PMI Regulator Operating Modes
The PMI Regulator’s default operating mode is idle. All other operating modes are
selected by the programmer in the Drive Control register (100/1100). Table 3.1 shows
the available operating modes. Note that the operating modes are mutually exclusive,
i.e., only one mode may be enabled at a time (this is checked by the interlock tests).
The PMI Regulator’s operating modes are shown in figure 3.1 and are described in the
following sections.
