Pink .......................................... Target Speed

Green........................................ Drive Output (volts)

Yellow ...................................... Pressure

− Note the Sum Error

. This number gives an indication of the position

error throughout the entire move. If the same move is repeated, this

value can be compared to previous moves to determine whether the

control has improved or worsened. If the number decreases, the

control has improved.

• If the system controls fairly well, which this one does, increase the speed.

Here it is increased to 20.000 in/sec. The plot time can also be reduced to

• Increase the proportional gain until some oscillation appears, then back off

10-20%. On this system that point is about 70. The plot looks like this:

− The Sum Error

decreased from 53 million to 27 million.
