SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
• The blocking frequency in drive MD 5514: SPEED_FILTER_1_SUPPR_FREQ
• or in drive MD 5210: OUTPUT_VCTRL_FIL_1_SUP_FREQ
• or in drive MD 5213: OUTPUT_VCTRL_FIL_2_SUP_FREQ
• or in drive MD 5268: FFW_FCTRL_FIL_1_SUP_FREQ
• or in drive MD 5288: OUTPUT_FIL_1_SUP_FREQ must be less than the reciprocal
value of two speed controller cycle times MD 5001: SPEEDCTRL_CYCLE_TIME, i.e.
less than 1 / (2 * MD 5001 * 31.25 microsec).
Clear alarm with the RESET key in all channels. Restart part program.
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 fre-
quency from the sampling theorem.
- 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.
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.
Axis %1 drive %2 bandwidth numerator larger than double blocking frequency
%1 = NC axis number
%2 = Drive number
The bandwidth numerator of a speed or manipulated variable setpoint filter is greater than
twice the blocking frequency.
This error message is only issued for the general bandstop filter if:
• Speed filter 1:
• MD 5516 > 0.0 or
• MD 5520 <> 100.0
• Manipulated variable filter 1:
• MD 5212 > 0.0
• Manipulated variable filter 2:
• MD 5215 > 0.0
- 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.
