Galil's DMC-21x3 Ethernet motion controllers are designed for extremely cost-sensitive and space-sensitive applications. These controllers are typically half-the-price and half-the-size of box-level Ethernet controllers. These intelligent, card-level controllers can be purchased with plug-in, multi-axis ampilfier boards which eliminate wiring between the controller and drives. Amplifier boards are available for driving stepper, brush and brushless servo motors up to 500 Watts. Or, the ICM-20100 break-out board can be used for easy connection to external drives.

The DMC-21x3 series is available in one through eight axis versions and can be configured for control of step or servo motors on any combination of axes. The card-level controller measures just 4.25" x 7.0" for one through four-axis models and 4.25" x 10.75" for five through eight axes. Any mode of motion can be programmed including linear and circular interpolation, contouring, electronic gearing and ecam. As with all Galil controllers, programming the DMC-21x3 is simplified with two-letter, intuitive commands and a full set of software tools such as WSDK for servo tuning and analysis, and the ActiveX Tool Kit for Visual Basic users.
