Overview of Alarms
• Manipulated variable filter 1:
• MD 5212 > 0.0
• Manipulated variable filter 2:
• MD 5215 > 0.0
Reactions:
- 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 bandwidth numerator must be less than twice the blocking frequency.
Speed filter 1:
• BSP bandwidth numerator drive MD 5516: SPEED_FILTER_1_BW_NUMERATOR
• BSP blocking frequency drive MD 5514: SPEED_FILTER_1_SUPPR_FREQ, MD 5516
<= 2 * MD 5514
Manipulated variable filter 1:
• BSP bandwidth numerator drive MD 5212: OUTPUT_VCTRL_FIL_1_BW_NUM
• BSP blocking frequency drive MD 5210: OUTPUT_VCTRL_FIL_1_SUP_FREQ, MD
5212 <= 2 * MD 5210
Manipulated variable filter 2:
• BSP bandwidth numerator drive MD 5215: OUTPUT_VCTRL_FIL_2_BW_NUM
• BSP blocking frequency drive MD 5213: OUTPUT_VCTRL_FIL_2_SUP_FREQ, MD
5215 <= 2 * MD 5213
Program Con-
Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
310760
Axis %1 drive %2 bandwidth denominator greater than double natural frequency
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
The bandwidth denominator of a speed or manipulated variable setpoint filter is greater
than twice the natural 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
Reactions:
- 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 bandwidth denominator of a speed or manipulated variable setpoint filter must be
less than twice the natural frequency.
• Speed filter 1:
• BSP bandwidth drive MD 5515: SPEED_FILTER_1_BANDWIDTH
• BSP blocking frequency drive MD 5514: SPEED_FILTER_1_SUPPR_FREQ
