[Function] Reset the target value by adding the offset value specified in operand 2 to the original target
value when performing the actuator movement specified in operand 1.
The offset is set in mm, and the effective resolution is 0.001 mm.
A negative offset may be specified as long as the operation range is not exceeded.
An OFST command is processed with respect to soft axes before a BASE shift.
(Note) An OFST command cannot be used outside the applicable program. To use OFST in multiple
programs, the command must be executed in each program.
An OFST command cannot be used with MVPI, MVLI and MVDI commands.
[Example 1] OFST 10 50 Add 50 mm to the specified position of axis 2.
:
OFST 10 0 Return the offset of axis 2 to 0.
[Example 2] The axis pattern can be specified indirectly using a variable.
When the command in [Example 1] is rephrased based on indirect specification using
a variable:
10 (binary)

2 (decimal)
LET 1 2 Assign 2 to variable 1.
OFST *1 50
:
OFST *1 0
[Example 3] LET 2 50 Assign 50 to variable 2.
OFST 1 *2 Add the content of variable 2 (50 mm) to the specified
position of axis1.
