Innovations you

Innovations you definitely shouldn’t miss at WIN EURASIA 2017 CHOICE SMC’s new 4-axis step motor controller Drive controller in multi-axis drive system Low-maintenance drives for intralogistics PRODUCT NEWS Lower device costs, less programming time, less wiring work and lower space requirements – are the most important advantages of SMC’s new 4-axis step motor controllers JXC73 and JXC83. These make it possible to control up to 4 electrical actuators for individual or multiple axes simultaneously. Programming is done on a PC using a USB 2.0 interface. The new 4-axis step motor controllers from SMC can reach entered target positions in 2 ways: for linear interpolation, only the target position and the speed of an axis are required. From this information, the controllers calculate all of the values of the X, Y and Z axes that are necessary for three-dimensional movement. Alternatively, it is also possible to use circular movements. If you enter the coordinates of the target position, the rotation direction and the centre point, the controllers use circular interpolation to calculate all of the X and Y values required to run the circular path. Under the name of SI6, Stober presents its latest drive controller in multi-axis drive system. With a width of only 45 mm, the SI6 has compact design and requires extremely little space in the control cabinet. Even more decisive than the compactness is the omission of redundant supply units. The entire series of drive controllers is connected with a central supply module. The fuses and cabling for each individual axis are also distributed from here. The drive controllers are connected with each other via quick DC-link modules and by using double axis modules, unused power reserves of an axis can be used for other axes. In regards to acceleration, the SI6 in combination with the Stober’s synchronous servo motor, accelerates from 0 to 3 000 rpm in 10 ms. For the safety concept, Stober counts on the STO (”Safe Torque Off”) function that can be controlled via terminals as well as via Fail Safe over EtherCAT (FSoE). Nord Drivesystems now offers standardized drive units in 3 versions for typical requirements in conveying applications. The line-up of LogiDrive systems enables a quicker selection of the drive for a given application. IE4 synchronous motors with 1.1, 1.5, and 2.2 kW rated power are combined with two-stage helical bevel gears for speed ranges of 0 to 565 rpm or 0 to 482 rpm. The transmission is continuously variable in the range from 1 to 500. Distributed frequency inverters for installation on the conveyor frame near the motor ensure accessibility. They feature a key switch for disconnection from the plant control system and a direction switch for local set-up. LogiDrives are designed for horizontal or inclined conveyors. The motors feature a high overload capability. The system has all components that can be serviced separately. This significantly reduces maintenance costs. Nord integrates all standard fieldbus and Industrial Ethernet interfaces directly in the AC drive. WORLD OF INDUSTRIESMOTION, DRIVE & AUTOMATION 1/2017

Automatic torque limiter In case of rough operating conditions, the drives particularly are encapsulated and therefore hard to access. But these machines require reliable overload protection. Mayr, the specialist in power and torque transmission has now developed a robust, disengaging torque limiter which can withstand Plug and play adapters for Simatic controllers For error-free connection of modules to the Simatic S7- 1500 controller, the company Phoenix Contact now offers controller-specific front adapters as part of the Interface system cabling range. Due to its plug-and-play concept, these adapters reduce the wiring effort to just a few steps. The adapters are easily swiveled into the digital or analog I/O cards and connected to the ‘Varioface’ interface modules via pre-assembled system cables. They are available as Servo motors for highprecision applications With the new DSH1 series, where “H” stands for high precision, the drive specialist Baumüller has created another derivative in its servo motor range. The latest product impresses with a particularly low torque and thus achieves an extremely high control high loads and also automatically re-engage. In case of overload, if the torque exceeds the value set on the clutch, a patented disengagement mechanism of the EAS-reverse torque limiter, separates the input and output almost free of any residual torque with high accuracy. ‘passive’ components with various connection methods including knife disconnection. www. accuracy. The DSH1 high precision servo motors were developed specifically for applications with the high precision e.g. in the handling and robotics field, including welding robots that produce components with a precise and high-quality welding seam. Servo drive even with a sine wave filter B&R has made further developments to the current control loop for its Acopos P3 servo drives. Users can now implement a sine wave filter without having a negetive effect on the drive control performance. These developments are aimed at providng the machines the advantages of a sine wave filter while the Acopos P3 retains its usual high performance. By converting the voltage signal from a square waveform to a largely sinusoidal one, sine wave filters help improve energy efficiency, reduce strain on the motor and decrease electromagnetic noise on the motor cable. They also smooth out the current curve, which reduces both acoustic noise and motor losses. OPC UA communication With a new extension of the OPC UA specification, which Beckhoff played a prominent role in developing, the publisher/subscriber principle is being introduced into the established and standardized OPC UA communication protocol. One particular advantage is the much simplified configuration resulting from direct integration into the TwinCAT 3 environment. Communication is initiated directly from the TwinCAT 3 runtime, creating a realtime-capable communication channel via OPC UA. Conventional client/server applications are decoupled from one another in publisher/subscriber-based data communication and no longer need to “know” each other. Planetary gearboxes for better performance Neugart’s 2 latest products: a high precision gearbox with helical gearing and a right angled gearbox with compact output flange, offer solutions to the increasingly demanding challenges the customers face. Neugart’s ‘PSBN’ is an apt combination of a precision planetary gearbox and efficient bearing technology. The WPLFE, is the right angled gearbox with compact output flange, and is extremely helpful when things are tight. The WPLFE saves up to a third of the space and has up to 5 times higher torsional stiffness. Due to its standardized flange interface, it is simple to assemble.
