I often need to change old drivers and I usually change both, driver and motor. I need to now if i can configure new driver to drive old AC servo motor. I now electronics, and I do not have problem to change encoder to be TTL if there is resolver in the motor.
one of many cheap china drivers:
Did anyone make this and what should i looking for. it is usual 170 to 200 Volts motors so this 220V Chines should be ok because i now voltage is not issue if you tune the current correctly. Some of the motors have synchro outputs and some not so one of my question will be if there way to drive this AC motors only with encoder and and AC power UVW and not use synchro.
Any opinion is big value for me

Thank you
