2. Introduction
The CT340 / CT641 units are suitable for control of rotating cutter systems, partial printing
screens and rotating punching or sealing applications.
The CT340 / CT641 units have been designed for the special requirements of these rotating
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.
The units are 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.
The units are suitable for control of cutting applications as well as for partial printing screens
and rotating punching or sealing applications. This manual always says “cutting“ or “cut“ and
the reader may replace this by “printing“, “punching” or “sealing” when applicable.
This manual first provides all basic instructions for operation of model CT340
For operation of relays and thumbwheels with model CT 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.

CT34002a_e.doc / Nov-15 Page 8 / 42
3.1. Power Supply
The CT340 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).
3.2. Auxiliary Outputs for Encoder Supply
Terminals 2 and 18 provide an auxiliary output with approx. +5.2 volts DC (300 mA totally).
Terminals 3 and 19 provide an auxiliary output with approx. +24 volts DC (240 mA totally)
3.3. Impulse Inputs for Incremental Encoders
All input characteristics of the impulse inputs can be set by the parameter menu, for each of
the encoders separately. The unit works with quadrature information (A / B, 90°) only. In theory,
any of the following encoder characteristics would be applicable:
Symmetric differential signals according to RS422 standard, however 1V min. as
differential voltage.
TTL inputs at a level of 3.0 to 5 volts (differential, with inverted signal)
TTL inputs at a level of 3.0 to 5 volts (single-ended) *)
HTL signals at a 10 –30 volts level
(alternatively differential A, /A, B, /B, or single-ended A, B only)
Impulses from photocells or proximity switches etc. providing a HTL level (10 –30 volts)
Proximity switches according to NAMUR (2-wire) standard
(may need additional remote resistor)
*) requires special settings of the threshold parameters, see “Special parameters F08”
For trouble-free operation it is mandatory to use quadrature encoders with
channels A and B or with channels A, /A, and B, /B (90° phase displacement).
Where the impulse level is HTL (10 –30 volts) you can use either single-
ended signals (A and B only) or differential signals (A, /A, B, /B)
Where the impulse level is TTL or RS422, it is strictly recommended to use
symmetric differential signals (with inverted channels /A and /B).
Under industrial environment conditions, single-ended TTL signals may cause
serious problems due to insufficient EMC immunity of the signal lines
All encoder input lines are internally terminated by pull-down resistors (8.5
kΩ). Where encoders with pure NPN outputs are used, corresponding pull-up
resistors must be available inside the encoder or externally to ensure proper
function (1 kΩ... 3.3 kΩ).

CT34002a_e.doc / Nov-15 Page 9 / 42
3.4. Control Inputs Cont.1 –Cont.4
These inputs can be configured for remote functions like Reset, Start, Cutting Pulse, Immediate
cut or display selection purpose.
All control inputs require HTL level. They can be individually set to either NPN (switch to -) or
PNP (switch to +) characteristics. For applications where edge-triggered action is needed, the
menu allows to set the active edge (rising or falling). The Control inputs will also accept signals
with Namur (2-wire) standard.
For reliable operation of the Control Inputs a minimum impulse duration of
50 µs must be ensured. Especially when using the Z marker pulse of a HTL
encoder as cutting pulse, please verify that this minimum duration can be kept
even with maximum speed of the machine
3.5. Switching Outputs K1 –K4
CT340 provides four digital outputs to signal control states like Homing Done, Alarm or Error.
K1 –K4 are fast-switching and short-circuit-proof transistor outputs with a switching capability
of 5 –30 volts / 350 mA each. The switching voltage of the outputs must be applied remotely
to the Com+ input (terminal 29)
3.6. Serial Interface
The serial RS232 interface can be used for the following purposes:
Set-up of the unit by PC with use of the OS32 PC software
Remote change of parameters during operation
Remote readout of actual values by PLC or PC

3.7. Analogue Outputs
The unit provides a voltage output of +/- 10 volts (load = 3 mA), and a current output of
0 –20 mA (load = 0 –270 Ohms), both at a resolution of 14 bits (13 bits + sign).
With most standard applications the voltage output is used as a speed reference signal,
connected to the speed input of the cutting roll drive.

CT34002a_e.doc / Nov-15 Page 10 / 42
4. Functional description
4.1. Principle of operation
When a cutting process needs synchronous circumferential speed of the cutting tool with the
line, the only length that can be cut is the one corresponding to the circumference of the cutting
roll (at constant rotational speed). Change of the cutting length needs exchange of the cutting
roll against another one with appropriate diameter.
The CT340 and CT641 controllers use a two-speed principle featuring full synchronism while
the cut is in progress, but taking a different roll speed when the tool is outside the cutting zone
(where synchronism is not necessary). So, in terms of one revolution of the roll, we are talking
about two speed zones: The “synchronous cutting zone“ (which is register settable) and the
“asynchronous zone“ where the roll follows a speed profile calculated in order to get the
desired cutting length. The speed profile of the “asynchronous zone“ is calculated in a way that
the physically possible minimum of acceleration and deceleration torque is applied to the drive
with respect to actual line speed and preset cutting length.
All speed transitions use self-optimizing S-shape profiles for minimum wear and tear of all
mechanical parts, unless a linear ramp form has specifically been selected by corresponding
parameter setting.
With length settings smaller than the roll circumference, the “asynchronous zone” will take
higher speeds than the “synchronous zone”. With length settings longer than the
circumference, the asynchronous speed will be lower and the drive can even go to a temporary
standstill if necessary. The figure below shows two typical speed profiles:
Cut
V
Line
Sync Zone
t
Cut
V
Line Sync Zone
t
Continuous closed loop control of the relative roll position with respect to the length progress
of the line, combined with a short update time provide best cutting accuracy and exceptional
smooth motion of the cutting roll at any time.
It is a must to use a 4-quadrant drive or a servo drive for the cutting roll, because the CT340 /
CT641 must be able to accelerate and decelerate the roll under real closed loop conditions.
However, no special requirements are necessary for the line drive for full performance.

CT34002a_e.doc / Nov-15 Page 11 / 42
4.2. System Configuration
As a master drive, either the motor of a feed roll or a measuring wheel equipped with an
incremental encoder is used.
The encoder resolutions should be at least 5 times higher than the maximum acceptable
cutting error.
At maximum line speed, the master encoder frequency should be at least about 1 kHz, for best
resolution of the analogue output. Moreover, the input frequency must not exceed the
maximum level of 300 kHz (RS422 and TTL differential encoder) or 200 KHz (HTL and TTL single-
ended encoders).
It is best to choose the ppr numbers of line and cutting roll encoders in a way to produce
frequencies in the same range. Acceptable ratios are in the range of
5:1 ... 1:1 ...1:5
Mismatching beyond 1:16 and 16:1 are not allowed. Where applicable, the (x1), (x2) or (x4)
hardware multiplication of the Master channel or the Slave channel may be used to adapt the
frequencies
The line encoder must be connected to input 1 (Master) and the cutting roll encoder to
input 2 (Slave).
For speed reference of the cutting roll drive the analogue output is used.
The unit must receive a “cutting pulse” with each revolution of the cutting roll. You can use an
external sensor (proximity switch, light barrier) or the zero pulse of the cutting roll encoder, if it
is an HTL encoder and if the encoder is fitted directly to the cutting roll with no gear ratio
between.
Please observe the minimum duration of 50 µs for the cutting pulse!
It is necessary to adjust the cutting roll drive to its maximum dynamic response (no internal
ramps, no integral control loop, high proportional gain), because the CT340 and CT641 will
generate the ramps which the drive has to follow with no additional delay
Two inputs “Jog / Trim” provide manual displacement of the cutting point on the material and
also allow jogging the cutting roll with in standstill.
After power-on or after manually moving of the cutting roll, e. g. by Jog function, you can
perform a homing sequence to move the cutting roll to its home position. When you start the
homing sequence, the cutting roll moves with a register settable speed till the cutting pulse
appears. Then it moves on to the home position, which is located opposite to the centre point
of the synchronous zone.

CT34002a_e.doc / Nov-15 Page 12 / 42
5. Keypad Operation
An overview of all parameters and explanations can be found under section 7.
The menu of the unit uses four keys, hereinafter named as follows:
PROG
UP
DOWN
ENTER
Key functions depend on the actual operating state of the unit. Essentially we have to describe
three basic states:
Normal operation
General setup procedure
Direct fast access to scaling factors
5.1. Normal Operation
In this mode the unit operates to the settings defined upon setup. All front keys may have
customer-defined functions according to the specifications met in the keypad definition menu
F06 (e.g. Display scroll, Immediate Cut or else)
5.2. General Setup Procedure
The unit changes over from normal operation to setup level when keeping the key down
for at least 2 seconds. Thereafter you can select one of the parameter groups F01 to F09.
Setup operation is disabled while the cutting roll is within a cutting cycle.
I. e. the setup procedure cannot be started before the Start command has been
released and the cutting roll has returned to its home position.
Inside the group you can now select the desired parameter and set the value according to need.
After this you can either set more parameters or return to the normal operation.
The adjoining sequence of key operations explains how to change
Parameter number 052 of group F06 from the original value of 0 to a new value of 8

Normal operation
During the general setup procedure all control activities remain disabled. New
parameter settings become active after return to normal operation only.
5.3. Direct Fast Access to Cutting Length Setting
To get to the fast access routine, please press both
and

at the same time
This will access the parameter group F01 right away. To change the cutting length setting
follow the same procedure as already described above.
Besides the advantage of direct access, the fundamental difference to general setup is the
following:
Direct fast access is enabled when the cutting roll is within a cutting cycle.
During the fast access procedure all control functions remain fully active.
Access is limited to cutting length setting; no other parameters can be changed.

CT34002a_e.doc / Nov-15 Page 14 / 42
5.4. Change of Parameter Values on the Numeric Level
The numeric range of the parameters is up to 6 digits. Some of the parameters may also include
a sign. For fast and easy setting or these values the menu uses an algorithm as shown
subsequently. During this operation the front keys have the following functions:
PROG

With signed parameters the left digit scrolls from 0 to 9 and then shows “–„ (negative) and
“-1“ (minus one). The example below shows how to change a parameter from the actual setting
of 1024 to the new setting of 250 000.
This example assumes that you have already selected the parameter group and the parameter
number, and that you actually read the parameter value in the display.

5.5. Code Protection against Unauthorized Keypad Access
Parameter group F09 allows to define an own locking code for each of the parameter menus.
This permits to limit access to certain parameter groups to specific persons only.
When accessing a protected parameter group, the display will first show “CODE” and wait for
your entry. To continue keypad operations you must now enter the code which you have stored
before, otherwise the unit will return to normal operation again.
After entering your code, press the ENTER key and keep it down until the unit responds.
When your code was correct, the response will be “YES” and the menu will work normally.
With incorrect code the response will be “NO” and the menu remains locked.
5.6. Return from the Programming Levels and Time-Out Function
At any time the PROG key sets the menu one level up and finally returns to normal operation.
The same step occurs automatically via the time-out function, when during a period of 10
seconds no key has been touched.
Termination of the menu by automatic time-out will not store new settings, unless they have
already been stored by the PROG key after editing.
5.7. Reset all Parameters to Factory Default Values
Upon special need it may be desirable to set all parameters back to their original factory
settings (e.g. because you have forgotten your access code, or by too many change of settings
you have achieved a complex parameter state). Default values are indicated in the parameter
tables shown later.
To reset the unit to default, please take the following steps:

Switch power off

Press

and

simultaneously

Switch power on while you keep down both keys
Where you decide to take this action, please note that all parameters and
settings will be lost, and that you will need to run a new setup procedure again.

6.2. Description 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.
6.2.1. Length Setting

F02.003
PPR Master:
Pulses per revolution of the line encoder.
Enter the number of pulses from the encoder for one
revolution of the feeding roll or measuring wheel with
regard to the multiple edge count setting (x1, x2, x4).
1 … 999999

F02.006
Trim Time:
Adjustment time for one increment of cut position
displacement with use of the Trim function.
To be entered as number of cycles (1 cycle = 250 µsec)
per increment.
001 = Displacement of one increment each 250 µs
(fast)
999 = Displacement of one increment each 0.25 s
(slow)

Correction Divider:
Function to provide a digital attenuation of the phase
correction signal that is produced, when the drive on
mechanical grounds (dead band or backlash) cannot respond.
In such a case, it is not desirable to make corrections
immediately. The "Correction Divider" provides a window for
the drive "backlash", within which the controller produces no
correction and a division of the differential error count.
0 = No window, Reaction to 1 increment, no division
1 = Window +/- 1 increments, error division by 2
2 = Window +/- 2 increments, error division by 4
3 = Window +/- 4 increments, error division by 8
etc.

Ramp Form:
Selects the shape of the ramps of the cutting roll speed
profile:
0: Parabolic s-ramps
(recommended in general with standard servo drives)
1: Linear ramps
(recommended with less dynamic systems, e.g. DC drives)
2: sin² shaped ramps
(recommended with extremely dynamic servo systems)
0 … 2

F02.009
Sync. Before Cut:
This register defines, how long before the cut (edge of the
virtual cutting pulse) the cutting roll must be synchronous to
the line.
Setting scaled in length units.

F02.010
Sync. After Cut:
This register defines, how long after the cut (edge of the
virtual cutting pulse) the cutting roll must remain
synchronous before the speed profile starts to change speed.
Setting scaled in length units.

Sampling Time:
Sets the internal digital feed forward control with
respect to dynamics and resolution.
Lower set values result in faster response, but less
accuracy of the feed forward signal. Higher set values
result in better accuracy, but slower response with
sudden speed changes.
Feed forward signals with lower accuracy do not at all
affect speed accuracy of the synchronizing process, but
only might cause slight angular errors.
Depending of the maximum Master encoder frequency,
the subsequent setting can be recommended:

Max. Master Frequency:
Sets the expected maximum input frequency on the
Master encoder input, i. e. the line encoder frequency at
maximum line speed. You should add a 10% reserve to
the real maximum frequency. The unit will not process
frequencies higher than this setting.

Cuts per Revolution:
Number of cuts per revolution of the cutting roll.
Set this register to 1 when your cutting roll has only one
tool at its circumference to perform one single cut per
revolution.
When you have mounted two or more tools around the
cutting roll, there are two different ways of setting this
register to perform two or more cuts by every revolution
of the cutting roll:
