Control Commands
Commands for controlling the program flow and for structuring the programs. (Group CON)
Command Description Syntax Parameter
CONTINUE continues positioning from point of interrup-
tion, e.g. following a motor-stop CONTINUE –
DELAY time delay DELAY t t = delay in ms
DIM declaration of a global array DIM array [n] array = name
n = number of elements
EXIT desired, premature program termination EXIT –
GOSUB calling up a subroutine GOSUB name name = subroutine name
GOTO jumping within a program GOTO label label = target position
IF THEN conditional program execution IF condition THEN
command condition = branching criteria
… ELSE IF THEN … with conditional alternative branching ELSEIF condition
THEN command command = one or more
program commands
… ELSE … with alternative branching ELSE command
… ENDIF end of the conditional program execution ENDIF
LOOP repeats loop LOOP n label n = number of repetitions
label = target position
MOTOR STOP motor-stop with a programmed delay (with
ramp) MOTOR STOP –
NOWAIT on/off switch for waiting for the command
execution NOWAIT s s = condition ON / OFF
REPEAT beginning of repeat loop REPEAT
REPEAT… UNTIL conditional loop, with an end criteria UNTIL condition condition = abort criteria
SUBMAINPROG commencement of the subroutine definition
area SUBMAINPROG –
… ENDPROG end of the subroutine definition area ENDPROG –
SUBPROG begins a subroutine SUBPROG name name = subroutine name
… RETURN ends a subroutine RETURN –
SYSVAR system variable (pseudo array) reads system
values SYSVAR [n] n = index
VLTALARMSTAT returns if an alarm is active or not VLTALARMSTAT –
VLTCONTROL sets the VLT control word in MOTOR OFF state VLTCONTROL
control word value
value
VLTERRCLR clears a VLT-alarm VLTERRCLR –
WAITAX waits until target position is reached WAITAX –
WAITI waits for input WAITI n s n = input number
s = expected ON / OFF
WAITNDX waits until the next index position is reached WAITNDX t t = timeout in ms
WAITP waits until a certain position is reached WAITP p p = absolute position
WAITT time delay in milliseconds WAITT t t = delay in ms
WHILE … DO conditional loop with commencement criteria WHILE condition DO condition = abort criteria
ENDWHILE end of the loop ENDWHILE –
