PCAM_missing_registration_count is incremented when a registration
event is missed, and is reset to zero when the next good (in-tolerance)
registration event occurs.
PCAM_missing_registration_count is set to zero when power is applied
to the motion controller. It can also be reset to zero (or any other value)
using an equation block.
Bad Registration Count
PCAM_bad_registration_count is the current number of consecutive out-
of-tolerance registration events, which have occurred on the registering
axis for a position-lock cam with auto-correction enabled.
In the Tag Explorer, select both Axis System Variables and the desired
axis, then select PCAM_bad_registration_count in the Tag Window.
