A07428 (N) Technology controller parameterizing error
Message class: Error in the parameterization / configuration / commissioning procedure (18)
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: For alarm value = 1:
Set the output limit in p2291 higher than in p2292.

F07435 (N) Drive: Setting the ramp-function generator for sensorless vector control
Message class: Application/technological function faulted (17)
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). An
internal setting command of the ramp-function generator output caused the set setpoint speed to be frozen.
Remedy: - deactivate the holding command for the ramp-function generator (p1141).
- 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).
F07436 (A) Free tec_ctrl 0 actual value limited
Message class: Application/technological function faulted (17)
Reaction: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The actual value for the free technology controller 0 has reached the limit.
The signal source for the actual value is set via connector input p11064.
Fault value (r0949, interpret decimal):
1: The actual value has reached the upper limit.
2: The actual value has reached the lower limit.
Remedy: - adapt the limit settings to the actual value signal (p11067, p11068).
- check the scaling of the actual value signal.
- check the signal source setting for the actual value (p11064).

p11068 (Free tec_ctrl 0 actual value lower limit)
F07437 (A) Free tec_ctrl 1 actual value limited
Message class: Application/technological function faulted (17)
Reaction: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The actual value for the free technology controller 1 has reached the limit.
The signal source for the actual value is set via connector input p11164.
Fault value (r0949, interpret decimal):
1: The actual value has reached the upper limit.
2: The actual value has reached the lower limit.
Remedy: - adapt the limit settings to the actual value signal (p11167, p11168).
- check the scaling of the actual value signal.
- check the signal source setting for the actual value (p11164).
