Example - Electronic CAM

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.

ET[1]=40,20

2nd point in the ECAM table

ET[2]=120,60

3rd point in the ECAM table

ET[3]=240,120

4th point in the ECAM table

ET[4]=280,140

5th point in the ECAM table

ET[5]=280,140

6th point in the ECAM table

ET[6]=280,140

7th point in the ECAM table

ET[7]=240,120

8th point in the ECAM table

ET[8]=120,60

9th point in the ECAM table

ET[9]=40,20

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

EQ2000,2000

Disengage X and Y when Master = 2000

MF,, 2000

Wait until the Master goes to 2000

ST Z

Stop the Z axis motion

EB 0

Exit the ECAM mode

EN

End of the program

The above example shows how the ECAM program is structured and how the commands can be given to the controller. The next page provides the results captured by the WSDK program. This shows how the motion will be seen during the ECAM cycles. The first graph is for the X axis, the second graph shows the cycle on the Y axis and the third graph shows the cycle of the Z axis.
