Features of E-Cam
DO.CAM_AREA
(DO no.= 0x18)
 Digital Output (DO): CAM_ARE
A
. If this DO is ON, it means
the E-Cam axis is in the setting area.
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
0: disable E-cam function (default value). If the cam is engaged,
the cam will be forced to disengage.
