Title: Feed-to-Length Application using MC_TouchProbe for Position Latching

6. Sequence of Operations
Cold start the application and activate debug mode:
1) If there are axis alarms, clear them using Switch 6. If the alarms cannot be cleared using Switch 6,
power will have to be cycled.
2) Use Switch 1 for enabling both axes.
3) Make sure Switch 2 is low, ensuring that the machine is in manual mode at first.
4) Switch 3 jogs the feed axis
5) Switch 4 starts the homing sequence. The feed axis homes to a latch sensor first, and then comes back
to the closest C channel pulse. To simulate the latch, use the LATCH switch on the demo corresponding
to the SGDH axis. After a small time delay after the latch-induced stop, the feed axis moves to C pulse
and sets position as zero (home). Turn switch 4 off after the axis completes homing.
6) To start auto production, the axis has to be homed. Turn Switch 2 and Switch 5 on. To start at its
production velocity, use the LATCH switch, as this enables the feed-to-length algorithm. The axis stops
after a pre-decided distance beyond the feed axis latched position. It then waits for a press/cut operation,
and starts moving again looking for the next part latch. Auto cycle can be stopped by switching Switch 5
off.
