Ethernet/RS232 Econo Motion Controllers, 1-8 axes

Galil's DMC-21x3 Ethernet motion controllers are designed for extremely cost-sensitive and space-sensitive applications. The DMC-21x3 controllers are available with a variety of plug-in, multi-axis amplifier boards that are designed to eliminate the wiring and any connectivity issues between the controller and drives. Plug-in amplifiers are available for driving stepper, brush and brushless servo motors up to 500 Watts. Or, the DMC-21x3 can be connected to external drives of any power range.

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. It measures just 4.25" x 7.0" for one through four-axis models and 4.25" x 10.75" for five through eight axes. With a 32-bit microcomputer, the DMC-21x3 controllers provide such advanced features as PID compensation with velocity and acceleration feedforward, program memory with multitasking for simultaneously running eight applications programs, and uncommitted I/O for synchronizing motion with external events. Modes of motion include point-to-point positioning, position tracking, jogging, linear and circular interpolation, contouring, electronic gearing and ecam.

Like all Galil controllers, programming the DMC-21x3 is simplified with two-letter, intuitive commands and a full set of software tools such as GalilSuite for servo tuning and analysis.
