Name	Type	Description
ModuloPositions	BOOL	If Modulo TRUE, all positions are interpreted as modulo. The cam function is repeated cyclically. The parameter ModuloFactor is used for calculating the modulo cycle.
ModuloFactor	LREAL	ModuloFactor indicates the length of a modulo cycle in the positioning unit of the axis and is only used if Modulo TRUE.
OnCompensation	LREAL	Compensation time for the rising edge of the cam in [s]. For negative values of OnCompensation the switching time is brought forward, otherwise it is delayed.
OffCompensation	LREAL	Compensation time for the falling edge of the cam in [s]. For negative values of OffCompensation the switching time is brought forward, otherwise it is delayed.
Hysteresis	LREAL	Hysteresis of the switching operations for reversing the rotation direction. The hysteresis is specified in the position unit of the axis. (available from library 3.3.27.0)
BreakRelease	BOOL	Brake enable for brake cams on this cam track
Force	BOOL	The digital output is activated independent of the cams on this track. Disable has priority over Force.
Disable	BOOL	The digital output is deactivated independent of the cams on this track. Disable has priority over Force.
