 Why subject your robot to a potential sensor failure when you can train a monkey (or a student, if monkeys are lacking) to put the tube at the right height every time? - JVN [more] |

CAN Bus Position Mode problem
Our team is trying to figure out Position mode using CAN Bus, We are following this tutorial and we got the motor to spin, but it does not stop by itself, we have to disable the robot for it to stop. We have changed the PID and all that seams to do is change how fast it get's to top speed. For this we are using 1 CIM motor in a CIMple gear box with a US Digital Encoder EP4 Shaft encoder on the CIMple box. We are using LabVIEW. Any help is greatly appreciated.

Re: CAN Bus Position Mode problem
It sounds like the motor is going the opposite direction that the PID expects. The more it drives the motor the farther it gets from the setpoint, so it speeds up.

Re: CAN Bus Position Mode problem
Ok, thanks for that, I do remember that in we had to invert the position for it to be a positive number... I will pass this on to the rest of the programing team to test it.
