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.23
( Axis error No.) for axis error No. storage. Note that there is a delay of up
to 3.5 ms after the error detection signal turns ON until the error code is stored.

[2] Warnings
Types of warnings
Warnings detected by the QD75 include system warnings, axis warnings and
warnings detected by servo amplifier.
(1) Warnings include system warnings.
The types of system warnings are shown below.
•
System control data setting warnings
An axis warning for axis 1 will occur.
•
Positioning data setting warnings
An axis warning for each axis will occur.
Note that a warning will occur for the reference axis when an interpolation
designation or axis setting warning occurs.
(2) Warnings include axis warnings.
•
Axis warnings occur due to setting warnings from operations such as
positioning operations, JOG operations or manual pulse generator operations.
•
Axis warnings occur due to system warnings.
The axis operation status does not change even if an axis warning occurs.
