Scalar versus vector
Scalar versus vector
(OP)
Why multimotor AC roller table normally apllies scalar mode control inverter instead of sensorless vector mode control?
Thanks.
Thanks.

RE: Scalar versus vector
It makes any sense to connect an encoder at one of the roller table motors?
RE: Scalar versus vector
If high precision speed control is absolutely necessary, put one motor on a drive all by itself with your encoder feedback for Flux Vector control, then slave the other drive running the rest of the motors from that one. Won't be perfect but better.
If you want near perfectly precise speed control, you would need vector drives on them all and what is called a "line shaft" coordination system. Most high-end vector drives will have that available as a macro.
