Acknowledgment: IMMEDIATELY
Cause:
One of the filter natural frequencies is greater than the Shannon frequency.
The Shannon frequency is calculated according to the following formula: 0.5 / current controller sampling time
Fault value (r0949, interpret binary):
Bit 0: Filter 1 (p1658, p1660)
Bit 1: Filter 2 (p1663, p1665)
Bit 2: Filter 3 (p1668, p1670)
Bit 3: Filter 4 (p1673, p1675)
Remedy:
- Reduce the numerator or denominator natural frequency of the current setpoint filter involved.
- Deactivate the filter involved (p1656).

Drive: Speed filter natural frequency > Shannon frequency
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Message value:
%1
Component:
None
Response:
NONE
Acknowledgment: IMMEDIATELY
Cause:
One of the filter natural frequencies is greater than the Shannon frequency.
The Shannon frequency is calculated according to the following formula: 0.5 / speed controller sampling time.
Fault value (r0949, interpret binary):
Bit 0: Filter 1 (p1417, p1419)
Bit 1: Filter 2 (p1423, p1425)
Remedy:
- Reduce the numerator or denominator natural frequency of the speed setpoint filter involved.
- Deactivate the filter involved (p1414).
F07422
Drive: Reference model natural frequency > Shannon frequency
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Message value:
-
Component:
None
Response:
NONE
Acknowledgment: IMMEDIATELY
Cause:
The natural filter frequency of the PT2 element for the reference model (p1433) is greater than the Shannon frequency.
The Shannon frequency is calculated according to the following formula: 0.5 / speed controller sampling time.
Remedy:
- Reduce the natural frequency of PT2 element for reference model (p1433).
F07432
Drive: Motor without overvoltage protection
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Message value:
%1
Component:
None
Response:
OFF2
Acknowledgment: IMMEDIATELY
Cause:
In the case of a fault at maximum speed, the motor can generate an overvoltage that can destroy the converter.
Remedy:
Limit the maximum speed (p1082) without any additional protection.
Note:
The maximum speed is calculated as follows:
p1082 <= 11.695 * DC link voltage overvoltage threshold/r0316
DC link voltage overvoltage threshold:
- Line connection 1 AC: 410 V
- Line connection 3 AC: 820 V
