Search for the cam axis current value per cycle
When calculating the cam axis current value per cycle using cam data, the position corresponding to "[Cd.618] Cam position
calculation: Cam axis feed current value" is searched using cam data based on the position specified by "[Cd.617] Cam
position calculation: Cam axis current value per cycle".
The following shows the order of the search for "[Cd.618] Cam position calculation: Cam axis feed current value".
■Stroke ratio data format
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, return to the 0th point and search until the search
starting point.
If the corresponding position is not found even though the whole area of the cam data has been searched, the warning "Cam
position calculation cam axis 1 cycle current value calculation disable" (warning code: 0C64H) 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:
0C64H) will occur.
Ex.
When "[Cd.617] Cam position calculation: Cam axis current value per cycle" is corresponding to the 0th point of cam data
0
(Cam reference position)
At the 0th point
• Searches until between the 255th point and the 256th point (last point) in order of the cam data between the 0th point and
the 1st point and between the 1st point and the 2nd point.
Ex.
When "[Cd.617] Cam position calculation: Cam axis current value per cycle" is corresponding to the 128th point of cam data
0
(Cam reference position)
At the 0th point
• Searches until between the 255th point and the 256th point (last point) in order of the cam data between the 128th point
and the 129th point and between the 130th point and the 131th point.
