Chapter 5 Synchronous Control Initial Position
(2) The range within the cam data
When "[Cd.617] Cam position calculation: Cam axis current value per cycle < the
last point of cam data", the position corresponding to "[Cd.618] Cam position
calculation: Cam axis feed current value" is searched from the range of the cam
data.
When "the nth point of cam data
[Cd.617] Cam position calculation: Cam axis
current value per cycle < the n + 1st point of cam data", the position corresponding
to "[Cd.618] Cam position calculation: Cam axis feed current value" is searched
from the nth point of cam data.
If "[Cd.617] Cam position calculation: Cam axis current value per cycle" is in the
middle of the cam data and the corresponding position is not found until the last
point of the cam data, returns to the 1st point and searches until the search starting
point.
If the corresponding position is not found in the range of (2), searches in the range
of (3).
If the corresponding position is not found even though the range of (2) and (3) has
been searched, the warning "Cam position calculation cam axis 1 cycle current
value calculation disable" (warning code: 834) will occur in reciprocated cam
pattern.
For the feed cam, calculates "[Cd.618] Cam position calculation: Cam axis feed
current value" by the stroke difference and searches again from the 0th point to the
whole range. If the corresponding position is not found even though the search
process starts again, the warning "Cam position calculation cam axis 1 cycle
current value calculation disable" (warning code: 834) will occur.

• Searches until between the 4th point and the 5th point (last point) in order of the cam
data between the 1st point and the 2nd point and between the 2nd point and the 3rd
point.
• If the corresponding position is not found until the last point of the cam data, searches
from the range of (3).
