Limit switches input functions

Inputs A1 and A2 have secondary functions as Hard Limit Switch Negative and Hard Limit Switch Positive
respectively. From MotionVew's I/O folder you can select what type of action to perform when one of the
inputs is activated. Refer to the table below for list of possible actions.

Action Description

Not Assigned

No action. Input functioning as regular input

Fault

Input activation cause disable and fault

Stop and Fault

Input activation causes deceleration with rate set by

System Variable QDECEL and then disable and fault



Digital Outputs Control
There are total of 5 outputs. 4 are general purpose programmable and 1 dedicated.
Dedicated output turns ON when system status is READY and cannot be controlled from the program.
The rest of 4 outputs could be assigned special function through MotionView or executing Host Interface
commands. You can turn ON (set) or turn OFF (clear) particular output by writing to corresponding
System Flag or setting particular bit(s) in System Variable OUTPUT. Output can be control by program if
it is not assigned to one of the special functions. In this case, output is controlled internally and changing
its value from within program (or via Host Interface) has no effect on output. Table below summarizes
outputs functions and corresponding flags in DSTATUS System Variables. To set output write to its flag
any non 0 value (TRUE). To clear output write to its flag 0 (FALSE). You also can use flags in expression.
If expression evaluates to TRUE then output will be turned ON. It will be turned OFF otherwise.
Example:
;Following code sets and clears some outputs
;

OUT1 =1

;turn OUT1 ON

OUT2=10

;any value but 0 turns output ON

OUT3=0

;turn OUT3 OFF

OUT2 = APOS>3 && APOS<10

;ON when position within window

;OFF

otherwise
