Error storage

When an error occurs, the error detection input turns ON, and the error code corresponding to the error details is stored in the following buffer memory address

(

Axis error No.) for axis error No. storage. Note that there is a delay of up

to 1.8 ms after the error detection signal turns ON until the error code is stored.

Axis No.	Error detection signal	Buffer memory address
1	X8	806
2	X9	906
3	XA	1006
4	XB	1106

A new error code is stored in the buffer memory address ( for axis error storage every time an error occurs.

Types of warnings

(1)Warnings include system warnings and axis 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)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 "

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	Warning type
100 to 199	Common warning
300 to 399	Warning during JOG operation
400 to 499	Warning during manual pulse generator operation
