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 "6.3. The dead time compensation" an page 15.
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 "6.3. The dead time compensation" an page 15.
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°.

3. Installation
The unit is inserted into a cutout for front plate installation (see chapter "3.1. Dimensions" on page 10).
Connect the groundig pins on the back of the encasement as well as the cable cover to a grounding
point of the switchboard door in the shortest possible way. All cable connections must be done in a
cold state! The connection cables, e.g. for the measuring system or the serial interface, must be wired
with covers, and the covers have to grounded on both ends. Analog signals must also be wired with
covers, and the covers have to be grounded on one end.

4.2. The encoder
The encoder is used for getting the actual position, necessary for the cam controller. Only encoders
with an SSI interface can be connected to CamCon DC33/X. The SSI interface is a common interface
for absolute single and multiturn encoders. The CamCon supplies the measuring system with 24Volt
via this interface. To read the data, CamCon sends a clock signal with an RS422 level to the encoder.
The encoder the answers synchronously with the output (data) of the position in Gray code. The
frequency of the clock signal depends on the length of the cable connecting ecoder and CamCon. The
cable length can be maximum of 200 metre.
Note: The data protocol corresponds with the Stegmann SSI Norm.
Tp
= clock impulse
Tmono
= mono flop time 25µs
Attention:
Use only a covered double entwired connection cable. The
wiring should not be near power current lines. Ground the
covers at both sides.
4.3. The outputs
CamCon is equipped with either 8 or 16 short circuit-proof outputs, depending on the version. They
emmit 24V high active signals and are not potentially free. They supply up to 500mA permanent
current in a surrounding temperature of 25°C. If an output short circuits or overloads, the device
switches off with the "A-Err" message.
Attention: With inductive loads the outputs have to be switched with free wheeling
diodes.
4.4. External program selection
The CamCon offers the possibility to select the desired program number externally, through special
outputs. To do this you have to enter the program number as a binary digit at the pins for the external
program selection (pins 28, 29 and 30). With an inpulse (+24V), that has to be entered at least 20ms
after the program number and that has to be at least 20ms long, the program is selected at the input
for the program number transfer (pin 31).
4.5. External activation of the keyboard lock
A signal (+24V DC) at the input for the activation of the keyboard lock (pin 32) disables the keys
and
. This makes it impossible to initialize or program the device.
4.6. Precautions to be taken at welding operations
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 activating the device for the first time, please check its wiring (see chapter 4. Electrical
connections).
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.
6.1. Complete deletion
After the first activation of the supply voltage the program memory is not in an initialized mode. This
leads to the CamCon' s display showing uncomprehendable symbols. That is why you (at the first
activation of your CamCon) have to put a complete deletion into process as follows:
1.
Activate the device (supply with voltage, +24V DC).

key.
After a while (up to 40sec.) the display is reactivated. This completes the complete deletion. All cams
are erased, and all system registers have the standard value.
6.2. Initialization
After an activation of the voltage supply or a complete deletion the CamCon is in the standard mode.
This mode normally displays the rotational speed, the angular position of the encoder, or an error
message. The error message continues to be displayed until the system registers have been adjusted
to the encoder, provided the wiring is correct.
6.2.1. User keys for the system registers
In order to be able to program the system registers, the following key sequence must be maintained:
1.

9. Troubleshooting
Problem:
The display remains dark after activation.
Solution:
The wiring is probably not correct. Check the wiring.
Problem:
The display shows:
.
Solution:
Either the encoder is connected incorrectly or not at all, or the encoder resolution of the connected
encoder does not coincide with the input encoder resolution. Check the wiring to the encoder or the
input of the encoder resolution. When the error is corrected, press any key to clear the error message
of the display.
Problem:
The display shows:
.
Solution:
Your outputs are overloaded or have short circuited. Check the wiring and the connected power as well
as any inductive loads, that are operated without a free wheel or a deletion unit. An output can supply
up to 500mA of current. When the error is corrected, press any key to clear the error message of the
display.
Caution:
Infavourable cable routing can lead to the deactivation of the outputs, since it
builds up a potential that is redirected into the outputs at the closing of a
contact. 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.
