to be built into or near machines, saving space, costs and work. Previously a single cable was needed to link the drives to the control cabinet; now, even that can be eliminated, as well as air-conditioning in cabinets. The AMP8620 module is connected to the mains and includes filters, rectifiers, two EtherCat P outputs, and charging circuits for the built-in DC link capacitors that can be used to store regenerative energy. The Taiwanese manufacturer Delta was showing a heavy-duty drive that provides open- and closed-loop control of synchronous and asynchronous motors up to 560kW at 460V. The C2000 Plus vector control drive offers speed and position control and incorporates a PLC capable of executing up to 10,000 steps. Lafert , the Italian motor-maker now owned by Sumitomo , expanded its range of IE4/IE5 permanent magnet motors by adding a frame 56 model and extending its frame 160 motors up to 37kW. It has also re-engineered its HPI family of PMmotors with integrated drives starting from frame 71 which is now available in a single-phase version. As we have reported previously, Mitsubishi used the Hannover Fair to introduce 690V versions of its FR-A800 series of inverters in ratings up to 1.5MW. Versions of the FR-A870 drive up to 200kW have built-in brake choppers to reduce deceleration times, eliminating the need for external brakes. The 690V drives are initially available in ratings from 160–200kW, and will eventually span ratings from 37kW–1.5MW. SEW-Eurodrive unveiled a series of compact, electronically-commutated ELV (extra-low-voltage) gear-motors in ratings from 188–357W at 48V DC. The interior-rotor motors in the DCA series offer high power densities and dynamics and can be configured locally. The family includes versions with planetary and right-angle gearboxes which can be supplied with single-disk brakes that are powered and controlled via the drive electronics. The gear-motors are aimed at applications such as conveyors. Siemens has extended its Simogear geared motor portfolio to include synchronous reluctance versions with outputs from 0.55– 4kW. Efficiencies are said to be“comparable to IE4”, even under partial loads. The cool-running drives offer high dynamics due to their low moments of inertia. To commission the drive, you simply enter the motor code into the converter. External fans are not needed due to the constant torque/speed curve up to nominal speed. Weidmüller has added a multifunction stepper motor module to its u-remote family. The UR20-1SM-50W-6D12DO-P module can be used to automate stepper motor applications, simply and flexibly. It has a built- in power amplifier for controlling two-phase steppers up 50W, delivering 2A at 24V DC. The 23mm-wide module has six parameterisable digital inputs and two 0.5A digital outputs for controlling actuators. CONTROLS ABB has a new version (6.1) of its System 800xA DCS (distributed control system) which has a flexible Ethernet-based, single-channel I/O system, and a new workflow that will speed up projects and allow tasks to be done in parallel. The Select I/O system is claimed to shorten commissioning times, and allows standard, pretested cabinets to be connected directly to field devices, saving on patch panels, drawings, equipment and labour. Real- time information on power consumption is available down to individual loads. Beckhoff has extended its family of ultra- compact industrial PCs with a newmodel that adds an extra PCB level and offers a modular interface. The C6032 IPC measures 129 x 133 x 104mm and is available with processors up to Core i7 with four 3.6GHz cores. Two PCIe slots can accept modules containing pairs of Gbit Ethernet, USB 3.0 or RS-232 ports. B&R Automation is now offering its Power Panel operator panels for swing-arm mounting. The IP67-protected T50 Field HMI terminals are available in five widescreen sizes from 5–21.5”, in depths of 16.5 or 26mm. Power-over-Ethernet connections mean that one cable can carry both power and communications. The multi-touch panels support gestures such as swiping and zooming. Following Delta ’s cooperation with Codesys announced last year, it was demonstrating a Codesys-based motion control systemwhich complies with IEC 62231-3 and allows PLCs, HMIs and motion controls to be combined in a single platform that uses EtherCat to control field devices. Delta was also showing a PLC-based motion controller (the DXMC) with an optional Codesys Soft-PLC, which can synchronously control 32 axes in a standard version, or eight in a panel-mounting version. Lenze presented its next generation of cabinet controllers, the c500 series, with powerful processors for tasks with high demands in terms of computing power. One model splits this power between a control component and an encapsulatedWindows 10 IoT operating systemwhich, with the aid of the OpenSystem architecture, can execute Windows applications such as AI, 2D and 3D code detection, and vision system analyses. It can also process and compress data for the cloud, or for uses such as predictive maintenance. Phoenix Contact announced a series of expansion modules for its PLCnext Control controllers. The first provides an extra Ethernet interface with an additional MAC address, while future modules will support Interbus and Profibus, offering master functions to connect to existing devices. The modules are configured using the PLCnext Engineer software. Siemens unveiled an extremely powerful industrial PC which comes with up to two Intel Xeon processors, each containing up to 14 cores. The rack-mounting, metal-enclosed Simatic IPC1047 PC can run several demanding applications – such as visualisation and machine learning – simultaneously, and can drive several screens using up to two Nvidia Quadro P5000 graphics processors. At the less powerful end of Siemens’IPC portfolio, its new IPC527G PC comes in a compact format with a choice of mounting options. It is equipped with Intel Core i5 or Pentium processors, and supports up to 32Gb 27 www.drivesncontrols.com June 2019 HANNOVER FAIR REPORT n Synchronous reluctance: Siemens’Simogear gearedmotor Swing-armmount: B&R’sT50 Field HMI terminals Extra level: Beckhoff C6032 industrial PC For conveyors: SEW-Eurodrive’s electronically- commutated ELV motors
