Revision February, 2017     7-29 
E-Cam provided by this servo drive and below is its functional diagram: 
 
  Master Axis, the description is as follows: 
Function 
The moving distance of the master axis is the source which could 
drive the E-Cam 
Source of Master 
Axis 
The Setting Value 
of P5-88 Y 
Source selected by P5-88.Y: 
  Auxiliary encoder (linear scale) 
  Pulse command 
  PR command  
  Time axis 
  Synchronous capture axis 
  CAP axis (defined by CAP function) 
Position of Master 
Axis 
P5-86 
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. 
  Clutch, the description is as follows: 
Function 
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. 
Activate E-cam 
function 
P5-88.X 
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 starts to judge the engaged condition 
E-Cam Status 
Status can be known via parameter P5-88.S: 0 – Stop; 1 – Engage; 2 – 
Pre-engage
