These cutting systems require the horizontal speed of the cutting tool to be synchronous to the
material at any time of the penetration of the tool, whereas outside of the penetration zone, it
is the cutting length and the active radius of the rotation that determine the speed profile.
The subsequent drawing explains the principle of a rotating puncher, the principle of a rotating
shear, and also the geometric basis of the process. It is easy to understand that, during the
penetration of the tool, both applications require an angular correction of the rotational speed,
as soon as the difference between the inner radius ri and the outer radius ro is no more
negligible.

Also it is required to have a smooth profile with no angles and edges, where all values of
acceleration and deceleration are reduced to the possible physical minimum.
As a result of these requirements we find a speed profile as follows:
Line speed
V
L
Speed profile
-1/2 L
0
+1/2 L
(a) (a)(b) (b)(c)
Typical profile of the rotational speed with a cutting cycle at cutting length "L"
Zone (a) results from the ratio between the cutting length and the active rotating circumference
of the tool.
Length > circumference reduces the speed of this zone (with respect to line speed) and may
include temporary standstill.
Length < circumference however increases the speed of this zone. Zone (b) is an over swing
zone, necessary to allow an edge-free transition from zone (a) to zone (c).
Zone (c) is the penetration zone of the tool, and the shape of the profile is ruled by the
geometry of the machine, requiring a reciprocal cosine curve in this situation.
The CT701 firmware continuously calculates an optimized speed profile from the
geometric properties of the machine with consideration of actual cutting length
and momentary line speed.
Very short control loop cycles combined with the smart algorithms of profile
calculation provide excellent accuracy, efficiency and performance.

CT70104B_e.doc / Nov-15 Page 9 / 29
4. How to use the operator software
The OS5 software uses a clear structure of register cards and the contents automatically adapt
to the firmware of the controller.
4.1. I/Os (Inputs and Outputs)
This register card shows the logical state of all digital inputs and outputs.
4.1.1. Inputs
Inputs which are in use for the current application are marked with text, and unused inputs are
marked with “Command …” only.
Indicator boxes in the column marked “X6” shine blue, when the associated input signal on
screw terminal strip X6 is HIGH. LOW state is white.
Indicator boxes in the columns marked “RS” shine blue when the associated input signal has
been switched on via serial link. White box means “signal off”. You can switch on and off every
input from your PC by clicking to the corresponding indicator box in the “RS” column.
Indicator boxes in the column “BUS” shine blue, when the associated input signal has been
switched on via CANBUS. White box means again “signal off”. All input signals follow a logical
“OR” conjunction and the input is in “ON” state when one or several boxes shine blue.
CT70104B_e.doc / Nov-15 Page 10 / 29
On the connector plate of the MC700 hardware, the inputs are accessible via terminals “In1” to
“In16” and the sequence from up to down corresponds to the same layout as visible on the PC
screen.
Meaning and function of the input signals:
= static operation
= dynamic operation, rising edge
Ser/Bus = Activation by serial command or by field bus only.

4.1.2. Outputs
Outputs which are in use for the current application are marked with a text, and unused outputs
are marked with “output …” only.
The indicator box shines red when the corresponding output is HIGH, otherwise the box
remains white. Outputs on the screen appear in the sequence of their mechanical layout on the
connector panel
Meaning and function of the output signals:
Out1
Ready
Indicates that the unit is ready to work after power-up,
initialisation and self-test. This output, however, is not a
guarantee for trouble-free operation of all functions.
Out2

CT70104B_e.doc / Nov-15 Page 14 / 29
4.3.2. Index Settings:
This register card defines origin and evaluation of the index signals
Mode
Currently not used, reserved for future use.
Index Mode
The cutting pulse necessary with every cut (mandatory) and a print mark or
index pulse from the line (optional) can be applied as a HTL/24V signal to
the digital inputs, or as a TTL/RS422 signal to the SUB-D-connector of the
corresponding encoder input:

Slave Index Div.
Impulse divider for cutting pulse. Setting to a value n > 1 evaluates only
every nth cutting pulse
Slave Z Offset
Offset register for virtual displacement of the physical cutting impulse
(generated from encoder index or by proximity). Setting in +/- encoder
increments. This register makes superfluous a precise mechanical
adjustment of the location of the pulse (the virtual cutting pulse must be
located exactly in the peak position of tool penetration)
Time Pulse out
Sets the pulse duration of the 12 o’clock pulse output (x.xxx sec) which the
unit generates exactly in the opposite position of the virtual cutting pulse.
4.3.3. Ramps
This register card is designed for future functions and remains currently unused.
4.3.4. Control Loop
Defines the properties of the closed loop position control:
Gain-Correction
Sets the proportional Gain of the position control loop in relation to
positional errors
Sampling Time
Sampling time of the Master frequency input. Used to smoothen the
analogue output with unsteady input frequencies
Gain Torque
Proportional Gain of the torque analogue output. The torque output voltage
is proportional to the differential error during the cut. When the next cut
begins, the torque output starts with the value that has been stored after
the previous cut. When an error higher than the previous error is detected,
the new value will overwrite the previous value.
CT70104B_e.doc / Nov-15 Page 15 / 29
4.3.5. Jog/Home
This register card specifies the Jog and Homing functions:
Jog Speed
Jog speed for manual movement of the cutter drive
Jog Ramp
Ramp time for acceleration and deceleration when using the Jog function
Home Speed Hi
Fast Homing speed.
Every homing cycle will start with this speed.
Home Speed Lo
Slow Homing speed.
A Homing cycle will end with this speed
Home Ramp
Ramp time for acceleration and deceleration with Homing cycles
Home Switchpnt
Distance from the final home position (scaled in length units) where the
homing speed changes over from high speed to low speed.
4.3.6. Alarms
Settings for monitoring functions:
Min. Master
Frequency
When the real master encoder frequency becomes lower than this set
value, the unit substitutes the encoder frequency by this setting. This
prevents the shear from stopping while the tool is penetrated to the
material.
Max. Analogue
Output
When the analogue speed output signal gets higher than this setting, the
“Speed too High” output signal will switch on.
4.3.7. Diagnosis
Settings for diagnosis functions:
Sel. Diag.
Ana Out 1
Selects the actual value (Process Data) that is put out at analogue output
“Ana Out 1”.
The gain of the analogue diagnosis signal is set by parameter “Ana Out 1
Gain”. When set to 10.00, an actual value of 2048 is repre-sented by an
analogue output voltage of 10 V.
4.3.8. Communication settings
This register card sets the communication parameters for the CAN interface and the serial link.
Settings and operation of the CANopen interface are explained separately in the manual CI700,
which is available on our homepage or on our CD-ROM
The serial link uses the following parameters:
CT70104B_e.doc / Nov-15 Page 16 / 29
Ser. Unit Address

4.3.9. Setup Settings:
These settings define all important hardware properties of inputs and outputs of the MC700
controller.
You must only make settings for these functions that are really used and wired with this
application (see 2.).
Mode Counter
(1–4)
Determines the number of edges counted from the four incremental encoder
inputs:
0 = (x1), 1 = (x2) 2 = (x4)
Dir. Counter
(1–4)
Assigns a counting direction (up / down) to the corresponding encoder
input, depending on the quadrature A/B phase displacement. These
parameters are found out and set best in the Test menu or the Adjust menu
Ana-Out Offset
(1–4)
Sets the zero position of the corresponding analogue output. This parameter
uses a numeric range from
–2047 ... 0000 ... +2047 corresponding to
--100% ... 0000 ... +100% full scale output
Ana-Out Gain
(1-4)
Sets the full scale output of the corresponding analogue output, directly in
volts.
0 – 10,00 means 0 – 10 volts or 20 mA
Ana-In Offset
(1-4)
Sets the zero position of the corresponding analogue input. This parameter
uses a numeric range from
–2047 ... 0000 ... +2047 corresponding to
--100% ... 0000 ... +100% full scale input.
Ana-In Gain

5. Function of the LED indicators
There are 6 red LEDs mounted to the connector plate of the unit, for display of the actual
positional error of the tool position with regard to the scheduled position. The LEDs are scaled
in encoder increments and the update cycle is less than one millisecond. Therefore, this simple
means of error display provides a good information about the dynamic performance of the
control loop.
With hardware version MC720, also the front LEDs operate in a similar way.

6. Steps for Commissioning
For setup and commissioning of all drives, the “Adjust” menu is available under “Tools” in the
main menu of the screen.
At this time, all drives must be adjusted to a proper and stable operation over
the full speed range. Slave drives need a maximum of dynamics and response
(set ramps to zero, switch of any integral or differential component of the
internal speed control loop, operate the drive with proportional speed control
only, with the proportional Gain as high as possible).
Before you start the Adjust menu, make sure that all parameters on the required register cards
are set correctly. Where you find the possibility for integration, please switch it off for the first
steps (set “Int.Time” to 000)
The Adjust Program is used to set the directions of rotation of the encoders and to adjust the
analogue output with regard to the output level and the proportional Gain.
For the adjustment procedure, the Slaves uses always the virtual master axis as
a reference
CT70104B_e.doc / Nov-15 Page 20 / 29
6.1. Preparations
Before starting the procedure, the following settings should be done:
Frequency Preset:
Set the virtual line speed that you would like to use for adjusting. This setting is directly in
Hz of Master encoder frequency and the default value is 10% of the maximum frequency
you have set before (= recommended speed for adjustments).
Ramp Time:
This ramp time is used for all acceleration and deceleration during the adjust procedure.
Gain-Correction:
An initial setting of 500 is recommended.
Ana-Out-Gain:
Start with the default value of 1000 which corresponds to a maximum analogue output of
10.00 volts.
6.2. Directions of Rotation
Move your Master encoder into forward direction (manually or by means of a remote speed
signal)
Observe the counter in the Master column. It must count up (increment)! Where you find it
counts down, please click to the unchecked direction box of the master column (Forward or
Reverse) to change the direction.
When the master counter counts up while the master moves forward, the definition of the
Master direction is o.k.
Click to the “Up” key to start the slave drive.
It is a must that the Counter in the “Slave” column counts up (increments).
Where you find it counts down, please click to the other direction box (Forward or Reverse)
to force it to upwards count.
Once it counts up, click to the “Down” key to stop the drive again. The definition of
direction of rotation has been stored to the unit now
Only when both counters counts up while the according axis moves forward, the
definition of the Encoder direction is correct!
CT70104B_e.doc / Nov-15 Page 21 / 29
6.3. Tuning the analogue output
Start the drive again by clicking “Up”. Now switch the Reset to OFF by clicking to the Reset
key showing actually “Reset On”. This activates the closed loop control.
Observe the colour bar and the differential counter in the field “Differential Error”.
There are two possibilities:
a. The bar graph moves to the right and the counter counts up (+):
The analogue output then is too low. Please increase the setting of “Ana-Out Gain” by
overtyping the figures or by scrolling up with the arrow key.
b. The bar graph moves to the left and the counter counts down (-):
The analogue output then is too high. Please decrease the setting of “Ana-Out Gain” by
overtyping the figures or by scrolling down with the arrow key.
“Ana-Out Gain” is set correctly when the bar graph remains in it’s green/yellow
centre position and the differential counter swings around zero (i.e. +/-8)
You can reset the differential counter to zero at any time between, by cycling the
“Reset” command.
6.4. Setting of the proportional Gain
The setting of register “Gain-Correction” determines how strong the controller responds to
position and speed errors of the drive. In principle, the setting therefore should be as high as
possible. However, depending on dynamics and inertia of the whole system, too high gain
values can produce stability problems.
Please try to increase the setting from 500 to 1000, 1500, 2000 etc. As soon as you find
unsteady operation, noise or oscillation, you must reduce the setting again correspondingly.
We also recommend using the automatic “Cycle” function for observations with stability. When
clicking to this key, the drive will continuously ramp up and down while you can observe the
colour bar and the differential counter.
Once you have done these steps, you can leave the Adjust menu and your machine is ready for
operation.

7. Process data (actual values)
You can follow all real process data assigned to this firmware, when you open the register card
“Process data”. These actual values are updated continuously.
You find a description of the actual process data values in the corresponding table of chapter 9.
CT70104B_e.doc / Nov-15 Page 23 / 29
8. Hints for controller type MC720 with integrated
operator terminal
Controllers type MC720 are equipped with a keypad and a LCD display, providing all entries and
operations of the controller.
Please note that this solution does not support change of parameters “on the
Fly”, but only in standstill.
Also this type is not suitable to replace a PC during commissioning.
8.1. Setting of parameters and registers
All the menu structure of the LCD display is fully similar to the structure of the register cards
with the PC software. To start the menu, press F1. Select the menus and sub-menus by using
the arrow keys nd .Confirm your choice by Enter. With all further actions, Enter will go
forward and PRG go back in the menu structure.
For all operations, just follow the hints given on the LCD menu.
Once you have studied section 4 of this manual, all keypad and LCD operations will be selfexplaining.
8.2. Display of actual process values
During normal production, you can use the LCD for display of interesting actual values and
process data. The PC operator software allows you to define and to scale these values and to
add text comments according to your choice.
The menu “LCD Definitions” can be found under “Extras” of the head line menu.
CT70104B_e.doc / Nov-15 Page 24 / 29
There are totally 4 LCD windows accessible (0 – 3) and the actual window number appears
in the blue head line. To change from one window to another, use the keys “Next LCD
window” or “Previous LCD window”.
Each window allows displaying two actual values with two text comments. The line with
asterisks ******* serves as space holder for the values displayed later on the LCD. When
you click to the text line, you can edit the text comments according to your need (max. 16
characters for each text comment)
Variable Nr: Defines which of all available values should appear in the display. Please
choose one of the 32 available actual values (00 – 31) as shown on the screenshot “Process
Data”
Decimal point: Defines the position where a decimal point should appear on the LCD display
(0=no decimal point)
xOperand, /Operand, +Operand: These 5 decade operands can be used to change the
scaling of your display value to the desired engineering units.
+/-Operand
LCD display
=
register value
x

/Operand

When you have entered your specifications to a window, click to “Transmit” to store your
definitions to the controller.
In production state, you can use the key F2 to switch from one of the four windows to the next
and to read the actual values you have assigned.
Key F1:
Enter into the menu for setting or modifying parameter
Key F2:
Cycle from one window to next to read actual process values
