Faults and Alarms
List of Faults and Alarms
A07416 Drive: Flux controller configuration
Reaction: NONE
Acknowledge: NONE
Cause: The configuration of the flux control (p1401) is contradictory.
Alarm value (r2124, interpret hexadecimal):
ccbbaaaa hex
aaaa = Parameter
bb = Index
cc = fault cause
1: Quick magnetizing (p1401.6) for soft starting (p1401.0).
3: Quick magnetizing (p1401.6) for Rs identification after restart (p0621 = 2).
Remedy: Re fault cause = 1:
- Shut down soft start (p1401.0 = 0).
- Shut down quick magnetizing (p1401.6 = 0).
Re fault cause = 3:
- Re-parameterize Rs identification (p0621 = 0, 1)
- Shut down quick magnetizing (p1401.6 = 0).
F07426 (A) Technology controller actual value limited
Reaction: OFF1 (IASC/DCBRAKE, 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, decimal interpretation):
1: upper limit reached.
2: lower limit reached.
Remedy: - adapt the limits to the signal level (p2267, p2268).
- check the scaling of the actual value (p2264).

(Technology controller lower limit actual value)
F07435 (N) Drive: Setting the ramp-function generator for sensorless vector control
Reaction: OFF2 (IASC/DCBRAKE, 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).
F07439 Drive: Higher current controller dynamic performance not possible
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The function "Current controller dynamics higher" (p1810.11 = 1) is selected, however is not supported by the power
unit (r0192.27 = 0) or by the safety technology without encoder (9506 = 1).
Fault value (r0949, decimal interpretation):
1:
- firmware of the booksize power unit is not up-to-date.
- blocksize or S120 combi power unit was used.
2:
- a sine-cosine encoder with encoderless safety technology is used.
Remedy: In general:
- Deselect the function "Current controller dynamics higher" (p1810.11 = 0) and if required, set the current, speed
and position controller again or calculate (p0340 = 4).
For fault value = 1:
- If necessary, upgrade the firmware of the booksize power unit to a later version (version >= 4.4).
- Use a booksize power unit (version >= 4.4).
For fault value = 2:
- Re-parameterize encoderless safety technology (9506 = 1) to safety technology with an encoder (p9506 = 0).
