Available for for positioning systems based on ultrasonic ceramic direct-drive motors (PIline®), motion controllers offer flexibility and responsiveness. Products include single-axis C-877.1U11, which is also available in 2-axis version. Digital servo circuit maximizes dynamic performance with settling times as low as few 10 msec without sacrificing resolution or smooth operation. Multi-phase controller C-867.262 allows smooth motion with velocities as small as 1 µm/sec and below.
