Positioning Application

A Master Drive is not required in all applications.  A Follower drive can be synchronized with an existing machine or an existing machine section provided a speed/position sensor (an Encoder) can be mounted on the existing machinery.  In these applications, Follower drive motor shaft to reference encoder shaft synchronization within one tenth of one degree is possible.

A built in local position reference is available for simple positioning applications.  The drive can also follow an external frequency reference signal from a profile generator for more complex applications.
