Step 11: Execute (Test) Your CAM-Based Motion Program
Warning
Before testing your application on actual machinery, you must first verify
that it is safe to do so. This includes insuring that all devices are securely
mounted, all safety equipment is installed and operational, and personnel in
the area have been notified. Failure to address all safety-related issues could
result in injury to personnel and damage to equipment.
Once the download operation is complete, the module is ready to execute the CAM Blocks, motion
programs and Local Logic program. Use the following procedure:
1. Place the PLC in run mode.
2. Enable the servo drives. To enable Axis #1, toggle the %Q offset 18 bit. To enable Axis #2,
toggle The %Q offset 34 bit. Based upon the current module error status, you may also have to
initiate a clear error routine by toggling the %Q offset 0 bit.
3. Have both axes perform a find home routine by toggling the %Q offset 19 bit (find home Axis
#1) and the %Q offset 35 bit (find home Axis #2). At this point, both axes will perform a find
home cycle. Wait until this completes for both axes and the Position Valid %I bits turn on.
The Position Valid %I bit for Axis 1 is the %I offset 17 bit (the 18th %I bit), and for Axis 2 is
the %I offset 33 bit (the 34th %I bit). The resulting display is shown in Figure 16-38.
