4 Faults and alarms
4.2 List of faults and alarms
F07403 (N, A) Drive: Lower DC link voltage threshold reached
Message value: -
Message class: Infeed faulted (13)
Drive object: VECTOR_G
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The DC link voltage monitoring is active (p1240 , p1280 = 5, 6) and the lower DC link voltage threshold (r1246,
r1286) was reached in the "Operation" state.
Remedy: - check the line supply voltage.
- check the infeed.
- adapt the device supply voltage (p0210) or the switch-on level (p1245, p1285).
- disable the DC link voltage monitoring (p1240, p1280 = 0).
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F07404 Drive: Upper DC link voltage threshold reached
Message value: -
Message class: DC link overvoltage (4)
Drive object: VECTOR_G
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: - the DC link voltage monitoring is active (p1240 , p1280 = 4, 6) and the upper DC link voltage threshold (r1242,
r1282) was reached in the "Operation" state.
- the monitoring of the DC link voltage p1284 has responded (only U/f control).
Remedy: - check the line supply voltage.
- check the infeed.
- adapt the device supply voltage (p0210).
- if necessary, deactivate the DC link voltage monitoring (p1240, p1280 = 0).
- adapt the monitoring of the DC link voltage (p1284, only U/f).
F07405 (N, A) Drive: Kinetic buffering minimum speed not reached
Message value: -
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: During kinetic buffering the speed fell below minimum speed (p1257 or p1297 for vector drives with U/f control) and
the line supply did not return.
Remedy: Check the speed threshold for the Vdc_min controller (kinetic buffering) (p1257, p1297).
See also: p1257 (Vdc_min controller speed threshold), p1297 (Vdc_min controller speed threshold (U/f))
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F07406 (N, A) Drive: Kinetic buffering maximum time exceeded
Message value: -
Message class: Application / technological function faulted (17)
Drive object: VECTOR_G
Reaction: OFF3 (IASC/DCBRK, NONE, OFF1, OFF2, STOP2)
Acknowledge: IMMEDIATELY
Cause: The maximum buffer time (p1255 and p1295 for vector drives with U/f control) has been exceeded without the line
supply having returned.
