Siemens alarm 22052: [Channel %1: ] Block %3 spindle %2 no standstill on block change
SINUMERIK axis/spindle alarm · Siemens 840D/810D powerline
What it means
At the end of a block the spindle was expected to be at standstill but was still turning (or creeping) beyond the tolerated window. The channel stops because the next block presumes a stationary spindle.
Likely causes
- spindle brake defective or not commanded
- deceleration ramp too soft for the driven mass
- gravity/oil-motor effect turning an unheld vertical spindle
- standstill window/monitoring time parameterized too tightly
