ERROR CODES (SERIAL SPINDLE)
No. LED display Description Countermeasure
000
A parameter that requires power–down has
been specified.
Turn the power off, then back on.
011
The specified feedrate is zero. Check the feedrate parameter specified with a
function code.
013
The specified feedrate (maximum feedrate) is
zero.
Check the value of parameter No.043, which
indicates the maximum feedrate that can be
specified.
070
More than 32 blocks have been registered for a
buffering operation.
Reduce the number of registered blocks to 32.
090
Reference position setting cannot be executed
normally.
Move the tool in the direction of reference posi-
tion return in jog mode at a speed that causes
the servo position error to exceed 128. Then,
specify another reference position setting.
093
A first to third reference position return cannot
be executed because the reference position
has not yet been established.
Set the reference position.
224
The reference position has not yet been estab-
lished. This occurs only when the ZRTN bit of
parameter No.001 is set to 0.
Set the reference position.
250
Input data 1 is invalid. Check input data 1, specified with a function
code.
251
Input data 2 is invalid. Check input data 2, specified with a function
code.
254
A function code or mode is invalid. Check the command code, specified with a
function code. Check the mode.
255
Operation cannot be activated because an in-
valid mode is specified or because block execu-
tion is in progress.
Check the mode. Check whether a block is be-
ing executed.
290
The interface switch signal (DRC) was switched
during block execution.
Switch the signal after block execution stops.
291
The speed of an axial movement specified by an
external pulse has exceeded the upper limit.
This occurs only when the EPEXA bit of param-
eter No.001 is set to 1.
Check the speed specified by the external
pulse. Check the magnification of the external
pulse (parameters No.062 and 063).
292
A checksum error for the non–volatile memory
was detected.
Parameters are cleared. Set the parameters
again. If this alarm subsequently recurs, re-
place the unit.
