(4) System setting errors
Motion CPUs generate a system configuration error under the following
conditions:
Error name
Error code
(Note-1)
Error cause
Check
timing
Operation at
error occurrence
LAY ERROR (SL )
• The slot set in system settings is vacant or a different module is
installed.
AXIS No. MULTIDEF • Duplicate axis No. is set in system settings.
AMP No. SETTING • Not a single axis is set in system settings.
AXIS No. ERROR • System setting data is not written.
I/O POINTS OVER • The number of actual I/O points set in system settings exceeds 256.
ROM ERROR1
• Type of the operating system software of data written to ROM is
different.
ROM ERROR2 • Data is not written to ROM.
• Data size of ROM is abnormal.
ROM ERROR3 ( )
• Execute the ROM writing again.
• Check the adjustment for the version of Motion CPU,
programming system software and operating system
software.
• Data of ROM is abnormal.
ROM ERROR4 ( )
10000
(Note-2)
• Execute the ROM writing again.
• Check the adjustment for the version of Motion CPU,
programming system software and operating system
software.
Cannot be
started.

SP. UNIT LAY
ERROR
2121
• A CPU module is installed in a slot except for a CPU slot or slot 0 to
2.
SP. UNIT LAY
ERROR
2124
(Note-3)
• A module is installed in slot 65 or subsequent slot.
• A module is installed in a base for which "None" is set in base
settings.
SP. UNIT LAY
ERROR
2126
• There are non-installation slots between the CPU modules.
• The modules except for the PLC CPU are installed between the PLC
CPU modules.
PARAMETER ERROR 3010
• The number of CPU modules set in the parameter differ from the
real installation in a Multiple CPU system.
PARAMETER ERROR 3012
• The reference CPU No. set in the parameter differ from the setting in
a Multiple CPU system.
PARAMETER ERROR 3013
Multiple CPU automatic refresh setting is any of the followings in a
Multiple CPU system.
• When a bit device is set as a refreshed, a number except for a
multiple of 16 is set as the refresh first device.
• A non-specifiable device is specified.
• The number of transmitting points is an odd number.
MULTI EXE. ERROR 7010
• A fault CPU is installed in a Multiple CPU system.
• CPUs of unmatched versions are installed in a Multiple CPU system.
(An error is detected at the PLC CPU of function version B.)
• Any CPU No. among CPU No.2 to 4 was reset, after power on a
Multiple CPU system. (This error occurs by the reset CPU No..)

(Note-1) : The error code stored in the diagnosis error area of the self operation information area in the Multiple CPU shared memory.
(Note-2) : When an error code 10000 is displayed, the M2041 ("System setting error" flag) turns ON and an applicable error name shown
above is displayed on the error list monitor of the programming software package.
(Note-3) : Base settings must be performed in System Settings of the Motion CPU even for those bases in which the modules controlled by
the self CPU are not installed.
