Note
This definition of the switch-on area is possible for all modulo and non-modulo axes.
ON duration
The ON duration of the output cam depends on the velocity at which the axis traverses the
output cam length.
Direction-dependent switching
The output cam is activated:
● When the axis position is between the start and end positions, and the axis is moving in
the programmed effective direction
The output cam is switched off:
● When the axis position is outside the start or end position
● When the motion direction is not the same as the assigned effective direction
● When the axis position value is shifted outside the switch-on area
● When commands are issued that deactivate the output cam, e.g. _disableOutputCam,
_setOutputCamState, and _resetOutputCam

Limits imposed by starting position and ON duration
The output cam is switched on:
● At the starting position.
If the starting position is overrun again during the ON duration, the time-based cam is not
switched on again. It is not possible to retrigger a time-based cam.
The output cam is switched off:
● When the assigned time period expires
● When commands are issued that deactivate the output cam, e.g. _disableOutputCam,
_setOutputCamState and _resetOutputCam
