I've got a problem with RX-28 and RX-64 that really bother me. Followings are the questions that I summerize from the phenomenon:
1 Will the motors produce any noise or signals when the load on the motors are too strong ? If so, will these noise or signal finally affect the 485 bus, so that other motors linked by the 485 bus can't receive the right command ?
2 Do the motors have the ability to protect themselves when they find the signals on the 485 bus are too noisy ? I mean, if the signals on the 485 bus are too bad, will the motors try to reset themselves, ie. the ID and the baudrate to the factory defaults ?
The phenomenon is discribed here. When the robot does motions on the ground (the load will be a little large), the motions are always stuck, and when this happens, then some motors will be automatically resetted. While the robot does motions when hangging in the air (the load will be small), the motions are smooth and nothing unusual happens.
I really wonder your answers soon.
