CHAPTER 8 TROUBLESHOOTING

8.6 Error Code List
Remark
● When a value outside the setting range is written in the following buffer memory areas while in setting mode, the error
code 4
H
is stored. Switching to operation mode without error reset changes the error code to 3
H
. If this
happens, take the corrective action for error code 3
H
.
● Error code priorities are as described below.
When a high-priority error occurs during a low-priority error, the error code of the high-priority error is written over the
error occurrence address.
● Only one error code, as dictated by error priority, is stored in Write data error code (Un\G0). For that reason, when
multiple errors occur, the next error code is stored, even when the error of the stored error code is corrected. Check for
errors other than the stored error code in the parameters of other channels.
