AZIMUTH AXIS SETUP AND CALIBRATION
AZIMUTH SETUP AND CALIBRATION:
1. Connect a straight through DB9 RS232 serial cable to the rear of the RC2800PRKX2SUMC controllers'
"Azimuth" port. Now connect the RS232 serial cable to your laptop or desktop computer being used for setup.
2. Under programs , start the M2 Setup Utility program. Select COM1 in the setup utility under "Rotor Location."
Click "Connect" and once the azimuth control board has been verified, the word "Connected" will appear.
3. Confirm that the either the Azimuth (N-Center) or Azimuth (S-Center) rotator type is selected and that this is
the same port that the serial cable is plugged into on the rear of the control unit. Then verify that the "Pulse
Divisor" is set to the correct value for Azimuth (13200).
4. Using the CCW / DWN or CW / UP buttons on the front of the controller, rotate the Azimuth unit to a known
fixed heading position. This can be any known heading within your specified limit travel area. Note, the actual
digital display heading may not be the actual physical heading of your Azimuth unit at this time, due to your
orientation. Once you are confident that you are physically pointed at your known heading, click the "Set
Heading" button in the setup utility. Enter in the known heading in degrees and then click OK to calibrate your
heading.
USING YOUR AZIMUTH CONFIGURATION WORKSHEET:
5. Using your Axis configuration worksheet, insert both the CCW and CW electronic limits into the setup utility. To
finish this process, click the "Write Settings" button located at the bottom of the utility. At this time, it would be
good to determine the largest sweep of rotation. This is important as you have the choice of setting up either the
CCW or CW hard limit as your "Auto Cal" location. If most of your travel happens to be closer to the CW hard
limit, choose this in the setup utility. If not, we suggest using the CCW hard limit.
6. Based upon your choice from above, press either the CCW or CW button to rotate the azimuth axis until the
motor stops. This will either be your CCW or CW desired electronic limit.
POSITIONING EITHER THE CCW OR CW PHYSICAL LIMIT SCREW:
7. Visually inspect the physical limit switches and limit arm. Activate the limit arm into the limit switch, noting the
location in which the limit arm contacts the wheel of the limit switch. At this point, insert the supplied 8-32 x 1/2"
limit set screw into the hole just outside of the limit arm. This will give you some room between the CCW or CW
electronic limit and the CCW or CW physical limit. This position is not critical other than to give you a reference
point. The controller will calculate absolute distance automatically.
FIND CCW OR CW PHYSICAL LIMIT:
8. Press the "Find Hard Limit" button on the setup utility to start the automatic calibration process. During this
process, the azimuth axis will rotate in either the CCW or CW direction (based upon your initial setup) until it
touches either the CCW or CW physical limit. Note, the azimuth unit will drive through either the CCW or CW
electronic limit, disregarding it during this process. The control box will then calculate the absolute distance
between these two points. This information will automatically be updated in your CCW/DWN or CW/UP limit
switch location.
At this point, you have now establish your reference return point for this axis. The "Auto Cal" can now be used
from either the setup utility, hyper terminal or your own communication software.
