Servo amplifier was created by tomekw7402
Hello,
I have an ESAB UXD-P 1500 cutting machine, the servo motor controller/amplifier in it recently broke, I need to select a new controller for this machine. The servo is SCT M644/T, the machine is built in such a way that the encoder from the servo is connected to the machine controller, not to the servo driver as in most cases. As I am rather a beginner in this topic, I ask for advice on how to approach such a topic and what amplifier to choose. I will be grateful for any hints.
Thanks,
Tomasz

It needs to be velocity mode servo amplifier, most new drives can be used in velocity mode despite having encoder input, so that is one of the things to check after checking the voltage input and current required.
Pretty sure the motors are low power and if i am not mistaken powered by a 68V torroidal transformer, but do also check that as it was several years since i retrofitted one of those.
