40 ● BL DMC-1400 Series Command Reference
BL
FUNCTION: Reverse Software Limit
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. To disable the
reverse limit, set n 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 the program is executing. See the section on
Automatic Subroutines in the user manual.
ARGUMENTS: BL n where
n is a signed integer in the range -2147483648 to 2147483647.
-214783648 turns off the reverse limit.
USAGE:
While Moving Yes Default Value -214783648
In a Program Yes Default Format Position format
Command Line Yes
Can be Interrogated Yes
Used as an Operand Yes
