PCAM Good Registration Count

PCAM_good_registration_count is the current number of consecutive in-
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_good_registration_count in the Tag Window.

PCAM_good_registration_count is set to zero when power is applied to
the motion controller, or when the position-lock cam for the specified
slave axis is disabled. You can reset this variable to zero (or any other
value) by assigning it a value using an Equation block.

An in-tolerance registration event is one that occurs inside the target
position or nominal length tolerance entered in the Configure Cam block,
as shown below.
