Stepper Motor Operation
To configure the DMC-40x0 for stepper motor operation, the controller requires that the command, MT, must be
given. Further instruction for stepper motor connections are discussed in Step 8c.
Step 2. Install Jumpers on the DMC-40x0
Master Reset and Upgrade Jumpers
JP1 on the main board contains two jumpers, MRST and UPGRD. The MRST jumper is the Master Reset jumper.
When MRST is connected, the controller will perform a master reset upon PC power up or upon the reset input
going low. Whenever the controller has a master reset, all programs, arrays, variables, and motion control
parameters stored in EEPROM will be ERASED.
The UPGRD jumper enables the user to unconditionally update the controller’s firmware. This jumper is not
necessary for firmware updates when the controller is operating normally, but may be necessary in cases of
corrupted EEPROM. EEPROM corruption should never occur, however, it is possible if there is a power fault
during a firmware update. If EEPROM corruption occurs, your controller may not operate properly. In this case,
install the UPGRD Jumper and use the update firmware function on the Galil Terminal to re-load the system
firmware.
Motor Off Jumpers
The state of the motor upon power up may be selected with the placement of a hardware jumper on the controller.
With a jumper installed at the MO location, the controller will be powered up in the “motor off” state. The SH
command will need to be issued in order for the motor to be enabled. With no jumper installed, the controller will
immediately enable the motor upon power up. The MO command will need to be issued to turn the motor off,
unless an error occurs that will turn the motors off. The MO jumper is located on JP1, the same block as the Master
Reset and Upgrade jumpers.
Communications Jumpers for DMC-40x0
The baud rate for RS232 communication can be set with jumpers found on JP1 of the communication board (same
set of jumpers where MO, MRST and UPGD can be found). To set the baud rate to the desired value, see 703HT 2able- below.
19.2 38.4 BAUD RATE
ON ON 9600
ON OFF 19200
OFF ON 38400
OFF OFF 115200
Table 2-1 : Baud Rate Jumper Settings
Other serial communication protocols, such as RS-485, can be implemented as a special - consult Galil.
Step 3. Install the Communications Software
After applying power to the computer, you should install the Galil software that enables communication between the
controller and PC.
Using Windows XP (32 & 64 bit):
Install the Galil Software Products CD-ROM into your CD drive. A Galil .htm page should automatically appear
with links to the software products. Select the correct version of GalilTools software for your particular operating
system and click “Install…” Follow the installation procedure as outlined.
The most recent copy of the GalilTools software can be downloaded from the Galil website.
