3.4 Error Code List
Description and cause
The value obtained by subtracting 1 from the total
value of CH Wave pattern start address setting
and CH Wave pattern data points setting exceeds
89999 (the last buffer memory address of the wave
data registry area).
Multiple channels are set at the same time during
the offset/gain setting.
In the offset/gain setting, "1: Setting channel" is set
for both CH Offset/gain setting mode (offset
specification) and CH Offset/gain setting mode
(gain specification), or "0: Disable" is set.
An invalid value is set to the offset/gain setting. The
number of an error channel cannot be identified.
A value other than -3000 to 3000 is set to Offset/
gain adjustment value specification.
An invalid value is set in CH Offset/gain setting.
The offset value and gain value to be saved in the
flash memory are as follows:
Offset value  Gain value
A value other than 0 and 1 is set in CH Offset/gain
setting mode (offset specification) and CH Offset/
gain setting mode (gain specification).
When the offset and gain are set, a value other than
E or F is set for CH Offset/gain setting mode
(range specification).
The length of the D/A conversion cycle exceeds the
length set in the inter-module synchronization cycle
setting in the system parameter.
The module is set as a synchronization target, and
offset/gain setting mode is set for the operation
mode setting.
As the other cause, a mode switching program has
been executed during the synchronization normal
output mode.
A value other than 0 or 1 is set in Output selection
during a synchronization error.
The module is set as a synchronization target, and
wave output mode is set for the operation mode
setting.
Processing over multiple cycles is detected with the
inter-module synchronization function operating.
Action
Set values in CH Wave pattern start address
setting and CH Wave pattern data points
setting so that the following condition is
satisfied:
"Wave pattern start address setting" + "Wave
pattern data points setting" -1  89999
Correctly set CH Offset/gain setting mode
(offset specification) and CH Offset/gain
setting mode (gain specification).
Perform the offset/gain setting again for all
channels where the user range is set.
If the error occurs again, the possible cause is a
failure of the module. Please consult your local
Mitsubishi representative.
Set a value within the range of -3000 to 3000 to
Offset/gain adjustment value specification.
Start over the offset/gain setting of the channel
where the error has occurred.
If the error occurs again, the possible cause is a
failure of the module. Please consult your local
Mitsubishi representative.
Perform the offset/gain setting again so that the
following condition is satisfied:
Offset value < Gain value
Set CH Offset/gain setting mode (offset
specification) and CH Offset/gain setting
mode (gain specification) to 0 or 1.
Set E or F for CH Offset/gain setting mode
(range specification).
Set a long time in the inter-module
synchronization cycle setting in the system
parameters. As the other way, set unused D/A
conversion enable channels to disable the
conversion so that the following condition is
satisfied:
• Inter-module synchronization cycle setting >
Run time of the inter-module synchronous
interrupt program + D/A conversion time
When using the synchronous normal output
mode, set the operation mode setting to the
normal mode (D/A conversion process).
When performing the offset/gain setting, set the
module as a synchronization non-target in the
system parameters.
In addition, do not execute a mode switching
program during synchronization normal output
mode.
Set a value of 0 or 1 in Output selection during a
synchronization error.
When using the synchronous normal output
mode, set the operation mode setting to the
normal mode (D/A conversion process).
When using wave output mode, set the module
to wave output mode in the system parameters.
Set longer inter-module synchronization cycle
or review the synchronization interrupt program
such as reducing the number of steps.
