4.2 List of faults and alarms
F07331 Flying restart: Function not supported
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: It is not possible to power up with the motor rotating (no flying restart).
In the following cases, the "flying restart" function is not supported:
PMSM: operation with U/f characteristic and sensorless vector control.
Note:
PMSM: permanent-magnet synchronous motor
Remedy: De-activate the "flying restart" function (p1200 = 0).
F07404 Drive: DC link voltage monitoring Vdc_max
Message class: DC-link overvoltage (4)
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The monitoring of the DC link voltage p1284 has responded (only U/f control).
Remedy: - check the line supply voltage.
- check the braking module.
- adapt the device supply voltage (p0210).
- adapt the DC link voltage monitoring (p1284).
A07409 (N) Drive: U/f control, current limiting controller active
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: NONE
Cause: The current limiting controller of the U/f control was activated because the current limit was exceeded.
Remedy: The alarm is automatically withdrawn after one of the following measures:
- increase current limit (p0640).
- reduce the load.
- slow down the ramp up to the setpoint speed.
F07410 Drive: Current controller output limited
Message class: Application/technological function faulted (17)
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: The condition "I_act = 0 and Uq_set_1 longer than 16 ms at its limit" is present and can be caused by the following:
- motor not connected or motor contactor open.
- motor data and motor configuration (star-delta) do not match.
- no DC link voltage present.
- power unit defective.
- the "flying restart" function is not activated.
Remedy: - connect the motor or check the motor contactor.
- check the motor parameterization and the connection type (star-delta).
- check the DC link voltage (r0070).
- check the power unit.
- activate the "flying restart" function (p1200).
F07411 Drive: Flux setpoint not reached when building up excitation
Message class: Application/technological function faulted (17)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: When quick magnetizing is configured (p1401.6 = 1) the specified flux setpoint is not reached although 90% of the
maximum current is specified.
- incorrect motor data.
- motor data and motor configuration (star-delta) do not match.
