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. Error detection signal Buffer memory address
1 XA 807
2 XB 907
3 XC 1007
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
(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.
(3) Types of warning codes
Warning code Error type
100 to 199 Common warning
300 to 399 Warning during JOG operation
400 to 499 Warning during manual pulse generator operation
500 to 599 Warning during positioning operation
900 to 999 Warning during system control data range check
