A07428 (N) Technology controller parameterizing error
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The technology controller has a parameterizing error.
Alarm value (r2124, interpret decimal):
1:
The upper output limit in p2291 is set lower than the lower output limit in p2292.
Remedy: Re alarm value = 1:
Set the output limit in p2291 higher than in p2292.

F07434 Drive: It is not possible to change the direction of rotation with the pulses enabled
Message value: -
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A drive data set was selected - with the pulses enabled - which has a different parameterized direction of rotation
(p1821).
It is only possible to change the motor direction of rotation using p1821 when the pulses are inhibited.
Remedy: - change over the drive data set with the pulses inhibited.
- ensure that the changeover to a drive data set does not result in the motor direction of rotation being changed (i.e.
for these drive data sets, the same value must be in p1821).

F07435 (N) Drive: Setting the ramp-function generator for sensorless vector control
Message value: Parameter: %1
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: During operation with sensorless vector control (r1407.1) the ramp-function generator was stopped (p1141) or
bypassed (p1122). An internal setting command of the ramp-function generator output caused the set setpoint speed
to be frozen or was not able to be realized.
The drive is switched-on with flying restart activated (p1200), and at the same time the ramp-function generator is
bypassed (p1122).
Remedy: - de-activate the holding command for the ramp-function generator (p1141).
- do not bypass the ramp-function generator (p1122).
- suppress the fault (p2101, p2119). This is necessary if the ramp-function generator is held using jogging and the
speed setpoint is simultaneously inhibited (r0898.6).
Note:
For sensorless vector control it is not practical to read in the main setpoint of the speed control via p1155 or p1160
(p0922). In this case, the main setpoint should be injected before the ramp-function generator (p1070). The reason
for this is that the ramp-function generator output is automatically set when transitioning from closed-loop speed
controlled into open-loop speed controlled operation.
