With its decentralized drive system "KFM Safety" provides the Siei-Areg (Sales: Gefran) An intelligent solution for safety doors on machines from different areas of application. Together with TÜV Nord certified to EN 61508 is sought. The KFM Safety combines asynchronous motor, inverter and line filter and communication, fieldbus, analog and digital interfaces, encoders and protection functions in a compact body.
That makes him a complete, general-purpose drive and positioning. Once the TÜV certification is complete, it is the degree of protection according to EN SIL2 61508 and EN 13849 get the category 3 with the Performance Level d. The following protection functions are implemented in this drive solution: safe torque off (stop) STO (Safe Torque Off), Safe Limited Speed (SLS Safely Limited Speed) and safe limited torque SLT (Safely Limited Torque)
The KFM Safety integrates easily and compactly in different applications. Its use reduces cabling costs significantly and consumes less space in the cabinet. On these may in many cases be dispensed with entirely. The machine protection solution is used, for example, security doors for machine tools, injection molding and packaging machines as well as in assembly machines, conveyors and in handling technology. Different gears and pulleys provide as part of the drive system to adapt to different customer requirements.
The 2048 pulses with high per revolution encoder resolution, a 32-bit position control and the powerful control for flexible, precise positioning and a secure holding the position. The position of "close door" must learn the door actuator first. Recognizes the drive at the "door" operating an obstruction (force> 150 N), the internal STO function is activated and the KFM safety stops immediately, then moves a few millimeters (adjustable) in the "door" and holds the positioned so that the obstacle can be removed.
The software "E @ sy Drives" is included. The menu and configuration interface with software oscilloscope for optimum setting, drive adaptation and diagnosis is based on a Windows interface. The calculated parameters can be saved to the PC and loaded into other KFM safety units.
