1.3 Console
Context sensitive help
The MILLPWRG2 uses an intuitive method to aid the user when 
assistance is required.  When assistance is needed with a feature, the 
User Manual can be displayed directly at the point which describes the 
feature.
To use this help, in this example, the console is in PGM mode, and a 
Linear Engraving cycle is being programed.  It is desired to see 
descriptions of the cycle parameters, and the cycle itself. The 
following steps describe the actions...

Count direction
When programming a part using MILLPWRG2, table movement and 
tool movement are determined by the use of positive or negative 
numbers. MILLPWR
G2 has been factory set with the following 
positive and negative count directions for the X, Y and Z-axes:
X axis
The table will move to the left and the tool will move to the right for 
a positive count direction.
Y axis
The table will move toward you while the tool...

2.1 Conventions
Absolute and incremental work piece positions
Absolute work piece positions
Absolute coordinates are position coordinates that are referenced to 
the datum of the coordinate system (origin). Each position on the work 
piece is uniquely defined by its absolute coordinates.
Example 1: Holes dimensioned in absolute coordinates
Incremental work piece positions
Incremental coordinates are referenced to a previous step within the 
program, which serves as the relative...

Setting the datum
Overview
Datum is the workpiece zero or absolute zero, and is a point of 
reference that the MILLPWR
G2 bases all of the parts coordinates 
from.
A datum must be established for every job. Datums location may be 
indicated on the print; or the operator may establish a datum that 
allows most of the parts dimensions be entered directly using the 
least amount of calculations. 
When establishing datum, it may be easiest to locate a known point...

Move table
Non cutting mode
You can make or change jog moves when in DRO mode with the servos 
on.
In mm units the jog increment is 20 microns, 200 microns and 2000 
microns respectively.
Changing the mode
Jog move modes are performed at the currently active feedrate. The  
active Jog is selected by pressing the appropriate soft key, then 
pressing the appropriate ARROW key to move the table in the direction 
required....

2.2 Manual Machine Positioning
Press the appropriate ARROW key (or soft key) to move the table in the 
direction required for the axis move. The table will move at the 
currently active jogging speed. The table will move until the ARROW 
key is released.
Adjusting the feedrate
The Feedrate Override potentiometer can be used to override the 
currently active feedrate or rapid rate for machine moves. The switch 
provides a range of 0% to max% as defined in Job setup, see page...
