Step 4. Specify the slave positions.

Next, we specify the slave positions with the instruction

ET[n]=x,y,z,w

where n indicates the order of the point.

The value, n, starts at zero and may go up to 256. The parameters x,y,z,w indicate the corresponding slave position. For this example, the table may be specified by

ET[0]=,0

ET[1]=,3000

ET[2]=,2250

ET[3]=,1500

This specifies the ECAM table.

Step 5. Enable the ECAM

To enable the ECAM mode, use the command

EB n

where n=1 enables ECAM mode and n=0 disables ECAM mode.

Step 6. Engage the slave motion

To engage the slave motion, use the instruction

EG x,y,z,w

where x,y,z,w are the master positions at which the corresponding slaves must be engaged.

If the value of any parameter is outside the range of one cycle, the cam engages immediately. When the cam is engaged, the slave position is redefined, modulo one cycle.

Step 7. Disengage the slave motion

To disengage the cam, use the command
