Siemens alarm 26000: Axis %1 clamping monitoring
SINUMERIK 808D alarm · Siemens 808D
What it means
A deliberately clamped axis (interface signal DB380x DBX2.3 'clamping process active') was pushed out of its setpoint position beyond the tolerance in MD36050 $MA_CLAMP_POS_TOL. The NCK reacts with follow-up mode to protect mechanics and workpiece.
Likely causes
- Insufficient clamping pressure on clamped/parked axis
- External force exceeding clamp holding capacity
- MD36050 tolerance set unrealistically small
