Dear We have a problem with the AFE in STS crane, we have AF1, AF2 and AF3 sharing the same Bus DC. When working the 3 AFE there is an increase of the currents only when the STS crane is started, being that the Inverters are not working. We have AF1, AF2 and AFE 3 disconnected from the BUS DC and it happens that AF2 and AFE 3 say FAULT 06, since they exceed the value of the Setpoint (689 Vdc). Each AFE is configured as a slave through the parameter P587 (because I do not know, but it takes more than 5 years so) the problem is that if we change the parameter P587 to master the AFE 1 and AFE 2 work normally arriving at the Set of 689 Vdc. We changed CUSA, IGD, IGBT, PSU2, IVI, VSB and we did not find the problem, we even returned factory values to the CUSA card and loaded the parameters only with the OP1 and it does not work either. In addition we tried to leave the AF1 as master and AF2 and AF3 as slaves but the same thing happens. AF3 as master and AFE 2 and AF1 as Slaves, the system starts to increase the current proportionally reaching up to 700 Amp just when the Crane is switched on. I think the problem is this because in slave mode they exceed the setpoint and in master mode if they reach the setpoint. The AFE 1 as much as slave or master always arrives at slogan of I leave some videos link for more information. https://drive.google.com/open?id=0B4woF_gjpsaucmtRY2Q0N0g5Z0E AFE code: 6SE7041-3EL80-Z Greetings and please some idea.
