On-line commands I{constant}, M{constant}={expression},
P{constant}={expression}, Q{constant}={expression}
I{constant}=*
Function
Assign factory default value to an I-variable.
Scope
Global
Syntax
I{constant}[..{constant}]=*
where:
• {constant} is an integer from 0 to 1023 representing the number of the I-variable;
• the optional second{constant} must be at least as great as the first {constant} – it
represents the number of the end of the range.
Remarks
This command sets the specified I-variable or range of I-variables to the factor default value.
Each I-variable has its own factory default; these are shown in the I-Variable Specification
section.
Example
I13=*
I100..199=*

INC
Function
Specify Incremental Move Mode
Scope
Coordinate-system specific
Syntax
INC
INC({axis}[,{axis}...])
where:
• {axis} is a letter (X, Y, Z, A, B, C, U, V, W) representing the axis to be specified, or
the character R to specify radial vector mode
Note:
No spaces are permitted in this command.
Remarks
The INC command without arguments causes all subsequent positions for all axes in position
motion commands to be treated as incremental distances. An INC statement with arguments
causes the specified axes to be in incremental mode, and all others stay the way they were
before. The default axis specification is absolute.
If ‘R’ is specified as one of the ‘axes’, the I, J, and K terms of the circular move radius vector
specification will be specified in incremental form (i.e. as a vector from the move start point,
not from the origin). An INC command without any arguments does not affect this vector
specification. The default vector specification is incremental.
If a motion program buffer is open when this command is sent to PMAC, it will be entered
into the buffer as a program statement.
Example
INC(A,B,C) . ; A, B, & C axes made incremental – other axes and rad vector left as is
INC .................... ; All axes made incremental – radius vector left as is
INC(R) ; Radius vector made incremental – all axes left as is
