Motion Control
 Reset mechanism after alarm stops
When the packing machine stops because of an alarm, the E-Cam phase might shift because of
the external force or other factors. Correct the E-Cam phase before restarting the machine so it
can cut and pack correctly. The wrap feeder has the E-Cam phase alignment function which can
7
automatically complete the alignment by reading the mark positions. For the cutter axis, use
Macro #D to complete the phase alignment before the machine resumes operation. Macro #D
calculates the deviation between the cutter current position and the target position corresponding
to the master axis. Then, it writes the deviation data to the specified PR incremental position
command and triggers this PR command to complete the E-Cam phase alignment.
 Manually adjust the slave axis
To manually adjust the packing wrap to the position near the cutting spot, use the virtual pulses
(P2.077) to fine-tune the positions of the wrap feeder and cutter axes, so the machine can
perform the first cut at the correct position. To adjust the slave axis position during packing
machine operation, you can also use the virtual pulse function to fine-tune the position. In the
virtual pulse function, you can select whether to mask the master pulses and the virtual pulse
compensation type. For detailed settings, refer to Section 7.3.10.
