4 Introduction

direction, and location of each axis home position are machine dependent. See the machine tool builder’s

manual for more details regarding the actual home position of each axis on the machine.

Manual Pulse Generator (Handwheel)

The manual pulse generator is a 100-pulses-per-revolution incremental-distance jog generator, which

provides a simplified method of incremental feed. The axis to be moved is determined by the position of

the Axis Select switch and the distance that the selected axis is to be moved is determined by which speed

multiply switch is active (pressed, either x1, x10, or x100). Typically, the Advantage 8xx CNC system

will move the below listed incremental distances, but these can be altered by the machine tool builder:

Speed Multiply Position Inch Mode Metric Mode

Low 0.0001 Inch Per Pulse 0.001 Mm Per Pulse

Medium 0.001 Inch Per Pulse 0.01 Mm Per Pulse

High 0.01 Inch Per Pulse 0.1 Mm Per Pulse

MDI (Manual Data Input) Mode Pushbutton

One of the more powerful features of the Advantage 8xx CNC system is the MDI (Manual Data Input)

Mode. When the MDI pushbutton is pressed on the Advantage 8xx CNC system, an MDI editor screen

will appear in the PMAC NC 32 for Windows program. The operator can then enter data into the MDI

editor screen for execution. Unlike most CNC systems, hundreds of lines of G code can be entered into

the MDI editor for execution (up to 32k worth of G code) and the same MDI program can be executed as

many times as needed without retype the G code.

Notes:

Note 1: Before an MDI program can be executed, all machine axes must be home

referenced. If the axes are not home referenced and the operator attempts to

execute an MDI program by pressing the Cycle Start pushbutton, an error

message will appear in the PMAC NC 32 for Windows program informing the

operator that all the axes must be homed before the MDI program can be executed.

Note 2: The last line of any program typed into the MDI editor must be either an

M2 or an M30. By providing either an M2 or M30 on the last line of G code in the

MDI editor, the operator can then execute the G code in the MDI editor as many

times as desired.

Note 3: After typing the desired G code into the MDI editor, the operator must

press the Write To Buffer button at the bottom of the MDI editor to execute the G

code.

Optional Stop Pushbutton

When the Advantage 8xx CNC system is executing a G-code program in either MDI or Auto mode, and

the Optional Stop pushbutton is pressed, it commands the Advantage 8xx CNC system to stop executing

the current G-code program when an M01 (or M1) is encountered in the G-code program. Typical uses

for the Optional Stop (M01 or M1) command includes stopping the machine tool when a tool change is

required in a G-code program on a machine that does not have a tool changer.

Note:

If the G-code program has an M01 (or M1) command entered, and the Optional

Stop pushbutton is not pressed, the Advantage 8xx CNC system will ignore the

M01 (or M1) command and continue to execute the G-code program without

stopping.
