9. ERROR CODE LIST
087 BUFFER OVERFLOW When entering data in the memory
by using Reader / Puncher interface,
though the read terminate command
is specified, input is not interrupted
after 10 characters read. I/O unit or
P.C.B. is defective.
090 REFERENCE RETURN
The reference position return cannot
be performed normally because the
reference position return start point
is too close to the reference position
or the speed is too slow. Separate
the start point far enough from the
reference position, or specify a suffi-
ciently fast speed for reference posi-
tion return. Check the program con-
091 REFERENCE RETURN
Manual reference position return
cannot be performed when automat-

092 AXES NOT ON THE

return to the reference position.
093 EXTERNAL SETTING
The reference position external set-

the reference position external set-
ting signal is set to 1 in the following
1) When the jog feed mode (JOG) is
2) When the jog feed mode (JOG) is
selected, however the signal
ZRN is 0.
3) When the emergency stop signal
ESP is 0.
4) When the parameter APC
No.1815 bit 5 is 0.
With an absolute pulse coder, a ref-
erence point is set up even if the ref-
erence point external setting signal
is set to 1 during movement. In this
case, however, axis movement does
not stop even if the reference point is
100 PARAMETER WRITE
On the PARAMETER (SETTING)
screen, PWE (parameter writing en-
