What a great decision you made purchasing a drive system.  Have you been enjoying learning all the different ways the new drive system can benefit your work environment?   After testing the system, you realize that the speed isn’t exactly what you were planning.   Maybe it’s a little too fast or too slow.  Whichever it is, don’t fret, we’ve got you covered.  After reading this and following along, we’ll have your system driving at the perfect speed for your operation.

Let’s start by going over the tools required for a motor speed change.

Your drive system consists of a Roboteq motor controller.  A USB Connector of type B, shown in Figure 1, is needed to connect the motor controller to your computer.

Next, you’ll need to download the Roborun+ Software.  The Roboteq ‘Download Center’ webpage is shown in Figure 2.  The software can be downloaded from the following link:

Now that you have downloaded and gathered all the necessary software and equipment, we can discuss the process for changing the maximum speed of the drive motors.

Step 1: Begin by opening Roborun+.  Figure 3 shows the opening page of Roborun+.

Step 2: Locate your drive system’s USB port and connect the motor controller to your computer using the USB type B cable, shown below in Figure 4.

Step 3: Start by powering up your drive systems.  Then, once the motor controller is found, Roborun+ will prompt you to read the controller configuration, select ’Yes,’ displayed in Figure 5.

Step 4: Locate the ‘Power Output’ section located under the configuration tab.  Expand the ‘Motor 1 Output’ tab, shown below in Figure 6.

Step 5: Under Motor 1, expand the Power Adjust tab showing the Max Power Fwd (%) and Max Power Rev (%), shown below in Figure 7.

Step 6: Adjust the ‘Max Power Fwd (%)’, and the ‘Max Power Rev (%)’ settings as needed.  Reducing the value will reduce the maximum speed for the motor.  It is not recommended to go below 50% without consulting Conceptual Innovation engineers.  Bringing the power level down too low can result in the motor stalling too easily and either burning up the motor or the motor controller.

Step 7: Locate and expand the ‘Motor 2 Output’ tab and make the necessary changes as you did above with Motor 1.

Step 8: After adjustments have been made, select the ‘Save to Controller’ button on the right of the screen, shown in Figure 9.

The profile can also be saved to a disk as a backup by selecting the ‘Save Profile to Disk’ button on the right of the screen.

Step 9: After adjustments have been saved to the motor controller, the changes can be tested and continue to modify and save until your needs are met.  Then remove the USB connection and close the Roborun+ software.  If you have any additional questions remember to check out our other drive system tutorials.  And as always, feel free to contact Conceptual Innovation support team..
