Closed-loop capabilities

Now offered in five different frame sizes, the AC30 drive is reported to provide users with exceptional levels of control, from simple open-loop pumps and fans through to closed-loop process line applications.

AC30 variable speed drives give comprehensive and cost effective control of either AC induction or permanent magnet (PMAC) servo motors. Importantly, the extended range features the introduction of an optional pulse encoder feedback module, which allows users to run the drive in closed-loop control rather than open-loop. This provides optimisation in highly dynamic applications, such as winding and cranes, where the speed or torque of the motor requires accurate control.
