Intelligent, distributed control is ideal for this application and has significantly reduced
the complex wiring in earlier, centrally controlled systems. As stated earlier, each 4-axis
table has its own control cabinet. Motor, power and feedback cables are very short and
connected directly to the Harmonicas. An off-the-shelf, shielded, CAT5E cable is all that
is needed to connect each drive to the CANopen network.
Elmo’s technology allows users to store drive configurations and programs as a portable
application file. Since each axis in this application is identical in terms of the
motor/tuning parameters and the required motion routines, the same file is used for
The Maestro API (application programming interface) provides functions to download the
full application file to all networked drives. During development, this feature was used to
configure and update all of the system’s Harmonicas at once. This capability allows the
customers to also update their entire drive system with the touch of a button!
In the very first system commissioned with Elmo’s motion solution, the simplified wiring
and software setup allowed us to move the system within an hour of applying power!
