Appendix 5. Table of Conversion Codes for Error Code Output
With this function, the CNC alarms and errors which are normally output to CNC screen are partially
coded and output to PLC I/F device. Thus, the contents of alarms and errors can be confirmed without
CNC screen.
Appendix 5.1 Code Conversion Specifications
The following output will be made when an alarm occurs.
The message displayed in CNC screen is not converted.
(Example) When servo alarm S03 occurs
S03 SERVO WARNING 0052 XZ

The output is as shown above on the CNC screen. However, this can be coded and output to PLC I/F
device as shown below using this function.
Alarm type
··················
Converted into a 2-digit numeral code. (Refer to the section 5.2.)
Alarm message
··········
Not coded, and not output.
Alarm No.
···················
The No. is output as HEX.
Axis name
··················
Error occurrence axis is expressed as a bit, and the bit of servo and
spindle are output separately. The head digit of the alarm without axis
name will be “0”.
The output to PLC I/F device is as follows.

s for the servo axis name and spindle
name, the bit corresponding to the No. of
axis in which the alarm occurs is turned
on.
The max servo axis Nos. in the 1st part
system are 16, and the max spindle Nos.
in the 1st part system are 7. The spindle
alarm is output to the 1st part system.
The PLC axis name is output to the 1st
part system.
