25.5 FVAL_DONE BOOL FALSE 1 = set actual value on-the-fly executed
Effects of the setting
Based on the example "set actual value" to 400 mm (at position 200 mm), you can see how
this setting shifts the coordinate system. Resultant effects:
● The position of the working range is not physically shifted.
● The various points, such as the software limit switches, are assigned new coordinate
values.
● The cams retain their coordinate values, and are therefore located at a different physical
position.
● When the axis is synchronized and the cam processing is enabled, the actual position
may skip cam edges or complete cams as a result of this setting.
● Status changes of the cam which would normally trigger an interrupt may be lost.
Note
For information on switching characteristics of time-based cams, refer to chapter
"Influence of settings on the switching characteristics of time-based cam
s (Page 103)".
