11/03
Cause: One of the filter natural frequencies is higher than the Shannon frequency. The Shannon
frequency is calculated according to the following formula: 0.5 / p0115[0].
Fault value Bit 0: Filter 1 (p1658, p1660)
(r0949): 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 affected current setpoint filter.
- Reduce current controller sampling time (p0115[0]).
- Deactivate affected filter (p1656).
Acknowl.: Immediate
F7421
Drive: Speed setpoint filter natural frequency > Shannon frequency
Reaction: NONE
Cause: One of the filter natural frequencies is higher than the Shannon frequency. The Shannon
frequency is calculated according to the following formula: 0.5 / p0115[1].
Fault value Bit 0: Filter 1 (p1417, p1419)
(r0949): Bit 1: Filter 2 (p1423, p1425)
Remedy: - Reduce the numerator or denominator natural frequency of the affected speed setpoint
filter.
- Reduce the speed controller sampling time (p0115[1]).
- Deactivate the affected filter (p1414).
Acknowl.: Immediate
F7422
Drive: Speed controller reference module natural frequency > Shannon frequency
Reaction: NONE
Cause: The filter natural frequency of the PT2 element for the reference model (p1433) is higher
than the Shannon frequency. The Shannon frequency is calculated according to the
following formula: 0.5 / p0115[0].
Remedy: - Reduce natural frequency of PT2 element for reference model (p1433).
- Reduce speed control sampling time (p0115[1]).
Acknowl.: Immediate
F7430
Drive: Converter cannot switch to torque-controlled operation
Reaction: NONE
Cause: When operating in sensorless mode, the converter cannot switch to torque-controlled
operation (BI: p1501).
Remedy: Do not attempt to switch to torque-controlled operation.
Acknowl.: Immediate
F7500
Drive: Power section data set PDS not configured
Reaction: NONE
Cause: For closed-loop I/RF only:
Power section dataset not parameterized, i.e. no data set number entered in the associated
drive data set.
Fault value Drive data set number of p0185
(r0949):
Remedy: The index of the power section data set associated with the drive data set must be entered
in p0185.

Acknowl.: Immediate
F7501
Drive: Motor data set MDS not configured
Reaction: NONE
Cause: For power sections only:
The motor data set has not been configured, e. g. no data set number entered in the
associated drive data set.
Fault value Fault value contains the drive data set number of p0186.
(r0949):
Remedy: The index of the motor data set associated with the drive data set must be entered in p0186.
