profile data set 1.
2. Positive edge of the reference switch activates touch probe detection and change to
profile data set 2.
3. The following positive edge of the encoder zero pulse/touch probe sensor sets the
reference ( 0x607C ).
4. Absolute positioning to target position (C02643) with profile data set 2 (if 0x60FB/
7 = "0").
Case 2:
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").
