Wieland presented a 45mm-wide safety controller with six basic functions for safe speed, position and direction monitoring. The samos Motion Pro controller incorporates 25 speed-monitoring functions, and can monitor up to 100 speed or position ranges. Ethernet is built in, avoiding the need for a separate gateway. Motion sensors detect pulses up to 70kHz, which the controller converts into speed, angle, position and direction. MECHANICAL AND LINEAR Bonfiglioli announced four new ranges of precision planetary gearboxes as part of its Effective line: the compact TQFE series covering 18–155Nm; a right-angle version called TQFEK; the MPE series with a torque range of 5–155NM; and a right-angle version called MPEK. Bosch Rexroth has extended its ready- to-install MKK (ballscrew) and MKR (toothed belt drive) linear modules upwards with a new 140 size. The modules can be supplied with integrated, non-contact measuring systems and can be connected to central lubrication systems. The belt-drive versions come in lengths up to 9.8m and the ballscrew versions up to 5.4m. B&R Automation has produced a IP69K- rated washdown version of its AcoposTrak “intelligent” track system which can be pressure-washed at temperatures up to 80°C. The stainless-steel track system is also protected against dust and can be used in both dry and wet areas. The track’s chemical-resistant surfaces prevent particles or fluids from penetrating the interior of the shuttles or segments. The German brake specialist Intorq claims to be setting new standards for servo brakes with its “revolutionary” BFK518 spring-applied brake which, it says, combines the advantages of spring and permanent-magnet brakes. The compact device is designed to offer holding and emergency-stop functions for servomotors. High braking torques are achieved by using a large friction radius rotor with a small air gap. No setting or axial positioning are required. The Danish integrated motor specialist JVL announced an integrated linear stepper motor that can deliver a force of 90–900Nm using leadscrew or ballscrew drives. The MIL171/176 motor incorporates control and drive electronics, an absolute multi-turn encoder, and M12 connectors, and supports 12 different industrial Ethernet protocols. Eight I/O points can be configured as digital I/O or analogue inputs. JVL has also come up with a compact electromagnetic spring brake designed to be mounted on stepper and servo motors with Nema 17 42x42mm flanges. The MAB17 brake will hold the shaft fixed at power-off. When 24V is applied, the brake is deactivated and the motor can turn. The brake has a holding torque of 0.5Nm but higher-torque versions can be ordered. At SPS, JVL also announced a range of hollow rotary actuators for use with its MAC and ServoStep motors, as well as motors from other manufacturers. The HLMT actuators come in five sizes with flanges from 42–130mm and torque ratings from 5– 142Nm. Maxon motor was previewing a range of zero-backlash, hollow-shaft cycloidal gearboxes prior to their launch planned for April. The high-power-density Cyclo-Flex- Wave gears will come in three diameters (50, 60 and 70mm) and have continuous torque ratings from 4.8–34Nm.
