DC servo controllers
20 October 2015
Sprint Electric presents its latest range of DC servo controllers at SPS IPC Drives. Units in the extended XLV range are miniature, fast response DC motor speed controllers, offered in a compact, easy to use DIN rail mounting package. They are designed for use with permanent magnet brushed DC servo motors rated from 4 to 12A.
The controllers are suitable for use on DC supplies up to 48 V and can be used in either current (torque) or speed control modes. For highly dynamic applications, a shaft-mounted DC tacho-generator is recommended for speed feedback. In less demanding applications, armature voltage feedback (Avf) can be used.
The reference signal for both current and speed control can be either bipolar (+/-10 V) or unipolar (0 to 10 V). Motor speed can be controlled in both forward and reverse directions. An adjustable current limit and fast-acting current control loop protect the controller and motor from sustained overloads. Hall 1 Stand 458
