1. Teaching Unit
Select the teaching (trace) unit to move it to a target position, from "Camera", "First Head" or "Last
Head". Normally, select "Camera" to view the trace point on the vision monitor.
2. Step Mode (inching mode)
Use this mode to move the teaching (trace) unit in specified steps (mm). As long as the [Step Mode]
button is depressed, the inching mode takes priority over other motions so that continuous
movement will not change to high-speed movement even if an axis move key is held down.
[Step Mode] button
When this button is depressed, the teaching unit moves a specified distance (mm) each time you
press an axis move key. The inching distance can be set from 0.000 to 10.000 mm.
3. Speed
Set the speed (%) to move the teaching unit. This speed can be set from 1 to 100 by pressing the UP
arrow button. Press an axis move key to start moving the teaching unit at the specified speed.
Holding down the axis move key allows the teaching unit to move at a high speed. Using a slow
speed ("10" or "20") is recommended for safety, although you may at first feel the movement is slow.
