Remedy:
Program Continuation:
Axis %1 drive %2 blocking frequency > Shannon frequency
%1 = NC axis number %2 = Drive number
The blocking frequency of a speed setpoint filter is greater than the Shannon sampling frequency from the sampling theorem.
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
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 controller 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).
Clear alarm with the RESET key in all channels. Restart part program.
