AC servo-drive RM3

brushlessmulti-axisEtherCAT

This multi-axis servo amplifier can smoothly operate 20 to 37 kW large-capacity servo motors, and is suitable for applications such as machine tools and injection molding machines. It also has functions for estimating equipment faults from amplifier and motor operating history. 1. Smallest Size in the Industry(1) Variations of the control, power supply, and amplifier units are available for selection to build multi-axis servo amplifiers that best suit user requirements. With the smallest size in the industry, this amplifier provides a high degree of freedom, contributing to downsizing of user equipment. 2. Smooth Motion Compared with our current model,(2) speed frequency response has been doubled(3) and EtherCAT communication cycle has been shortened to half(4) to achieve smoother motor motion. This contributes to shortening the cycle time of user's equipment and increasing productivity. 3. Preventive Maintenance This servo amplifier features a function to monitor motor holding brake wear and notify users of replacement timing. It also has a power consumption monitoring function for regenerative resistors and a communication quality monitoring function. These contribute to preventive maintenance and remote failure diagnosis of user equipment. (1) Based on our own research as of October 28, 2020. (2) Comparison with our current model RM2C4H4. (3) Speed frequency response 2,200 Hz (1,200 Hz for the current model) (4) Minimum communication cycle 62.5 μs (125 μs for the current model)
