Sinumerik Alarm 310758 Axis %1 drive %2 natural frequency > Shannon frequency
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
The natural 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:
The natural frequency in Hz of a speed setpoint filter must be less than the reciprocal value of two speed controller cycles. Speed filter: MD 5520 * 0.01 * MD 5514 < 1 / ( 2 * MD 5001 * 31.25 microsec) • BSP natural frequency drive MD 5520: SPEED_FILTER_1_BS_FREQ• BSP blocking frequency drive MD 5514: SPEED_FILTER_1_SUPPR_FREQ• Speed controller cycle drive MD 5001: SPEEDCTRL_CYCLE_TIMEProgram Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
