BL
FUNCTION:
Reverse Software Limit
DESCRIPTION:
The BL command sets the reverse software limit. If this limit is exceeding during motion,
motion on that axis will decelerate to a stop. Reverse motion beyond this limit is not
permitted. The reverse limit is activated at X-1, Y-1, Z-1, W-1. To disable the reverse
limit, set X,Y,Z,W to -2147483648. The units are in quadrature counts.
When the reverse software limit is activated, the automatic subroutine #LIMSWI will be
executed if it is included in the program and a program is executing. See User's Manual,
Automatic Subroutine.
ARGUMENTS:
BL x,y,z,w BLX=x BL a,b,c,d,e,f,g,h
where
x,y,z,w are signed integers in the range -2147483648 to 2147483647.
-214783648 turns off the reverse limit.
"?" returns the reverse software limit for the specified axes.
