10-33
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
(r0949): 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 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
(r0949): Bit 0: Filter 1 (p1417, p1419)
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
(r0949): Drive data set number of p0185
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
(r0949): Fault value contains the drive data set number of p0186.
Remedy: The index of the motor data set associated with the drive data set must be entered in p0186.
