MLAC7061 Full Digital AC Servo Driver
Summary
MLAC7061 is a vector-controlled all-digital AC servo driver designed and manufactured by our company with DSP. It consists of three feedback loops (position loop, speed loop and current loop). It can work in position, speed and torque mode. It is suitable for driving AC servo motors with DC voltage of 20V-70V and power of less than 400W.
The product has the following advantages:
1. High dynamic performance, high peak torque, low speed torque smoothing
2. Fully closed-loop function
3. Support linear motor drive, position resolution Kodak 0.1 um
4. Support multiple control modes, multiple input modes
