Fagor alarm 2013: There is no voltage at the I/O 1 board.
CNC 8055 hardware/feedback error (analog axes) · Fagor 8055/8055i
What it means
The 24 V output-supply voltage is absent at I/O expansion board 1. As with the axis board, the CNC drops all enables and stops motion because the machine's interlock signals can no longer be driven. Codes 2014 and 2015 report the same condition on I/O boards 2 and 3; codes 2034/2035 cover I/O boards 4 and 5.
Likely causes
- blown 24 V fuse on the respective I/O board
- missing 24 V from the cabinet supply feeding that board
- loose power connector on the I/O board
- shorted output load dragging the rail down
Triage note: Check which board number the alarm names and verify its dedicated 24 V feed before swapping boards.
