(1) An operation error will occur, and the cam position calculation will not be executed
if:
• Cam No. specified with (S1) is outside the range of 0 to 256.
• The cam No. data specified with (S1) does not exist in the cam open area.
• The device numbers storing the cam position calculation control data specified
with (S2) are outside the range.
• (S2), (D) are not even-numbered devices.
• Cam position calculation type specified with cam position calculation control data
is set to other than 0 or 1.
• Cam axis length per cycle is outside the range of 1 to 2147483647.
• Cam axis current value per cycle is outside the range of 0 to (cam axis length per
cycle).
• The device numbers storing the cam position calculation result specified with (D)
are outside the range.
• The cam axis current value per cycle cannot be calculated by the cam axis
current value per cycle calculation.
