Hi All member,
I had problem on servo amplifier unit Beta sereies(A06B-6093-H113)and P.C.B. had problem is A16B-3200-0290.Our staff found Resister Ceramic ( R3 ) is burn and then they tried to change new one but this servo unit can not run. One case that I think resister that we changed is miss or the the point is not connect.
Do you have any idea? Who had this P.C.B. please let know this resister where are the point of this resistor to connect? ( they had 3 point )

You might want to look further into the circuitry.

Ceramic resistors are usually used when high levels of power need to be resistively dissipated. When/if the resistor is burned, you surely had a MASSIVE current surge/flow which, in all probability, burned/hurt something else in the circuit.

By simply replacing the fried resistor and hoping that the circuit will become resurrected is probably wishful thinking. I'd be inclined to suspect that more parts have been damaged than just the resistor.

Then again, you might be lucky and that's all that got fried - however, I wouldn't count on it....
