Error storage
When an error occurs, the error detection signal turns ON, and the error code
corresponding to the error details is stored in the following buffer memory address
( Md.33 Axis error No.) for axis error No. storage. Note that there is a delay of up
to 56.8ms after the error detection signal turns ON until the error code is stored.

A new error code is stored in the buffer memory ( Md.33 Axis error No.) for axis
error storage every time an error occurs.
Types of warnings
(1) Warning detection includes system warnings and axis warnings.
The types of system warnings are shown below.
• System control data setting errors
An axis warning for axis 1 will occur.
• Positioning data setting errors
An axis warning for each axis will occur.
Note that a warning will occur for the following axes when an interpolation
designation or axis setting error occurs.
• During axis 1 and axis 2 interpolation control: Axis 1
•
During axis 2 and axis 3 interpolation control: Axis 2
• During axis 3 and axis 1 interpolation control: Axis 3
(2) Axis warnings occur due to setting warnings from operations such as
positioning operations, JOG operations, manual pulse generator operations, or
system errors. They can be canceled by turning ON the " Cd.12 Axis error
reset".
Note that some warnings cannot be canceled unless the cause of the warning
is eliminated.
The axis operation status does not change even if an axis warning occurs.
