Overview
Controller Notation
This command reference is a supplement to the Galil User Manual. For proper controller operation, consult
the Users Manual. This command reference describes commands for Galil Accelera Series Motion
Controller: DMC-40x0. Commands are listed in alphabetical order.
Please note that all commands may not be valid for every controller. To identify the controllers for which
the command is applicable, please review the Usage Section of the command description.
Servo and Stepper Motor Notation:
Your motion controller has been designed to work with both servo and stepper type motors. Installation
and system setup will vary depending upon whether the controller will be used with stepper motors, or
servo motors. To make finding the appropriate instructions faster and easier, icons will be next to any
information that applies exclusively to one type of system. Otherwise, assume that the instructions apply to
all types of systems. The icon legend is shown below.
Attention!: Pertains to servo motor use.
Attention!: Pertains to stepper motor use.
Trippoints
The controller provides several commands that can be used to make logical decisions, or “trippoints,” based
on events during a running program. Such events include: the completion of a specific motion, waiting for
a certain position to be reached, or simply waiting for a certain amount of time to elapse.
When a program is executing on the controller, each program line is executed sequentially. However,
when a trippoint command is executed, the program halts execution of the next line of code until the status
of the trippoint is cleared. Note that the trippoint only halts execution of the thread from which it is
commanded while all other independent threads are unaffected. Additionally, if the trippoint is
commanded from a subroutine, execution of the subroutine, as well as the main thread, is halted.
Since trippoint commands are used as program flow instructions during a running program, they should not
be implemented directly from the command line of the terminal. Sending a trippoint command directly
from the command line might cause an interruption in communications between the host PC and the
controller until the trippoint is cleared.
