The amplifiers are daisy chained together with an RJ-45 connection. The field-installable Digital MMC is available in 1-, 2-, 4- and 16-axis versions. The Digital MMC includes 8 DC inputs and 8 DC outputs on board. In addition, the I/O on each drive—8 DC inputs, 4 DC outputs and 1 analog input per drive—is accessible to the application program over the digital network. The Digital MMC can interface to the vendor’s distributed I/O network, and also provides an RS-232/422/485 serial port for connection to an HMI, and built-in 10/100 Ethernet for remote programming, Ethernet HMI, peer-to-peer communication or connection to plant networks or the Internet.
