Setup
Selecting reference marks
Selections are made by repeatedly touching the Reference marks choice field to cycle through all the avail-
able encoder reference mark types.
In this example, the reference mark choices (None, Manual, Single and Absolute) are cycled by repeatedly
touching the Axis choice field.
None
No encoder reference marks are used. Machine zero will be established at the encoder locations encoun-
tered when the system is powered on. The machine zero location can be changed at any time using the
Machine Zero Set function described later in this chapter.
Manual
You will be prompted to move the stage to position the encoders at a point that you wish to use as machine
zero each time the system is powered. The manual reference mark selection is commonly used with “hard
stop” machine references. The machine zero location can be changed at any time using the Machine Zero
Set function described later in this chapter.
Single
You will be prompted to move the stage to cross encoder reference marks on each axis each time the
system is powered. The reference mark crossing points of each encoder are used to determine the machine
zero position. The machine zero location can be changed at any time using the Machine Zero Set function
described later in this chapter.
Absolute
Selecting Absolute reference marks causes a Teach button
to be displayed. Touch the Teach button to initiate a pro-
cess that will guide you through the steps required to cross
encoder reference marks. Follow the instructions provided on the screen. You will be prompted
to move the stage to cross reference marks on each axis. The reference mark crossing points of
each encoder are used to determine the machine zero position. Sometimes the resulting machine zero posi-
tion for absolute reference marks can be located outside the stage boundaries. In these cases, this machine
zero location can be changed by the user to a more convenient “home” position for measurements using
the Machine Zero Set function described on the next page.
