EDB series EDB series
Features:
1. Applied with current forward-feedback control, speed observer and inertia detection functions which ,in turn, greatly improve the responsiveness performance.
2. Updated with control switch function which in turn reduce overshoot and adjustment time effectively.

EDC series EDC series
Features:

2. Updated with control switch function which in turn reduce overshoot and adjustment time effectively.

Pronet series Pronet series
Features:
1. The responsiveness performance has been improved more than three times than our EDB series, which realizes online real time inspecting of load inertia. The gain can be adjusted at any time in order to achieve the best control effect.
2. Can match 17 bits serial encoder, which in turn enhances the position precision and low speed stability & responsiveness performance.
