The moving distance of the master axis is the source which could
drive the E-Cam
Source selected by P5-88.Y:
Physical axis: auxiliary encoder (linear scale)

Physical axis: pulse command

Virtual axis: PR command / Time axis / Synchronous capture

Functional axis: CAP axis (defined by CAP function)

The position of master axis can be monitored via P5-86. It also can
be written before the E-cam engaged. To change this parameter
will not influence the position of the slave. It is because the moving
distance of master axis remains.
It is used to determine the status of engaged / disengaged between
the master axis and gear box # 1.
The moving distance of the master axis can drive the E-Cam not until
the cam is engaged.
0: disable E-cam function (default value). If the cam is engaged,
the cam will be forced to disengage.
1: enable E-cam function and start to judge the engaged condition
Status can be known via parameter P5-88.S: 0 – Stop; 1 – Engage;
2 – Pre-engage
