2.4.3. Dual-Phase Command Configuration
This mode is used with a brushless motor only. In this configuration, the differential
input, pre-amplifier, and self-commutation circuits are bypassed. The dual-phase inputs
are sinusoidal and are 120
°
out of phase from each other. The third phase is generated by
the amplifier. The dual-phase command configuration is shown in Figure 2-9. The
advantage to this configuration is that it provides the smoothest possible motion.
