DMC digital motion controller from Galil
Digital motion controller

Galil's stand-alone DMC motion controllers can operate without a host computer or they can communicate with the host via RS-232, USB or Ethernet. Various options are available, including enclosure or card styles and single or multi-axis controllers. Several digital controllers can be operated simultaneously per subnet. These should be set up as separately as possible from the office network.

As with all DMC motion controllers, programming is carried out using simple and catchy commands, which always consist of 2 letters (e.g. BG = start). The GDK software supports commissioning with tuning tools, scope, plot, setup and real-time displays of position, inputs/outputs, etc. Drivers are available for Windows, .Net, QNX and Linux.


The DMC-40x0 motion controller is Galil's fastest stand-alone controller. It is part of Galil's latest motion controller family: the Accelera series. It supports encoder input up to 22 MHz, offers servo update rates up to 32 kHz and processes commands within 40 µs - 10 times faster than previous generations.

The DMC-40x0 is a fully featured controller in a compact metal housing with optional controllers. Communication is via RS-232 or Ethernet or the unit operates completely autonomously. The controller includes opto-isolated inputs/outputs and powerful outputs. The latter e.g. for the operation of brakes or relays. Analog inputs for analog sensors are also included in the range of functions. DMC-40x0 controllers and controller unit can be supplied with just one voltage source (20 - 80 VDC). Optionally, the power and control units can also be supplied separately.

The DMC is available with different numbers of axes and each axis can be used by the user for stepper or servo. The standard programming includes PID controllers with feedforward for speed and acceleration, program memory with multitasking for up to 8 programs and unassigned I/Os for synchronization with external events and much more. Movement modes include point-to-point movement, jogging, linear and circular interpolation, contouring, electronic clutch and ECAM.


The Econo series motion controllers are an affordable alternative to the Accelera series and the successor to the DMC-21x3. They are available with or without a housing. The DMC works independently or in connection with a PC via Ethernet 10/100Base-T, RS-232 or USB. In the simplest case, the DMC-41x3 control unit and integrated controller can be supplied with a 20-80 VDC power source. The number of axes can be selected between 1 and 8, and a different drive type can be operated with each axis. The standard programming functions are the same as for the Accelera series. There are only minor differences.
