UMC780125-03 Servo driver
The difference between servo drive and inverter is mainly reflected in the following aspects:
Overload capacity: The servo drive generally has 3 times the overload capacity, which can be used to overcome the inertia moment of the inertial load at the start of the moment, while the inverter generally allows 1.5 times the overload.
Control accuracy: The control accuracy of the servo system is much higher than the frequency conversion, and the control accuracy of the servo motor is usually guaranteed by the rotary encoder at the back of the motor shaft.
Application: The former belongs to the field of drive control, the latter belongs to the field of motion control. Servo drives are usually used in the pursuit of high precision, high performance, high response occasions, while the frequency converter is more suitable for general industrial applications, the performance index requirements are not high application occasions.
