5.1 Sprayer Example
5.1.1
Description A
reversible DC motor drives a paint sprayer up and down a vertical
assembly
. A quadrature encoder on the drive shaft senses the direction and
relative position of the sprayer
. Channel 1 of the HSC will be used to
enable the sprayer during a pre-defined section of travel. (See Figure 5-1.)
The encoder resolution is 500 cycles per revolution. One shaft revolution
equals 1 inch of sprayer travel. When encoder signal A leads, the direction
of travel is up.
