SPS IPC Drives
At the SPS IPC Drives Congress, Elmo Motion Control (Israel) has introduced its flagship Gold Twitter product: according to the company, the smallest high-power servo drive available on the market today.
AT 18 g IN WEIGHT, and less than 13 cm3, the servo drive delivers up to 4000 W of qualitative power, currents such as 50 A / 100 V with advanced servo capabilities, and support for Ethercat and CANopen. As CANopen is employed as the default communication, the version including Ethercat weighs 22 g instead of 18 g. The servo drive is also compliant with international safety and EMC standards and STO certification.
The servo drive operates in current, velocity, and advanced position modes. It supports any feedback sensor in single, dual and gantry loop configurations. The servo drive incorporates the company’s proprietary Fasst (Fast and Soft Switching Technology) resulting in > 99 % efficiency with negligible EMI.
It is set up and tuned using the Windows based Elmo Application Studio II (EAS II) software. The servo drive can operate as a single-axis control solution or as part of a multi-axis control system in a distributed configuration real-time network. Among its features, it incorporates an internal breaking shunt resistor and a multi extended I/O interface.
"At a record-setting power density while delivering ultra high power of 4000 W, we improved the efficiency by 200 %, reduced the volume by 75 % and increased the power density by more than 400 %. The Gold Twitter is an excellent solution for applications that require very high servo performance but are very limited with space. In addition, the Gold Twitter is rugged to meet the growing needs to mount the drives "on the motor", "next to the motor", or "on the moving mechanical load", thus ensuring the high servo performance and saving huge costs in hardware and cabling. We’re not aware of anything in the industry that approaches this power and size density,” Haim Monhait, Elmo CEO concluded. The SPS IPC Drives Congress took place May 20 to 22, 2014 in Parma, Italy.
