Miniature servo drive can be mounted on the motor

30 June 2017

Elmo Motion Control, a leading provider of advanced and cost-effective motion controls, has announced the Gold Twitter servo drive, claimed to be the smallest, high-power option available.

At just 18g in weight, and less than 13cm3, the Gold Twitter delivers up to 4000W of qualitative power, ultra-high current such as 50A/100V. There is support for EtherCAT and CANopen fieldbus communication standards, compliant with international safety, EMC standards and STO certification. CEO Haim Monhait says Elmo has improved the efficiency by 200%, reduced the volume by 75% and increased the power density by more than 400%.

"The GOLD Twitter is excellent for applications that require very high servo performance but are very limited with space," Monhair says. "In addition, it is rugged enough to meet the growing need to mount drives on the motor, next to the motor, or on the moving mechanical load."

The Gold Twitter will run on any servo motor and can operate in current, velocity, and advanced position modes. It supports any feedback sensor in single, dual and gantry loop configurations.

Based on the premise that 'the best way to dissipate heat is not to generate it in the first place' the Gold Twitter incorporates Elmo’s proprietary FASST (Fast and Soft Switching Technology), resulting in >99% efficiency with negligible EMI.

Easily set up and tuned using the Windows-based Elmo Application Studio II (EASII) software, Gold Twitter 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 expanded features, the Gold Twitter incorporates a powerful internal breaking shunt resistor and multi extended I/O interface.
