36 n SPS REPORT February 2020 www.drivesncontrols.com than other couplers. The bidirectional IO- Link capability can be used to control actuators and valve terminals at the same time as collecting data. In combination with a suitable IO-Link master, almost any fieldbus system can be supported. Contrinex has a range of light curtains with a Bluetooth-LE interface that allows remote wireless configuration, and real- time communications of status or diagnostic data to a smartphone or tablet. The YBES curtains do not need safety relays, cutting installation costs. They comply with PL e and SIL 3. Motortronics , the US motor control specialist that in 2018 acquired the UK soft- start pioneer Fairford , used SPS to launch its new European operation which is offering low- and medium-voltage soft- starts for motors from 1.1kW–15MW. According to the company, the portfolio constitutes “the world’s most innovative and largest range of soft starters”. Phoenix Contact was showcasing a configurable safety system for applications up to SIL 3 / PL e, with up to 160 safe I/Os. The PSRmodular system uses 22.5mm-wide modules which can be arranged next to each other without configuration on DIN rails. Modules are available to monitor safe motion, e-stops, door locks, light grids and pressure mats. Safety functions can be implemented in accordance with EN 61800- 5-2. There is a safe analogue module for monitoring 0/4–20mA or 0–10V signals. Phoenix also has new power supplies with 40A outputs which it claims are the most powerful available. A single-phase version of the Quint supplies has multi- stage PFC (power factor correction) on the input to optimise efficiency across the power range. Three-phase versions do not generate inrush currents, preventing tripping of backup fuses after short mains breaks. Rittal was demonstrating a mobile modular wiring table for panel-builders and switchgear manufacturers. The Wire Station 540 is based on an adjustable-height worktable is used to assemble wiring automatically or manually. It is designed to be used in conjunction with Rittal’s automated wire terminal processing machine and ePlan’s Smart Wiring software. Schmersal launched a slim electromechanical solenoid interlock which can be combined with three different actuators: a straight actuator for sliding doors; an angled actuator for large revolving doors; and a movable actuator for smaller revolving doors. The AZM 150 can deliver an interlocking force of 1.4kN. Sigmatek is offering a pair of 25mm- wide DIN-rail power modules that can deliver 10A continuous (20A peak) and can be used to control synchronous servomotors. There are two models: the S- Dias DC-101 with a 12-bit resolver input for position detection; and the DC 102 which works with a 32-bit incremental encoder input. 24V DC outputs can control holding brakes. Wago was showing a range of power supplies in ratings from 120–960W, which can connect to both PLCs and IoT gateways via snap-on comms modules. Data from the Wago Pro 2 supplies can be analysed to optimise energy use, and a central PLC can switch them on or off remotely via hardware signals or bus commands. Efficiencies are up to 96.3%. WEG has added a new frame size to its SSW900 series of soft-starts, covering the range 480–670A. The starters incorporate PLCs, programmable algorithms for induction motors, protection functions, and flexible torque control. They support star or delta motor connections, as well as string connections, allowing the three motor phases to be wired directly to the thyristor pairs. This means that the soft-start only has to provide 58% of the rated motor current, allowing a smaller device to be used. WEG has also extended its CWB series of contactors with frame sizes 95, 110 and 125, covering rated operating powers from 45– 55kW, 400V, and rated operating currents from 95–125A. There are also new variants: the CWBS contactors for safety applications with rated operating powers from 18.5– Configurable: Phoenix Contact’s PSRmodular safety system Mobile: Rittal’s Wire Station 540 wiring table Decentralised IP66 drive is ‘first to support IO-Link’ AT SPS, Lenze unveiled a decentralised variant of its i500 frequency inverter which, it claims, is the first to support IO-Link. The IP66-protected i550 protec drive will initially be available in ratings up to 2.2kW. The range will be expanded later up to 75kW. Incorporating IO-Link in the drives will make it easy to integrate sensors and actuators with the master control level to exchange process, asset or parameterisation data, without needing special cables or to address the nodes manually. If an IO- Link master is already in use on a network, the new drive can be connected at a low cost – regardless of the higher-level control system. Devices are parameterised automatically during set-up or when they are replaced during servicing. Lenze claims it is the first drive manufacturer to support IO-Link v1.1 in its products, which is necessary for this automatic exchange of data. The IO-Link port can also be connected using the new ASi-5 decentralised communication standard. Other common fieldbus interfaces will be available as options. Lenze says the new drive is particularly small. For example, a 0.75kW version occupies 3,100cm 3 – claimed to be half the size or less than its rivals. The IP66 or Nema 4X protection resists high temperatures, dust, dirt or water jets during cleaning. The new drive is particularly suitable for large machines, distributed material flow applications, or where cabinet space is costly. There is no need for expensive shielded motor cables, and several inverters can be connected to one power bus to reduce costs.
