[About position Compenstation of XY table]

I am a newer in using turbo PMAC motion system, i am a little confused of position compensation.

#2 motor is Y axis, #3 motor is X axis; I want to compensate X and Y axis linearity using laser interferometer and XY perpendicularity at the same time, how to write compensation command?

is the following right?

#3 DEFINE COMP 20,30000

#2 DEFINE COMP 20,30000

#2 DEFINE COMP #3,#2,2,300000
