A set of default G-codes becomes effective at power up, when the control

is reset,or an emergency stop condition is reset. These default G-codes are

selected by your system installer in AMP. These default G-codes can be

seen on the status display screen after power up or control reset.

This section describes the axis integrand words. Integrand words define
parameters that relate to a specific axis for a canned cycle, probing cycle,

or circular motion block, but they are not limited to these operations. For

example, in circular motion blocks the axis integrands are used to define

the center point of the arc being cut.

Your system installer has the option of assigning either I, J, K, or none as

the axis integrand name for a specific axis. This manual makes the

following assumption:

Integrand Name:

Axis:

K

integrand name for the Z axis

I

integrand name for the X axis

J

integrand name for the C axis

Important: Refer to your system installers documentation to make sure

the assumptions are true. If this assumption is not true, it is all examples

and formats in this manual that use a I, J, or K need to have their letters

replaced with your system installers integrand words accordingly.

The miscellaneous function is designated with an address M followed by a
2- or 3-digit numeric value. Because many of these are set by industry

standards, they are usually referred to as M-codes.

When a miscellaneous function is designated in a block containing axis

motion commands, the control’s PAL program determines whether the

M-codes:

execute at the same time as the axis motion
execute before the axis motion
