[Pr.438] Cam axis cycle unit setting
Set the command units for the cam axis input per cycle to be used for cam control.
These units are used for setting the cam axis length per cycle and the cam axis current value per cycle.
There is no influence on the control for the parameter for monitor display.
Refer to the following.
Page 90 Overview of output axis module
[Pr.439] Cam axis length per cycle
Set the length per cycle of the cam axis to generate the cam axis current value per cycle.
The unit settings are in the cam axis cycle units (Page 91 Units for the output axis).
Set a value within the range from 1 to 2147483647.
The cam axis length per cycle can be changed during synchronous control by setting "1: Valid" in "[Pr.442] Cam axis length
per cycle change setting". The value set in "[Pr.439] Cam axis length per cycle" is valid when the cam axis current value per
cycle passes through the 0th point of cam data, or is on the 0th point.
For cam data using the coordinate data format, if the input value of the last coordinate is less than "[Pr.439] Cam axis length
per cycle", the coordinate is calculated from the line segment between the nearest two coordinates from the last coordinate.
The following shows an example in the case that "[Pr.439] Cam axis length per cycle" is changed to exceed the input value of
the last coordinate of cam data using the coordinate data format during synchronous control.
[Coordinate data format]
• Cam axis length per cycle: 4194304 [pulse]
• Cam stroke amount: 4194304 [pulse]
