Siemens alarm 61003: No feed programmed in cycle
SINUMERIK function alarm · Siemens 840D/810D powerline
What it means
The cycle was called without a usable feedrate, i.e. the feed parameter evaluates to zero or is missing, so material removal cannot proceed. On lathes without a Y axis in the G18 plane certain feed specifications are also rejected. Correct the feed parameter on the cycle call.
Likely causes
- Feed parameter (e.g. MFR/MRF or F word) omitted or set to zero
- Feed type selection inconsistent with the tool used
- Program branch skips the block that assigns the feed
