To change work coordinate systems, specify the G-code corresponding to
the work coordinate system you want in a program block. Any axis
motion commands in a block that contains a change from one work
coordinate system to another is executed in the work coordinate system
specified in that block.

There are 3 methods to change the value of a work coordinate system zero
point in the work coordinate system table. Two methods can be found in
the following sections:
Method: Chapter:
manually alter the work coordinate system table 3
alter the paramacro system parameter values 5221- 5386 28
