Electromechanical NC joining module NCFH, servo press with hollow shaft motor and compact design


The NC joining module NCFH Type 2151B (in two sizes) with integrated piezoelectric force sensor for nominal forces of 1 ... 60 kN is excellent for use in assembly and joining processes monitored by force displacement. Ideal for applications with small installation space and high dynamic requirements.
  • Outstanding dynamics (speed up to 700 mm/s)
  • Two sizes cover the measuring range of 1 … 60 kN
  • Compact design without belt
  • Active compensation of process compression for exact positioning
  • Absolute encoder, eliminates reference point determination
  • Particularly low maintenance

The NC joining modules NCFH Type 2151B consist of a robust housing with the displacement sensor, integrated absolute encoder, piezoelectric tension/compression force sensor and charge amplifier. The compressive or tension forces that impact the sensor create a proportional electrical charge in the piezoelectric measuring element, which is converted into an analog voltage signal by the integrated charge amplifier. The drive motor is an electrically commutated hollow shaft AC servo motor which is controlled by a servo amplifier. This servo amplifier provides constant speed independent of load. Standard functions like block pressing, position pressing and force feedback controlled pressing as well as intermediate positioning are supported. The NC joining module NCFH can be operated with the IndraDrive servo amplifier in combination with maXYmos NC Type 5847. The communication between IndraDrive and maXYmos NC takes place in real-time via SERCOS III. Several field bus slave interfaces are available onboard for customer controlling. PROFIBUS, PROFINET, EtherNet/IP or even EtherCAT can be used with the maXYmos NC at the customer’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.
