Pocket controller with motion and PLC functions

4th Quarter 2015 Electrical switching & drive systems & components

Galil’s DMC-3000 series is a single-axis controller intended for applications such as feed to length and cut machines. It is available as a compact card-level or box-level unit and connects to a stepper or servo motor amplifier of any power range. It can also be purchased with an internal 800 W brushless drive or a stepper drive, which minimises space, cost and wiring. The motion controller can operate standalone or can be controlled by a PC via RS-232 or Ethernet. Drive control signals can be either step and direction or -10/+10 V speed or torque demand signals. Feedback is via an incremental encoder. In addition, an auxiliary encoder input enables the unit to be slaved to a master axis using electronic gearing.

Twin daisy-chainable Ethernet 100 Base-T ports and one 115 kbaud RS-232 port are provided. Ethernet supports multiple masters and slaves. TCP/IP, UDP and Modbus. I/O comprises eight uncommitted, isolated inputs and four isolated outputs. In addition, two uncommitted analogue inputs (0-5 V 12 bit) and one uncommitted analogue output (±10 V,16 bit) are provided. Additional I/O is possible by connecting to a Galil PLC via Ethernet.

Over 200 English-like commands are executable by the controller and include conditional statements and event triggers. The unit supports multi-tasking of up to four threads. Galil provides IDE programs such as Galil Tools, which make programming quick and easy. The controller provides a fast interpreter which avoids the need to compile the program before execution.
