Overview of Alarms
SIMODRIVE alarms
310759 Axis %1 drive %2 bandwidth numerator larger than double blocking
frequency
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: 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
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 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 Clear alarm with the RESET key in all channels. Restart part program.
