Hello all
I have an Arduino-Board which sends the commands to the Trex Jr. The Trex controls one Motor without encoder.
The problem is now that, when I block the Motor the Trex Jr stop to send PWM-signals to the motors. This is happen with a current of 1 A to 2 A and the current limit is about 5 A (current limit parameter = 60) appointed.
I use the Trex Jr in the joint mode.
I also tried this experiment without a current limit and the same thing happens…
I could exclude that its cause of the Arduino, it happens even when I send a constant signal.
I tested different things:
- I blocked the Motor and gave only few power. The Motor stopped with less than 1 A current.
- I blocked the Motor and gave full power. The Motor stopped with more than 2 A current.
- I increased the friction. So the Motor could turn but had a big torque. The Motor Stopped with a current between 1A and 2 A.
Thanks for the support
