jaguar not working

[Bwood16]

Jaguars are showing slow red flashing light when PWM input is supplied and does not run the connected motor. It functioned in the afternoon and does not work anymore. Please reply.

Slow red LED flashing means - Fault condition
See Attached "Getting Started guide"
So, try to replace this one with other.


Also, You can see this forum discution about Jaguar problems:

Or you can directly contact Luminary Micro Support: support@luminarymicro.com

i found this online so i think this will help you:

A slow flashing Red LED indicates that the MDL-BDC detected one of the following fault conditions:
Power supply under-voltage
Over temperature
Over current
Limit switch activated in the current direction of motion

The normally closed limit switch inputs provide a simple method for limiting range of motion. When a limit switch input is open, motor operation in that direction is disabled. Install jumpers if limit switch functionality is not required.

go here if you need more info

Weve had problems with the jaguars and found that if the pwm value is full 1.0 or -1.0 the jaguars may break. so we basically capped our values at 0.99 and -0.99 and we really havent had a problem since

[Bwood16]

we havent tried this yet
and for the sake of getting our robot working we are willing to try
would you mind sending us a link to (or instructions) on how to cap the pwm values?

This i got from the site i mentioned earlier:

CALIBRATION
PROCEDURE
To calibrate the servo-style PWM input for a specific range, connect a PWM source, then:

1. Hold down the USER switch with a straightened paperclip.
2. After 5 seconds, the LED flashes Red and Green to indicate Calibration mode.
3. Instruct the controller to send a full-forward signal.
4. Instruct the controller to send a full-reverse signal.
5. Instruct the controller to return to a neutral signal.
6. The LED will flash Green and Yellow to indicate a successful calibration.
7. Release the USER switch. The MDL-BDC samples these signals and centers the speed range and neutral position between these limits. A calibration failure will be signaled if an out-of-range signal is detected.

We also did. Someone on the forum PM'd me about it after he saw my post when I said we had a problem. I sent it to our head mentor, who may or may not have done something. Judging from their response-the message seemed to be sent personally to our team (me, because I posted our problem)-their support is very good. How'd yours fail? I think I heard something about a blown resistor on ours, but I wonder if it's the same thing as what happened to yours. It would be cool to know, the jaguars have some nice features that might be enabled next year, or later in the future. Although we can't use them now (too late and we only have one left...), it would be nice to work with them on the off-season time.

Hello,

In case this information could be of use on this thread...

To reset the servo-style PWM input on the MDL-BDC Jaguar to the default factory range:
1. Disconnect the power to the MDL-BDC.
2. Hold down the USER switch with a straightened paperclip.
3. Reconnect the power to the MDL-BDC.
4. After a moment, the LED flashes Red and Green slowly to
indicate a successful calibration reset to factory settings.
5. Release the USER switch.

Regards,
Scott

We are having trouble calibrating the speed of our jaguars. We did the calibration steps but it did not set a limit to the speed if the motors. Someone said that they set their PWM values to .99 and -.99. How and where do you set these values?

Bro You Serious??

float limit(float low, float high, float input)
{
if (input < low)
return low;
if(input > high)
return high;
else
return input;
}

just put in -.90 .90 and input is your joystick

I'm looking for an answer in labview if at all possible, not C++
everyone on our team is new to labview so we are stuck on a problem that anyone who is familiar with the system could answer with their eyes closed.

I just noticed something...

The "tom-tech" link mentioned above is not the latest/greatest Getting Started Guide. Please make sure you download it (and recommend downloading it) from the source: http://www.luminarymicro.com/jaguar. (I think another unauthorized link is floating around on the forum somewhere - would appreciate any help notifying me if you stumble across it)

In the meantime, I am trying to contact the folks hosting our doc and take it down/redirect to our site in order to avoid confusion.

Regards,
Scott

I've attached an image of some LabView code that might help. Sounds like you're wanting to saturate your inputs and LabView has a nifty block that will do it for you.

Note: This code isn't complete, I'm only showing the connections dealing with saturation, not the motor references, etc.
