Servo not working
 

Hello,

I have problem with getting a servo to turn. When I run the example LabVIEW code for a servo, with a voltmeter I see the voltage changing from the PWM pins when I set new positions of the servo. However, when I plug the servo into the PWM slot, it won't move.

Any idea to what's going on and how to fix it?

Thanks in advance.

You have to put a jumper on the side card next to the servo PWM.

Re: Servo not working
 

The servo gets its power from the center pin of the PWM connector. That pin on the Digital Sidecar isn't actually powered until you put a jumper on the "servo power" pins next to it.

We also had this problem, it just needs the jumper as the 2nd poster said.

Yes, a jumper fixed it. Thanks.

Rookie team having the same problem here. Not as hip to all of the lingo, so a pic would be awesome! Thanks

There are plenty of pictures and lots of useful information in the Digital Sidecar documentation.

hi,
i am having the same problem with the servos not working with the servo example codes.

i have jumpers on the 6 volt enable pins across from the PWM pins im using for the servos but i cannot get the servos to work with the code.

the only way i have succsefully made the servos work is using the example code for jaguar motor control with the 6 volt enabled.

i think im just overlooking something simple but if someone could point out what i should do to make this work i would greatly appreciate it.

thanks

Same servo issue for myself...
1) Used Arduino and servos move great...
2) Have jumpered pins in both jumpers beside PWM pins and wired in DSC correctly...

Wind Rriver code...
//member variables
Servo *S1;
Servo *S2;

//in Constructor
S1 = new Servo(6); //Pwm pin 6
S2 = new Servo(10); //pwm pin 10


//when enabled in TeleOperator mode
S1->Set(1.0);
S2->Set(0.5);


....does nothing....
any watch dogs or other lines of code needed for these...
???Something in code is not set or included here???
thoughts or ideas....

tried moving servo over to a Jaguar motor and jumpered but no action...
also tried Victor pin but no help either when jumpered.

Solved when I setup DSC to breakout board using 20A fuse...wired wrong....
before I got 1.1V now I get 6V on this PWM.
