LB
The MDrive Motion Control also offers the user the convenience of naming programs, subroutines and processes to ease in
branching from one part of a program to another, or calling a subroutine.
These labels, once set, will act as pointers to locations in program memory space.
The LB, or Label Instruction, allows the user to assign a 2 character name to a program or branch process within a program or
subroutine.
The restrictions for this command are:
1] A label cannot be named after a MDrive Motion Control Instruction, Variable or Flag.
2] The first character must be alpha, the second character may be alpha-numeric.
3] A label is limited to to characters.
4] A program labeled SU will run on power-up
Please Note: Any program labeled “SU” will execute on power-up.
