If you are not properly communicating with the controller, the program will pause for 3-15 seconds.
The top of the screen will display the message “Status: not connected with Galil motion controller”
and the following error will appear: “STOP - Unable to establish communication with the Galil
controller. A time-out occurred while waiting for a response from the Galil controller.” If this
message appears, you must click OK. In this case, there is most likely an incorrect setting of the serial
communications port. The user must ensure that the correct communication port and baud rate are
specified when attempting to communicate with the controller. Please note that the serial port on the
controller must be set for handshake mode for proper communication with Galil software. The user
must also insure that the proper serial cable is being used, see appendix for pin-out of serial cable.
Once you establish communications, click on the menu for terminal and you will receive a colon
prompt. Communicating with the controller is described in later sections.
Sending Test Commands to the Terminal:
After you connect your terminal, press <carriage return> or the <enter> key on your keyboard. In
response to carriage return (CR), the controller responds with a colon, :
Now type
TPX (CR)
This command directs the controller to return the current position of the X axis. The controller should
respond with a number such as
0000000
The RS232 communication is established.
Step 7. Connect Amplifiers and Encoders.
Once you have established communications between the software and the DMC-1500, you are ready
to connect the rest of the motion control system. The motion control system typically consists of an
ICM-1100 Interface Module, an amplifier for each axis of motion, and a motor to transform the current
from the amplifier into torque for motion. Galil also offers the AMP-11X0 series Interface Modules
which are ICM-1100’s equipped with servo amplifiers for brush type DC motors.
If you are using an ICM-1100, connect the 100-pin ribbon cable to the DMC-1500 and to the
connector located on the AMP-11X0 or ICM-1100 board. The ICM-1100 provides screw terminals
for access to the connections described in the following discussion.
1580
Motion Controllers with more than 4 axes require a second ICM-1100 or AMP-11X0 and second 100-
pin cable.
System connection procedures will depend on system components and motor types. Any combination
of motor types can be used with the DMC-1500.
Here are the first steps for connecting a motion control system:
Step A. Connect the motor to the amplifier with no connection to the controller . Consult the
amplifier documentation for instructions regarding proper connections. Connect and
turn-on the amplifier power supply. If the amplifiers are operating properly, the motor
should stand still even when the amplifiers are powered up.
Step B. Connect the amplifier enable signal.
Before making any connections from the amplifier to the controller, you need to verify
that the ground level of the amplifier is either floating or at the same potential as earth.
WARNING: When the amplifier ground is not isolated from the power line or when it has a different
potential than that of the computer ground, serious damage may result to the computer controller
and amplifier.
