Four control modes

Quick dynamic response

Cycle-By-Cycle current limit

KD700 drives are equipped with four kinds of control modes, V/Hz, SVC1, SVC2, VC, fulfilling a wide variety of demanding industrial applications.

Torque response time of KD600 drives is as short as 10ms at SVC1 or SVC2 mode.

The KD700 drives are equipped with the function of cycle-by-cycle current limit. The drive knows how to adjust its output frequency and current suitably to avoid trip when there is a saltation at the load.
