Operand Summary - ECAM Mode
operand Description
_EB Contains the state of ECAM mode (0 = disabled, 1 = enabled)
_EGx Contains ecam status for specified axis (0 = engaged, 1= disengaged)
_EMx Contains the cycle of the specified axis
_EP Contains the value of the interval

Example - Using ECAM
The following example illustrates a cam program with a master axis, Z, and two slaves, X and Y.
Instruction Interpretation
#A;V1=0
Label; Initialize variable
PA 0,0;BGXY;AMXY
Go to position 0,0 on X and Y axes
EA Z
Z axis as the Master for ECAM
EM 0,0,4000
Change for Z is 4000, zero for X, Y
EP400,0
ECAM interval is 400 counts with zero start
ET[0]=0,0
When master is at 0 position; 1st point.

10th point in the ECAM table
ET[10]=0,0
Starting point for next cycle
EB 1
Enable ECAM mode
JGZ=4000
Set Z to jog at 4000
EG 0,0
Engage both X and Y when Master = 0
BGZ
Begin jog on Z axis
#LOOP;JP#LOOP,V1=0
Loop until the variable is set
