Tool Offset Parameters
Chapter 22
22-25
Function
Use this parameter to specify the maximum value that a Geometry Radius
Offset may contain. This value represents the absolute maximum value per
table for all tool offsets in that table.
If the operator enters: then:
a positive number greater than the maximum value the control generates the error message:
a negative number less than the negative of the
maximum value
“OFFSET EXCEEDS MAX VALUE”
Refer to your programming and operation manual for more information.
Axis Parameter Number
Single Process Process 1 Process 2
All [249] [20249] [21249]
Range
0.000000 to 390.000000 inches/9906.0000 mm
Notes
For mill and lathe applications, this parameter is global; the value set here
applies to all axes. For dual processing controls, this is a per process
parameter. The value set in the parameters applies to all of the axes
assigned to that process.
