Victor motor contorls flashing orange

[thvs]

Hi,
Our victor lights are flashing orange. We have changed the victors and the PWM cables and ensured that everything is wired properly. We were thinking that maybe there was something wrong with the sidecar or the program (labview) that caused the victors to flash orange. The robot was running fine a couple of weeks ago, but we rewired everything, and now it won't run.

What colors should the lights be when running properly?
Can we test to see if there is something wrong with the sidecar?
Is there anything we should be watching for when programming in labview regarding the victors?
Is there any reason, other then no PWM signal, for the light to be flashing orange?

Thanks

According to the datasheets for both the Victor 888 and Victor 884, the Orange flashing LED represents no PWM, and only no PWM. You should check the direction of the PWM and the slot it is plugged into as well as which slot the code wants it plugged into. Also, you should make sure that the sidecar is fully functional with the power LEDs all green, and make sure that the ribbon cable is fully inserted on both ends.
Edit: From the datasheet:
LED Indicator Status
• Green = Full Forward
• Orange = Neutral/Brake
• Red = Full Reverse
• Flashing Orange = no PWM

Hi,
We have checked and everything seems to be in place. When we calibrate the controls they flash green for 2 seconds, then go back to flashing orange. I don't know if that means anything, but I was thinking that meant that there was nothing wrong with the wiring.

Also we got our robot to move by disabling the safety config in the program for the motor controls, However; I don't think that's the right answer.

That tells me the problem is in the code somewhere. Are you using LabVIEW? Are you periodically setting the motor value (i.e. every 100 ms or so)?

It seems like your program isn't updating the motor values when it's at zero. If you are able to calibrate but than it goes back to flashing orange that probably means motorsafety is killing the outputs for some reason.

If you only update the motor values if the joystick value changes, that might result in this type of problem.

Are you establishing all of them as Victors and not as Jaguars in code?

We are using labview. I don't now if we are setting the motor values, how would you check that?

If the problem is with updating motor values, what needs to be changed in the program?

They are established as victors.

Hi Tina,

If I recall you are the rookie team that we helped get going at the 610 quick build?

If that's the case my email to you should help. At the present, I really think that either the PWM cable(s) have been unplugged and or you have not enabled the robot.

I hope the email helps.

BTW.
This is a wonderful place to get help, Chief Delphi that is.

Hi,

We did receive the email, and checked all of the components you stated but the light is still flashing so we are inclined to believe its a programming error. We even had a mechanic and an electrician look at our robot and neither of them could see an error in the wiring.

Do you know of anything we should look for in the program

Thanks

Can you post screen-shots of your Begin.vi Teleop.vi and Finish.vi?

[Alan Anderson]

Everything A lot of what you describe is consistent with an improper PWM cable connection. It takes practice to be able to insert a PWM connector into a Victor properly every time. Unplug one and inspect the pins. They should be perfectly straight. If any are bent, it's likely that it wasn't making proper contact.

Is the dashboard installed, operating and enabled?

LEDs will flash orange until the robot is enabled ... right?

We have been using the basic code, except in the begin VI we changed the safety config to disabled and the Jaguar to a Victor.

It is Flashing orange unless the robot is moving, then there is no color.

Now that sounds like a Victor calibration/joystick centering issue.

The orange flickering light might mean that neutral on the joystick is right at the edge of the Victor's neutral dead zone.
That's not a dangerous condition, just annoying.

With the robot up on blocks can you push the joystick to it's extreme's and see the Victor status light turn green in one direction and red in the opposite direction?
