F07426 (A) Technology controller actual value limited
Reaction: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The actual value for the technology controller, interconnected via connector input p2264, has reached a limit.
Fault value (r0949, interpret decimal):
1: upper limit reached.
2: lower limit reached.
Remedy: - adapt the limits to the signal level (p2267, p2268).
- Check the actual value normalization (p0595, p0596).
- Deactivate evaluation of the limits (p2252 bit 3)
See also: p0595 (Technological unit selection), p0596 (Technological unit reference quantity), p2264 (Technology
controller actual value), p2267 (Technology controller upper limit actual value), p2268 (Technology controller lower
limit actual value)
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: Re alarm value = 1:
- enable technology controller (p2200).
- set technology controller mode p2251 = 0 (main setpoint).
Re 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: Re alarm value = 1:
Set the output limit in p2291 higher than in p2292.
See also: p2291 (Technology controller maximum limiting), p2292 (Technology controller minimum limiting)
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: - de-activate 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.
