300769 Axis %1 drive %2 denominator bandwidth > double natural frequency
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The bandwidth denominator of a current or speed setpoint filter is greater than twice the natural
frequency.
This error message is only issued for the general bandstop filter if:
- Speed setpoint filter 1:
- MD 1516 > 0.0 or
- MD 1520 <> 100.0
- Speed setpoint filter 2:
- MD 1519 > 0.0 or
- MD 1521 <> 100.0
- Current setpoint filter 1:
- MD 1212 > 0.0
- Current setpoint filter 2:
- MD 1215 > 0.0
- Current setpoint filter 3:
- MD 1218 > 0.0
- Current setpoint filter 4:
- MD 1221 > 0.0
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
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: Please inform the authorized personnel/service department.
The bandwidth denominator of a current or speed setpoint filter must be less than twice the natural
frequency.
- Speed setpoint filter 1:
- MD 1515 <= 2 * MD 1514 * 0.01 * MD 1520
- Speed setpoint filter 2:
- MD 1518 <= 2 * MD 1517 * 0.01 * MD 1521
- Current setpoint filter 1:
- MD 1211 <= 2 * MD 1210
- Current setpoint filter 2:
- MD 1214 <= 2 * MD 1213
- Current setpoint filter 3:
- MD 1217 <= 2 * MD 1216
- Current setpoint filter 4:
- MD 1220 <= 2 * MD 1219
- Modify MD 1515: $MD_SPEED_FILTER_1_BANDWIDTH (bandwidth speed setpoint filter 1)
- Modify MD 1514: $MD_SPEED_FILTER_1_SUPPR_FREQ (suppression frequency speed setpoint
filter 1)
- Modify MD 1520: $MD_SPEED_FILTER_1_BS_FREQ (bandstop filter natural frequency speed
setpoint filter 1)
- Modify MD 1518: $MD_SPEED_FILTER_2_BANDWIDTH (bandwidth speed setpoint filter 2)
- Modify MD 1517: $MD_SPEED_FILTER_2_SUPPR_FREQ (suppression frequency speed setpoint
filter 2)
- Modify MD 1521: $MD_SPEED_FILTER_2_BS_FREQ (bandstop filter natural frequency speed
setpoint filter 2)
- Modify MD 1211: $MD_CURRENT_FILTER_1_BANDWIDTH (bandwidth current setpoint filter 1)
- Modify MD 1210: $MD_CURRENT_FILTER_1_SUPPR_FREQ (suppression frequency current
setpoint filter 1)
- Modify MD 1214: $MD_CURRENT_FILTER_2_BANDWIDTH (bandwidth speed setpoint filter 2) 2)
- Modify MD 1213: $MD_CURRENT_FILTER_2_SUPPR_FREQ (suppression frequency current
setpoint filter 2)
- Modify MD 1217: $MD_CURRENT_FILTER_3_BANDWIDTH (bandwidth speed setpoint filter 3) 3)
