L7P

The LS Electric L7P servo drive is a motion control drive with an Indexer Function Type for precise speed and position control of servo motors. It supports multiple control modes and feedback options, and the Indexer Function Type enables easy programming of motion profiles through simple commands. This makes it a flexible and versatile solution for a range of industrial applications, including robotics, CNC machining, and automated assembly systems.
