Siemens SINAMICS G120X - Drive: Setting Ramp-Function Generator for Sensorless Vector Control; Free Tec_Ctrl 0 Actual Value Limited; Motor Switch-In Alarm; Technology Controller Parameterizing Error

A07427 Motor switch-in alarm
Reaction: NONE
Acknowledge: NONE
Cause: Alarm value (r2124, interpret decimal):
1:
The technology controller is not active or is not being used to control the main setpoint (see p2251).
2:
The operating time limits have been exceeded in at least one external motor.
Remedy: For alarm value = 1:
- enable technology controller (p2200).
- set technology controller mode p2251 = 0 (main setpoint).
For alarm value = 2:
- increase p2381, p2382 or set p2380 = 0.
A07428 (N) Technology controller parameterizing error
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
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
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).

F07437 (A) Free tec_ctrl 1 actual value limited
Reaction: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
