Siemens SINUMERIK 808D Parameter Manual page 301

Description:
Same meaning as 1st software limit switch plus, however the traversing range
limitation is in the negative direction.
The MD becomes active after reference point approach if the NC/PLC interface signal
DB380x DBX1000.2 (2nd software limit switch minus) is not set.
MD irrelevant:
if axis is not referenced.

NC/PLC interface signal DB380x DBX1000.2 (2nd software limit switch minus)
36110 POS_LIMIT_PLUS
mm, degrees 1st software limit switch plus

Description:
A software limit switch can be activated in addition to the hardware limit switch. The
absolute position in the machine axis system of the positive range limit of each axis
is entered.
The MD is active after reference point approach if NC/PLC interface signal DB380x
DBX1000.3 (2nd software limit switch plus) has not been set.
MD irrelevant:
if axis is not referenced.

NC/PLC interface signal DB380x DBX1000.3 (2nd software limit switch plus)
36120 POS_LIMIT_MINUS2
mm, degrees 2nd software limit switch minus
CTEQ
- -
Description:
Same meaning as 2nd software limit switch plus, but the traversing range limitation is
in the negative direction.
The PLC can select whether software limit switch 1 or 2 is to be active by means of
the interface signal.
For example:
DB380x DBX1000.2 = 0 (1st software limit switch minus) active for 1st axis
DB380x DBX1000.2 = 1 (2nd software limit switch minus) active for 1st axis
MD irrelevant:
if axis is not referenced.

36130 POS_LIMIT_PLUS2
mm, degrees 2nd software limit switch plus
CTEQ
- -
Description:
This machine data can define a 2nd software limit switch position in the positive
direction in the machine axis system. The PLC can select which of the two software
limit switches 1 or 2 is to be active by means of an interface signal.
For example:
DB380x DBX1000.3 = 0 (1st software limit switch plus) active for 1st axis
DB380x DBX1000.3 = 1 (2nd software limit switch plus) active for 1st axis
MD irrelevant:
if axis is not referenced.
