Deactivation time for time-based cam
Deactivation time is also taken into account in setting a time-based cam.
Deactivation time must be:
● Deactivation time ≤ activation time + ON duration
Activation and deactivation times can vary independently of the I/O and can, therefore,
influence the ON duration of the time-based cam.

Cam track activation

The _enableCamTrack command activates the cam track. On activation, the defaults are
transferred to the system variables. If you explicitly want to use other values, these must be
transferred with the command.
The following parameters are transferred via the _enableCamTrack command:
● Cam track data
● Output cam data
If you do not transfer any new data when activating the command, the defaults are used.
4.2.3.6 Cam track deactivation
Cam tracks are deactivated automatically or via a command.
Automatic deactivation
Automatic cam track deactivation is only possible when the configuration data
octBaseCfg.keepEnabledOutOfTrackRange has been set to NO. In this case deactivation
occurs on exiting the domain of the cam track, i.e. the track start (in a negative direction) or
the track end (in a positive direction). It is not possible to reverse the direction of movement
repeatedly within the track length. Output cams can therefore be output repeatedly. Automatic
deactivation is set as default. As of V4.1 you can set the deactivation via the configuration data.
Note
In the cam track Configuration window, you can configure the automatic deactivation via

Deactivation via command
The _disableCamTrack command is used to deactivate the cam track.
