SVD100 Series AC Servo Drives-Nietz Electric Co.,Ltd

Features

SVD100 series is a high performance and precision servo system. Large powers range is available with low and medium inertia servo motors; Support incremental, absolute encoders 17, 20,23-bit which offer excellent speed stability and positioning accuracy.

Bandwidth is 1.25 kHz, allowing a settling time of less than 1ms.

Servo gain self-adjustment is complete just by turning on the one-touch tuning function.

The SVD100 EtherCAT communication interface, complies with IEC61158 and IEC61800-7 for faster, real-time, accurate performance in high-end applications...
