position, pointing to values in an array of waypoints in the
camshaft emulation. The way points are defined in a Pdata
array with up to 1000 rows
Since the camshaft is a repetitive function, the array must
be defined with continuos segments. The camshaft profile
between waypoints is determined by linear interpolation
between adjacent waypoints.
Sets the number of ”cogs” that Gear.In increases with each
cycle (mS) The momentary value can be observed in
Gear.InAct.
The resulting Gear.Pos can also be modified directly with
Gear.Offset.
The resulting position, Gear.CamPos, is the current profile
value (interpolated) times Gear.CamScale.
Indicate relative position in cam.
PData Defines one waypoint of cam profile.
Pos Mod On (clr) Connects additional command values from gearbox function.

The gearbox is also used to scale the input signal for the ”Position lock CAM”. In
this mode, the system emulates a cam-wheel. The CAM profile is defined by a
number of PDATA statements and the gearbox is used to create the index into that
table.
The start of the table is set by the Gear.CamLine variable and the length (in
