Meaning
• The motor is rotating during servo ON
execution.
• The main power supply went OFF during
servo ON execution.
• Hard wire base block status (HWBB sta-
tus)
The specified setting was incorrect in a
parameter or program table write com-
mand.
The homing method is not specified.
Starting homing was requested by turning
ON the /HOME signal without setting the
homing method.
• There was a request to execute a process
that is not allowed during program table
operation while program table operation
was in progress or on hold.
• There was an attempt to change the pro-
gram table while program table operation
was in progress or on hold.
There was a request that could not be exe-
cuted at the same time as the function that
was being executed.
Example:
There was a request to start program table
operation while the program table was
being initialized.
Homing start was requested (i.e., the /
HOME signal was turned ON) when an
absolute encoder is connected.
An attempt was made to execute a continu-
ous stop under conditions where it could
not be executed.
Examples:
• The coordinates have been set to linear
moving method.
• The immediately-preceding table target
position is not ±INFINITE.
• The immediately-preceding table target
position is ±INFINITE, but the registration
distance is set.
• A value other than 1 has been set for the
execution count.
Continued from previous page.
Corrective Action
• Turn the servo
ON when the
motor is
stopped.
• Turn ON the
/HWBB1 and
/HWBB2 sig-
nals. Then turn
OFF the /S-ON
signal to first
turn OFF the
servo and then
turn ON the
servo again.
Check the set-
ting.
Specify the hom-
ing method with
Pn642 =
n.X.
Request execu-
tion of the pro-
cess again after
canceling pro-
gram table oper-
ation by turning
the
/PGMRES signal
ON.
Execute the
operation again
after the execu-
tion of the current
function is com-
pleted.
• Check the
Encoder.
• Set Pn002 to
n.1 (Use
the absolute
encoder as an
incremental
encoder).
Execute a contin-
uous stop under
conditions where
it can be exe-
cuted.
