The Gold Bee series from Elmo Motion Control are high intelligence density servo drives for extreme environments. Available with full support from Heason Technology, Elmo Motion’s UK distribution partner, the ultra-small PCB mount package, measuring just 35x30x14.4mm, can deliver up to 4,000W of power with current ratings to 50A at 100VDC. The drive has a range of features including a choice of EtherCAT or CANopen networking, Safe Torque Off and multiple feedback options.
As part of Elmo Motion’s ExtrIQ, Gold servo drive range, the diminutive Gold Bee is built for extreme environment conditions with wide current control and a current loop dynamic range of 2000:1 for high bandwidth servo performance. It can be used with brushed and brushless servo motors and is configured for a predetermined DC voltage and current range. Nominal supply voltage through the range is 85 or 170VDC with continuous current to 30A and peak current at 2x continuous ratings for standard versions. Elmo Motion also offers ‘no peak current’ versions where continuous current is up to 50A. Such current control is made possible with Elmo’s thermal management drive design that realises safe and reliable high power density and cutting edge performance. The Gold Bee is specifically built for extreme environments with temperature ratings of -40°C to 70°C and vibration up to 14Grms.
The drive features dual feedback inputs with provision for absolute serial encoders, incremental encoders, digital and analogue halls as well as resolvers - making the choice of feedback very flexible to suit a wide range of servo motor technologies. Servo loop sampling times are as fast as 50μs for current, velocity and position.
Whilst stand alone use is perfectly possible, Gold drives such as the Bee particularly suit real time deterministic multi-axis motion control when paired with Elmo Motion’s EtherCAT Gold Maestro motion controller. With delta robot and kinematics support, motion blending and superimposed motion, polynomial motion segments, PVT and spline support, the Gold Maestro enables full motion and machine control with support for high level, multi-axis programming environments such as IEC 61131-3, Microsoft .NET, Win32 and Native C/C++ programming. Even the Maestro’s
CANopen version offers synchronised motion that is significantly improved. Heason Technology can supply the Elmo Motion Gold Bee servo drive as separate components with compatible servo motors and motion controls - or integrated in customised motion systems as part of its in-house design and build service.
