34 n SPS REPORT February 2020 www.drivesncontrols.com Weidmülle r has a new IO-Link configurator for its u-control 2000 controller which allows IO-Link devices to be configured and parameterised independently of the network and controller used. As well as an IP20 master module with four individually configurable IO-Link ports, there are two IP67 modules that can be installed close to machines. Yaskawa is extending its controls range with new versions of its Slio EtherCat CPU 015N and Slio Profinet CPU 015 and 017 that support OPC UA. There is also a free firmware update (v3.0) that adds OPC UA server functions to its Micro M13 and Slio 013 Profinet CPUs. The Profinet CPU family will be joined by the Slio 019 with 3Mb of memory and a built-in Profibus master. ELECTRICAL AND SAFETY ABB has upgraded its Slimline XR LV switch- fuse disconnectors and claims to have cut their power losses by up to 35%, from 357W to 230W, thus reducing heat losses and allowing space savings. The disconnectors can link to ABB’s Ability cloud platform. If fuses blow or temperatures or currents exceed set limits, alerts can be issued. Balluff has developed an inductive coupling system which can transmit 1.7A (40W) as well as IO-Link signals continuously across an air gap. The power capacity is said to be three times higher Safety delay modules will boost machine availability The German drives-maker Baumüller has launched a series of safety modules for its b maXX 5000 inverters with freely parameterisable delay times. The delay is switched between a safety function and the associated STO (Safe Torque Off) reaction, protecting machines against damage in the event of a fault, and minimising downtime. The SAF 002/003 safety modules offer a choice of safety functions. For example, if a limit value is exceeded during the safe monitoring of speed, the system can trigger the STO function, which switches the drive to a torque-free condition. However, the motor may not come to a controlled standstill, which means it may coast down. The delay time can be set by the user, depending on the safety function. For instance if, during SLS (Safe Limited Speed) monitoring, the set speed is exceeded, the delay time is started and the module simultaneously sends a signal to the drive to perform an action which can be parameterised in advance. For example, the drive can be decelerated in a controlled manner within the set time. Only when the machine has come to a standstill, is the drive switched safely to a torque-free condition. A typical area of application for this function is the textile industry, where it could prevent needles breaking or errors occurring in embroidery patterns, and allow production to resume swiftly. If a machine operator enters a machine’s danger zone, safe monitoring will start and the speed will be reduced automatically. If the SLS monitoring detects that the set speed limit has been exceeded, the safety module will switch the previously set delay time on automatically, before triggering the STO function. The controller receives a signal to remove any needles from the fabric within this time before STO is executed and the drive is switched torque-free.
