82 2 Setup
2.1 Set
u
p The default state of Use current reference frame is unchecked. If a
part reference frame has been created before the program is first
recorded Use current reference frame will be automatically
checked.
Programs written prior to SW v2.96.0 do not include the reference
frame that was in place when the program was first recorded. If
Use current reference frame
is unchecked the program will use the
machine reference frame as the initial reference frame when the
program is executed.
If Use machine reference was previously used the same behavior can
be obtained with Use current reference frame.
To obtain the same behavior:
 Select the machine reference frame prior to recording the program
 Uncheck Use current reference frame in the Program Properties
dialog prior to executing the program
or
 Check Use current reference frame
 Select the machine reference frame prior to executing the program
