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
EQ x,y,z,w
where x,y,z,w are the corresponding slave axes are disengaged.

This disengages the slave axis at a specified master position. If the parameter is outside the master
cycle, the stopping is instantaneous.
Programmed start and stop can be used only when the master moves forward.
Some Examples
To illustrate the complete process, consider the cam relationship described by
