About Motion Control
This section describes the positioning systems found in KVAL machinery. There are three basic
types of motion control methods used in KVAL Machinery.
Sequencing:
Sequencing is a series of events executed in a predetermined order. Most KVAL machines use a
form of sequential motion control. A typical series of events for a KVAL machine are:
1.
Move the door into position.
2.
Clamp the door.
3.
Make the cuts.
4.
Unclamp the door.
5.
Move the door out
.
6.
Wait for the next door.
Point to Point:
Point to point motion control involves moving a load from one fixed position to another fixed
position at a constant speed and along one line (axis X,Y, or Z). A typical point to point would be
a drill with a fixed-depth. The drill is either retracted or extended using a pneumatic cylinder.
Typically the drills travel is limited by physical stops.
Incremental:
Incremental motion control is used when the load is required to be moved with high accuracy to
multiple locations, sometimes in multiple directions (axes). A typical KVAL usage for this system
is a computer controlled router in a door light machine where there is great variety in the cut size,
shape and location.
Basic Control Circuit
This section describes a basic control circuit. The Figure below shows a block diagram of a com-
mon control circuit. There are four parts to a motion control system:
