Sinumerik Alarm 22052 Channel %1 block %3 spindle %2 no standstill on block change
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
The displayed spindle has been programmed as spindle or as axis even though a positioning operation is still running from the previous block (with SPOSA … spindle positioning beyond block limits). Example: N100 SPOSA  = 100 : N125 S2 = 1000 M2 = 04 ; Error, if spindle S2 from block N100 is still running!
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
Before programming the spindle/axis again using the SPOSA instruction, a WAITS command should be activated in order to wait for the programmed spindle position. Example: N100 SPOSA  = 100 : N125 WAITS (2) N126 S2 = 1000 M2 = 04
Clear alarm with the RESET key. Restart part program
