LOOP Command
The block structure of the code lends itself to performing repetitive operations, using the
LOOP command. The command can be used to call a particular labelled block of code for
either a specified number of times or continuously.
An example using the LOOP command is given below, again the START and MAIN code
blocks have been combined within the START block:
1START:
; start label definition
1DECLARE(LOAD)
; declare label
1LIMITS(3,0,0)
; disable limits
1PROFILE3(100,50,4000,35)
; define move parameters
1MI
; set mode to incremental
1LOOP(LOAD,6)
; repeat the load unload 6 times
1END
; end of label definition
1LOAD:
; define program label load
1USE(3)
; use motion profile 3
1O(XX0)
; ensure o/p 3 is off
1T1
; wait for 1 sec delay
1G
; execute move
1O(XX1)
; turn on o/p 3
1T1
; wait for 1 sec delay
1END
; end of label definition
