Basic Programming of OMS controls

Overview

Controlling the behavior of OMS Motion controllers is easily done through an extensive set of intuitive ASCII character commands. The commands are made up of 2 & 3 ASCII characters typically followed by a variable such as a numerical value or control character, such as a ‘?’. In the following command descriptions, a numerical argument is represented by a ‘#’ as a place holder. Each of the commands are terminated by a semicolon ‘;’. Most of the ASCII character commands are intuitive, such as Move Relative = MR#; and due to the vast set of commands some commands are defined with the closest available logical combination. In very basic terms the ASCII commands can be defined in a simple text files consisting of strings of characters sent to the controller. Most any simple application that can send ASCII characters can be used, and OMS Suite offers utilities to control OMS
products.

• AX; (Select the X-axis)
• AC50000; (Set the acceleration)
• VL2500; (Set the maximum velocity)
• MR3000; (Define the Relative Move)
• GO; (Execute the Relative Move)

In a multi-axis move, once the All-Axis mode is defined, the commands are typically the same, however the numerical variables are entered in the defined axis order (X,Y,Z,T,U,V,R,S). To skip an axis just leave the location of that axis blank. A simple multiaxis move where axes X, Y and T (no Z) are defined:

• AA; (Select All Axes)
• AC5000,4000,,6000; (Set accelerations)
• VL800,1000,,4000; (Set velocities)
• MA2222,4444,,5000; (Set Absolute move)
• GO; (Execute Move)
