ADT-HC4500 CNC Flame/Plasma Controller

M02

For example (G03):

G92 X0 Y0

G00 X55 Y55

G03 I35

M02

●Current position of cutting gun

○Expected position of cutting gun

Explanation:

I and J are the increment of center at X and Y-axis direction relative to the origin. When you are writing

processing files, if you want to write a circle with a diameter of 100MM, to make it simple you can enter :I50

directly. If the circle diameter is 150MM, you can just enter: I75.

3.6. G04 Pause/Delay instruction

This instruction is used to set the time delay. When the program performs this instruction, it will delay the

stated time. The time unit is in second.

Format: G04 Ln

For example: G04 L3.6 (3.6s delay)

If G04 does not have Ln behind, the system will delay without time limit once G04 is performed until you

press [Start] key.

3.7. G26, G27, G28 Back to reference point

This instruction allows the cutting torch to return to reference point automatically. It runs at travel speed,

the maximum manual speed, which is not controlled by the percentage.

Format:

G26: X axis back to reference point

G27: Y axis back to reference point

G28: X and Y axes back to reference point at the same time

For example: G28 (X and Y axes back to reference point at the same time, equal to run G00)

3.8. G22/G80 cycle processing

This instruction can be used to perform cycle processing. G22 is the beginning of loop, and cycle time L

is appointed. G80 is the end mark of loop. G22 and the nearest G80 below form a loop.

Format: G22 Ln_ (L specifies the cycle times)
