AX12 and connection problem

Are you sure that each servo behaves correctly when connected on its own?

What are the voltages when you do this?

Have you tried a different wire?

Does the PSU on your controller PCB supply enough current (and stably enough) to run the servos? You'll need a minimum of one amp per servo to do things well.

AX12 and connection problem

2009-03-29T23:06:55+01:00

there is another weird thing...

when i connected all 3 servos and checked the voltage (using voltmeter)
i noticed that on the second one is 5.62V. the first one and the last one are ok. next i chanaged the order of servos (switched first one with the second) the problem was still the same - 5.62V on the second connected servo.

sorry for my language... i know it is far from being correct.

AX12 and connection problem

Hi

few days ago i connected 3 of AX12 by my bus cable with controller. unfortunately i changed 'DATA' with 'GND' when i was soldering it to pcb. (yes, i know.. it was very stupid..)

now i have problem using all 3 servos at the same time. when only one is connected all works fine but when i connect two of them, the sencond one has led turned on and both of them seems dead...

i've checked the ID's and the Controll Tables. all looks ok..

plz help me...
