Product Description:

The KDA 3.1-150-3-APS-U1 is an AC digital servo drive developed to impart high-level functionality in precision-based systems. It has position, velocity, and torque control with a global method of controlling servo motors precisely. The drive has a maximum current rating of 225 A, making it suitable to meet heavy loads while assuring safe operation.

Its compatibility with both resolver and EnDat encoders offers versatile feedback solutions, allowing integration with different motor systems and optimized dynamic performance. The communication takes place through SERCOS in conjunction with special analog and digital inputs and outputs to be assigned, making it easy for integration in broader automation systems and control platforms. Internal cooling of air protects against overheating risk, keeping operating conditions consistent, and ensuring reliability with steady or heavy usage. The drive is heavy-duty and has a compact design, 390 mm in height, 135 mm in width, and 320 mm in depth, which is suitable for cabinet mounting where space is limited. All elements of the design support stability, flexibility, and accuracy of control, allowing the unit to be deployed in a wide range of configurations. Digital nature of the drive allows for high-level control over motor operation, which is very useful in applications where strict synchronization and timely adjustments are required. Support for multiple communication options makes the drive flexible in modern systems, allowing scaling of configuration and application. Built to perform with reliability and efficiency, the KDA 3.1-150-3-APS-U1 provides a combination of power handling and space-saving design.

Thus, it is a suitable choice for industrial applications requiring consistent servo motor performance with advanced digital control. By providing strong current capability, adaptable feedback, and intelligent communication interfaces, it delivers efficient performance through demanding applications while providing stable operation in controlled environments.
