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).
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.

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 fil-
ter 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 fre-
quency speed setpoint filter 1)
• Modify MD 1518: $MD_SPEED_FILTER_2_BANDWIDTH (bandwidth speed setpoint fil-
ter 2)
