Delta, a global leader in power management and smart green solutions, has announced the official release of the new ASDA-A3-EP servo drive to the market. The latest addition to its ASDA-A3 series of high-end AC Servo Systems, the EP model is designed for high-performance applications that require advanced operational safety. Compliant with standards including IEC 61508 (SIL 3) and ISO 13849 (PL e), it features a built-in Safe Torque Off (STO) functionality, as well as an optional extended safety card that offers thirteen advanced safety functions, including SS1, SS2 and SOS.
Commenting on the introduction of the ASDA-A3-EP servo drive, Stephen Hu, Head of Product Management Team EMEA, said: “The servo drive and motor are the primary interface between automation and machinery, which means that safety must be our top priority. Delta’s commitment to it is reflected in the drive’s compliance with the latest safety standards, the STO functionality, and the inclusion of safety functions including SS1, SS2, and SOS. The ASDA-A3-EP is equipped to successfully navigate even the most demanding market major challenges, while remaining safe, simple to integrate and to use.”
Developed for the needs of machine builders, the ASDA-A3-EP servo drive is also well-suited to system integrators and application providers. Its user-oriented design delivers benefits ranging from simplified integration to flexibility and competitive costs, thanks to the rapid device setup and installation time, which enables it to swiftly deliver measurable value to users. The safety card function adds a new dimension to the solution, ensuring that it can meet the requirements for future machinery development and integration with maximum safety for human operators. They also benefit from safety features that drastically shorten the reaction times between the motion end effector and human action.
Engineered with market feedback
The ASDA-A3-EP servo drive’s design specification and functionality is the result of deep cooperation with high-end machine builders. Their experience and feedback informed the development of the ASDA-A3-EP platform, which enables it to meet the needs of premium machine builders across central Europe, North America, and Asia.

Flexible options with fast and reliable communication
The ASDA-A3-EP features EtherCAT interface - with extended sub-protocols FoE, EoE and FSoE - and the drive is also equipped with a TCP/IP port and support for IoT nodes. Leveraging EtherCAT's high-speed communication, the ASDA-A3-EP transmits Ethernet data and files directly to enable faster communication. The FSoE allows high reliability with robust error detection and validation mechanisms. For added flexibility, the servo drive can integrate third-party motors if necessary, while the safety function can be activated easily using a simple digital wired signal.
User benefits and optimized TCO
The ASDA-A3-EP has been developed to be easy to set up, while users also benefit from the considerable attention paid to human interaction with the motion application. Its total cost of ownership is reduced thanks to advanced connectors in the drive, which can be further reduced when combining with Delta’s battery-free motor. The streamlined wiring also reduces machine downtime and helps maintain production rates.
