drive MD 5213: OUTPUT_VCTRL_FIL_2_SUP_FREQ or
S
drive MD 5268: FFW_FCTRL_FIL_1_SUP_FREQ or
S
drive MD 5288: OUTPUT_FIL_1_SUP_FREQ
must be lower than the reciprocal of two velocity controller clock cycles in
MD 5001: SPEEDCTRL_CYCLE_TIME, i.e. less than
1/(2*MD 5001*31.25 microsec).
Cancel alarm in all channels by pressing RESET key. Restart the part program.
Axis %1, drive %2 natural frequency > Shannon frequency
%1 = NC axis number
%2 = drive number
The natural frequency of a velocity filter is higher than the Shannon sampling
frequency defined by the sampling theorem.
NC not ready
Switchover for entire channel via MD might be possible.
Channel not ready.
NC Stop in response to alarm.
NC Start disable.
The NC switches to follow-up mode.
Alarm is displayed.
Interface signals are set.
The natural frequency in Hz of a velocity must be less than the reciprocal of two
velocity controller clock cycles.
Velocity filter:
MD 5520 * 0.01 * MD 5514 < 1 / ( 2 * MD 5001 * 31.25 microsec)
