The Correlation Between Servo Drives

- Nov 06, 2018-

1, servo controller through the automatic interface can be very convenient for the operation of the module and Fieldbus module conversion, at the same time using different fieldbus modules to achieve different control modes (RS232, RS485, optical fiber, InterBus, ProfiBus), and the general Inverter control mode is relatively single. 

2, the servo controller directly connected to the rotary transformer or encoder, forming a speed, displacement control closed loop.

And the general frequency converter can only form an open-loop control system.

The control indexes of 3 servo controller (such as steady-state precision and dynamic performance, etc.) are superior to the universal inverter.
