DMC-40x0 Command Reference
BL
FUNCTION:
Reverse Software Limit
DESCRIPTION:
The BL command sets the reverse software limit. If this limit is exceeded during motion, motion
on that axis will decelerate to a stop. Reverse motion beyond this limit is not permitted.
When the reverse software limit is activated, the automatic subroutine #LIMSWI will be executed
if it is included in the program.
ARGUMENTS:
BL n,n,n,n,n,n,n,n
or
BLA=n
where
n is a signed integer in the range -2147483648 to 2147483647. The reverse limit is activated at
the position n-1. The units are in quadrature counts.
n = -2147483648 Turns off the reverse limit.
n = ? Returns the reverse software limit for the specified axes.
