Axis %1 drive %2 natural frequency > Shannon frequency

%1 = NC axis number %2 = Drive number

The natural 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.

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 Clear alarm with the RESET key in all channels. Restart part program.
