Can not connect to Motion Terminal

We recently purchased a Solo Uno to use for internal testing of BLDC motors. I am attempting to connect to the Solo via USB and control the motor through Motion Terminal.  I am not having any luck connecting to it though.  I have made sure that I am using a "real" USB cable.  I will caveat that I am not a very computer savvy person.

When I power on the controller and connect via the USB cable, my laptop makes a noise indicating that I have plugged something in.  When I click on the plug icon in the upper right corner it turns orange.  I believe it is supposed to be green.

I downloaded the drivers but I do not know how to install them. In Device Manager I do see an alert icon for the driver but when I click on it and tell the system to where to find the driver folder that was downloaded Windows tell me it can't install the driver.

I am using Windows 10 and have the Uno powered with 48 VDC.  Can someone point me in the right direction to get going?  I really need to get my testing started and it looks like this controller will work fine for me if I can just connect to it.

 

Thanks

Clint

Hi @cvail,

some points:

  1. Have you activated the serial API in your browser ( eg. chrome) ? please look at this link to learn how.
  2. To install the USB driver, you need to unzip this file, right-click on the .inf file, and press install.
  3. To work with Motion Terminal you need to make sure SOLO is also powered by an external supply on its inputs, so the SOLO board can not be powered only by connecting the USB cable to it.
  4. The most common problem we see is most users with the similar problems are using USB cables without data lines, so please make sure your USB cable has them ( cables for charging mostly don't have data lines)

I will remain available.

Unfortunately, the above did not change anything.  I know the USB cable has data lines as I use it for uploading files from a digital camera.  Multiple cables do the same thing.

When I click on the plug I get a message that states :   www.solocontrollers.com wants to connect to a serial port   PCI Serial Port (COM3) -Paired

I am powering the Solo with a dedicated 48V 10A power supply.

In my Device Manager under Other Devices there is a warning icon that says Device Firmware Upgrade

 

Does this help?

@cvail ,

You're seeing this because probably you put Pin# 3 of the Piano switch Down, in that case, SOLO goes into DFU mode which is different from Normal operation, the DFU mode is used only when you want to update your firmware.

So here's what you have to do:

  1. Turn OFF SOLO
  2. Put Pin# 3 of the Piano Switch Up (operating in Normal Mode)
  3. Turn ON SOLO
  4. You'll see the E2 LED will start blinking
  5. Now you can connect to SOLO in Motion Terminal

let me know if this was the issue.

Regards
Milad

PS: After connecting to Motion Terminal, please check your "Firmware version" that is visible in the Information panel, if you see the alarm beside it, it means it's not the most updated version, in that case, please get in touch with our team at support[at]solomotorcontrollers.com and they will provide you the updater tool to update the firmware too, the latest firmware has far superior servo driving quality with +/-0.5RPM accuracy.

Thank you.  That seems to have done the trick.  Is there any else I need to know regarding the piano switches to operate the unit via USB?

@cvail , the whole idea is explained in the user manual of SOLO UNO v2 here, especially in the section "Analogue Vs Digital Control" section, but just in case:

- if you are going to use SOLO in Digital Mode through only the motion terminal in a close-loop fashion, you need to keep Pin#5 of the Piano switch always down to stay in closed-loop mode, the rest of the settings in digital mode can be done inside motion terminal ( eg. motor type selection, ...)
