Digital Oscilloscope Errors

When digital oscilloscope errors occur
If an error occurs at the digital oscilloscope, the error detection special relay turns ON, the error code is stored in a special
register, and this appears in the Motion CPU error batch monitor in MT Developer2. The error is not displayed in the error
history. Furthermore, if a self-diagnosis error has occurred, sampling will not be possible. (The cause of this error is also not
detected.)

cause
When the communication load is heavy, while automatically reading the sampling result, the MT Developer2
digital oscilloscope may timeout with the dialogue "reading..." displayed, and cancel reading (communication
error). When this happens, the sampling result can be read manually by [Online]  [Sampling Result File
Operation].
Digital oscilloscope error list
The following table shows the details and cause of errors occurring at the digital oscilloscope, and the corrective action for
those errors.
Error code Error name
0032H Outside settings data
storage range
0033H Settings file write error
0034H SD card unusable
0035H SD memory card writing
not possible
0064H Settings file error
0065H Settings file version not
supported
0096H Sampling results output
error
Error details and cause
A value outside the setting range for the "Sampling
settings storage target" was set when "Sampling
setting RUN request" is ON.
No settings file exists.
Sampling was started with no SD memory card
inserted, or with use of the SD memory card forcibly
stopped.
The SD memory card is write protected.
There is an error in the settings file.
The settings file version is not supported.
The specified drive (memory) capacity or folder/file
configuration is wrong, and therefore it was not
possible to complete sampling results output.

code
Corrective action
Set the "Sampling settings storage target" inside the
range.
Write the settings file again from the digital
oscilloscope.
• Check whether the SD memory card has been
inserted.
• If use of the SD memory card has been forcibly
stopped, release the stop.
Release the SD memory card write protect.
Write the settings file again from the digital
oscilloscope.
Check the versions compatible with the digital
oscilloscope, and write the settings file again.
Delete any unnecessary files, and secure sufficient
memory space.
