Chapter 5 Synchronous Control Initial Position
• If the corresponding position is not found until the last point of the cam data, searches
from the 0th point of the cam data.
• Searches until between the 127th point and the 128th point in order of the cam data
between the 0th point and the 1st point and between the 1st point and the 2nd point.
[Coordinate data format]
(1) The range before the 1st point of cam data
When the 1st point of the cam data is larger than 0 and "[Cd.617] Cam position
calculation: Cam axis current value per cycle < the 1st point of cam data", the
position corresponding to "[Cd.618] Cam position calculation: Cam axis feed
current value" is searched from the range before the 1st point of the cam data.
If the corresponding position is not found in the range of (1), searches in the range
of (2). If the corresponding position is not found in the range of (2) either, searches
in the range of (3).
If the corresponding position is not found even though the range of (1) to (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.
Example) When "[Cd.617] Cam position calculation: Cam axis current value per cycle" is
set before the 1st point of cam data

• Searches from the range of (1).
• If the corresponding position is not found in the range of (1), searches from the 1st
point of the cam data in the range of (2).
