Fault
Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
F043
EMF too high for braking operation
(active in operating states of – –, I, II)
This fault message is activated if the following 5 conditions are fulfilled when a torque direction reversal is requested (selection of
MI or MII):
♦
P272=0 (fault message is parameterized and not alarm + field weakening)
♦
A parameterized, additional, torque-free interval (P160
≠
0) has expired
♦
Parallel drive is ready for engagement of the new torque direction
♦
The absolute value of the armature current (K0118) requested in the new torque direction is >0.5% of P072
♦
The calculated firing angle (K0101) for the armature current requested for the new torque direction is >165 degrees.
Possible fault causes
♦
No “speed-dependent field weakening" (P081=0) is parameterized even though operation in the field weakening range is
needed for the requested maximum speed
Note:
In motor operation, it is possible to reach EMF values corresponding to the peak of the phase-to-phase supply voltage at a
firing angle of
α
G=30° (rectifier stability limit P150) and low armature currents.
♦
Setpoint EMF for field weakening operation too high (parameter P101 is set too high)
♦
Supply voltage dip
♦
EMF controller or field current controller is not optimized, possibly resulting in excessive EMF on power-up.
Fault value:
r047 Index 002 to 016:
Calculated firing angle (armature) before limitation (K0101) i002
Instantaneously
measured actual EMF (K0287)
i003 Armature current controller setpoint (K0118)
F044
A slave connected to the paralleling interface is not operating
(active when U800 = 1 or 2 and U806>10 (master) after receipt of the first valid protocol in operating states – –, I, II)
Fault
value:
1
A fault message is active on a slave
2
A slave is not in operation (e.g. because its enable input is set to "0")
F046
Analog select input for main setpoint (terminals 4 and 5) faulty
(active in operating states of
≤
o6)
This fault message is activated when P700=2 (current input 4 to 20 mA) and an input current of less than 2mA is flowing.
Possible fault causes
♦
Open circuit in supply cable
♦
P700 is incorrectly set
F047
Analog select input 1 (terminals 6 and 7) is faulty
(active in operating states of
≤
o6)
This fault message is activated when P710=2 (current input 4 to 20 mA) and an input current of less than 2mA is flowing.
Possible fault causes
♦
Open circuit in supply cable
♦
P710 is incorrectly set
