Sinumerik Alarm 300907 Axis %1 drive %2 tolerance for safe operational stop exceeded
Parameters:
%1 = Axis number
%2 = Drive number
Definitions:
The drive is disabled via STOP A or STOP B. This blocks the pulses over the relay “Antrieb_IMP”. Request: In monitoring cycle. The actual position has moved too far away from the setpoint/zero position (outside the zero speed window). The zero speed window is parameterized through MD 1330: $MD_SAFE_STANDSTILL_TOL (safe operational stop standstill tolerance).
Reactions:
– Mode group not ready.
– Channel not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
Remedy:
Please inform the authorized personnel/service department. Check the safe standstill tolerance: does the value match the precision and control dynamics of the axis? If not, increase the tolerance.
Program Continuation:
Switch control OFF – ON.
