Error Error name Error details and cause
code
3790H Parameter error • The redundant function module
(redundant was mounted next to the control
function) CPU set to process mode.
37A0H Parameter error • The range set for tracking transfer
(redundant in the CPU parameters exceeds
function) the device range or the file
register capacity set in the CPU
parameters.
37A1H Parameter error • A device that cannot be used is
(redundant specified for tracking transfer in
37A2H
function) the CPU parameters.
37A3H Parameter error • Total amount of data set for
(redundant tracking transfer in the CPU
function) parameters exceeds the
maximum limit.
37A4H Parameter error • In the CPU module which
(redundant operates in redundant mode,
function) parameters for the unsupported
function have been set or
parameters related to a redundant
system have not been set.
37A5H Parameter error • In the CPU module which
(redundant operates in redundant mode, the
function) number of device points of the
step relay (S) is set to other than 0
in the device setting of the CPU
parameters.
37C0H Program error • The program includes an
instruction that cannot be used in
the operation mode set in the
engineering tool.
Stop/ Action
continue
Stop • Set the CPU module to redundant
mode, and restart the system. Or,
remove the redundant function module,
and restart the system. If the same
error code is displayed again, the
possible cause is a hardware failure of
the CPU module. Please consult your
local Mitsubishi representative.
Stop • Check the detailed information
(parameter information) of the error by
executing module diagnostics using
the engineering tool, correct the
parameter setting corresponding to the
displayed number, and take the
following actions:
(1) Check and correct the tracking
transfer settings in the CPU
parameters so that they will be within
the device range or the file register
capacity.
(2) Check and correct the device settings
or the file register capacity setting in
the CPU parameters.
Stop • Check the detailed information
(parameter information) of the error by
executing module diagnostics using
the engineering tool, correct the
parameter setting corresponding to the
displayed number, and write
parameters to the CPU module again.
• Take measures to reduce noise. If the
same error code is displayed again, the
possible cause is a hardware failure of
the CPU module or redundant function
module. Please consult your local
Mitsubishi representative.
Stop • Set the tracking capacity of each block
within the allowable range in the CPU
parameters.
Stop • Check the detailed information
(parameter information) of the error by
executing module diagnostics using
the engineering tool, correct the
parameter setting corresponding to the
displayed number, and write
parameters to the CPU module again.
• Correct the operation mode set in the
engineering tool. If the same error code
is displayed again, the possible cause
is a hardware failure of the CPU
module. Please consult your local
Mitsubishi representative.
Stop • Set the number of points of the step
relay (S) to 0 in the CPU parameters.
Stop • Check the detailed information (error
location information) of the error by
executing module diagnostics using
the engineering tool, display the error
program (step) by clicking the [Error
Jump] button, and delete the program.
Then, write the program to the CPU
module again.
