A
3790H Parameter error
(redundant
function)
• The redundant function module
was mounted next to the control
CPU set to process mode.
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.

37A0H Parameter error
(redundant
function)
• The range set for tracking transfer
in the CPU parameters exceeds
the device range or the file
register capacity set 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 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.

37A1H Parameter error
(redundant
function)
• A device that cannot be used is
specified for tracking transfer 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.

37A2H
37A3H Parameter error
(redundant
function)
• Total amount of data set for
tracking transfer in the CPU
parameters exceeds the
maximum limit.
Stop • Set the tracking capacity of each block
within the allowable range in the CPU
parameters.

37A4H Parameter error
(redundant
function)
• In the CPU module which
operates in redundant mode,
parameters for the unsupported
function have been set or
parameters related to a redundant
system have not been set.
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.

37A5H Parameter error
(redundant
function)
• In the CPU module which
operates in redundant mode, the
nu
mber of device points of the
step relay (S) is set to other than 0
in the device setting of the CPU
parameters.
Stop • Set the number of points of the step
relay (S) to 0 in 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 • 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.
