What it means
The node reported to the CNC that it has no supply voltage or that its 24 V rail fell below specification. Outputs of that group go dead and motion is inhibited until the feed is restored.
Likely causes
- blown fuse or loose terminal in the 24 V feed to the remote group
- undersized supply collapsing when several outputs switch on together
- corroded ribbon/flat-cable connection between node and its power module
