BL (Backward Limit)
[Setting]
DESCRIPTION:
The BL command sets the reverse software limit. If this limit is exceeded during a commanded motion, the
motion will decelerate to a stop. Reverse motion beyond this limit is not permitted. The reverse limit is
activated at position n-1 count. To disable the reverse limit, set n to -2147483648. The units are in
quadrature counts.
ARGUMENTS: BLx, y, z, w or BLX=x or BL a, b, c, d where
x, y z, w, or a, b, c, d are signed integers
-2147483648 turns off the reverse limit.
USAGE:
