F06000 fault in Sinamics S120

Hello,

Is it new system or under commissioning?

F06000 - Infeed precharging monitoring time expired.i.e. after infeed power supply line contactor closes, infeed does not signal ready signal within time set in P0857. 

So check, line supply voltage, correct operation of line contactor, line supply voltage setting in p0210 & time set in p0857

HTH

hello,

Sets the monitoring time for the power unit. The following applies for infeeds and drives: The monitoring time is started after an 0/1 edge of the ON/OFF1 command. If the power unit does not return a READY signal within the monitoring time, then fault F06000 (infeeds) or F07802 (drives) is output. For drives, the following also applies: After the pulse enable (operation enabled, p0852), the monitoring time is re-started. If the infeed does not signal ready to the drive within the monitoring time (using BI: p0864 of the drive), fault F07840 is initiated.

The maximum time to pre-charge the DC link is monitored in the power unit and cannot be changed. The maximum duration of the pre-charging depends on the power class and the power unit design. The monitoring time for the pre-charging is started after the ON command (BI: p0840 = 0/1 signal). Fault F30027 is output when the maximum pre-charging duration is exceeded. 

The factory setting for p0857 depends on the power class and the design of the power unit. The monitoring time for the ready signal of the power unit includes the time to pre-charge the DC link and, if relevant, the de-bounce time of the contactors. If an excessively low value is entered into p0857, then after enable, this results in the corresponding fault.
