Method
2 Positive limit switch with index pulse.
1. If positive limit switch inactive:
Run at search speed in positive direction to the positive limit switch.
Run at crawl speed in negative direction until the limit switch becomes inactive,
then on to first index pulse. This position is saved as a reference point.
If configured: Run at travel speed to axis zero point.
–1 Negative stop with index pulse 1)
2. Run at search speed in negative direction to stop.
Run at crawl speed in positive direction to next index pulse. This position is saved
as a reference point.
If configured: Run at travel speed to axis zero point.
–2 Positive stop with index pulse 1)
3. Run at search speed in positive direction to stop.
Run at crawl speed in negative direction to next index pulse. This position is saved
as a reference point.
If configured: Run at travel speed to axis zero point.
17 Negative limit switch
4. If negative limit switch inactive:
Run at search speed in negative direction to the negative limit switch.
Run at crawl speed in positive direction until limit switch becomes inactive.
This position is saved as a reference point.
If configured: Run at travel speed to axis zero point.
18 Positive limit switch
5. If positive limit switch inactive:
Run at search speed in positive direction to the positive limit switch.
Run at crawl speed in negative direction until limit switch becomes inactive.
This position is saved as a reference point.
If configured: Run at travel speed to axis zero point.
–17 Negative stop 1)2)
6. Run at search speed in negative direction to stop. This position is saved
as a reference point.
If configured: Run at travel speed to axis zero point.
–18 Positive stop 1)2)
7. Run at search speed in positive direction to stop. This position is saved
as a reference point.
If configured: Run at travel speed to axis zero point.
33 Index pulse in a negative direction
8. Run at crawl speed in negative direction to index pulse. This position is saved
as a reference point.
If configured: Run at travel speed to axis zero point.
34 Index pulse in a negative direction
9. Run at crawl speed in positive direction to index pulse. This position is saved
as a reference point.
If configured: Run at travel speed to axis zero point.
35 Current position
10. The current position is saved as the reference point.
If configured: Run at travel speed to axis zero point.
Note: If the reference system is shifted, runs to the limit switch or fixed stop are possible.
The are therefore generally used for rotating axes.
