7.2 Switch-on procedures
Switch-on procedure WrA (AFe)
► S1 switches the pre-charging contactor K2 via the coupling relay.
• DC link voltage reaches the pre-set value in parameter LE.04.
• Output O1 is set and switches the interface relay K4.
• K4 disconnects the pre-charging contactor K2 and switches the main contactor K3.
• FurtherchargingoftheDClinkoccursviaK3,WRAorAFEfilter.
By internal programming (OA, IA) the modulation is suppressed as long as
• the adjustable threshold value (LE.04) is reached.
• the waiting time (di.48) has expired.
The control release is set if
► S2 has been set.
• the pre-charging contactor K2 has dropped.
• the main contactor K3 has closed.
• by input I2 the delay time (di.42) has expired.
Following the modulation will be released.

tected.
• The DC link voltage will be regulated to the setpoint (oP.03).
• If the setpoint (oP.03) is reached, the relay output 2 (FLC) switches.
Switch-on procedure Wrb (FU)
► The F5 control board sets the control release by switch (S5).
► With the F6 control board the control release occurs via terminal X2B.1 (STO +).
