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.
Reaction: 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.
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_TIME
Program
Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
