Ultra-compact Gold Twitter servo drive delivers high power

Weighing just 18g (less than 1 ounce) and occupying a space of less than 13cm3, the Gold Twitter delivers up to 4000W of qualitative power and ultra-high currents such as 50A/100V, and also benefits from advanced servo capabilities and support for EtherCAT and CANopen fieldbus communication standards. The Gold Twitter servo drive is suitable for a variety of application configurations, and complies with international safety, EMC standards and STO certification.

Haim Monhait, Elmo CEO, says: "At a record-setting power density while delivering ultra-high power of 4000W, we improved the efficiency by 200 per cent, reduced the volume by 75 per cent and increased the power density by more than 400 per cent.

"The Gold Twitter is an excellent option 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 are not aware of anything in the industry that approaches this power and size density."

Any servo motor, any feedback sensor

Elmo Motion Control's Gold Twitter servo drive runs optimally on any servo motor and operates in current, velocity and advanced position modes. The Gold Twitter 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 per cent efficiency with negligible EMI.

Easily set up and tuned using the Windows-based Elmo Application Studio II (EASII) software, the Gold Twitter servo drive can operate as a single-axis control system or as part of a multi-axis control system in a distributed real-time network. Among its expanded features, the Gold Twitter incorporates a powerful internal breaking shunt resistor and multi extended I/O interface.
