Figure 4-8 SPM Power Selector Module with two SPM drives and three motors
Figure 4-7 illustrates configuration 1, which comprises a single SPM Power Selector
Module, two Unidrive SPM power modules and multiple motors. The drive output will be
connected through output motor contactors, which are controlled by the contactor
outputs on the SPM Power Selector Module.
The mode of operation (Master 1 or Master 2), is selected via the master mode select
switch connected between control terminals 4 and 5 of the SPM Power Selector
Module. When the Master Mode Select switch is open (OFF), Master 1 is selected
providing parallel operation of the power modules with Motor M3 connected. When the
switch is closed (ON), Master 2 mode is selected, enabling single module operation of
the power modules with motors M2 and M1 connected.
