- Page 9 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.

Page 12: Power Supply
Power Supply The FS340 synchronizer accepts both, a 17 – 40 volts DC power or a 24 volts AC power for supply via terminals 17 and 1. The current consumption depends on the level of the input voltage and some internal conditions; therefore, it can vary in a range from 100 – 200 mA (auxiliary currents taken from the unit for encoder supply not included). -

Page 14: Principle Of Operation
The FS340 or FS641 controller continuously measures the line speed and calculates an anticipation value to start the carriage before the cutting length is reached. Thus, the shear will exactly match the cutting position of the material upon completion of the acceleration ramp and no overshoot or oscillation will take place prior to the cut. -
Page 15: System Configuration
It is necessary to adjust the carriage drive to its maximum dynamic response (no internal ramps, no integral control loop, high proportional gain), because the FS340 and FS641 will generate the ramps which the drive has to follow with no additional delay... -

Page 22: Descripotion Of The Parameters
Descripotion of the Parameters Prior to register setting you must decide which dimensions or length units (LU) you like to use for preset of the cutting length. This could be 0.1mm or 1mm or 0.001 inch or any other resolution you desire. All further settings refer to the Length Units you decided to use. E.g. when you chose to set the length with a 0.1 mm resolution, 1000 LUs will represent a length of 100.0 millimeters with all further entries. - Page 23 Range Default F02.006 Integration Time: 0 … 9999 Time constant for the phase integrator, which avoids 0000 = positional errors.

Under regular conditions the carriage will be in the correct cutting position immediately after completion of the acceleration ramp, and the Sync Time register can be set to its minimum value of 1 ms.

Page 40: Download Of The Adjust Program
10.000 After entry of all parameters click to “Transmit Change” or “Transmit All” followed by “Store EEPROM” to store all parameters to the FS340 or FS641 controller. • At this time, both drives (line and carriage) must be adjusted to proper and stable operation over the full speed range. -
Page 41: Use Of The Adjust Program
Use of the Adjust Program The settings of the direction of rotation and the controller gain is carried out by means of the adjust program which can be opened in the menu “Tools” with “OS10 Adjust Tools” and started with the button “Start”. For reasons of safety the slave drive should be disabled at that time. While the adjust menu is running the software limit switches are disabled! The carriage drive ramps up to line speed (ramp time selectable by parameter “Jog Ramp”) and runs synchronous to the material line. -
Page 42: Set Directions Of Rotation
Set Directions of Rotation The direction of rotation must be defined for both, master and slave encoder. Make sure the Reset is switched on when you do this (the softkey must show “Reset is ON”) • Move the Master encoder into forward direction (manually or by means of a remote speed signal to the Master drive). -
Page 43: Set Directions Of Rotation Without Pc
Set Directions of Rotation without PC If there is no PC or Laptop available, the direction of rotation of the master and slave encoder can be adjusted alternatively by observing the differential counter. First of all the position error (differential counter) must be shown on the display of the device (see chapter 7.3);... -
Page 44: Setting Of The Proportional Gain
Setting of the Proportional Gain The register “Gain Correction” determines how strong the controller responds to position and speed errors of the drive. In principle, this setting therefore should be as high as possible. However, depending on dynamics and inertia of the whole system, too high gain values will produce stability problems. - Page 45 • If during forward acceleration the position error takes high positive values and the bar graph moves to the extreme right position, this indicates that the carriage drive cannot follow the acceleration ramp and you should decrease the “Acceleration 1” setting. The same is valid for “Acceleration 2”, when during reverse acceleration you observe high negative errors and the bar graph moves to the extreme left.
