instruction is already used in another
instruction.
2) The interrupt signal device for DVIT instruction
is outside the allowable setting range.
Pulse output number is already used in a
positioning instruction or pulse output instruction
(PLSY, PWM, etc.).

Check servo wiring and parameter setting. Also
check ABS instruction.
Check to make sure the port is not specified by
another instruction.
1) Check to make sure the input (X), as specified
by DSZR, DVIT or ZRN instruction, is not being
used for the following purposes:
- Input interrupt (including the delay function)
- High speed counter C235 to C255
- Pulse catch M8050 to M8057
- SPD instruction
2) Check the contents of D8336 for the correct
interrupt signal specification for DVIT
instruction.
Check to make sure the pulse output destination is
not being driven by another positioning instruction.
The number of times an applied instruction is used
in the program exceeds the specified limit.
Check for the correct attachment of the memory
cassette.
The write-protect switch of the flash memory
cassette was set to ON when data was transferred
to the flash memory.
While data was written in the RUN mode, data was
transferred to (read from or written to) the flash
memory.
Check for the correct connection of extension
cables.
This error occurs in the execution of operation.
• Review the program, or check the contents of
the operands used in the applied instructions.
• Check whether the specified buffer memories
exist in the counterpart equipment.
• Check for the correct connection of extension
cables.
• Check the cable connection between the
programming panel (PP) / programming device
and the PLC.
• Check for the correct connection of extension
cables.
