OmniTurn Control
Welcome to our world
This manual will guide first time users to startup, home, enter, edit, and
run programs. First we will discuss the control layout. On the upper left-
hand side of the control you will see a large red button called emergency
stop. (1). Twist and pull, button should snap out. Next check the other E
stop located on the palm box make sure this is also disengaged. (2). Now
you are ready to press the yellow control on button. (3). The first screen
that comes up will ask you if you want to back up your files on a disc.
Press the letter Y for yes or N for no on the keyboard. The next screen
will prompt turn servos on. The blue button in figure (4) is the servo on
button, press this now. This brings you to the Jog menu screen with a
prompt “HOME MUST BE ESTABLISHED”.
See page 5.
There are two other buttons on the control a green button (5) which is
cycle start and a small red button (6) that is motion stop. Note: The cycle
startbuttononthecontrolisonlyactiveonretrofitswithouttheACspindle
drives option. Otherwise the two black palm buttons on the operator sta-
tion activate cycle start fig (7). The motion stop button is used to stop
slide motion while running a program in the automatic mode. Below the
emergency stop button is the spindle speed pot. This will adjust the speed
of the spindle. Note: This only works with the AC spindle drive option.
Under the speed pot is the spindle on / off switch (8). This is used to
manually stop the spindle.
Jog Menu
[Chapter 1, Page 1.3 - 1.7 in OmniTurn Programming Manual]
The jog menu allows the operator to perform several functions. 1.Estab-
lishing home. 2. Move slide manually either incrementally or continu-
ously. 3.Set tool offsets
The first three choices on the menu are continuous jog moves made in
Inches per minute feed rates 1: slow 1 IPM 2: medium 10 IPM 3: 100
IPM.
To activate these moves select 1, 2, and 3, on the main keypad. The
joystick on the control will move the slides in one of four directions: X +,
X- Z+ or Z-. Choose speed number 2:10 IPM. Then point the joystick
(9) down in the X+ direction and hold. The slide will move toward you at
10 IPM until you release it. Now push the joystick to the left in the Z-
direction. Try the different speeds and get comfortable with this mode.
Use caution when jogging in the fast mode, and be careful not to over
travel the axis’s. Also if there are tools mounted on the slide be aware of
their position in relationship to the spindle or work piece.

Jog Menu
Incremental Jog selections
[Chapter 1, Page 1.5 in OmniTurn Programming Manual]
There are five incremental jog selections numbered four through
eight.
•4. = .00005
•5.= .001
•6.= .010
•7.= .100
•8.= 1.000
Selecting an increment by pressing the appropriate number on the key-
pad, and moving the joystick in one of the four directions will move the
slide one increment at a time. It does not matter how long you hold it.
The slide will move only one increment each time you move the joy-
stick. Note: Selection becomes highlighted on menu screen see Fig 1.
9. Establishing Home [Chapter 1, Pages 1.8-1.10]
The OmniTurn slides must be homed before a program may be entered.
To home the slides you must select a continuous jog speed, usually this
is the medium jog speed number 2 on the keypad. After selecting me-
dium jog hold the joystick in the X+ direction until you have traveled at
least 2 marks on the X-axis scale. Then jog back between the first mark
and zero. Repeat this process for the Z axis traveling in the Z- direction
then back between the first mark and zero. Your pointer should look
like the pictures to the right for both X & Z-axis’s. When your slides are
in position press the number 9 key and the cycle start palm buttons. The
slides move to the zero mark on the scale. Home has been established.
S. Set Zero [Chapter 1]
Pressing the S key on the control then pressing the X key and the Z key
will zero the position numbers for the slide at whatever position they
are at. This is useful if you are cutting a collet or soft chuck jaws. Set-
ting zero does not effect the Home position.
H. Go Home [Chapter 1]
At any time when you are in the jog menu, and you want to return the
slides home you may press the H key. The prompt on the screen will
say “DEPRESS X TO HOME X AND Z TO HOME Z”. Always press
Z first to clear the tools away from the spindle then X.
T. Set Tool [Chapter 1]
Selecting the T key from the menu will allow you to enter tool offsets in
the computer for your program. This will be discussed later.
EXIT
To exit jog menu press the escape key on the upper left hand corner of
the Keypad.
