A. ALARM LIST
513
Number ContentsMessage
085 COMMUNICATION ERROR When entering data in the memory by using Reader / Puncher interface,
an overrun, parity or framing error was generated. The number of bits
of input data or setting of baud rate or specification No. of I/O unit is in-
correct.
086 DR SIGNAL OFF When entering data in the memory by using Reader / Puncher interface,
the ready signal (DR) of reader / puncher was turned off.
Power supply of I/O unit is off or cable is not connected or a P.C.B. is de-
fective.
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.
088 LAN FILE TRANS ERROR
(CHANNEL–1)
File data transfer via OSI–ETHERNET has been stopped due to a trans-
fer error.
089 LAN FILE TRANS ERROR
(CHANNEL–2)
File data transfer via OSI–ETHERNET has been stopped due to a trans-
fer error.
090 REFERENCE RETURN
INCOMPLETE
1. The reference position return cannot be performed normally be-
cause the reference position return start point is too close to the ref-
erence position or the speed is too slow. Separate the start point far
enough from the reference position, or specify a sufficiently fast
speed for reference position return.
2. During reference position return with the absolute–position detector,
if this alarm occurs even though condition 1 is satisfied, do the fol-
lowing:
After turning the servo motor for the axis at least one turn, turn the
power off and then on again. Then perform reference position re-
turn.
091 REFERENCE RETURN
INCOMPLETE
Manual reference position return cannot be performed when automatic
operation is halted.
092 AXES NOT ON THE REFERENCE
POINT
The commanded axis by G27 (Reference position return check) did not
return to the reference position.
094 P TYPE NOT ALLOWED
(COORD CHG)
P type cannot be specified when the program is restarted. (After the au-
tomatic operation was interrupted, the coordinate system setting opera-
tion was performed.)
Perform the correct operation according to th operator’s manual.
095 P TYPE NOT ALLOWED
(EXT OFS CHG)
P type cannot be specified when the program is restarted. (After the
automatic operation was interrupted, the external workpiece offset
amount changed.)
Perform the correct operation according to th operator’s manual.
096 P TYPE NOT ALLOWED
(WRK OFS CHG)
P type cannot be specified when the program is restarted. (After the au-
tomatic operation was interrupted, the workpiece offset amount
changed.)
Perform the correct operation according to the operator’s manual.
097 P TYPE NOT ALLOWED
(AUTO EXEC)
P type cannot be directed when the program is restarted. (After power
ON, after emergency stop or P / S 94 to 97 reset, no automatic operation
is performed.) Perform automatic operation.
098 G28 FOUND IN SEQUENCE
RETURN
A command of the program restart was specified without the reference
position return operation after power ON or emergency stop, and G28
was found during search.
Perform the reference position return.
099 MDI EXEC NOT ALLOWED
AFT. SEARCH
After completion of search in program restart, a move command is given
with MDI. Move axis before a move command or don’t interrupt MDI op-
eration.
100 PARAMETER WRITE ENABLE On the PARAMETER(SETTING) screen, PWE(parameter writing en-
abled) is set to 1. Set it to 0, then reset the system.
