Kistler reserves the right to make technical changes. Liability for consequential damage resulting ©2011 ... 2020, Kistler Group, Eulachstrasse 22, 8408 Winterthur, Switzerland The NC joining module NCFT Type 2157B... with integrated piezoelectric force sensor for two predefined measuring ranges of 0,05 ... 1,5 kN is excellent for use in assembly and joining processes monitored by force displacement. Besides a straight version with 100 mm stroke, a compact angular version with 250 mm stroke is available.• High-precision force measurement via telemetry • Certified for ISO 14644-1 class 8 clean room use (7 possible)• Extremely wide measuring range of 0,05 … 1,5 kN • High velocity for very short cycle times • High overload capacity of sensorDescriptionThe NC joining modules NCFT Type 2157B... consist of a ro-bust housing with an integral piezoelectric tension/compres-sion force sensor. An absolute encoder for precise positioning is integrated in the drive motor.The compressive or tension forces affecting the sensor create a proportional electrical charge in the piezoelectric measuring element, which is converted into an analog voltage signal by an integrated charge amplifier. The force sensor is installed directly in the tool connector for maximum precision of the force measurement. Signals are transmitted by telemetry. This means that no additional connection cables are required. The motor of the NC joining module is an electronically com-mutated AC servo type controlled by a servo electronics to ensure constant rotational and therefore translational speed. Standard functions like block pressing, position pressing and force feedback controlled pressing, as well as intermediate po-sitioning, are supported.The NC joining module NCFT can be operated with the IndraDrive servo amplifier in combination with maXYmos NC Type 5847... . The communication between I ndraDrive and maXYmos NC takes place in real-time via SERCOS III. Several field bus slave interfaces are available onboard for custom-er controlling. PROFI BUS, PROFI NET, EtherNet/I P or even EtherCAT can be used with the maXYmos NC at the custom-er's choosing. Quality data can be transmitted via the Ethernet interface through different protocols and a visualization via VNC ® or a data backup can be performed.Type 2157B...ApplicationThe NC joining module NCFT Type 2157B... is well qualified for use as a linear actuator for assembly and joining tasks in automatic production systems and manual work places. Due to clean room qualification, the NC joining module is ideally qualified for production and product testing in medical tech-nology. Another application area is precision manufacturing, such as the watch and small motor industry, and spring testing.The installation is possible vertically as well as horizontally. Fix-ation of the NC joining module at a machine frame is provided through wall mounting. A tool receptacle is available at theplunger (fig. 2 and 4, detail A).Page 2/62157B _000-948e -12.20This information corresponds to the current state of knowledge.
