PPG-Drive

The drum motors in this machine use the planetary gear reduction mechanism (PPG-Drive: Precision Planetary Gear Drive), and they are more compact and cost less. With FB/FF Control (Feed-Back/Feed-Forward Control) which accurately suppress the speed variations, the rotation accuracy of PPG-Drive is almost the same level as earlier models, such as Pro C751EX/Pro C651EX.

This means that this machine is more cost effective, but almost as accurate as the earlier models.
