List of Error Codes

Error Error name Cause and description
code
1080H Flash ROM Writing to the flash ROM has been executed more than 25
write number times in a row with the program.
error [Operation of when the error has occurred]
Data is not written to the flash ROM.
17C3H Module The "Extended parameter storage setting" is set to "CPU",
extension and error has occurred while executing module data backup
parameter function or module data initialization function.
writing error [Operation of when the error has occurred]
The module data backup function or the module data
initialization function does not operate.
17C4H The "Extended parameter storage setting" is set to "CPU",
and execute the module data backup function or the module
data initialization function when the CPU module is in the
RUN state.
[Operation of when the error has occurred]
The module data backup function or the module data
initialization function does not operate.
1800H Interrupt factor The value outside the setting range is set in the interrupt
setting error factor setting.
[Operation of when the error has occurred]
The interrupt function does not operate.
1801H Axis No. for The value outside the setting range is set in the axis No. for
interrupt factor interrupt factor.
setting error [Operation of when the error has occurred]
The interrupt function does not operate.
1860H Dedicated The G.ABRST instruction has been executed when the
instruction error value other than 0 is stored in the status. (at the
communication start with a servo amplifier)
[Operation of when the error has occurred]
The positioning function corresponding to each dedicated
instruction is not executed.
1861H The status has been changed during absolute position
restoration (during communication with a servo amplifier) by
the G.ABRST instruction.
[Operation of when the error has occurred]
The positioning function corresponding to each dedicated
instruction is not executed.
1862H The GP.PSTRT instruction has been executed when a
value other than 1 to 600, 7000 to 7004, and 9001 to 9004 is
stored in the start No.
[Operation of when the error has occurred]
The positioning function corresponding to each dedicated
instruction is not executed.
1863H The GP.TEACH instruction has been executed when a
value other than 0 and 1 is set in the teaching data selection.
[Operation of when the error has occurred]
The positioning function corresponding to each dedicated
instruction is not executed.
1864H The GP.TEACH instruction has been executed when a
value other than 1 to 600 is set in the teaching positioning
data No.
[Operation of when the error has occurred]
The positioning function corresponding to each dedicated
instruction is not executed.
1865H The G.ABRST, GP.PSTRT, or GP.TEACH instruction
has been executed with a non-existent axis being specified as
the target of the instruction.
[Operation of when the error has occurred]
The positioning function corresponding to each dedicated
instruction is not executed.
Action
• Correct the program so that writing to the flash ROM is not
executed in a row. (The number of write accesses to the
flash ROM can be checked with [Md.19] No. of write
accesses to flash ROM.)
• If this error has occurred when the module is used correctly,
data can be written after the error is reset, the system is
powered off and on, or the CPU module is reset.
Check the free space on the data memory of the control CPU
and the SD memory card, and execute the module data
backup function or the module data initialization function.
Execute the module data backup function or the module data
initialization function when the CPU module is in the STOP
state.
Correct the value of the interrupt factor setting and turn on
PLC READY signal [Y0].
Correct the value of the axis No. for interrupt factor and turn
on PLC READY signal [Y0].
Set 0 in the status when executing the G.ABRST instruction.

(Instructions, Standard Functions/Function Blocks)
Do not change the status during absolute position restoration
by the G.ABRST instruction. For details, refer to
MELSEC iQ-R Programming Manual (Instructions,
Standard Functions/Function Blocks)
Choose the start number within the setting range when
executing the GP.PSTRT instruction. For details, refer to
MELSEC iQ-R Programming Manual (Instructions,
Standard Functions/Function Blocks)
Set 0 or 1 in the teaching data selection when executing the
GP.TEACH instruction. For details, refer to MELSEC iQ-
R Programming Manual (Instructions, Standard Functions/
Function Blocks)
Set the value within the setting range in the teaching
positioning data No. (1 to 600) when executing the
GP.TEACH instruction. For details, refer to MELSEC iQ-
R Programming Manual (Instructions, Standard Functions/
Function Blocks)
Do not specify a non-existent axis as the target of the
instruction when executing the G.ABRST, GP.PSTRT, or
GP.TEACH instruction. For details, refer to MELSEC iQ-
R Programming Manual (Instructions, Standard Functions/
Function Blocks)
