High-capacity AC servo amp VF66SV


From hydraulic to electric servo--A revolution in the structure of industrial machinery. Welcome to the world of high-capacity servos.


VF66SV servo amp with built-in high precision positioning function

Speed control range of 1 to 10,000
The combination of a servo motor and high-resolution encoder enables a speed control rate of 1 to 10,000 using real number operations.

25-bit angle/position control
A high-resolution angle control/position control of 33,554,432 p/r is achieved using a 25-bit absolute encoder.
