Omron’s new Junma ultra-compact servo drive offers installers savings of up to 30% of cabinet space plus significant reductions in cabling and set-up time. It is also believed to be the first servo drive that eliminates the need for tuning or programming. With drive footprints starting at just 140mm by 35mm, Junma offers two drive types: Junma ML-II with built-in motion bus, and Junma PULSE, a traditional pulse type input drive designed to be used with position controllers. Both the ML-II and PULSE servo drives are available in four power output ratings of 100W, 200W, 400W and 750W.
The self-tuning feature relies on speed loop calculation and a mechanical resonance filter to deliver optimum performance, so no control parameters need to be adjusted to match the load characteristics of a particular machine axis.
The ML-II comes with an in-built Mechatrolink II motion control bus allowing a single cable connection between controller and servo drives, and facilitating remote servo configuration and diagnosis. Combining the Junma ML-II with Omron’s NCF positioning unit delivers a complete point-to-point positioning system, offering 16-axes of positioning with linear interpolation, as well as interrupt feeding. And when connected to a PLC, the Junma ML-II is fully transparent from any remote PC via a serial or Ethernet link.
