4.2 List of faults and alarms
F07300 (A) Drive: Line contactor feedback signal missing
Message value: -
Message class: Auxiliary unit faulted (20)
Drive object: B_INF, VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: - the line contactor was not able to be closed within the time in p0861.
- the line contactor was not able to be opened within the time in p0861.
- the line contactor dropped out during operation
- the line contactor has closed although the drive converter is switched off.
Remedy: - check the setting of p0860.
- check the feedback circuit from the line contactor.
- increase the monitoring time in p0861.

Reaction upon A: NONE
Acknowl. upon A: NONE
F07311 Bypass motor switch
Message value: Fault cause: %1 bin
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Fault value (r0949, interpret bitwise binary):
Bit 1: Switch "Closed" feedback signal missing.
Bit 2: Switch "Open" feedback signal missing.
Bit 3: Switch feedback signal too slow.
After switching, the system waits for the positive feedback signal. If the feedback signal is received later than the
specified time, then a fault trip (shutdown) is issued.
Bit 6: Drive switch feedback signal not consistent with the bypass state.
The drive switch is closed when switching-on or when switching-in the motor.
See also: p1260 (Bypass configuration), r1261 (Bypass control/status word), p1266 (Bypass control command),
p1267 (Bypass changeover source configuration), p1269 (Bypass switch feedback signal), p1274 (Bypass switch
monitoring time)
Remedy: - check the transfer of the feedback signals.
- check the switch.
F07312 Bypass LSS:
Message value: Fault cause: %1 bin
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Fault value (r0949, interpret bitwise binary):
Bit 1: Switch "Closed" feedback signal missing.
Bit 2: Switch "Open" feedback signal missing.
Bit 3: Switch feedback signal too slow.
After switching, the system waits for the positive feedback signal. If the feedback signal is received later than the
specified time, then a fault trip (shutdown) is issued.
Bit 6: Line Side Switch feedback signal not consistent with the bypass state.
When switching-on or when switching-in the motor, the line side switch is closed without this having been requested
from the bypass.
