6. CABLING AND CONNECTIONS
6.1 Understanding the power unit topology
Figure 9 and Figure 10 show the principles for mains and motor connections of the basic 6-pulse
drive in frame sizes FR10 to FR14.
Some units built in frame size FR11 have double input devices and require an even number of supply
cables but an uneven number of motor cables can be used.
Units built in frame size FR12 consist of two power modules and require an even number of supply
and motor cables. See Figure 9 and the tables in Chapter 6.2.6.
The 12-pulse drives always have a double set of inputs. The motor connection is size dependent as
described above and in Figure 9.
