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.

The main menu screen will allow you four choices: Jog, Automatic,
Single Block, and Manual Data Input.
Automatic Mode
The automatic mode allows you to run programs. There are ten F func-
tion keys in this mode:
!F1: Quit Automatic mode return to main menu.
!F2. Tool Offset screen. This is where your primary tool offsets are
saved and adjusted.
!F3. Editor: This function is used for creating and editing programs.
!F4. Verification: Allows you to run your program graphically on
screen and verify tool path.
!F5. New File: Enter or remove a program.
!F6. Search: This function allows the operator to run a tool without
starting at the beginning of the program.
!F7. Programming system.
!F8. Disc operations: This mode allows you to erase programs, copy
user files back and forth between hard drive and disc. Communicate
to another computer via RS232 cable.
!F9. Secondary Compensation: Tool nose radius comp and secondary
offsets are stored here.
!F10. Special Functions: Parts counter, saving and loading offsets,
cycle repeat counter, preset feed rates and continuous cycle count-
down.
Active Keys in the Automatic mode
There are many keys that remain active in the Automatic mode. When in
this mode you will see on screen the letter C for Continuous operation of
a program. To make it active you press C on the keypad, to deactivate it
press C again. This is used primarily in bar feed applications.
The letter O is an optional stop. To use this feature you must have the
M01 code in your program where you want it stop. This also activates
and deactivates by pressing O on the keypad.
The front slash key / activates and deactivates the block delete function,
any line of program that you do not choose to run must start with this /.
The S key changes the automatic mode to Single Block allowing each
program line to be executed one at a time, every time the cycle start is
pressed. Pressing A key returns the program back to automatic. Allow-
ing the program to run from start to finish with one press of the cycle
start.

tons. The spindle will start clockwise and run 1000 rpms.
!Type: M05. Press the return key and hit cycle start palm buttons.
The spindle will stop.
Example of moves after tool offsets are entered:
!Type:T1Press the return keyandhitthe cycle start palmbuttons
!Type:X0.Press the return keyandhitthecycle start palm buttons.
!Type:Z1.Press the return keyandhitcycle start palm buttons.
The above to examples are a typical MDI statement. If T1 was a drill it
would be located 1 inch from the face of the work piece and on center
X0.

Single Block
The single block mode will allow the operator to execute a single line of
program code with each press of the palm buttons. This is very useful
for dry running a program and accident prevention
You may initiate the single block mode while on the automatic screen
by pressing the S key. Note: Make sure all your tool offsets are entered
first. After Pressing the Skey press the palm buttons. Look at the screen
the first line of your program will be displayed after the prompt NEXT:
G90G94F300G72.
Hit the palm buttons again and G90G94F300G72 jumps up to the COM-
MAND line. The NEXT prompt will say T1. Hit the palm buttons again
and T1jumps to the COMMAND line and X0 Z0 appears on the NEXT
line.
- NOTE 1: When you run the program for the first time pay CARE-
FUL attention to the NEXT prompt to see were your tools are going.
This will help in preventing a smash up.
- NOTE 2: Use the training program included in this.
