Digital Servo Amplifier Control

June 1, 2005
As the latest in the vendor’s family of motion control products, the Digital MMC mounts directly in an MMC Smart Drive servo amplifier, and controls the amplifier it resides in and up to 15 additional MMC Smart Drive servo amplifiers.

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.
