2. Introduction
The FS340 / FS641 units are suitable for control of “Flying Shears” and “Flying Saws”,
frequently used for cut-to-length applications with endless material, where the material is in
continuous motion and cannot be stopped during the cutting process.
The mechanical construction provides a carriage with a cutting tool, following synchronously
the material while the cut is in progress, and then returning to a home position, to wait for the
next cut.
The FS340 / FS641 units have been designed for the special requirements of flying shear
systems, under consideration of maximum efficiency and accuracy, with minimum stress for all
mechanical parts. Very short control cycles together with intelligent motion profiles provide
excellent performance under all operating conditions.
This unit is very easy to set up. All settings can be made either by keypad and display at the
unit or by PC, with use of the motrona operator software OS3.2.
All relevant operational parameters and variables are accessible by RS232/RS485 interface. For
PROFIBUS applications, our PB251 gateway is available. Therefore the user has multiple
possibilities for remote control of all batch and cutting parameters via operator terminals, PC or
PLC systems
 This manual first provides all basic instructions for operation of model FS340
 For operation of relays and thumbwheels with model FS 641 see appendix
 For PC setup our “OS32” software is available on the CD included to delivery,
or on our homepage www.motrona.com
 For communication by PLC or IPC or by a remote operator terminal, please
observe the serial protocol details described in our separate manual “Serpro”.
 PROFIBUS communication is possible with use of our gateway PB251.
