Acknowledgment: IMMEDIATELY
Cause: One of the 󹪝lt
er natural fr
equencies 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 󹪝lter inv
olved.
- Deactivate the 󹪝lter involved (p1656).

Fault value (r0949, interpret binary):
Bit 0: Filter 1 (p1417, p1419)

Cause: The natural 󹪝lt
er freq
uency 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 / con󹪝guration / commissioning pr
ocedure (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.
No
te:
The maximum speed is calculat
ed 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
