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.
Axis No.

A new error code is stored in the buffer memory ( Md.33 Axis error No.) for axis
error storage every time an error occurs.
(2) Warnings
Types of warnings
Warnings include system warnings and axis warnings detected by the AD75 and
warnings detected by the servo amplifier.
(1) System warnings are as follows.
•
System control data setting warning ... Axis warning of axis 1.
•
Positioning data setting warning ......... Axis warning of the corresponding axis.
(2) Axis warnings are as follows.
•
Warning that occurred at operation start/during operation such as positioning
operation, JOG operation or manual pulse generator operation.
•
Warning that occurred due to the system warning.
If the axis warning occurs, the axis operation status does not change.
(3) Warnings detected by servo amplifier
These warnings occur due to a hardware fault of the servo amplifier,
servomotor, etc. or when any servo parameter is inadequate.
The servo does not switch OFF depending on the warning, but if it is left as-is,
an error will occur or normal operation will be disabled.
After removing the warning factor, reset the servo amplifier.
