6SE6400-5CA00-0BP0

Possible Causes 

Fault occurs if one of the three input phases are missed while the pulses are enabled and drive is 
loaded 

Diagnose & Remedy  

Check the input wiring of the mains phases 

Possible Causes 

Fault occurs if the sum of the phase currents is higher than 5 % of the nominal inverter current 

NOTE 
This fault only occurs on inverters that have 3 current sensors (Frame sizes D to F & FX, GX) 

Possible Causes 

That hardware fault (r0947 = 22 and r0949 = 1) caused by the following events: 
(1)  DC-link overcurrent = short circuit of IGBT 
(2)  Short circuit of chopper 
(3) Earth fault 
(4)  I/O board is not properly inserted 

 

Frame sizes A to C (1),(2),(3),(4) 

 

Frame sizes D to E (1),(2),(4) 

 

Frame size F (2),(4) 

Since all these faults are assigned to one signal on the power stack, it is not possible to establish which 
one actually occurred. 
MM440 Frame size FX & GX: 

 

UCE failure was detected, when r0947 = 22 and fault value r0949 = 12 or 13 or 14, depending on 
UCE.  

 

I2C bus read out error, when r0947 = 22 and fault value r0949 = 21 (The power has to be switched 
OFF/ON). 

Diagnose & Remedy  

Check the I/O board. It has to be fully pressed home. 

Possible Causes 

One motor phase is disconnected 

Possible Causes 

Fan no longer working 

Diagnose & Remedy  

 

Fault cannot be masked while options module (AOP or BOP) is connected 

 

Need a new fan 

Possible Causes 

Auto restart attempts exceed value of P1211 

Possible Causes 

Motor data identification failed. 
Fault value =  0:  Load missing 
 

 

1:  Current limit level reached during identification. 

 

 

2:  Identified stator resistance less than 0.1 % or greater than 100 %. 

 

 

3:  Identified rotor resistance less than 0.1 % or greater than 100 %. 

 

 

4:  Identified stator reactance less than 50 % and greater than 500 %
