Descriptions
The movement of the master axis is the signal which enables E-
Cam operation of the servo drive.
Source of Master Axis
(P5-88 Y Settings)
The command source of the master axis is determined by P5-88 Y
settings.
Physical axes:
P5-88 Y=1. Linear Encoder (CN5)
P5-88 Y=2. Pulse Command (CN1)
Output axis:
P5-88 Y=0. Capture source setting. (Defined by Capture
function, P5-39 B settings)
Virtual axes:
P5-88 Y=3. PR command (Internal signal)
P5-88 Y=4. 1ms clock (Internal signal)
P5-88 Y=5. Synchronous Capture Axis (P5-39 B, Mark
tracking)
Position of Master Axis
(P5-86)
Using P5-86 can monitor the position of the master axis. Before E-
Cam is engaged, P5-86 can be set and changed still. Doing this
will not affect the position of the slave axis because the
movement of the master axis does not change as well.
When the E-Cam is activated (P5-88 X=1), the pulse will be
counted in P5-86. The P5-86 should be an increasing number.
If not, reverse the pulse direction (not motor direction).
