Work with camming

In this section, you'll learn how to make a cam move using KINGSTAR cam functions.

Process of making a cam move

The process below shows how to make a cam move in KINGSTAR:

SetCamTable -> SetAxisCam -> motion functions -> ReleaseAxis

Functions

SetCamTable: selects a cam table by setting the connections to a relevant table.

SetAxisCam: links the axes and starts to cam.

ReleaseAxis: releases an axis from the Stopping state or detaches it from camming or gearing.

 

The following are motion functions. For more information about their uses, see Chapter 5.

• MoveAxisAbsolute: moves an axis to an absolute position.
• MoveAxisContinuousAbsolute: moves an axis to an absolute position. After that, the axis keeps moving using the EndVelocity.
• MoveAxisAdditive: adds a relative distance based on the last commanded position in the Discrete Motion state.
• MoveAxisRelative: moves an axis a specified distance.
• MoveAxisContinuousRelative: moves an axis a specified distance. After that, the axis keeps moving using the EndVelocity.
• MoveAxisVelocity: moves an axis continuously at the specified velocity.
• JogAxis: moves an axis continuously at the specified velocity. After you send a Jog command, the axis will accelerate to the specified velocity and keeps moving at that speed, until you stop it.
• InchAxis: same as JogAxis but it has a maximum distance. After the axis travels the distance it will automatically stop.

Keep in mind that cam defines the behavior of a slave axis, not master. The master axis doesn't know a slave axis is attached to itself. After you cam two axes, only the master should be moved.

Start camming

Take the following steps to implement camming:

• Define a cam table
• Link a slave axis to the master
• Move the master axis: use one of the motion functions to move the master axis.
• Exit camming
