MLFB(6SE70 ... )
MLFB (order number) of the rectifier/regenerating unit
On POWER ON, the "Bootstrap" function is automatically selected as
long as P070 has not been set!
Enter the code of the corresponding MLFB here (see Section 4.3.9.2)

parallel power section connected
x1x to x2x Number of additional
parallel-connected power sections in
feed direction
0xx to 2xx Number of additional
parallel-connected power sections in
recovery direction
The number of parallel feed power sections must be greater than or equal to
the number of parallel recovery power sections:
Permitted configurations: P076= 00x, 01x, 02x, 11x, 12x, 22x
Feed power section(s): E EE EEE EE EEE EEE
Recovery power section(s): R R R RR RR RRR
Correction factor: 1 2 3 1 3/2 1
In recovery direction, calculation of the effective U
d
controller gain and
determination of the effective DC link capacitance for the load current
calculation take the above correction factor into account.
