n NEW PRODUCTS Mclennan is offering a microstepping drive from the German manufacturer Phytron which is designed to be used with Siemens’Simatic ET 200SP HA distributed I/O system. The Siemens-approved TM StepDrive module is plug-and-play compatible with the Profinet- based PLC, allowing seamless addition of motion control. It has same rack-mounting design as the PLC, and is programmed from Siemens’Step7 or TIA Portal as an application program or as a Simatic Technology Object. The 24-48V DC drive has a variable peak current up to 5A, or can be used as an indexer module with pulse and direction output for interfacing with more powerful external drive stages. The drive is suitable for two-phase stepper motors with 4, 6 or 8 leads and offers selectable microstepping resolution from full-step to 1/256 steps (51,200 pulses per rev). The maximum step frequency is 250,000 steps/rev, while a separate rotary encoder and a counter in the PLC can provide position verification for higher microstepping rates. Controller modes include relative and absolute positioning, move to reference point, variable free- run speed, position setting and motor/emergency stop. The drive stage version offers 100mA adjustable increments up to its 5A peak, equating to around 200W of shaft power. The controller has three digital inputs for limit and reference switches, and digital outputs of clock, direction and run for feedback to the PLC. Functional safety, such as Safe Torque Off (STO), can be included using the distributed I/O system’s EN 61508- certified safety modules. Mclennan 01252 531444 www.mclennan.co.uk Micro-Epsilon has launched a compact confocal chromatic displacement sensor for precise measurements of distance, surface roughness and thickness. The IFS2407-0,1 sensor offers a measuring range of just 100µm (0.1mm). This, combined with a resolution of 3nm, enables reliable, precision measurements of transparent layers such as glass or plastic film/substrates with thicknesses from just 5µm. A light-intensive model is available for high-speed processes. The sensor offers a large tilt angle, made possible by the numerical aperture (NA) – the degree of the light rays bundled in the optical system. Combined with a 3µm light spot diameter, the sensor can detect the finest of structures and be used for surface roughness measurements. The standard model, with an NA of 0.8, is ideal for precision measurements of rough surfaces and thin layers. The light- intensive version (NA 0.7) is suitable for high-speed measurements with short exposure times, and for dark surfaces. Confocal chromatic measurement systems are used for µm-precise measurements of displacement and distance, and to evaluate intensities. They can be used to obtain surface topographies of objects. Unevenness and scratches influence the degree of reflectance, causing a change of the signal intensity. An exact image of the target and its fine structures is produced.
