4 Faults and alarms
4.2 List of faults and alarms
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
Component: None
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: - deactivate 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.
Reaction upon N: NONE
Acknowl. upon N: NONE
A07440 EPOS: Jerk time is limited
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None
Reaction: NONE
Acknowledge: NONE
Cause: The calculation of the jerk time Tr = max(p2572, p2573) / p2574 resulted in an excessively high value so that the jerk
time is internally limited to 1000 ms.
Note:
The alarm is also output if jerk limiting is not active.
Remedy: - increase the jerk limiting (p2574).
- reduce maximum acceleration or maximum deceleration (p2572, p2573).
A07441 LR: Save the position offset of the absolute encoder adjustment
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None
Reaction: NONE
Acknowledge: NONE
Cause: The status of the absolute encoder adjustment has changed.
In order to permanently save the determined position offset (p2525) and the determined number of the drive data set
(p2733), they must be saved in a non-volatile fashion (p0971, p0977).
Possible causes:
- motor or encoder were replaced (applies to EQN and DQI).
- position-relevant parameters were changed.
- an encoder that was not adjusted was adjusted (save the project in a non-volatile fashion using "Copy RAM to
ROM").
Note:
This message is not output when switching-on the axis after having first moved it in the switched-off state, as long as
the parameterizable monitoring window was not exited.
Remedy: Readjust the encoder.
