MDSI Announces Real-Time Software Interface to SERCOS Digital Drives
MDSI announces a real-time software interface to Indramat's SERCOS digital drives
ANN ARBOR, MIManufacturing Data Systems, Inc. (MDSI), today announced
the development of a servo interface to digital drives using SERCOS technology.
MDSI, the developer of OpenCNC® software, the leading unbundled, all-software,
open architecture CNC on the market, developed the interface in collaboration
with Rexroth Indramat, Lohr, Germany, a global manufacturer of servo drives
MDSI's SERCOS digital drive interface is included as a standard feature in
the latest version of MDSI's OpenCNC product, Version 5.0. MDSI's new SERCOS
interface is based on Rexroth Indramat's SoftSERCANS technology, a software-based
SERCOS interface manager. SERCOS (SErial Real-time COmmunications System) is an
open, fiber-optics-based, CNC-to-digital drive interface standard. It was approved
as international standard IEC-61491 in 1995.
Interfacing a completely open, all-software CNC with an open digital
communications standard allows the power and tuning of a servo drive to
be managed entirely in software from a single PC, with just one fiber
optic cable and a passive communication card between the PC and the drive.
The benefit of the OpenCNC SERCOS interface for machine tool builders and
end-user manufacturers is enhanced servo performance, improved part finish,
and the cost savings associated with using standard digital interfaces and
non-hardware-based open solutions for communications to the machine tool
versus using proprietary digital or analog drives.
In an industry dominated by proprietary hardware CNC solutions, MDSI has
proven that high-end, multi-axis CNC machine tools can be controlled entirely
from software-without any motion control cards, proprietary hardware, or
embedded firmware. Although traditional CNC vendors currently tout their own
proprietary, digital drive technologies, customers don't have a choice in
servo systems with those proprietary technologies, says MDSI president
and CEO, James R. Fall.
