12.6 Basic dimensioning
In the following table you will find some basic data to select a drive network. Two examples
show you how to work with the tables.
12.6.1 Conditions
The input powers specified in the tables are only valid if the following requirements for
DC−bus operation are observed:
Basic condition
All feeding points Connection to the three−phase system only via mains chokes specified.
Mains voltage U
mains
= 230 V / 50 Hz U
mains
= 400 V / 50 Hz
Switching frequencies
8200 vector 4 kHz or 8 kHz.
93xx 8 kHz
8200 vector 4 kHz or 8 kHz.
Operating/ambient
temperature max. +40 _C
Motors
(Three−phase asynchronous
motors, asynchronous servo
motors, synchronous servo
motors) The DC−bus system must be dimensioned for a simultaneity factor of F
g
= 1
(All motors operate simultaneously with 100 % power in motor mode)
