Cam axis length per cycle [Cam axis cycle units]
(c) Coordinate data format
The coordinate data format is defined in coordinates of more than 2 points
for one cam cycle. The coordinate data is represented as Input value and
output value.
• Input value : Cam axis current value per cycle.
• Output value : Stroke position from cam reference position.
With this format, [Pr.441] Cam stroke amount (150n,
150n) of output axis parameter is ignored and output value of the
coordinate data becomes cam stroke position.
Refer to Section 6.2 for setting methods of cam data.
