Paramacro Parameters
Chapter 21
21-7
Function
Use this parameter for Type I and II AMP-defined G-codes. AMP-defined
G-code paramacro calls are either modal or non-modal. Use this parameter
for modal macro calls only. Whether an AMP-defined G-code paramacro
call is modal or non-modal is determined by using the parameter TYPE
OF MACRO CALL TO 9010-9019 for Type I or TYPE OF MACRO
CALL 1-15 for Type II.
Modal macro calls mean that the paramacro is automatically called in other
blocks until canceled (similar to the fixed cycles). There are two different
forms of modal paramacro calls. Use this parameter to determine whether
the modal AMP-defined G-code paramacro calls use the modal form that is
associated with the G66 or the G66.1 paramacro calls. Refer to your mill
or lathe programming and operation manuals for more information.
