fined during
Coordinated
Motion Home of the logical
axis became unde-
fined during axes
group motion or
while decelerating
to a stop. • The command position or
actual position overflowed or
underflowed for a logical axis in
an axes group motion or a logi-
cal axis that was decelerating to
a stop and the home definition
was lost.
• A slave communications error
occurred for a logical axis and
home became undefined during
axes group motion or while
decelerating to a stop.
• A slave for a logical axis left the
network and home became
undefined during axes group
motion or while decelerating to

Opposite
Direction
Limit Input
Detected The limit signal in
the direction oppo-
site to the homing
direction was
detected during a

Negative Limit Input or Opera-
tion Selection at Positive Limit
Input parameter is set to
No

• The location of the homing
input signal sensors, homing
settings, and homing start posi-
tion cause a limit input to be
reached.
