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 master positions at which the corresponding slave axes are disengaged.

Figure 6.4 - Electronic Cam Example
This disengages the slave axis at a specified master position. If the parameter is outside the master
cycle, the stopping is instantaneous.
To illustrate the complete process, consider the cam relationship described by
the equation:
Y = 0.5 * X + 100 sin (0.18*X)
where X is the master, with a cycle of 2000 counts.
The cam table can be constructed manually, point by point, or automatically by a program. The
following program includes the set-up.
