Siemens alarm 14810: Channel %1 block %2 negative axis speed programmed for positioning axis %3
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
A positioning axis (POS axis, independent of the path) was given a negative axis velocity via its axis-specific feed. Positioning axes require positive speed values; direction comes from the sign of the position, not the feed. Correct the axis feed value.
Likely causes
- Negative FA/axis-feed word on a POS block
- Variable-based axis feed computing negative
- Copy from path-feed logic applied unchanged to positioning axes
