Compatibility Hint
Versions FS15014A and higher use some different control inputs and control
outputs and therefore are not fully hardware compatible to former versions!
You must modify a few connections at the PI/PO connector when replacing older version
against FS15014A or a higher version! See section 5.
The software has been upgraded and now includes
Batch counters for total quantity, waste quantity, total length
Registers for actual line speed, carriage speed, synchronizing error etc.
3 software limit switches to protect against carriage overshoot. No more proximity for
extreme carriage positions necessary.
Real acceleration settings instead of ramp times
Virtual master axis with adjustable simulation speed
Impulse output with scaling facility for material line
Correction register for easy compensation of slip of the measuring wheel
Enhanced setup tools in the OS30 operator software, including scope functions,
providing still easier commissioning procedures.
Improved S- shape profile for still higher cutting efficiency.

FS15016C_e.doc / Nov-15 Page 5 / 59
1. Introduction
Flying shears are used for cutting applications, where endless material to be cut to length
cannot be stopped during the cutting process and the cut must be effected “on the fly“. The
mechanical construction provides a saw or shear system mounted on a carriage, that follows
the material with synchronous speed while cutting is in progress, and then returns to a home
position to wait for the next cut. See schematics on title page.
The FS flying shear control is based on a BY150 synchronizer system. The software has been
designed for the special requirements of flying shears under consideration of maximum
efficiency and accuracy at minimum stress for all mechanical parts.
Only a few registers must be set in order to adapt the controller to the mechanical and
electrical specifications of the shear system.
A small keypad with LCD provides easy setup, but also a disc with operator software OS3.2 is
included for easy PC setup of the controller.
All essential registers like cutting length, tool width etc. are also accessible by parallel
interface, providing easy setting by remote BCD thumbwheel switch or PLC parallel output.
The unit uses a closed 19“ steel cassette for maximum EMC protection. With option SM150,
the housing can also be mounted on DIN rails.

FS15016C_e.doc / Nov-15 Page 6 / 59
2. Principle of Operation
The shear (or saw blade) is fixed on a carriage that can move forward and reverse under control
of a +/- 10V speed reference voltage of the carriage drive. Normally, a 4 quadrant DC or servo
drive is used. For lower requirements in performance, the FS150 unit can also control
1-quadrant AC drives using a positive speed reference signal and two outputs for
forward/reverse select.
The FS150 controller counts the length from the line encoder (feed roll or measuring wheel)
while the carriage is held in its rear home position.
Once the cutting position approaches, the carriage accelerates and synchronizes with the line.
A "Ready to cut" signal is generated in order to start the cutting process, while the shear moves
fully synchronous with the cutting position on the material. When the cut is completed, the
FS150 must receive a "cut complete" signal. This will cause a deceleration and a reversal of the
carriage until it has reached its home position again. All speed transitions occur with a smooth
sin² speed profile for absolutely careful treatment of screws and other mechanicals parts.

VL Line speed

Fig 1
The FS150 control 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 over swing or
oscillation will take place prior to the cut. This saves time and increases the cutting efficiency
of the shear system considerably.

FS15016C_e.doc / Nov-15 Page 7 / 59
3. Hardware Configuration
As a master drive, mostly the motor of a feed roll is used. The "master" can also be a measuring
wheel equipped with an incremental encoder.
The encoder resolution should be at least 5 times higher than the maximum acceptable cutting
error.
Quadrature encoders (TTL-types A, /A, B, /B) must be used. Where you find you must use
HTL encoders (10 –30 V, A and B output), please apply our level converter type PU210 to
generate the proper RS422 signals required.
Digital feed forward technology needs a certain minimum frequency: At maximum line speed,
the master encoder frequency should be at least a few hundred Hertz. It is best to choose the
ppr numbers of line and carriage encoders in a way to produce frequencies in the same range.
It is necessary to adjust the slave to its maximum dynamic response (no internal ramps, no
integral control loop, high proportional gain etc.) because the FS150 will generate ramps to
which the drive must follow with no additional delay.
A signal must be available to indicate completion of a cut to the FS150 controller. All control
signals must be PNP (switching to positive) with a level of 18....30 volts DC. Fig. 2 shows the
block diagram of the unit.

For reasons of proper screening, it is a must to follow the subsequent
instructions.
Where you don’t exactly observe these grounding and screening rules, it is
almost for sure that you will have problems later!
a. The minus wire of the power supply must be connected to the grounding screw on the front
plate of the FS150 controller with a short wire of at least 0.75 mm².
On site of the power supply, the minus output must be earthed.
Where the wires between power unit and FS150 controllers are longer than e.g. 1 meter, it
is advisable to ground the front plate of the controller again by a separate wire, on the
shortest way possible.

b. All screens on the controller side must be connected to the housing of the corresponding
Sub-D-connector. This is valid for encoder cables, analogue output and PI or PO lines.
Where you use Sub-D-connectors with a plastic housing, you must solder the screen to the
metallic frame of the connector.
At any time you must be sure the screen gets a proper contact to the front fascia of the unit
when connected to the controller.

c. When encoder cables are interrupted by terminal boxes or intermediate connectors on their
way from the controller to the encoder, you must connect the screen to the Minus wire of
the encoder supply there, but never to earth potential again!

d. When the cable arrives at the encoder site, the screen must again be connected to the
Minus wire of the encoder supply, but not at all grounded to earth. In general, there are two
types of encoder connections:
Make sure the screen of the cabels is
connected to the Minus supply of the
encoder, but does not touch the metallic
housing of the connector.

e. With all other cables like analogue output, control or parallel output, put the screen to
the metal connector housing on the FS150 side and leave it unconnected on its peripheral side.
Again avoid double earthing. The only place where the screen is earthed must be the front

All cables connected to the FS150 should be separated from motor cables and other power
lines. It is indispensable to use screened motor cables.
4.1. Encoders
The unit only accepts TTL impulse signals (5V, RS 422 ) or similar from an encoder simulation
(resolver). It is essential to connect the channels A, /A, B, /B: The index inputs Z, /Z are not
used with this application.
Where you find you are working with existing 10 - 30 Volt encoder signals which feature only
A, B, Z signals, the PU 210 converter should be used to gain full complementary signals in line
with RS 422 standards.
An auxiliary voltage of 5,2 V (max. 400 mA) is available on the connector plugs “Master“ and
“Slave“, for easy supply of the encoders. Both connectors on the unit are Sub - D - 9 pin, male.
Fig. 10 and Fig. 11 show the encoder connections and the principle of the input circuit. All
impulse inputs are isolated by high speed optocouplers.
When connecting the encoders it is not too important to wire the A and B signals to produce
the correct counting direction. The direction can be determined in the setup menu.

Important
With encoders, supplied by the FS150:
Connector pins 4 and 5 provide the encoder supply.
With encoders, supplied by an external source, or when an encoder simulation from
the drive is used (Common GND operation)
Use connector pin 5 as common zero Volt potential.
For fully potential-free operation:
Connect only A, /A and B, /B and leave terminal 5 ( Common ) unconnected.
For reason of best noise immunity, we recommend to use potential- free operation wherever
you have line driver signals with remote supply.
You must ensure that no external voltage is applied to pins 4 and 5 as this can
cause serious damage to the unit!
Where you use one common encoder for feedback of the drive and feedback for the
FS150 at the same time, there may come up interference problems. You can use a
GV150 impulse splitter to eliminate any kind of problems. In most applications, the
common encoder would also work fine when it is supplied by the drive and the FS150
operates in fully differential mode like shown.

DIL switches S1 / 5 - 8 provide the selection of the encoder edge counting. It is possible with
complementary signals to count with times 1, 2, or 4 without any fear of miscounting. The
selection always applies separately to the master and the slave input signals.

Please note, that
The maximum frequency of the FS150 refers to the total number of edges counted, i.e.
300 kHz (x1) or 150 kHz (x2) or 75 kHz (x4).
Impulse numbers, to be entered upon setup, also refer to the total number of edges
counted, i. e. the entry data must be doubled with (x2) etc.
When possible, you should set the switches in a way to produce approximately similar
impulse numbers on Master and Slave side to achieve best operation. i.e. 4096
impulses x 1 on the Master side and 1000 impulses x 4 on the Slave side. The cross
section of encoder cables must be chosen with consideration of voltage drop on the
line. The FS150 provides a 5.2 V encoder supply and at the other end the encoder must
at least receive its minimum supply voltage! (See encoder specifications).
4.2. Analogue Output
The analogue connector (Sub-D-9 female) provides several auxiliary lines that are not
applicable with FS150 functions. The only pins that must be connected are pin 2 (GND) and pin
7 (output). The cable must be screened and the screen must be connected to the connector
housing on the FS150 side. The screen must be unconnected on the drive side!

4.3. Power Supply
The FS150 operates from an unstabilized 24 VDC supply (+/- 25%), however, the voltage
including ripple should not exceed the following limits (18 V...30 V). The supply of the FS150 is
both electrically and mechanically protected against wrong polarity misconnection by
protection diodes and a special plug.
At pin 1 of the "PI" connector and pin 1 of the "PI/PO" connector, a +24V output
is available for easier wiring of input and output supplies. This voltage is taken
from behind of a current limiting resistor. Short circuiting these outputs to GND
can burn the resistor or internal printed lines.

4.4. Parallel Interface (PI)
The interface provides remote setting of operational and configuration registers. It receives
BCD or binary data (selectable) from a remote thumbwheel switch or PLC control. There are
three binary coded select lines which provide 8 addresses being accessible, via 20 data lines.
The register parameters are stored in the following manner:
a. Read and activate parallel data upon a strobe pulse. The data is then transmitted to the
internal RAM and activated immediately.
b. Store the data to the EEprom by a Store pulse, when you like the unit to use same data
again after power down.
It is easy to see how 8 external registers may be loaded into the FS150. For operation of Read
and Store inputs see section 4.5.
The connection of the parallel interface is a 25 pin Sub-D connector (male) which is marked as
"PI" on the front fascia.
All inputs are PNP switching and fully PLC compatible. All signals refer to GND and the minus
potential of the supply.

FS15016C_e.doc / Nov-15 Page 15 / 59
Important Advice
Upon power up, the unit loads the full register set stored in its EEProm. Data
transmitted from the parallel and/or serial interface will overwrite the
operational RAM data, but not the corresponding EEProm registers. As a result,
when powering up, any parallel or serial data will be replaced by EEProm data,
until it is overwritten again.
The RAM data however can be restored to the EEProm at any time by parallel or
serial command.
Parallel interface operations must keep the following timing conditions:
Data valid
T1 T2 T1 min. = 5 msec.
T2 min. = 5 msec.
BCD data
Read pulse
Fig 16
Data latch occurs with the positive transition of the strobe pulse. Data lines must be in a valid
state at least 5 msec. prior to the strobe, and remain present for an additional 5 msec. while
the data is read. There is no upper limit for T1 and T2.
Mostly the parallel interface is used to preset the cutting length by a simple remote BCD
thumbwheel switch or by a PLC parallel output. The select lines S1-S3 allow to preset also
other registers like shown in table above. Registers are described later in this manual.
Pin 3 of the PI parallel interface provides a special control function:
A “virtual line axis“ can be switched on by this pin, allowing to fully operate all carriage
functions without material and with the measuring wheel in standstill. This is useful for testing
and commissioning. More details are to be found in the section “Virt. Line“.

Inputs
Description
Reset (13):
When set High, a new initializing cycle is started and error messages will be
cleared. Reset does not affect any carriage position counters or batch
counters.
Jog forward
(25)
Jog reverse
(12):
Moves the carriage in one or the other direction (Jog speed register
settable). The carriage automatically stops when it reaches one of the
software limit switches (Minimum or Maximum position). Jog inputs are only
active when the Start/Stop input is in stop state. The software limit switches
do not operate while you keep the “Teach Zero“ input high. Whenever the
Jog command is released, the shear will be electrically hold in its new actual
position and start from there to execute the next cut.
Read and
activate data
(24):
Reads data from the parallel interface and activates new data in the cutting
process.
Start gap (11):
Upon completion of the cut it is possible to shortly accelerate the carriage, so
the tool will shift forward the material and make a gap between. The size of
the gap is register settable and an output will signal when the gap is
completed. Leave input unconnected when gap function not used.

FS15016C_e.doc / Nov-15 Page 18 / 59
Inputs
Description
Cut completed
(23):
This input must receive a signal when a cut has been completed. The
direction of the signal (High/Low) is register selectable. With the selected
edge the FS 150 will start deceleration and reversal in order to put the
carriage back to its rear home position. Each cut completed signal will
increment the batch counter.
Store EEprom
(10):
A High signal on this input will store all register data to the EEprom. Data
which have been transmitted by the parallel interface will be lost after power
down, unless this input has been activated prior to power down. The EEprom
has a limited number of 100.000 store cycles during its life time.
When low, the automatic cutting cycle will be interrupted, but the Jog
functions and the Immediate cut input will remain active. When high, the
carriage will continuously execute cutting cycles according to the preset
length.
Immediate cut
(9):
A positive edge at this input will immediately start the shear for a cutting
cycle, independent on what the actual length is. The subsequent cut will
correspond to the preset length again, unless a Flying Cut has been triggered
again.
This function i.e. allows the operator to cut out bad parts of the material.
Immediate cut commands will increment the waste counter.
Length select
/ print mark:
This input provides a double function:
With Mode 1 (normal operation without print mark), this is a length
selection. Since the unit stores two cutting lengths (Length 1 and
Length 2), a low at this input selects Length 1 to be cut while a High at
this input selects Length 2.
With Mode 2 (operation with print marks), this is the input for the sensor
or photocell detecting the print mark.
Set Zero
position (8):
This input allows to define the “Zero“ position of the carriage. The internal
carriage position counter is Reset to Zero while this input is High. All
limitation settings and alarms refer to this zero position. Please note that
upon power up the carriage position counter will be cleared also, and the unit
would take any actual position as a Zero position. Where you power the
controller down while the carriage is not in at Zero, or where you move the
carriage with the controller in powerless state, it is always necessary to
redefine “Zero“ after power up by a positive signal to this input.
Decrement
batch counter
(20):
The unit provides an internal batch counter incrementing by one with each
cut. If for any reason one cutted piece cannot be used (waste), the counter
can be decremented by a positive edge to this input, to match the real
number of usable products.

FS15016C_e.doc / Nov-15 Page 19 / 59
Outputs
Description
Ready (5):
A high signal indicates the unit is ready to operate and a low signal indicates
the unit is out of order or an error has been detected and the unit has
switched off the control loop (see “Errors“). When high, the unit could not
detect a fault by itself, but this is not a guarantee that the whole system is
ready to work.
Reverse (17) /
Forward (4):
Where you use a carriage drive with only positive speed reference and digital
forward/reverse select, these two outputs will control the direction of
rotation. The output goes High when the corresponding direction is required.
This output generates impulses proportional to the line motion with scalable
length units. As an example, it might be used to totalize full meters of
material passing through, by a separate counter or PLC.
Carriage
position alarm
(3):
This can be used to limit the travelling way of the carriage into forward
direction during production.
If, i.e., for mechanical or other reason, the carriage could not synchronize with
the line, the controller would never generate the „“Ready to cut“ signal and
the carriage would run to the front detent. The alarm position is register
settable and this output switches High to indicate the carriage will run out of
range if not braked down immediately.
Carriage home
(15):
A high state of this output indicates the carriage is in its home position like
defined by register “home window“.
Gap complete
(2) :
When the gap function is used, a high signal indicates that the gap has been
executed and the controller now waits for the “cut completed“ input.
Ready to Cut:
This output goes High when the shear has reached its cutting position with
respect to the material and moves fully synchronous with the line. See
parameter "Cut window". It goes Low again when the shear signals "Cut
completed".
Important remarks:
1. When for any electrical or mechanical reasons the carriage cannot reach
the proper cutting position or cannot synchronize with the line speed, the
"Ready to Cut" signal will never switch on and the carriage could run to its
front detent without executing a cut! Use the Carriage alarm output and
mechanical safety switches to avoid damage.
2. Each cut must be followed by a "Cut completed" signal, otherwise no
reversal of the carriage will take place and it will run to its front detent!
For tests (with saw blade or shear removed) it is legal to connect the
“Ready to cut“ output to the “Cut completed“ input.

6. The Serial Port
The RS 232 serial link can be used for two purposes:
The unit includes a serial RS232 and a RS485 interface, both accessible by the Sub-D-9
connector marked „RS232“.

Please make sure your PC serial cable uses only the three pins shown. When also other pins
are connected, this will cause interference with the RS485 pins and the PC communication will
not work.
When using the RS485 interface, you can serve up to 32 different bus participants in either
2-wire or 4-wire transmissions mode. The subsequent figures show, as an example, how to run
a TX720 operator terminal with a FS150 unit and other controllers.
