Considerable ModeAH taking place and stopping (maybe based on low decellaration adjustment) takes a while. Applying STO on drive before the standstill is reached blocks the AxisInterface. PLC reboot, reset_warm clears the interlocked.
Topic is solved in CXA_MotionInterface 220.127.116.11 - released within RM2111_P8. Available on Collaboration-room.
The above mentioned Version is not compatible with RM2203/RM2207.
Placeholder adjustment necessary!
Coming RM2207_P2 includes a corresponding CXAMotionInterface 1.17.x !
Take a look into the release notes for adjusting the placeholder.
