Sinumerik Alarm 300766 Axis %1 drive %2 blocking frequency > Shannon frequency
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
The blocking frequency of a speed setpoint filter is greater than the Shannon sampling frequency from the sampling theorem.
Reactions:
– NC not ready.
– Channel not ready.
– Channel not ready.
– NC Stop on alarm.
– NC Start disable in this channel.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.
Remedy:
Please inform the authorized personnel/service department. Current setpoint filter: The value in MD 1210, 1213,1216 or 1219 must be smaller than the inverse value of two current controller cycles MD 1000: $MD_CURRENTCTRL_CYCLE_TIME (current con- troller cycle) (1/2*MD 1000 *31.25 microsec). Speciality with SINUMERIK 810D: Current setpoint filters 2,3 and 4 are calculated in the speed controller cycle. This means that MD 1213, 1216 or 1219 must be smaller than the inverse value of two speed controller cycles MD 1001: $MD_SPEEDCTRL_CYCLE_TIME (speed controller cycle) (1/2*MD 1001 *31.25 microsec).
Program Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
