Lenze SX-1 - 8. Programming; 8.1 Program Structure

8-8.1 ______
8. Programming
After the Parameters have been entered (See Chapter 7), you may commence program-
rrung.
The Program detines the logical and motion control tunctions to be performed by the
SX-1 . Furthermore, certainvaluesfixedbythe parameters (e. g. velocity, acceleration) may
be moditied by the Program tor individual movements. Such values have priority over the
values fixed by the parameters.
8.1 Program Structure
lt is possible to make an easily-understood Program using only a few instructions trom the
ECL programming language. Main programs can be broken up into subroutines: the
SX-1 can have up to 20 main Programs, each with up to 100 subroutines. lt is possible to
„nest“ subroutines up to 10 deep. Subroutines are „called“ using JMP (jump) instructions:
when the END ot a Subroutine is reached, the Program continues at the calling JMP
in St ructio n.
