Event name Home Undefined during Coordinated Motion Event code 64590000 hex
Meaning Home of the logical axis became undefined during axes group motion or while decelerating to a stop.
Source Motion Control Function Module Source details Axes group Detection
timing During instruc-
tion execution
Error attributes Level Minor fault Recovery Error reset Log category System
Effects User program Continues. Operation The axes group decelerates to a stop.
System-defined
variables Variable Data type Name
_MC_GRP[*].MFaultLvl.Active BOOL Axes Group Minor Fault Occurrence
Cause and
correction Assumed cause Correction Prevention
The command position or actual posi-
tion overflowed or underflowed for a
logical axis in an axes group motion
or a logical axis that was decelerating
to a stop and the home definition was
lost. Correct the program so that the axis
operates within ranges that do not
cause overflows or underflows in the
command position or actual position. Write the program so that the axis
operates within ranges that do not
cause overflows or underflows in the
command position or actual position.
A slave communications error
occurred for a logical axis and home
became undefined during axes group
motion or while decelerating to a stop. Correct the slave communications
error and define home. None
A slave for a logical axis left the net-
work and home became undefined
during axes group motion or while
decelerating to a stop. Connect the disconnected Slave to
the network again and define home. Do not disconnect slaves for logical
axes from the network during axes
group motions or while decelerating
to a stop.

correction Assumed cause Correction Prevention
The main circuit power of the Servo
Drive was interrupted while the Servo
was ON. Turn ON the main circuit power of the
Servo Drive for the axis where the
error occurred, reset the error, and
then turn ON the Servo. Turn OFF the Servo, then turn OFF
the main circuit power of the Servo
Drive.
