Which servo drive can run stand alone without PLC.

Motor max speed 6000 rpm. (Except S120).

Hello,

To my knowledge SIMODRIVE 611U can be configured as STANDALONE drive (withput PLC) to control servo motors for speed or positioning application. It has DI/DO as well as AI/AO on board terminal for interface connection. It can be controlled via PROFIBUS with installation of option Profibus module.

Please refer SIMODRIVE 611 universal SIMODRIVE 611 universal E, Control Components for Closed–Loop Speed Control and Positioning  for more detail information.

Also please note, this is discotinued product.

In Sinamics apart from S120, V20, V90 are also available but restrication are like, motor power handling, encoder interface, application etc. etc. & V60 with Sinumerik 808D CNC controller.
