4 Faults and alarms
4.2 List of faults and alarms
A07402 (N)
Drive: DC link voltage minimum controller active
Message value:
-
Message class:
Application/technological function faulted (17)
Drive object:
VECTOR_G
Component:
None
Propagation:
GLOBAL
Reaction:
NONE
Acknowledge:
NONE
Cause:
The DC link voltage controller has been activated as the lower switch-in threshold has been undershot (r1246,
r1286).
The kinetic energy of the motor is used to buffer the DC link. The drive is therefore braked.
See also: r0056 (Status word, closed-loop control), p1240 (Vdc controller or Vdc monitoring configuration), p1280
(Vdc controller or Vdc monitoring configuration (U/f))
Remedy:
The alarm disappears when power supply returns.
Reaction upon N:
NONE
Acknowl. upon N:
NONE
F07403 (N, A)
Drive: Lower DC link voltage threshold reached
Message value:
-
Message class:
Infeed faulted (13)
Drive object:
VECTOR_G
Component:
None
Propagation:
GLOBAL
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
Component:
None
Propagation:
GLOBAL
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).
