The offering includes one low voltage power board, three processor boards and the associated
firmware. These four boards as shown on figure 2:
Figure 1-2.
The Atmel Motor Control Interface bus (AMCI bus) shown on
tion between the power board and the processor board; most motor types are supported by this
interface:
The AMCI bus uses three 8 bit connectors and one 8/16 bit connector.
The interface supports up to four phases (U, V, W, X), each with half bridge control and both
voltage and current feedback. With three phase motors, the free X channel can be used for a
brake function.
The interface also supports Hall sensors, speed, temperature and fault signals and also allows
the control of the PFC (Power Factor Correction) from the CPU board. All signals are logic sig-
nals or analog signals scaled to reach the digital Vcc.
• MC300 is the low voltage power board (max 40V).
