2. Operating Pinciples
Diagram: Principles of a Cam Switch Unit
A principle for better comprehension of the function of a Cam Switch Unit is here presented. It has 3
outputs with the following cams:

The positions of the output signals, here presented as three tracks, occur when the three cam disks
turn anti-clockwise past a sensor, which scans the cams on the 0°-axis.
In a mechanical cam switch unit, the switch interval, i.e. the range between switch-ON and switch-OFF
position are determined by the length of the cam. The length and the position of the cam can only be
varied marginally and this is mechanically highly demanding and time consuming. With CamCon such
adjustments can be realised in a fraction of time; in addition, there can be any number of tracks. A
measuring system which is fitted to the device reports the position to the CamCon. The CamCon
compares it with the programmed switch-ON and Switch-OFF positions of all outputs. If the position
lies in the range of a programmed switch-ON / switch-OFF position (cam), then the respective outputs
are active.

2.1. Speed Compensation
Each mechanical switch component (e.g. shield, magnetic valve) has a delay time, i.e. the time
between the start signal and the actual switching of the contacts. In processes where positioning is
executed on a moving system, this can cause problems. If such a process is driven with different
speeds, different positions are caused. To avoid this happening, new timings for the switch signals of
each speed would have to be calculated.
In order to ilustrate the complicated issues surrounding delay time or speed compensation, this will be
shown on the example of a packaging machine. In the process shown in the diagram, a glue point has
to be placed in an exactly defined spot on a moving paper track.
magnetic valve
The system has the following parameters:
CamCon
vp
vT
d
glue nozzle
-
encoder
drop
TMV paper
Speed of the paper track
Falling speed of the drop of glue
Distance between the glue nozzle and
the paper track
Delay time of the magnetic valve
paper track
Points where the glue
hits the paper at the
different speeds
.
Without speed compensation the following would happen:
As soon as the measuring system has reached a certain position, the CamCon sends a signal to the
magnetic valve. The glue nozzle opens for a short time during which a drop of glue ejects. Between the
start of the impulse and the exit of the drop time passes, which is mainly caused by the delay time of
the magnetic valve TMV.. A further delay is caused by the time which the droplet needs to pass the
distance between the glue nozzle and the surface of the paper.
This flight time is calculated as follows:
d
tFlight = v
T
In total there the delay time is tFlight+TMV. During this time the paper track moves on by a specific
distance x.
It would now be possible to move the position, where the magnetic valve is switched on, forward by a
specific amount, so that the glue droplet hits the same spot again as during standstill. In this way a
speed compensation is created which works only at a specific speed of the paper. As soon as the
speed of the device and consequently that of the paper track is, for example, doubled, the hit point of
the glue droplet is shifted by the distance x, so that, without any speed compensation, it would move
backward by double the distance (2 ⋅ x) in total.
The automatic speed compensation of the CamCon makes it now possible to drive processes with
variable speed; CamCon registers the speed of the device continuously and adjusts the cams which
determine the switch time points "On Line" depending on the speed. This has the effect that the
outputs for the switch components are switched ON or OFF earlier. The direction of the movement is
of no significance in this instance.

A small example in figures was designed to eludicate:
Supposing the drive cylinder with the measuring system has a circumference of 360mm, so that one
millimeter of the circumference corresponds to exactly one angle degree of the measuring system.
The device has the following parameters:
vdroplet
d
TMV
=
=
=
20m/s
20cm
20ms
This results in the following flight time of the droplet:
d
0,2m
tFlight =
=
10ms
vT
20m/s =
The total delay time is then Tdead, altogether = TMV + tFlight = 20ms + 10ms = 30ms
During this time the paper track moves on by the distance x = vpaper ⋅ Ttotal delay. = 1m/s ⋅ 30ms =
30mm. In order to compensate the delay time, the switch point for the magnetic valve must be moved
forward by 30°.
If the speed of the device and consequently that of the paper is doubled vpaper, then the distance x is
also doubled by the speed of the paper track. In this case the switch point must be moved by 60°.
Note:
Please take into account in these explanations that delay time is of a fixed size, which is
determined by the mechanical constants of the set and switch components and by the
dimensions of the construction and therefore does not change!
If the total delay time of 30ms was programmed into the respective output of CamCon, then the glue
droplet would always hit the right spot, regardless of the speed.

2.1.1. Measuring delay time for Speed Compensation
Several ways of measuring delay time of a relay or valve are available.
2.1.1.1. Measuring delay time through actual differences
First the switch-ON point of a valve or relay is programmed. We assume that the programmed switch
point lies at 200 degrees in this case. If the machine is driven with a speed of for example 40 rpm, a
shift occurs due to delay time. This shift is then measured and, in this example, will amount to 40
degrees.
Warning:
For the calculation of the shift the programmed delay time in the cam switch unit must be
set to zero!
The delay time of the switch component is now calculated as follows:
∆ way (in °) * 60 (sec./min.)
Delay time ( in sec. ) = speed (in rpm) * 360 (°/turn)
40 * 60
Delay time ( in sec. ) = 40 * 360 = 0.1667 sec.
The resultant delay time is then entered into the cam switch unit.
See Chapter "7.3.3. Programming the delay time" an page 33.
2.1.1.2. Measuring delay time by means of different measuring points
First the switch point is calculated at a speed of, for example, 50 rpm. We assume that the
programmed switch point lies at 200° in this case. The second measurement is taken at a speed of 80
rpm The necessary switch point must be set to 160°, if the exact switch point is to be also achieved at
80 rpm.
Warning:
For the calculation of the two switch points the programmed delay time in the cam switch
unit must be set to zero!
The delay time of the switch component is then calculated with the following formula:
Delay time ( in sec. ) =
∆ way (in °) * 60 (sec./min.)
∆ speed (in rpm) * 360 (°/turn)
40 * 60
Delay time ( in sec. ) = 30 * 360 = 0.222 sec.
The resultant delay time is then entered into the cam switch unit.
See Chapter "7.3.3. Programming the delay time" an page 33.
Since the entered delay time shifts the switch point, the previously programmed cam must be changed.
For the calculation of the exact switch-ON position, the difference to the speed O rpm (here using 50
rpm) must be added to the first measured switch-ON point (here 200°). The difference is calculated
with the following formula:
∆ way (in degrees) =
dead time ( in sec. ) * ∆ time (in min-1) * 360 (degrees/rotations)
60 (sec./min.)
∆ way (in degrees) =
0.222 * 50 * 360
= 66.6 degrees
60
The switch-ON point of the cam is now shifted from 200° by approx. 67° to 267°.

2.1.2. Speed Compensation using off-centre pressure, e.g. brake functions
The Speed Compensation of the CamCon Cam switch unit works using a linear function. If, for
example, the speed doubles, then the shift of the compensated cam changes and also moves forward
by twice the amount. If the ram on an eccentric press should be brought to a standstill at the exact
upper stop point, the brake action of the press under different speeds results in a quadratic function.
The Speed Compensation can therefore only find an approximation of the exact switch point for the
stopping of the press by adjusting the line of the cam lines to the brake curves in the working range of
the press.
In the graphic on the right the curved line represents the
brake point of the ram in relation to the speed.
For the calculation of the parameters to be programmed
please proceed as follows:
-
Define the working range (e.g. 20-50 rpm) and determine
two measuring points which have to be specified in the
working process (e.g. 30 and 40 rpm).
-
Now let the machine run at 30 rpm and program or
optimise a cam without Speed Compensation so that, at
switch-OFF, the ram comes to a halt in top stop. Note the
switch-ON point of the cam (e.g. 340°).
-
Now let the maching work with 40 rpm and program or
optimise one cam without Speed Compensation so that,
at switch-OFF, the ram comes to a halt in top stop. Once
again, note the switch-On point of the cam. (e.g. 332°).
-
Now calculate the delay time, taking into account the
distance and speed difference, using this formula:
Delay time ( in sec. ) =
U/min
Verlauf
Nocke 1
Nocke 2
∆ way (in °) * 60 (sec./min.)
340-332 * 60
= 40-30 * 360 =
∆ Speed (in rpm.) * 360 (°/turn)
0.133 sec.
-
The calculated delay time is now entered into the cam switch unit.
-
Since the switch-OFF point has shifted through the entered Speed Compensation, the previously
programmed cam must be changed first. For the calculation of the exact switch-ON position, the
difference to the speed 0 rpm (here 30 rpm) must be added to the first measured switch-ON point
(first measuring point here 340°) The difference is calculated with the following formula:
∆ way (in °) =
-
delay time ( in sec. ) * ∆ Speed (in rpm.) * 360 (°/turn)
0.133 * 30 * 360
=
= 23.94°
60 (sec./min.)
60
The switch-ON point of the cam has now shifted from 340° by approx. 24° to 364°.
As a result a cam with a switch-ON point of 4° and a speed compensation of 0.133 sec has been
calculated. This is entered in the cam switch unit as switch-OFF cam of the press.
Note:
If the degree of accuracy is no longer sufficient when switch-OFF is done with one cam, two
or several outputs can be switched in parallel and the cam of those is then adjusted to the
required working range. For the calculation of two switch-OFF cams divide the working
range in 5 parts with 4 measuring points and then calculate the delay time value and the
cam value with the same formula as described above. For the calculation of the first cam,
use the measuring points 1 + 2 and for the calculation of the second cam use the
measuring point 3 + 4.
Through this association of the linear cam functions to the brake functions it is now possible to switch
OFF the cam via the entire working range of the press in the top stop.

2.1.3. Separate delay time for Speed Compensation of switch-ON and switch-OFF points
For CamCon devices of Software from 3/2002 Speed Compensation is now available for separate
switch-ON and switch-OFF points. This is necessary since some valves need longer to switch OFF
than to switch ON.
Switching attitude of a cam programs from 140° to 200° with 60 min -1.
Cam with 111ms Speed compensation for switch on point and 166ms
compensation for switch off point.
Cam with 111ms Speed compensation.
Cam without Speed compensation.
For the calculation of both delay times the same formuli are used as for a normal compensation. See
Chapter "2.1.1. Measuring delay time for Speed Compensation" on page 11 for entering delay time see
Chapter "7.3.3. Programming the delay time" on page 33.
Attention: If the switch-off-point of a Cam overtakes the switch on point at rising speed, the result will
be an non-defined signal.
2.2. Time - Cam
With nomale cam becomes with increasing plant speed switch-on time ever more briefly. If controlling
a glueing-station, the result would be an insufficent ammount of spreaded glue.
A Time - cam however has with each plant speed a firm temporal length, so that excactly the same
ammount of glue could be spread at changing speeds. The switch-on point of the Cam on a normal as
well as on a Time-Cam is appointed by a position-dependent Position value and a delay-time/speed
compensation.

4.1.8. Pin allocation of the external interface
If you ordered the external interface along with the CamCon, you have the possibility to extend your
CamCon by a CamCon DC91/IO, DC92/I or DC16/IO. The extensions are clipped on to a rail in the
clipboard. They are connected with a cable with 6 poles, type "KK91/IO-XX" with the 9pole D-Sub male
plug "external Inter in" at the CamCon module (maximum cable length is 300m). The data transfer is
done through optical couplers, so that the connection remains potential free.
For the CamCon DC16/IO a DSUB cable with flatwire adapter can be ordered, order No. "KK50-16/IOXX" (Note: XX refers to the cables length in meters).

4.2. The measuring system
The measuring system is designed to record the necessary actual values (positions) for the Cam
Switch Unit. Many different measuring system can be linked with the CamCon.
See chapter "4.1. Pin allocation" on page 15 and for adjustment of the measuring system to the
software of the CamCons please also consult Chapter "7.4.1. Measuring system" on page 45.
Note: Please also consult the instruction manual for your measuring system.
4.2.1. SSI Measuring system input
Systems with a synchronous series interface = SSI. The SSI interface is widely used in industry for
absolute single and multi-turn angle encoder. At this interface the CamCon supplies the measuring
system with 24Volt. For the purpose of data reading the CamCon sends a stroke signal (clock) with
RS422 level to the measuring system. This answers synchronously with the data output of the position
in the grey code. The frequency of the pulse signal depends on the length of the cable to the
measuring system and can be set in the CamCon.
Note: The data record corresponds to the Stegmann SSI Standard!

4.2.2. Parallel measuring system input
Systems with parallel 24V data leads, e.g. single turn - angle encoder or via a transformer with parallel
data output.
In this instance a gray or binary encoded value is attached to the free inputs of the CamCon and this
will be read as actual value. Since the connection cable are quite expensive and the EMV compatibility is limited, this interface type is rarely used in industry nowadays.
Note:
Since the outputs are partly switched parallel to the inputs in CamCon DC16, DC115,
DC300 and CamCon 1756-DICAM, these must not be programmed under any
circumstances and this reduces the number of available outputs.
Warning:
Reading a binary encoded value into the CamCon is only permitted after consultation with
the Service department of the company Digitronic.

4.2.3. Incremental measuring system input
Systems with 90° phase shift signals such as turning angle encoders, glass measuring rods or flow
measuring devices.
At the present time incremental measuring inputs for the CamCon DC16/50/51/115/300 and DC1756
are available as an option. We differentiate between three signal levels:
Note:
24V PNP Signal inputs
5V RS422 Signal inputs
Hiperface Signal inputs
(Order number Option: J)
(Order number Option: I)
(Order number Option: H)
For the CamCon DC16 and DC300 only the version with 24V PNP signal is available. For
the CamCon 1756-DICAM the version with 24V PNP signal and Hiperface Signal is
available. If a different signal level is necessary, this can be converted externally with the
INCDRV converter.
In all cases the CamCon supplies the measuring system with 24Volt/DC or in CamCon DC115
optionally with 5 or 24Volt/DC. As a counting signal the measuring system gives out two impulses at a
time shifted by 90° (A + B). These are counted in the CamCon and are evaluated as position values. In
addition, for each rotation another zero impulse (Clear 1) is given out for synchronisation purposes. In
order to stop synchronisation (zero setting) of the counter, a further clear signal (Clear 2) is available
on the CamCon.
The signals Clear 1 and Clear 2 are to standard AND linked and can be
changed in their function with the software. See Chapter "7.4.1.6.3.
Incremental - measuring system" on page 49

4.2.3.1. Incremental measuring system input with 5V RS422 level
Clear 2
If the 5V RS422 system is used, all signals of the measuring
system input must be active, otherwise the input conditions are
undefined. If no signal is available for one of the two Clear
inputs, then this input must be switched to mass on the (+)
signal in order to switch the input to low. The inputs of the
measuring system can be activated with a maximum voltage of
5V. Please pay attention to the power supply of the angle
encoder which can be 5Volt as well as 24Volt. Only the CamCon
DC115 can at present provide a voltage of 5Volt for the supply of
the angle encoder.
4.2.3.2. Incremental measuring system input with 24V PNP level
If a 24V PNP signal is used for data input, then only the (+)
signals of the inputs may be connected. The (-) signals must
stay inactive in this case. The connection of such a measuring
system requires a change of the interal switch system and must
therefore be stated on the order form.
Note:
At the incremental input of the CamCon DC16,
DC300 and DC1756 no (-) signals are available.

4.2.3.3. Incremental Hiperface measuring system input with SINCOS level
The Hiperface measuring system is a feedback system for servo-motors of the company Stegmann.
It is a mixed system and consists of an absolute measuring system and an incremental measuring
system. The absolute measuring system sends its values via RS485 interface to the counter. The
incremental measuring system works with analog sine - and cosine interface with a resolution of 512 or
1024 impulses per revolution.
The CamCon with the Hiperface signal input
(option: H) reads only the incremental sine - and
cosine signal. The signals are converted and
counted in the CamCon into normal incremental
measuring system signals.
CamCon
Since the absolute measuring system of the
Hiperface interface is not used and no clear signals are available, the CamCon must be
initialized after each restart.
controller
SINCOS
This must be done by the preset input of the
CamCon. See for this to chapter 7.4.2.4. Actual
position preset on page 56.
Note:
The maximum number of
revolutions per minute is 3000 min-1 with 512 Impulse per revolution.
The maximum number of revolutions per minute is 1500 min-1 with 1024 Impulse per
revolution.
4.2.4. Analog measuring system input
These are systems which receive their actual value through conversion of current or voltage signal,
such as temperature or pressure sensors.
For the recording of analog signals the analog to SSI conversion module AWA/SSI in 8 and 12 bit
resolution is available for the CamCon. This module is connected to the SSI of the CamCon and is
switched ON through the selection of the analog measuring system in the menu ”Measuring system”.

4.2.5. PLL measuring system input
Systems with Phase - Lock - Loop data recording. In these systems the actual value is found through
interpolation of initiator impulses. This measuring system is applied to machines with constant speed
and with a cyclic pulse.
= Initiator impulse
= Found actual value
The Initiator can be connected to any free input of the CamCon.
Note:
For CamCon DC115 a special input is available on the 25pol. SUB-D plug.
See also chapter "7.4.1.6.5. PLL measuring system" on page 51.
4.2.6. Timer as a measuring system
Systems which are controlled by elapsed time. In this case the CamCon makes a time available with a
time basis of minimum 1 ms as actual value. Through laying on of input signals it is possible to
influence the elapsed time. This measuring system is applied to machines with a fixed time scanner as
a control feature, e.g. washing machines.
See also chapter "7.4.1.6.6. Timer way simulation" on page 51.
4.2.7. RS232 as a measuring system
Systems, receiving their actual position through the RS232 interface, e.g. for a junction of a Stegmann
POMUX linear scale to a RS232 data output.
Warning
The activation of this measuring system blocks the RS232 interface for
programming. This measuring system is only reasonable with a CamCon
DC50/51.

4.3. The outputs
The CamCon has, concerning each upgrading level, up to 32 outputs and with extreme extension (e.g.
CamCon DC16/IO, DAC16 or DC91/IO) up to 200 short circuit-proof outputs. They deliver 24Volt high
active signals and are not potentially free towards the CPU. The outputs 1 to 16, as well as 17 to 32 of
the unit have to be supplied with 24Volt , because the power supply of the outputs has been separated
in order to achieve a better power distribution.
4.3.1. The 40mA outputs (only CamCon device with aluminium back wall)
If all outputs are activated, not more than 40 mA permanent current in the complete temperature range
should be extracted per output, else the unit will deactivate with an error message. If a higher starting
performance is required, one has to know that the outputs are combined in 4 groups, each group
consisting of 8 outputs. Within each group, 480 mA permanent current at a surrounding temperature of
50°C, and at a surrounding temperature of 25°C even 700mA permanent current is available. This
permanent current can be dirtributed freely within a group, as long as the single output current of 300
mA is not overshot (see chapter "7.4.6.2. Setting the outputs" on page 63).
4.3.2. The 500mA outputs
At a surrounding temperature of 25°C even 500mA permanent current is available for each output. If
your outputs are overloaded or short-circuited the unit will deactivate with an "out-err" message
(see chapter "7.4.6.2. Setting the outputs" on page 63).
Attention: For inductive loads the inductances have to be tripped with a freewheeling
diode.
4.4. The inputs
The CamCon has, concerning each upgrading level, up to 16 inputs and with extreme extension up to
200 inputs. These inputs work with high externally active 24Volt signals and are not potentially free
towards the CPU.
The input wiring:
The input resistance
is about 5.7 KOhm.
The inputs of the CamCon have not been covered with functions by the factory. The user would have
to do this himself in the process of setting system data of the CamCon depending on his requirements.
See chapter "7.4.6. System upgrading" on page 63, chapter "7.4.1. Measuring system" on page 45,
chapter "7.4.6.7. Setting the external program selection" on page 64 and chapter "7.4.6.4. Setting the
keyboard lock" on page 63.
4.5. Precautionary measures for welding work
Attention: For the duration of welding operations carried out at the machine, the
connecting wires concerning the data exchange from the measuring system to
the CamCon and the power supply as well as the grounding connections and
inputs and outputs have to be separated from the CamCon.

6. Commissioning
Before switching the device on for the first time, please check its wiring (see chapter 4.1. Pin allocation
on page 15).
Attention: With induced loads the outputs have to be switched with a freewheeling
diode. Covers or inductivities very close to the device inside the
switchboard have to be switched with a deletion unit as do those that are
wired to or influence the wiring of the device.
After being switched on the CamCon will generate a short tone. Afterwards it will start the internal
review and the running up of the system (e.g. to generate the proof total of the EEPROM and the
EPROM). This process takes several seconds. After a successful installation of the system, the
standard display (the current program number, the position and the speed, as well as a possible error
message) is displayed. Once the system registers are brought in accord to the measuring system and
it is wired correctly, there should be no further error messages.
After first activating the supply voltage, the program memory is not in a defined state. So when first
using the CamCon unit you have to put a complete deletion into operation as follows:
1.
Press the
key, you leave the standard display
and enter the main menu:
2.
Select the menu point "Unit configuration" , the
request to enter your user code is displayed on the
LCD:
3.
4.
Enter your user code. If you have not programmed
your own key, use the standard key number
"5693"!
Press the
key to confirm your user code. If a false code is entered, "Wrong user code!" is
shown on the display. In this case, press any key, and reenter the code. The display returns to
the main menu after about 30 sec., if no numbers are entered or the input is not confirmed with
the
key.
After the correct user code is entered, the display shows
the configuration menu.
5.
Select the menu point "Format unit" , the following
question is displayed:

After about 5 sec. the display returns to the configuration menu. This waiting time depends on the size
of the used EEPROM, since the memory has to be formatted. With the use of a 32k - EEPROM it is
increased to approximately 2 min. After this time the complete deletion is finished. All cams are erased,
all system registers have the standard value.
Now you can begin with the system setting.
To make your device operable, you have to set a minimum number of parameters on your CamCon.
This is the recommended order of the parameterization. You can find the neccessary information in the
corresponding chapters.

(see chapter "7.4.5.7. Configuration of the analog cams" on page 61), the last "normal" output will be
displayed as the first analog output after pressing the

key.
=>
The output numbers of the analog cam outputs are always added to the numbers of "normal" outputs
and this number can be selected directly from the programming menu. If you have configured e.g. 32
cam outputs, the number of the first analog cam starts at the output 33. The output number of the
analog cam changes automatically when you change the number of "normal" outputs (see chapter
"7.4.6.2. Setting the outputs" on page 63).
The programming of the analog cam is mostly done as described in the chapters for "normal" cam
programming (see chapter "7.3. Cam programming"). For analog outputs, you do not program a
position as a deactivation point, but an analog value. If several such values are programmed at
different positions and the measuring system starts to move, CamCon controlls the analog output in
such a fashion, that a curve is done, corresponding with the drawing below.

7.4. Unit configuration (system setting)
Before you are able to use this device, you have to give
it all the information about the parameters of your
measuring system. Select the menu point "System
setting" in the main menu. The display shows the
system setting menu:
7.4.1. Measuring system
When you select the menu point "Measuring system",
the display changes to the measuring system menu:
Here you can configure the measuring system, the
resolution, the electronic gear, the actual position
hysteresis, the rotation direction and the display format
of the actual position, as well as a special measuring
system. Additionally, the menu point "Position:"
always shows the actual position of the CamCon. See
also chapter "4.2. The measuring system" on page 20.
7.4.1.1. The standard measuring systems
The display gives the resolution of the measuring
system in steps per rotation. Generally the CamCon
works with a rotation angle coder that has a resolution
of 360 steps per rotation. In this case a change in the
input value is superfluous. Otherwise the CamCon can
be adjusted to the measuring system with the
and
keys. You can choose between the following
predefined resolutions, that are all in accordance with
common rotation encoders: 256, 360, 512, 1000, 1024,
2048, 4096 and 8192 steps. Should you not be able to set values in higher resolution ranges, it is
because there is not enough memory available. If this is the case you have to extend the memory of
the device. Also, you can configure two analog SSI changer modules, AWA/SSI/8 and AWA/SSI/12, for
the gathering of analog signals. These modules are connected to the SSI port of the CamCon.
Note:
Should you not be able to set values in higher resolution ranges, it is because there is not
enough memory available. You will need to upgrade the memory of your device. See also
chapter "12. Calculation the RAM storage-requirement for" on page 85.
7.4.1.2. The actual position hysteresis
At the menu point "Hyst." you enter the actual position
hysteresis.
This value is needed to suppress the flashing of the
outputs during uneven data gathering. The exact value
can only be determined through experiments, though it
should be as small as possible or always "0". The
hysteresis can be between 0 and 1/4th of the total
resolution, but can never exceed 255 impulses.

7.4.1.3. Controlling the measuring system
The option "Vmax" of the menu enables entering the tolerated steps per cycle of the actual value..
This enables controlling a measure-system.
The required value is calculated of the CamCon's actual cycle-time, the measuring system's physical
resolution und the device's Speed.
Note:
The resolution needs to be a physical measure, e.g. if for a measuring system 4096
Impulses are calculated to 3600 by a (3600/4096)gear, the resolution must be set to 4096.
Example: Cycle time = 0.5ms / resolution = 360 / speed of machine = 180 min -1.
Value =
resolution * plant speed
* Cycle time + margin
60 * 1000
360 * 180
60 * 1000 * 0.5 + 5 = 5.54 ≈ 6
The result is rounded and filled in "Vmax"
If the CamCon detects a step of more than 6 impulses at the actual value an error report "Ist-Err:5" is
shown.
If a zero is filled in here, the controll is deactivated, and a maximum of 9999 is possible.

7.4.1.4. The electronic gear
In the menu point "Measuring system" a factor for a measuring range transformation can be entered.
Through this the physical measuring range e.g. of a rotation encoder is transformed into a new, for the
user effective visible measuring range. Generally this transformation has the relation 1:1. The first
value represents the multiplier of the actual position, while the second value stands for the divisor
through which the result of the previous multiplication is divided. The result of this operation is the
display value. A negative value in the field of the multiplier changes the direction of the rotation of the
measuring system. To switch the algebraic sign press the
Example:
key during the input of the multiplier.
At a full rotation of a rotation encoder with 360 steps per rotation a machine proceeds for
1000mm.
If the display of the position is to be shown is mm rather than in angular lines, you have
reset the gear with the factor 1000 / 360. The display will no longer change in single steps,
since the resolution remains unaffected.
If you choose e.g. 100 / 360, the actual position is calculated down to a proceeding range
of 100. The position display is carried out in cm, but a floating point representation is not
possible.
7.4.1.4.1. Electronically changing the rotation direction
The direction of the rotation of the measuring system is
set at the multiplier of the electronic gear by changing
its algebraic sign. Press the
key during the input of
the multiplier. See the chapter "7.4.1.4. The electronic
gear".
7.4.1.5. The display format of the actual position
In this menu point you can set the format for the display of the actual position.
The three # are the place holders for the number value
of the display. You can enter additional comments and
the unit of the measured value, e.g. mm, cm or inch
with linear systems. See chapter "5.8. Text input" on
page 27. If you want to display a decimal point, you can
insert one between the place holders (e.g.: ###.#mm).

created:
1.
2.
3.
4.
5
Enter the bit number of the resolution of the SSI
measuring system
A resolution of e.g. 500 impulses corresponds with 9
bits.
Now enter the position of the lowest-situated bit
(LSB).
In our example the LSB would be on 9th position. You can get more specific information from the
manufacturer of your measuring system.
Now enter the cut of the measuring system code.
In our example this would be ( 512 - 500 ) / 2 = 6.
Finally you have to enter the position of the SSI - errorbit of the measuring system. With standard
rotation encoders of the firm Stegmann this position is 14. Always transfer a 0 to this position.
Press the
key to confirm your inputs and exit this menu.
Attention: The position of the data bits can be seen in the graphic in the upper part of the display.

7.4.1.6.3. Incremental - measuring system
If you selected "INC" for your special measuring system in
the measuring system input, the following menu is
created:
1.
2.
3.
Enter the value of the prescaler (predivisor) with the
and
keys. The prescaler divides or multiplies
the incoming impulses from the measuring system
with the defined value. The following scalers can be
entered: "*4", "*2", "*1", "/2", "/4", "/8", "/16", "/32",
"/64", "/128", "/256", "/512".
Here the prescaler is set to "*4". This means that a measuring system with a resolution of 500
impulses supplies the device with 2000 impulses.
Now you enter in the field of the resolution the maximum number of needed impulses. This value
is the maximum resolution, that can be evaluated by the CamCon. If more impulses than this
maximum resolution are counted, the CamCon reports the error message "Pos Err:3". In this
case the maximum resolution has to be reset with a higher value or the actual position has to be
set to zero through a clear signal.
In the field "Clear mode" you set the functions for the two extra inputs C1 and C2 with the
and
the
key. Here you have the choice between eight possible functions.
"C1 & C2"
If input C1 is high and C2 is high, the counter is set to zero.

If input C1 is low and C2 is high, the counter is set to zero.
"C1 & /C2"
If input C1 is high and C2 is low, the counter is set to zero.
"/C1 & /C2" If input C1 is low and C2 is low, the counter is set to zero.
"C1 : W"
If input C1 is high, the counter is set to zero.
If input C2 is high, the impulses of the measuring system are no longer counted.
"/C1 : W"
If input C1 is low, the counter is set to zero.
If input C2 is high, the impulses of the measuring system are no longer counted.
"C1 : /W"
If input C1 is high, the counter is set to zero.
If input C2 is low, the impulses of the measuring system are no longer counted.
"/C1 : /W".
If input C1 is low, the counter is set to zero.
If input C2 is low, the impulses of the measuring system are no longer counted
(W = Wait).

7.4.1.6.5. PLL measuring system
If you selected "PLL" for your special measuring system
in the measuring system input, the following menu is
created:
The PLL measuring system determines the way out of
temporal interpolation of a measuring impulse. If you e.g.
have installed an initiator on a rotation plate and want to
determine the current position at a constant velocity
without having to install another measuring system, the
PLL measuring system is the right choice.
1.
2.
3.
4.
5.
6.
Enter the number of steps from initiator impulse to initiator impulse.
Now enter the input of the initiator impulse.
Now you have to enter the number of initiator impulses per total rotation.
Select the input for the clear impulse.
With the PLL measuring system you have the possibility to incase several initiators per total
rotation. To receive a zero point you need a zero initiator that can be hooked up to the selected
input. If you do not want to use a zero initiator, just enter a "0" here.
Then you enter the synchronous window.
If a step error is determined that is larger than the set value, the system enters the asynchronous
mode.
Now you have to enter the output for the synchronous window that signalizes the synchronous
state. If you do not want such an output, just enter a "0" in this line. This output becomes active
after the PLL measuring system has been in the synchronous mode for 16 cycles.
Press the
key to confirm your inputs and exit this menu.
7.4.1.6.6. Timer way simulation (time emitter)
The timer way simulation makes it possible to generate
ways (or time related actual positions) time based and
without the use of a measuring system. The cam switch
unit then behaves similar to the control of a washing
machine. For this option you have to select "TIMER" in
the special measuring system menu and the following
system is set up:
1.
2.
3.
4.
5
First enter the time between the steps. The finest
resolution of the CamCon is 1ms.
In our example we chose 20 ms.
Now enter the total number of steps.
We chose 100 steps for our example, so the whole process will be repeated after 2 seconds (20
ms x 100 steps = 2 seconds).
After this you have to enter the input for the stop signal.
This will enable the time emitter system. A high signal at this input releases the timer, and the
timer is stopped by a low signal. If you do not want a stop input just enter a "0".
Finally you have to enter the input for the clear signal.
With this signal the time emitter system can be reset to 0. A high signal at this output causes the
timer to remain at "0". If you do not want a clear input, just enter a "0" in the corresponding line.
Press the
key to confirm your inputs and exit this menu.

key as before.
At the moment only the data transfer protocol of a Stegmann Pomux 203BCD is available.
The resolution gives the value in which the actual position of the measuring system is moving.
The prescaler (predivisor) divides the resolution to enable the setting of the measuring system in
devices with lower memory.
Press the
key to confirm your inputs and exit this menu.
Attention: This measuring system may only be used on a CamCon DC50/51, since it
blocks the serial interface, making the programming via a PC or a
terminal impossible!

7.4.2. The measuring offset
If you selected the menupoint "Measuring offset" in the system setting menu, the measuring offset
menu appears on the menu:
Here you can indicate, using the
and
keys, wether
your controlling system is a rotatory (e.g. an eccentric
press) or a linear (e.g. a knee lever press) moved
system.
You confirm your input with the
key.
7.4.2.1. Zero offset with rotatory movements
If you have chosen a rotatory movement, you can now carry out the input of the offset
The offset is subtracted from the physical position. This
makes it possible for you to shift the zero point.
7.4.2.2. Measuring offset with a linear moved system
If you have chosen a linear movement, you can now carry out the input of the moving range and the
offset.
At the menu point "Start" you enter the desired begin of
the proceeding range. You even have the possibility to
enter negative values.
The "End" value of the measuring range changes
automatically and determines the total proceeding way of
the measuring system with its position. Here an input is
not possible.
Attention: If the range between start value and end
value is under- or overshot during the way gathering of the measuring system, the
CamCon switches off with the error message "Pos.Err 3".
7.4.2.3. Zero offset with linear movements
If you have chosen a linear movement, you can now
carry out the input of the offset.
In the menu point "Offset" you enter the zero offset of the
measuring system. The offset is subtracted from the
physical position. This makes it possible for you to shift
the zero point.
Note:
If the rotation direction of the electronic gear is negative, the offset must be set to a value
samller than zero (e.g. -359). See chapter "7.4.1.4.1. Electronically changing the rotation
direction" on page 47.

7.4.2.4. Actual position preset
In the measuring offset menu you have the possibility with the rotary system and the linear system to
set the actual position to a new value by creating a new input (preset).
By setting the preset value to zero, you can generate an external zero signal, e.g. to synchronize the
cycle of the machine and the actual position of the CamCon.
When you have entered the preset value, the device
requests the input number of the preset signal with which
the preset is supposed to be initiated. Enter the number
next to the "P-In"-put line.
Afterwards select, using the keys
and
in the input
field "type", the mode of storage of the preset value.
Here you have two possibilities:
- "RAM" storage.
Here the preset value is copied into the RAM memory of the device. This means that after switching
the device off and on again, the shifting of the actual position equals the zero offset or the offset is no
longer available.
- "EEPROM" storage.
Here the shifting of the actual position is copied into the RAM and into the EEPROM memory of the
device, making it safe to shut off the device without loosing your data.
Attention:
You should only store your data in the EEPROM memory, if the triggering of the preset
just occurs rarely and is absolutely required. This is because of the fact that an
EEPROM only has a limited number of writing cycles: 100000). Shooting over this
maximum number of writing cycles leads to the destruction of the EEPROM and the
loss of the program data of the CamCon.
Note:
The preset input will be read in real-time since the software of the 21.5.2002. Therefore, a
synchronisation of a device already running is impossible.
Pressing
you can leave the menu.

7.4.3. The speed adjustment
If you selected the menu "Speed" in the system setting
menu, the speed adjustment menu appears on the
display:
You can use it to optimally adjust the speed of the device
to the speed of the gear.
7.4.3.1. The speed factor
Normally the speed is displayed through the number of
increments or impulses per second, an output of the
measuring system. If you want the speed displayed e.g. in
rotations per minute or in the number of pieces per
minute, you have to enter a randomizing factor.
Example 1:
A rotation encoder with 512 steps supplies 512 increments per minute, which means
that the gear runs with 1 rotation per minute. The CamCon measures 512/60 = 8,533
increments per second.
To receive a display in rotations per minute enter the factor 1/8,533 = 0,1172.
Example 2:
A rotation encoder with 360 steps supplies 360 increments per minute, which means
that the gear runs with 1 rotation per minute. The CamCon measures 360/60 = 6
increments per second.
Enter a factor of 1/6 = 0,16666 to have the display remain in rotations per second.
Note:
The speed factor is influenced by inputs in an electronic gear. Also see chapter "7.4.1.4.
The electronic gear" on page 47.
7.4.3.2. The display format of the speed display
When you have adjusted the speed range with the factor, you can enter the presentation format of the
display, using the
and
keys (see chapter "5.8. Text input" on page 27).
The # symbols are place holders for the displayed value. If
e.g. the highest value is lower than 1000 and only has
three digits, you only enter three # symbols. If you want a
decimal point displayed, just insert it between the symbols
(e.g. : ###.##). Press the
the next menu point.
key, and the curser moves to
7.4.3.3. Range adjustment of the speed display
In this menu point you enter the maximum speed of your gear or the speed of your movement. This
input is used to adjust the speed display.
An input of e.g. 1000 rotations per minute means that at
+/-1000 rotations per minute the maximum analog output
voltage, (100%) +/-10V, is reached.
This scale also applies to the speed bar that is shown in
the middle of the standard display. Its length is the current
speed compared to the entered reference speed in
percent. Furthermore this is the point of the speed where
the standard display switches from the position to the
current speed. This point always lies at 5% of the here
entered value, for 1000 rotations per minute it lies at 50 rotations per minute.

7.4.3.4. Accuracy of the speed display
During operations the speed display usually fluctuates by a certain value. These fluctuations are
accounted for in the measuring priciple for the speed, since it is a scanning system.
In the menu point "Exact" you can limit these fluctuations
to a maximum value. It is a damping through a low pass
that results in a smoothing of the display, which means
that an averaging process is put into operation. The lower
the input value is, the quieter is the speed display. In
practice, you will always find a compromise between the
dynamics of the display and its readability.
Note:
The "Exact" value also corresponds to the speed value, which is provided by an CP16 or
CamCon DC115 of an PLC.
7.4.3.5. Display, Type
If you want to prevent the automatic switching at the 5% of
the maximum speed in the "Display" menu point, you can
select one of the three different display types with the
key and the
"Automatic"
"Speed"
"Position"
key.
At the 5% point the display is switched from the position display to the speed
display. This bar display shows the speed in percent.
Only the speed is shown on the display. The bar display shows the speed in
percent.
Only the position is shown on the display. The bar display does not show the speed,

In addition to the three display types, you can also select
the desired display type through an input. The display type
has to be set to either "Speed" or "Position", and the
number of the input has to be entered in the field behind.
When input is passive, the set display type is displayed.
When you supply a signal, the display changes from
"speed" to position or from "position" to "speed".

7.4.4. Cable length / Cycle time
If you selected the menu "Cable length/Cycle time" in
the system setting menu, the following menu is set up on
the display:
7.4.4.1. The cable length
In this menu point you can set the conduction length
between the SSI measuring system and the CamCon, as
well as between external input or output extensions and
the CamCon, in meters. This is necessary, since the cable length determines the maximum possible
speed of serial data transmission. The larger the set cable length, the larger is the cycle time of the
transmission and the slower is the data traffic. The cable length can be set to a maximum of 1000m.
Attention!! With cables exceeding 300m in length use a corresponding measuring system as well as
extensions with a changed mono-flop-time.
7.4.4.2. The cycle time of the CamCon
Normally the CamCon operates with the shortest
possible cycle time. It is displayed as long as the cursor
is not on the menu field "Cycle time". With an input in
the menu field "Cycle time" this time value can be
changed.
This might become necessary, if e.g.:
you are programming a large number of outputs with
delay time or with a high measuring system
resolution and need longer single delay times. These depend on the available memory and the
cycle time ( see chapter "12. Calculation the RAM storage-requirement for" on page 85). A
noticable change occurs only when the set value lies above the current cycle time. For this reason
the display also shows the maximum possible speed compensation.
you connect a measuring system that allows the readout of the data only once in a given time.
Press the
key to end your input and exit the menu.
7.4.5. The special outputs
If you selected "Special outputs" in the system setting
menu, the special outputs menu appears on the display:
7.4.5.1. The security output
To have the possibility to supervise the CamCon e.g. after
short circuits on the output channels or mistakes in the
measuring system, you can program a circulation cam for
a single output, so that this output is switched off at the occurence of a mistake and serves as a
security output. With a program change, the security output is reset for a short time (see chapter
"7.4.6.8. Setting the program selection mode" on page 64).
A "0" in the input field defines that no security output has been programmed..

7.4.5.2. The output of the actual position
The CamCon offers the possibility to put the physical
actual position out to outputs. It is used when several
CamCon need the same actual position (Master Slave
connection). To be able to use this option, the number of
the programmed outputs has to be lower than the number
of the actually available ones (see chapter "7.4.6.2.

7.4.5.3. Direction output
To be able to recognize the direction of the movement of a
machine with different movement directions, you can
program an output that switches on at a positive and off at
a negative movement.
7.4.5.4. The standstill output
The CamCon offers the possibility of a standstill
surveilance. Here you can define an output that is
switched on when the actual speed is greater than the at
"dir Hyst." entered value and that switches off when the
speed drops below that value again.
7.4.5.5. The hysteresis
To be able to use the options of movement direction surveilance and standstill surveilance correctly,
you have to set the hysteresis. This value is needed to suppress the jittering of the outputs at small
changes in speed. This value can only be determined through experiments, but it should be as small
as possible.

7.4.5.7. Configuration of the analog cams
With a CamCon cam controller you have the possibillity to
make an output of free programmable analog values
(cams) dependent on the position. You enter the number
of analog outputs in the menu point "Analog cams", that
you want to program via the CamCon. In most cases, this
will also be the number of your analog hardware outputs.

, you enter the
Note that CamCon always calculates with an accuracy of
16 Bit. The minimum value is the bit value 0 (e.g. -10V or
4mA) and the maximum value is the bit value 65535
(e.g.+10V or 20mA). The values should be entered
according to the purpose of the device. If e.g. an CamCon
DAC16/I module (current output) is connected to the
external display, the input can be made in milliampere, or the milliampere value corresponds to a
physical preassure - or speed, this value can also be entered in bar or meters per second (see values
in figure above).
Note:
The integrated analog outputs of the CamCon DC40, 50 and 115 all work with an
accuracy of 8 Bit. The output of the analog cam values is recalculated from 16 bit to 8
bit in this case.
After the minimum and maximum values have been confirmed with the
key, the com inputs in the
programming menu are restricted to the range between minimum and maximum and recalculated, if
necessary.
The output of the analog value can be stopped by setting an input to a specific value. For this purpose
enter the input number in the menu point "Dis.inp." (Disable Input), with which the analog value is set
to the "Dis.val." (Disable Value). The "Dis.value" must be within the range of minimum and maximum.
The "Dis.val." is automatically set as a default value, if no cam has been programmed on the analog
output.
When the "Dis.val." is confirmed you can activate ("yes") or deactivate ("no") the interpolation of the
analog value with the keys
and
in the menu point "Interpol.". If this value is set to "yes",
CamCon interpoles the programmed values from definition point to definition point.

7.4.5.8. The analog position output
The analog position output of the CamCon can be programmed with a software version of at least
DC50.20, by the input of an analog cam. Herefore you program an analog cam, that emitts -10V at an
actual position of 0 degrees and +10V at an actual position of 359 degrees (see chapter "7.3.17.

7.4.6. System upgrading
If you selected the menupoint "System upgrading", the
following menu appears on the display:
7.4.6.1. Setting the inputs
Here you can enter the number of inputs available to the
CamCon. This number of inputs should always be exactly
the same as the number of electrical inputs, since the
short circuit detection of the CamCon reacts to the number of inputs.
7.4.6.2. Setting the outputs
Here you can enter the number of outputs available to the CamCon. This number of outputs should not
be greater than the number of electrical outputs, since this only results in a waste of memory and cycle
time. If you want to make an output of the actual position at the outputs, you have to decrease the
number of outputs by the corresponding number of bits (see chapter "7.4.5.2. The output of the actual
position" on page 60.
7.4.6.3. Setting the outputs with speed compensation
Here you can enter the number of outputs with speed compensation available for the CamCon. The
number of outputs should not be greater than the maximum number of the absolute necessary outputs;
otherwise only memory and cycle time are wasted.
7.4.6.4. Setting the keyboard lock
Assigning a +24VDC level to the programmed input pin will disable the keyboard. After this it is not
possible to program or initialize the device any more. Resetting the value to "0" will enable the
keyboard again.
7.4.6.5. Error - aknowledging Input (EQ)
A positive edge (+24V DC)at the inputnumber shown here leads to aknowledgeing an error-notice at
the CamCon "Pos-Error": 1,2,3 and 5 but not an output error"
7.4.6.6. Input for enableling Outputs
A signal (+24V DC) at the input-number shown here enables Cam-outputs, an 0 signal locks
Camoutputs. If this value is set to "0", the "enableling function is inactive and the Cam-outputs are
permanentely enabled.
Note:
Note:
If a PLC-Logic-module is switched on, this effects rather the "0"-outputs but the Camoutputs "N".
Using a CamCon with direct PLC-attachement via CP16 or CP340 respective a
CamCon DC300 and 1756-DICAM, these enableling-functions should be switched off
(0), for the PLC-enableling-function takes on their function.

7.4.6.7. Setting the external program selection
With the CamCon you have the possibility to externally select the desired program number through the
inputs. Here you enter the number of programs that can be selected externally, and this simultaneously
predefines how many inputs will be used for this purpose. Then the input for the take over impulse is
stated. The program number is created as a binary number at the inputs after the take over impulse.
The bit with the lowest value is the input after the take over impulse, all others then follow it in an
increasing order. Because of this the inputs for program selection are completely relocatable.. With an
impulse (+24V) the program is selected at the input of the take over impulse. This impulse has to be
created at least 20 ms after the program number and has to be at least 20 ms long.
7.4.6.8. Setting the program selection mode
You can change programs in several ways. Here you have the possibility to determine the desired way
to change the programs with keys
"slow"
"direct"
"on position"
and
. You can select between:
Here the selected program is built up cam after cam. This type of program changing
requires the least memory, but a complete change of programs during a full run can
lead to complication with the machine. In this case the security output of the CamCon
is switched off for a short time.
Here the selected program is built up cam after cam in an intermediate memory and
changes the full program at once. This type of program changing requires the double
amount of memory for the cam build up, but the outputs are always defined in every
cycle. The security output of the CamCon will not be switched off in this case.
The program is built up in the same way as in the "direct" type, but here the CamCon
waits with the program change until the machine has passed a certain position and
then makes a complete program change. This type of program changing also requires
the double amount of memory for the cam build up, but the outputs are always defined
in every cycle. The security output of the CamCon will not be switched off in this case.

Here you are able to define Cams for different products and programms. They could be necessary if
your plant produces different types of products that have only very little differences concerning their
Cam-adjustement. You are able to save a lot of storage for Cams (EE-Prom), because these
mastercams do not need to be programmed multiple.

Example:
Having adjusted the masterprogramnumber 32767 on and switched output 1 on YES, a Cam in
Program 32767 programed for output 1 will be also editet, if automaticprogram is set to 0. Cams in
Programm 0 programed for output 1 will be ignored though.
To program a Mastercam, switch to menu "programing" and choose your favoured outputnumber. If
you are not in the Masterprogram while putting in Cams, the system automatically switches to
Masterprogram so that you can change a Mastercam.
Note:
In putting in Cams in the "Programing"-menu the only posibility to change Mastercams, if
your logged in with an user key, that has acess to "System config". This disables a user
at the plant to change MasterCams. The procedure of the plant can therefore only be
changed by a person that has the essential acess-key-code.
Note:
If choosing the Masterprogram to program Cams, only MasterCams may be changed.
Note:
If an automatic-program is set on the Masterprogram's number, only the Cams
programed by Masterprogram will be put out.

7.5.3. Unit configuration
If you selected the menu point "Configure unit" in the "Unit configuration" menu, configuration
menu appears on the display:
7.5.3.1. Setting the serial interface
You can select the mode of the serial interface with keys
and
in the input field "Ser.mode", confirming your
selection with the
.key afterwards There are five
different types of operation available : 1. = "Cam-BUS", 2.
= "Standard", 3. = "Multiuser", 4. = "S5-L1" and 5. =
"3964R". When you select a specific communication
mode, you have to make sure, that every connected
device you want to make contact with supports this communication mode. Please note also, that you
can specify the type of serial interface with your order of the CamCon. You can choose between an
RS232 or an RS485 interface. All four "Ser.Modes" operate with the RS232 point to point
communication as well as with the RS485 BUS communication. See also chapter "4.1.7.2. Pin
allocation of the serial RS485 interface" on page 18 and chapter "7.5.3.1.6. Input of the unit number"
on page 70.
Note:
As a standard, the device comes with Ser.Mode set to "Multiuser" and the unit number
set to "0" .
7.5.3.1.1. The "Cam-BUS" communication mode
Select this mode, if you want to be able to program or display CamCon cam controllers from different
places, e.g. you want the CamCon, the daughter display CD10 and the PC via the RS485 BUS.
Attention: Using the configuration above or similar requires that all CamCon devices, as well as any
connected PC be equipped with an RS485 serial interface and a software of at least
December 1996.
7.5.3.1.2. The "Standard" communication mode
The standard mode operates with point to point communication, i.e. you can only connect 2 devices,
e.g. a CamCon to a PC or a CamCon to a CamCon DC50/51 Terminal. Since this communication
mode does not use any protocol security, its usage is only allowed for testing purposes.
7.5.3.1.3. The "Multiuser" communication mode
Contrary to the "Cam-BUS" mode, it is "not" possible to operate several devices, e.g. CamCon
Terminal DC51/T4, the daughter display CD10 and the PC, on the RS485 BUS. (PRESET)
7.5.3.1.4. The "S5 - L1" communication mode
This setting is neccessary, if you want to program the CamCon device via a Siemens S5 CPU. The
process is a point to point communication, i.e. you can only connect the CamCon and the Siemens S5
CPU. If you want to store the data of your CamCon on a PC, you have to brake your connection to the
S5 CPU. For the S5 - L1 communication mode, you can order a connection set compsed of : a TTY
cable, function segments and a handbook (Ordering.No.: PCXX/S5-L1 XX=CamCon Type).
7.5.3.1.5. The "3964(R)" communication mode
This setting is neccessary, if you want to program the CamCon device via a seriell interface with the
RK512 prozedur. The process is a point to point communication.

7.5.3.1.6. Input of the unit number
In the Multiuser and in the Cam-BUS operation, you need to set a unit number for every device on the
BUS. This number can be set under the menu point "UnitNo:" and is then displayed in the main menu
in the highest line on the display. You may only allocate each unit number once for a single linked
RS485 BUS operation. Because of this, you need to set the "UnitNo" and the "Multiuser" or "CamBUS" mode for every device separatly, before connecting the serial interfaces.
7.5.3.1.7. Programming via remote
If you want to program the CamCon from a separat control, you can order a handbook with a
description of the programming sequences (Ordering.no.: H-DC50/PROTO).
7.5.3.2. Additional device options
At the time, the CamCon has the options "PLC", SPS/INFO/HSR and "PLC/INFO" available. If want
your CamCon to be equipped with one of these options, please specify with your order : ("PLC" = S)
("PLC/INFO" = M) ("SPS/INFO/HSR" = C).
These options are described in an extra handbook (H-PLC), which is not in the supply package of the
CamCon.
7.5.3.2.1. PLC Logic Module
The firm Digitronic Automationsanlagen GmbH is an accomplished and well-known supplier and
developper of electronic cam controllers for the industry. The experiences of connecting PLC controlls
and cam controllers, collected in years of close cooperation with the users, have been regarded during
the creation of the PLC Logic Module. The result is a PLC software for the CamCon, that works parallel
to the cam controller. The in- and outputs of the cam controller are linked without external logics or
hardware, e.g. Timers (Way - Time - Cams), Set - Reset - Functions, and registers and can so be
operated within the cycle time of the cam controller. This combination guarantees the best possibility of
using the advantages of the CamCon speed compensation and the logic of the PLC, without the loss of
switching speed because of slow external switching elements (e.g. relays, timers and central PLC
controlls with high cycle time).
7.5.3.2.1.1. Examples for using the PLC logic module
Example 1:
Output deactivation.
Output 1 of the CamCon is cleared if inputs 1 and 8 are active.

7.5.3.3. Analog outputs
The electronic cam controllers of the CamCon series are equipped with analog outputs (CamCon
DC40/50/51 optionally, CamCon DC115 as a standard), via which speed, position or the cam values
can be emitted as analog signals.
Note:
With units CamCon DC16, DC90 and DC300 you can only use the analog outputs by
connecting a CamCon DAC16 digital - analog - converter to the external interface.
7.5.3.3.1. Clearing the integrated analog outputs
At the time, units CamCon DC40/50/51 (optionally) and
CamCon DC115 (as a standard) are supplied with integrated
analog outputs. The outputs are cleared by setting their number
in the menu point "Int.Anlg". The possible numbers are 0,1
and 2. A value of 0 deactivates the integrated outputs.
Note:
Not possible with CamCon DC16 and DC90.
If the value is greater than 0, a line for adjustments appears
below the menu point "Int.Anlg".
7.5.3.3.2. Adjusting the integrated analog outputs
Note:
With units of increment DC51/S5.., DC51/J5.. or DC40/S5.. this feature is neither
necessary nor possible.
The integrated analog outputs of the CamCon have to be regulated from time to time and after the first
activation. Offset and amplification can be adjusted. The maximum analog output voltage is ±10V with
a resolution of 8Bit. Should you wish for a smaller voltage range, you can edit the maximum voltage via
the amplification factor.
Offset output 1
Amplification factor output 1
With keys
and
you can set the amplification and the offset through repeated ajustments with
the keys and measuring the analog output voltage. From analog output 1 to analog output 2 and to
switch between offset and amplification factor, press keys
made, the input is ended with the
,
or
. When all 4 adjustments are
key and the menu is left.

7.5.3.4. Locking EEProm memory
If an PLC-controll writes or programs parameter, Cams or Delay-Times cyclical (eg. DC300 or CP16)
the unit's EEProm-Memory will be destroyed after a short time. If cyclical programming is, for a certain
reason, necessary, you therefore have to lock the EEProm.
Therefore select S-EE in menu "unit configuration" and change it by pressing
to "locked". If the
EEProm is locked, all data will only be written to RAM and will be deleted if the voltage is switched off.
Attention:
After having finished a complete deleting, this value is set to "unlocked" again.

9. Error messages and removal of errors (FAQ)
The error messages appear on the standard display or in CamCon DC16, 90, 115, 300 and 1756DICAM without a display of their own through the status LED or status bits.
The drawing below shows the error message appearing for 'Position - Error 3'.
The display for other errors is almost the same.
9.1 Problem: Display shows "No contact to unit: XX".
Possible causes:
The wiring is probably not correct, no device with the selected unit number is on the BUS or the setting
of the 'Ser.Mode' is wrong.
Solution:
Check the wiring and the configuration of the serial interface.
See chapter "4.1.7.2. Pin allocation of the serial RS485 interface" on page 18 and chapter "7.5.3. Unit
configuration" on page 69.
9.2. Problem: "Pos - Err:1".

9.4. Problem: "Pos - Err:3".
Possible causes:
The resolution of the connected measuring system is not in accord with the input resolution. The
measuring system is faulty. The actual value is outside the range which was entered in the menu path
setting for linear systems. See Chapter "7.4.2.2. Measuring offset with a linear moved system" on page
55. If an incremental measuring system is set, then this report is an alternative for the message
"Clear...".
Solution:
Check the input of the measuring system setting and the cable length setting.
Consult the instruction manual of your measuring system.
Consult Chapter "Problem: Clear...".
If the error is eliminated, the error-message can be deleted by pressing
9.5. Problem: "Pos - Err:5".
Possible causes:
The measuring system control is activated. The CamCon has registered a large unacceptable actual
value jump. The measuring system is possibly faulty.
Solution:
Check the input of the measuring system setting and of the setting of the cable length or increase the
permitted actual value jump. Consult Chapter "7.4.1.3. Controlling the measuring system" on page 46.
Consult the instruction manual of your measuring system.
If the error is eliminated, the error-message can be deleted by pressing
9.6. Problem: An "Pos-Error:" occurs during operation.
The monitor displays "Pos-Err:1", "Pos-Err:2", "Pos-Err:3" or "Pos-Err:5".
Possible causes:
The connection cable of the measuring system or the measuring system itself is defective. A cable
without screening or without dual strand was used. The laying of a connection cable in the vicinity of a
strong electromagnetic source of interference (e.g. high voltage cable, motor cable) can lead to an pos
error.
Solution:
Check the wiring to the measuring system. Replace the measuring system.
Take measures for screening.
Lay the connection lead in another location.
Consult the instruction manual of your measuring system.
If the error is eliminated, the error-message can be deleted by pressing
9.7. Problem: "RAM-Full" = RAM memoryis full.
Possible causes:
The resolution of the measuring system is too large.
The number of outputs is too high.
The number of Speed Compensated outputs is too high.
Solution:
Check the input of the measuring system setting.
Reduce the measuring system resolution.
Reduce the number of Speed Compensated outputs.
Please contact your customer service representative if you require a RAM memory extension.

9.8. Problem: The EEProm memory is full.
Cause:
Too little memory space available in the EEPROM for the storage process.
Solution:
Please contact your customer service representative if you require an EEProm storage extension.
Also consult Chapter "11. Calculation EEPROM cam storage on page 84.
9.9. Problem: Outputs will not activate
Possible causes:
An error message is active. The outputs are not connected to power supply. A programed Cam is to
short or gets to short by increasing rotation speed. The enable - Input is not set.
Solution:
Check the error message.Program a longer Cam. A Cam with delay-time/speed-compensation must at
least have the length of two steps.
Enable Outputs at the enable-Input, see also chapter 7.4.6.6. Input for enableling Outputs on page 63
Enable the outputs through the S5 PLC. Consult your handbook for the S5-L1 linkage.
9.10. Problem: "Out - Error".
Possible causes:
Your outputs are overloaded or short-circuited. Check the wiring and the connection output as well as
possible inductive loads which have no zero setting or are driven by a cancellation component.
The number of set inputs is not correct.
Power failure at an external interface module (e.g. DC91/IO or DC16/IO).
Solution:
See chapter "4.3. The outputs" on page 24.
See chapter "7.4.6. System upgrading" on page 63.
See chapter "7.5.6. Configure Hardware" on page 75.
If the error is eliminated, the error-message can be deleted by pressing
Here the attempt to reset outputs is done
Warning:
Wires crossing behind the outputs, if the cables leading towards the switchOFF of the outputs are in an awkward position, can lead to a switch-OFF of the
outputs, since in an open situation a potential is built up which, when the
contacts are closed, is led back into the outputs.
In inductive loads the outputs must be organised with a flywheeling diode. Protection or
induction in the switch cabinet in the immediate vicinity of the device or due to their wiring
have an effect on the device or its wiring and must be organised with cancellation
components.
9.11. Problem: Error in the EEPROM.
Possible causes:
The data of the EEPROM was changed or destroyed by interference.
One of the existing data carriers (EEPROM or EPROM) was renewed or is defective.
The power supply was switched OFF during alteration of the data.
Solution:
Press
for yes and then the
key. All data will be erased and must be re-entered.
Should these errors occur repeatedly, please contact your customer service.
9.12. Problem: "Error ???"
Possible causes:
An unpredictable error has occurred.
Solution:
Please contact your customer service.

11. Calculation EEPROM cam storage
In the CamCon you have the opportunity to extend the EEPROM Cam storage. The storage space
required for programming is influenced by the following factors:
1. Basic requirement
2. Per cam
3. Per set delay time for Speed Compensation
4. Per name for an output
5. Per set key / code
6. For a special measuring system
7. For direct or ”actual” program selection
8. Per set program name
9. Per line of the OP function
= 256 Bytes
= 12 Bytes
= 12 Bytes
= 24 Bytes
= 66 Bytes
= 66 Bytes
= 12 Bytes
= 48 Bytes
= 72 Bytes
The value is generated by the CamCon with the following formula:
Storage requirements in Bytes
Example 1:
=
+
+
+
+
+
+
+
+
Basic needs
Number of cams * 12
Number of delay times for Speed Compensation * 12
Number of output names * 24
Number of user keys * 66
66 when the special measuring system is available.
12 when "on Pos" program selection is set.
48 * number of set program names.
72 * number of set lines of the OP function.
The Cam Switch Unit is supposed to have 8 Programs each with 16 cams and Speed
Compensation for 16 outputs.
Storage requirement in Bytes = 256 Bytes + ( 8 Programs * 16 * 12 Bytes ) + ( 16 * 12 Bytes )
Storage requirement = 1984 Bytes
Example 2:
The Cam Switch Unit is supposed to have 20 programs each with 16 cams and 16
delay times for Speed Compensation.
Storage requirement in Bytes
=
+
+
+
+
256 Bytes
( 20 Programs * 16 * 12 Bytes )
( 16 TZK * 12 Bytes )
( 16 Output names * 24 Bytes )
( 1 User keys * 66 Bytes )
Storage requirement = 4738 Bytes
Warning:
Through alterations in the storage structure of the CamCon software, the extent to
which storage capacity is used up can differ from software version to software version!

12. Calculation the RAM storage-requirement for CamCon
The required RAM-main storage (not similar to the constand value - Camstorage or the EEPROM)
depends on 7 factors:
1. Standard consumption
2. Number of outputs
3. Cycle time
4. Actual value/measuring system
resolution
5. Maximal Speed-compensation
6. Mode of program selection
(approximately 100000 Byte)
( 8 to 200 in steps of 8 outputs).
(displayed in miliseconds).
(displayed in impulses)
( 0 to 9999.9 in steps of 100 microseconds).
(the double ammount of storage is required ).
( See also chapter "7.4.6.8. Setting the program selection
mode" on page 64).
( EE-Prom - storage size in Byte for Cache ).
7. Size of the EE-Prom storage
The RAM - storage requirement is calculated by the following formula:
storage requirement in Bytes =
standard consumption +
Number of outputs * IActual value resolution.* ( 2 If program Mode not slow )
+
8
max. delay-time * 4
+ EE-Prom size
cycletime
Example 1:
The camswitch with a resolution of 360°, an EE-Promstorage of 32kByte, 16 outputs, a
speed-compensation of 1000ms and a cycletime of 250µs needs:
Storage requirement in Bytes = 100000 +
16 * 360
1000 * 4
+ 0.250 + 32768
8
Storage requirement in Bytes = 100000 + 720 + 16000 + 32768
Storage requirement in Bytes = 149488 = ca. 150kByte
Example 2:
The camswitch with a resolution of 8192°, an EE-Promstorage of 48kByte, 64 outputs,
a speed-compensation of 500ms and a cycletime of 250µs, needs:
64 * 8182
500 * 4
+ 0.250 + 49152
8
Storage requirement in Bytes = 100000 + 65536 + 8000 + 49152
Storage requirement in Bytes = 100000 +
Storage requirement in Bytes = 222688 = ca. 220kByte
Note:
If the required RAM - storage requirement greater than the CamCons total ammount of
storage, you need to reduce the measuring system's resolution.
Attention: Changings in the storage-structure of the CamCon software the storage requirement can
alternate at different software-versions!
