Meaning
The servo is not ON.
• There was a positioning request or other
move reference request in servo OFF sta-
tus.
The servo went OFF during program table
operation.
(Program table operation will be interrupted
while just the step that was being executed
is canceled (If LOOP ≠ 1, the first LOOP is
canceled.))
The servo could not be turned ON within 2
s after turning ON the /S-ON signal or exe-
cuting the SVON command.
• 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)
Error E5BE will occur if there was an alarm
when the servo ON request was sent using
the SVON command. Error E5CE will occur
if the main power supply was OFF when the
servo ON request was sent.
• There was a syntax error in the serial
command.
• There was a number in the serial com-
mand longer than 8 digits or 10 digits.
The specified address was incorrect for a

Corrective Action
Send the move
reference request
only after turning
the servo ON by
turning ON the
/S-ON signal,
setting PnB0E =
0002h so that the
/S-ON signal is
always ON, or
executing the
SVON command.
There are two
possibilities.
• The program
can be can-
celed with the
/PGMRES sig-
nal or PGM-
RES command.
• The servo can
be turned ON
and the pro-
gram can be
restarted with
the /START-
STOP signal or
the START
command.
• Turn the servo
ON when the
motor is
stopped.
• Check the main
power supply.
• Turn ON signals
/HWBB1,
/HWBB2. After
that, temporar-
ily establish the
servo OFF sta-
tus by turning
the /S-ON sig-
nal OFF or
sending the
SVOFF com-
mand, then turn
the servo ON
again.
Check the serial
command's char-
acter string.
Check the
address.
