FX Positioning Control Systems 4 - 39
4.3.3 Program example
In the example that follows, a two speed positioning instruction is used to move a drill 100 mm toward
a block of wood with a high speed pulse frequency of 40 kHz. When the drill reaches the wood, the
speed decreases to 10 kHz. The drill is then driven for 50 mm into the wood before decelerating to
stop.
The two speed positioning operation is illustrated in the following graph. Neither the zero point
return nor the JOG instructions are used in the ladder program.
