List of Error Codes
This section lists the codes of errors that may occur in the use of the I/O control module.
The error codes are stored in Latest error code (Un\G100) and also reported to the CPU module.
The
in the error code indicates the number of the multi function counter block where an error has occurred.
Error code
(hexadecimal)
Error name
Description and cause
Operation at the error
Action
3001H
Hardware error
A hardware error has occurred.
The control of hardware logic
stops.
Turn off and on the power, or reset the
CPU module.
If the error occurs again, the possible
cause is a failure of the module.
Please consult your local Mitsubishi
representative.
1060H
Flash ROM data
error
The setting data in the flash ROM are
faulty.
The control can be started with
non-wired hardware logic.
Write the setting data again with a
configuration tool. Take measures to
reduce noise with a shielded cable for
connection.
If the error occurs again, the possible
cause is a failure of the module.
Please consult your local Mitsubishi
representative.
1080H
Number of writes to
a flash ROM over
error
The number of writes to a flash ROM
has exceeded 10000 times.
The control of hardware logic can
be started.
Any further writes to a flash ROM may
not be reflected correctly.
100
H
Multi function
counter block
overflow error
A count value has exceeded the upper
limit value when 32-bit multi function
counter block is set to linear counter
mode.
The count operation stops for the
corresponding multi function
counter block.
Perform the preset function to the
corresponding multi function counter
block.
101
H
Multi function
counter block
underflow error
A count value has fallen below the
lower limit value when 32-bit multi
function counter block is set to linear
counter mode.
The count operation stops for the
corresponding multi function
counter block.
Perform the preset function to the
corresponding multi function counter
block.
1020H
Reset error during
hardware logic
control
Operating condition settings batch-
reset command (Y3) has been turned
on during hardware logic control.
The control of hardware logic
continues.
Stop the control of hardware logic and
turn on Operating condition settings
batch-reset command (Y3).
1040H
Reset error without
any data writes to a
flash ROM
Operating condition settings batch-
reset command (Y3) has been turned
on while any setting data has not been
written to a flash ROM.
The operating condition settings
batch-reset for hardware logic is
not performed.
Set operating conditions in a flash
ROM and turn on Operating condition
settings batch-reset command (Y3).
109
H
SSI encoder block
DATA signal
wire reverse error
The positive and negative of the DATA
signal wire are reversely connected.
Position data from the encoder
cannot be received properly.
Check the external wiring.
10A
H
SSI encoder block
DATA signal
error
The DATA signal input state is Low at
the start of data transmission, or is
High just after the transmission is
completed.
Check the cabling, shielding, SSI
transmission speed, cable length, and
SSI code length. In addition, consider
the possibility of noise effects.
10B
H
SSI encoder block
parity error
A parity error has occurred.
Check the external wiring and settings
of the SSI encoder block.
