Speed Control for Motor?

[Team 4376]

Is is possible to be able to set a maximum speed for a motor if you are using a button the the ATTACK3 controller to turn a motor on and off?

Hey Team4376,

If you are interested in setting an accurate maximum speed for a motor I would recommend looking at this PID Tutorial:https://decibel.ni.com/content/docs/DOC-14709. You will need to have an encoder on the motor so that you can get feedback to your control system.

Alternatively if you are just looking for some loose limit I would make some logic in your code where if a certain button is pressed instead of scaling your joystick values from -1 to 1 (max and min for the motor VIs) you scale it from -.5 to .5 (or whatever the maximum power you want).  Post back if you have questions.
