New servomotors with artificial intelligence

23.03.2022/XNUMX/XNUMX | The artificial intelligence in the maintenance of drives is based on large data sets from production. Patterns are recognized that can be used to make precise predictions about the condition of the systems. "In addition to preventive and corrective maintenance, predictive maintenance is the mainstay of maintenance," explains Daniel Sperlich, Product Manager – Servo Systems at Mitsubishi Electric.

Thanks to AI, companies can have a targeted maintenance decide for their servo drives and carry them out at the right time. "The artificial intelligence recognizes if the maintenance has to be carried out earlier than planned," says the product manager. Real-time data, well-founded forecast models and plant trends make 'on point maintenance' possible – before failures occur and only when necessary.

AI supported maintenance of servo motors

Ever since the development of his first digital servo amplifier in 1987, Mitsubishi Electric collects operational data about its servos and their peripherals. The engineers have now incorporated this many years of experience into the development and construction of the Melservo MR-J5 series.

The new Servomotor Portfolio uses the company's own Deep learning AI Maisart (Mitsubishi Electric's AI creates the State-of-the-ART in Technology) to plan optimal maintenance work. Integrated Sensors in the devices provide an overview of the status of internal components in real time. In addition, mechanical components associated with the drives such as ball screws, belts and Transmission supervised.

Correctly select and monitor servo safety brake

These capabilities are complemented by network technology CC-Link IE TSN with Gigabit bandwidth and Time-Sensitive Networking (TSN) functionalities. This allows large amounts of data for time-critical control tasks and less volatile AI analysis to be transmitted without delay.

Powerful servo technology up to 6700 min^-1

With a Mel servo MR-J5 servo motor The system also allows the productivity of a drive to be maximized. the extremely powerfule Electric motor reaches a speed of 6700 rpm with minimal size^-1 Nominal speed. The MR-J5 servo motor is 30% shorter than a comparable electric motor. All customers like the one-touch functionality. Up to three axes can be positioned with one amplifier.

The series also includes compact servo amplifiers with a speed/frequency response of 3,5 kHz and communication cycles of 31,25 μs. One feedback unit in the servo amplifier also saves energy.

Dynamic servo motor with CC-Link IE TSN technology

22.03.2021/XNUMX/XNUMX | The new TSN compatible Servo motor series Mel servo MR-J5 from Mitsubishi Electric offers dynamics, precision and multi-axis synchronization. This makes the servomotors particularly suitable for applications in the food and beverages industry as well as for life science and the printing and paper industry.

The servo drives have a number of safety functions as standard and functions for Predictive Maintenance (predictive maintenance). This enables users to increase the availability and productivity of their machines. The servomotor response is 3,5 kHz and the minimum cycle time is 31,25 µs. With the associated Melservo-J5 motion module up to 256 axes synchronize.

DC motor and other drives for medical technology

The OPERATION such servo motors is simple. The new quick-tuning function automatically generates all parameters within approx. 0,3 s. The machines are then immediately after the release of the Engines ready for use. This ensures smooth operation with significantly reduced time and effort required for commissioning.

Communication of the servomotors

An important prerequisite for the improved performance of multi-axis servomotors is the integration of the CC-Link IE TSN technology (Time Sensitive Network) with 1 Gbit / s transmission speed. It ensures the synchronization of all connected devices, including Security devices, which can be connected to the same network like classic controllers.

The devices thus offer integrated, continuous Security concepts in the control, I / O and drive level. All safety functions such as STO / SS1 / SS2 / SOS / SBC / SLS / SSM / SDI / SLI / SLT are configured in the software. The devices are IEC / EN61800-5-2 compliant for a simplified safety certification. Other network protocols such as Ethercat (CANopen over Ethercat, CiA 402) are also offered as standard.

Potential savings in servo drives

Also functions for predictive maintenance are integrated into the motors. In this way, system availability can be increased and unplanned machine downtime reduced. This saves time and costs. These functions of the engine are supported by Mitsubishi Electric's Maisart AI technology. It enables this new servo drive to detect wear on the mechanical machine components long before the engine needs scheduled maintenance.

Machine safety online is available at the Schmersal Smart Fair

The servo drive offers even more potential for savings. The Machinewiring was through a single Cables for encoder, power and electromagnetic brake simplified with a new one-touch lock connector. This one makes the tightening of screws superfluous. The 26-bit absolute encoder with 67 million pulses per revolution ensures precise motion control in demanding applications. The elimination of an internal battery, on the other hand, reduces the maintenance costs for the motors.

Servo amplifiers with open network connections for global use

02.05.2018/XNUMX/XNUMX | the Servo Open Network Functionality in the "Melservo MR-J4" amplifier series makes it possible to serve the changing international performance requirements of modern high-end machines in the area of motion/control with just one solution. Thanks to the multi-network interface, the compact drive solution from Mitsubishi Electric has interfaces to all relevant motion systems worldwide, which makes it easier for machine builders to access the global market.

With its open network connection, the amplifier series Mel servo MR-J4 a globally usable and powerful drive solution that can be easily set up for CC-Link IE Field, Profinet, Ethercat and Ethernet/IP. By allowing machine builders to freely choose their preferred protocol, they are able to supply customers worldwide. No matter whether in Profinet-dominated parts of Europe or in Asia, where CC-Link IE is predominantly used.

“Because we are one of the global players in the field of automation technology, we have service partners and branches all over the world. In this way, we can offer our customers on-site service for their systems and guarantee manufacturer support for commissioning and maintenance,” argues Amir Dehnavi, Product Manager Servo Motion at Mitsubishi Electric.

User-friendly machine cycle times

There is one for each of the networks Quick Start Guide and example projects or function blocks for uncomplicated commissioning. These can be used directly or expanded. The servo amplifiers have proven to be particularly user-friendly and easy to set up. A graphical software tool launches functions such as advanced vibration suppression or real-time autotuning (one-touch tuning). This automatically records the optimum parameter values for machine operation and suggests them to the user. This makes the system particularly user-friendly and can reduce machine cycle times.

The Power range is 0,05 to 22 kW and is supported by a large selection of different engines. They are extremely compact and require half the space of comparable products. In addition, the motors of the series offer a significantly above-average power density.

All servo drives of the MR-J4 series are equipped with an electronic and mechanical condition monitoring fitted. The servo controller draws attention to the need for maintenance in the form of a warning if electronic components are approaching the end of their service life or if the torque increases abnormally. In this way, maintenance measures can be optimally planned and costly failures prevented.
