2. Introduction
Speed meters of series SD, SA and SR have been designed to close a gap with multiple speed
measuring applications, which cannot be accomplished by normal industrial tachometers.
A continual demand for increasing production speeds and higher precision at the same time
results in counting frequencies exceeding the conventional frequency range.
Particularly with fast running machines it is most important to also get fast response of the
switching outputs or the analogue output.
Many applications require to evaluate the signals of two incremental measuring systems, and
to compare the results with respect to the sum or the difference or the ratio of the two speeds.
The latter is e.g. required to indicate the diameter of a winding roll by sensing the line speed
and the roll rpm.
Other applications with food processing or process technology need to record the speed in a
reciprocal way (i.e. baking or processing time calculated from the actual speed)
And still there exist applications where the use of traditional thumbwheel switches offers real
advantages compared to keypad and menu operations.
These are some of the reasons why the new indicator series SD / SA / SR have been designed.
 This manual at first provides all basic instructions for operation of the
counter models presented in the previous chapter
 For operation of relay outputs and thumbwheel switches (if applicable)
please observe the supplementary instructions given in the appendix
 For easy PC setup and PC communication with SD and SA counters,
please use our “OS32” operator software (free of charge, download from
our homepage www.motrona.com
 Where you like to have free serial access to the unit by PLC or IPC or by a
remote operator terminal, please observe the serial protocol details
described in our separate manual “Serpro”
 Subsequently the manual uses the expression SD340 as a replacement for
all available models. However, statements are fully valid for the other
models too, except where especially remarked.

Page 8 / 60
3.1. Power Supply
The SD340 counter accepts both, a 17 – 40 volts DC power or a 24 volts AC power (+/-10%)
for supply via terminals 17 and 1. The current consumption depends on the level of the input
voltage and some internal conditions; therefore it can vary in a range from 100 – 200 mA
(aux. currents taken from the unit for encoder supply not included).
3.2. Auxiliary Outputs for Encoder Supply
Terminals 2 and 18 provide an auxiliary output with approx. +5.2 volts DC (300 mA totally).
Terminals 3 and 19 provide an auxiliary output with approx. +24 volts DC (240 mA totally)
3.3. Impulse Inputs for Incremental Encoders
All input characteristics of the impulse inputs can be set by the parameter menu, for each of
the encoders separately. Depending on the application the unit can accept single channel
information (input A only without direction signal) or dual channel signals (A = step and B =
direction) or quadrature information (A / B, 90°). The following settings are possible:
 Symmetric input (differential A, /A, B, /B) according to RS422 standard
 TTL inputs at a level of 3.0 to 5 volts (differential, with inverted signal)
 TTL inputs at a level of 3.0 to 5 volts (single-ended) *)
 HTL signals at a 10 – 30 volts level
(alternatively differential with inverted signals A, /A, B, /B, or single-ended A, B only)
 Impulses from photocells or proximity switches etc. providing a HTL level (10 – 30 volts)
 Proximity switches according to NAMUR (2-wire) standard
(may need additional remote resistor)
*) requires special settings of the threshold parameters, see “Special parameters F08”
All encoder input lines are internally terminated by pull-down resistors ( 8,5 kΩ ).
Where encoders with pure NPN outputs are used, corresponding pull-up resistors must be
available inside the encoder or externally to ensure proper function (1 kΩ ... 3,3 kΩ).
3.4. Control Inputs Cont.1 – Cont.4
These inputs can be configured for various remote functions as described under 6.2.4.
All control inputs require HTL level. They can be individually set to either NPN (switch to -) or
PNP (switch to +) characteristics. For applications where edge-triggered action is needed, the
menu allows to set the active edge (rising or falling). Control inputs also accept signals with
Namur (2-wire) standard.
For reliable operation the minimum pulse width on the control inputs should be 50 µsec.
SD34002g_e.doc / Sep-13
Page 9 / 60
3.5. Switching Outputs K1 – K4
SD340 provides four presets and outputs with programmable switching characteristics.
K1 – K4 are fast-switching and short-circuit-proof transistor outputs with a switching capability
of 5 – 30 volts / 350 mA each. The switching voltage of the outputs must be applied remotely
to the Com+ input (terminal 29)
3.6. Serial Interface
The serial RS232/RS485 interfaces can be used for the following purposes:
 Set-up of the unit by PC (if desirable), by means of the OS32 PC software
 Change of parameters during operation
 Readout of actual counter or other values by PLC or PC
The figure below explains how to connect the SD340 unit and a PC using the standard Sub-D-9
serial connector, and how to connect the RS485 terminals to a PLC.
Details about serial communication are shown in chapter 9.

Where both, RS232 and RS485 interface are in use, you can communicate by the one or

3.7. Fast Analogue Output (SA models only)
An analogue output is available with all SA models, providing a voltage output of +/- 10 volts
(Load = 2 mA), and a current output of 0 – 20 mA or 4 – 20 mA (load = 0 – 270 Ohms). All output
characteristics like beginning of conversion range, output swing etc. are freely programmable
via menu. The response time of the analogue output depends on the mode of measuring and
the sampling times used. The analogue resolution is 14 bits.
Please note that extensive serial communication with the unit may temporary increase the
analogue response time.
SD34002g_e.doc / Sep-13
Page 10 / 60
4. Operating Modes of the Counter
For best survey, all parameters of the unit are arranged in 13 expedient groups, named
“F01” - “F13”. Depending on the application, only a few of these groups may be important,
while all other groups may be irrelevant for your specific application.
All details about configuration and function of the parameters can be founds in chapter 6.
Practical examples for settings are shown in chapter 7.
This section describes possible applications and operating modes of the unit.
The operation mode can be set under parameter group F02, parameter # F02.004.

It is possible to cycle the display between all reading modes shown in the following
function tables, by pressing one of the front keys or by using one of the control inputs
(you must have assigned the "display scrolling function" to one of the keys or the
inputs under menu F05 to activate the scrolling of the display).

LED L1 (red) and L2 (yellow) indicate which of the values is actually visible in display
L1 on: the speed of encoder 1 is displayed
L2 on: the speed of encoder 2 is displayed
L1 and L2 on: the combined value [encoder1]*[encoder2] is displayed.

LEDs shining continuously indicate: actual measuring value.
LEDs blinking slowly indicate: minimum value
(since last reset of the min/max memory).
LEDs blinking fast indicate: maximum value (since last reset of the min/max memory).

Scrolling of the display from one reading mode to another will not affect the function
of the preselection outputs K1 – K4

The analogue output (models SA) can be assigned to any of the readings accessible in
the display, by a special parameter. Scrolling of the display from one reading mode to
another will not affect the analogue output.

With all operating modes the evaluation of the input frequencies occurs fully
separately with use of individual scaling factors. Please observe that only integer
results after the scaling operations, but no decimal positions will appear in the
display. Where you like to display your result with decimals, please scale your value
correspondingly higher (by factor 10, 100 or 1000) and then use a decimal point to
receive the desired display value (see examples under 7.1)

With all encoders providing information about the direction of rotation
(e.g. quadrature encoders A/B/90°), the unit will also display a sign (positive with
A leading B and negative with B leading A). Preselection values can be set for
response to absolute values only (no consideration of the actual sign), or for response
to the signed value. With models SA the analogue output will also change the
+/- polarity in accordance with the actual sign.

All combinations [encoder1] * [encoder2] are calculated straightaway according to the
individual operating mode and the scaling factor of each channel. Please take care
that the results to combine are scaled with proper and compatible dimensions
(don't compare apples and oranges)

Your choice of operating mode will decide how in general the two encoder frequencies have to
be treated. It will not affect the scaling or the measuring characteristics or the final
presentation of the result.

consideration of the individual scaling of each channel. The final result can once more be
scaled into user-friendly engineering units by means of the special scaling parameters in
parameter group F02.
Besides the actual speeds and the sum value, the unit also records minimum and maximum
values of the sum.
Preset K1 is related to the absolute speed of encoder 1.
Preset K2 is related to the absolute speed of encoder 2.

difference, with consideration of the individual scaling of each channel. The final result can
once more be scaled into user-friendly engineering units by means of the special scaling
parameters in parameter group F02.

4.5. Product of Two Speeds (encoder 1 x encoder 2): F02.004 = 4
Both inputs, encoder 1 and encoder 2, are active. Both speeds are multiplied to form the
product, with consideration of the individual scaling of each channel. The final result can once
more be scaled into user-friendly engineering units by means of the special scaling parameters
in parameter group F02.

4.6. Ratio of two Speeds: F02.004 = 5 or 6
Both inputs, encoder 1 and encoder 2, are active. The unit calculates the ratio of the two
speeds, with consideration of the individual scaling of each channel. The final result can once
more be scaled into user-friendly engineering units by means of the special scaling parameters
in parameter group F02 (conversion factor K = F02.09 : F02.08), see figure below*).
F02.004 = 5 calculates [encoder1] : [encoder2]
F02.004 = 6 calculates [encoder2] : [encoder1]

*) The unit presents the ratio of the two speeds as an integer number only, e.g. if both speeds are equal,
the unit would just display "1". To display a ratio with decimal positions like 1.0 or 1.00 or 1.000 etc. it
is necessary to follow one of these hints:
a. scale the speed used as numerator by a factor of 10 or 100 or 1000 higher than the denominator, or
b. set parameters F02.009 (multiplier) and F02.008 (divider) with a ratio of 10, 100 or 1000

4.7. Percentaged Speed Difference: F02.004 = 7 or 8
Both encoder inputs "encoder1" and "encoder2" are active. With consideration of the individual
scaling of each channel the unit calculates the percentaged difference as shown below:
F02.004 = 7:
Display =
[ speed of encoder 1 ]
-
[ speed of encoder 2 ]
x 100%
[ speed of encoder 2 ]
F02.004 = 8:
Display =
[ speed of encoder 2 ]
-
[ speed of encoder 1 ]
x 100%
[ speed of encoder 1 ]
Parameter „Percent Format“ (F02.018) determines the number of decimal positions of the result:
0 = display range -999999 to + 9999999 %
1 = display range -99999,9 to +99999,9 %
2 = display range -9999,99 to +9999,99 %
3 = display range -999,999 to +999,999 %
The final percentage result can once more be scaled into user-friendly engineering units by
means of the special scaling parameters in parameter group F02
Besides the actual speeds and the ratio the unit also records minimum and maximum values of
the ratio.
Preset K1 is related to the absolute speed of encoder 1.
Preset K2 is related to the absolute speed of encoder 2.

5. Keypad Operation
An overview of all parameters and explanations can be found under section 6.
The menu of the unit uses four keys, hereinafter named as follows:
PROG



UP
DOWN
ENTER
Key functions depend on the actual operating state of the unit. Essentially we have to describe
three basic states:
 Normal operation
 General setup procedure
 Direct fast access to presets and set values
5.1. Normal Operation
In this mode the unit operates as a counter according to the settings defined upon setup. All
front keys may have customer-defined functions according to the specifications met in the
keypad definition menu F05 (e.g. scrolling of the display, Reset, Inhibit etc.)
5.2. General Setup Procedure
The unit changes over from normal operation to setup level when keeping the P key down
for at least 2 seconds. Thereafter you can select one of the parameter groups F01 to F13.
Inside the group you can now select the desired parameter and set the value according to need.
After this you can either set more parameters or return to the normal operation.
The adjoining sequence of key operations explains how to change
Parameter number 060 of group F06 from the original value of 0 to 8

disabled. New parameter settings become active after return to
normal operation only.
5.3. Direct Fast Access to Presets
To get to the fast access routine, please press both
and

at the same time
This will access the parameter group F01 right away. To change of the settings follow the same
procedure as already described above. Besides the advantage of direct access, the fundamental
difference to general setup is the following:
During the fast access procedure all counter functions remain fully active.
Access is limited to presets; no other parameters can be changed.
SD34002g_e.doc / Sep-13
Page 21 / 60
5.4. Change of Parameter Values on the Numeric Level
The numeric range of the parameters is up to 6 digits. Some of the parameters may also include
a sign. For fast and easy setting or these values the menu uses an algorithm as shown
subsequently. During this operation the front keys have the following functions:
PROG
Saves the actual value
shown in the display and
returns to the parameter
selection level



UP
Increments the
highlighted
(blinking) digit
DOWN
Decrements the
highlighted
(blinking) digit
ENTER
Shifts the cursor (blinking
digit) one position to the
left, or from utmost left
to right
With signed parameters the left digit scrolls from 0 to 9 and then shows “–„ (negative) and
“-1“ (minus one). The example below shows how to change a parameter from the setting 1024
to the new setting 250 000.
This example assumes that you have already selected the parameter group and the parameter
number, and that you actually read the parameter value in the display.
Highlighted digits appear on colored background.

5.5. Code Protection against Unauthorized Keypad Access
Parameter group F07 allows to define an own locking code for each of the parameter menus.
This permits to limit access to certain parameter groups to specific persons only.
When accessing a protected parameter group, the display will first show “CODE” and wait for
your entry. To continue keypad operations you must now enter the code which you have stored
before, otherwise the unit will return to normal operation again.
After entering your code, press the ENTER key and keep it down until the unit responds.
When your code was correct, the response will be “YES” and the menu will work normally.
With incorrect code the response will be “NO” and the menu remains locked.
In order to avoid inadvertent misadjustment upon commissioning, parameter
groups F07 (keypad protection), F08 (special functions) and F11 (Linearization) are
already protected by factory setting. For access please use code 6078
5.6. Return from the Programming Levels and Time-Out Function
At any time the PROG key sets the menu one level up and finally returns to normal operation.
The same step occurs automatically via the time-out function, when during a period of 10
seconds no key has been touched.
Termination of the menu by automatic time-out will not store new settings, unless they have
already been stored by the PROG key after editing.
5.7. Reset all Parameters to Factory Default Values
Upon special need it may be desirable to set all parameters back to their original factory
settings (e.g. because you have forgotten your access code, or by too many change of settings
you have achieved a complex parameter state). Default values are indicated in the parameter
tables shown later.
To reset the unit to default, please take the following steps:

Switch power off

Press

Switch power on while you keep down both keys

and

simultaneously
Where you decide to take this action, please note that all parameters and
settings will be lost, and that you will need to run a new setup procedure
again.

6. Menu Structure and Description of Parameters
All parameters are arranged in a reasonable order of functional groups (F01 to F13). Essential
settings appear right at the beginning and optional parameters are located towards the end of
the parameter list. You must only set those parameters which are really relevant for your
specific application. Unused parameters can remain like set by default.

*) Important Hints:
a. With irregular and out-of-round motion-sequence it may be advantageous to use a
fixed number of input pulses for sampling, instead of a sampling time. This method
is suitable to stabilize or suppress undulation of the display (e.g. with unbalanced
and eccentric movements) because an overall average of one undulation is formed
b. It is advisable to always use the synchronized mode whenever measuring speed
ratios or percentaged speed difference. Otherwise unacceptable variation of the
display may occur, caused by the different timing of the two speed values
With the synchronization set to ON, parameters "Sampling Time1" (or "Sampling
Pulses") as well as "Wait Time1" are used conjointly for both encoders and the
corresponding settings for encoder 2 are inoperative. The response time of the unit
depends in each case on the lower one of the two input frequencies
c. Where the low-pass filter is used to limit the input frequency, higher frequencies
than indicated will no more be evaluated correctly

Set Value1: Preset value to simulate fixed input frequency
When you have assigned the function "Set Frequency 1" to any of
the front keys or the control inputs (see parameter group F05),
then this function can be used to temporary substitute the real
input frequency of encoder 1 by a virtual frequency according to
setting. This e.g. allows simulation of the unit and all functions /
outputs while the machine itself is in standstill. When the Set
Value1 is set to 2000 the frequency value corresponds to 20.00
Hz.
*)
Practical setting examples for these display modes can be found in chapter 7.
**)
For setup and scaling of the unit please always use decimal format first and
set your display to full seconds. When you find that all other functions work fine, then
change over to the desired clock format.

Start-up Mode1: Start-up delay for the switching outputs *)
The start-up delay is suitable to temporary suppress the control function
of a switching output (in general for monitoring of a minimum value).
The machine then is allowed to start up first, prior to activation of the
alarm. The start-up delay becomes active upon power-up of the unit or
after the unit has detected "standstill".
The following settings are available (always for encoder 1):
0 = Start-up delay OFF
1 = timed delay: 001 second
2 = timed delay: 002 seconds
3 = timed delay: 004 seconds
4 = timed delay: 008 seconds
5 = timed delay: 016 seconds
6 = timed delay: 032 seconds
7 = timed delay: 064 seconds
8 = timed delay: 128 seconds
9 = automatic delay until first exceeding of the minimum value
10 = external suppression by means of a control input
Standstill Time1: Time for definition of "standstill" of encoder 1
After the unit has detected "frequency = 0" (see parameter "Wait
Time1"), the unit will continue waiting until "Standstill Time1" has
elapsed and then finally report "standstill of encoder 1".


x-registers are to set the numeric value that the unit would display without
linearization

y-registers are to set the numeric value that should be displayed instead,
i.e. the (y3) setting will replace the (x3) display value

between the interpolation points the unit automatically uses linear
interpolation

x- registers have to use continuously increasing values, e.g. the lowest display
value must be set to register x0, and the highest display value must be set to
x16

Independent of the selected linearization mode, the possible setting range of
all registers x0, y0, … x16, y16 is always -199999 … 999999.

For measuring values outside of the defined linearization range, please note:
If the measuring value is lower than (x0), the linearization result will always
be (y0).
If the measuring value is higher than (x15), the linearization result will always
be (y15).

7. Practical Examples for Setup and Scaling
For proper scaling of the unit is mandatory to respond to the following questions:
 Which input frequency (Hz) will the encoders produce at a typical speed?
 Which numeric value do we intend to display at this typical speed?
(sequence of numbers including the decimal positions)
 Is the display characteristics proportional (speed) or reciprocal (time)?
The subsequent settings refer to the illustrations shown in chapter 4.
7.1. Settings for the Example a) of Chapter 4.1 (Speed Display)
Machine specifications:
Encoder:
TTL A, /A, B, /B
4096 ppr.
Measuring wheel:
Circumference = 500
mm
(diameter = 159,2 mm)
Expected Line speed:
0 ... 300 meters/min
Desired display value:
0 ... 300,0 m/min
(one decimal position)
Calculations:
With a speed of 300 m/min
the measuring wheel will
rotate at 600 rpm.
With a 4096 ppr encoder
we will get 600 x 4096 =
2 457 600 Imp./ min equal
to 40 960 Imp /sec. (Hz)
This means at maximum
speed of 300 m/min the
encoder frequency is
40 960 Hz.
Relevant parameters:
F02.004 0
F02.0005 1
F03.022 0
F03.024 0,100 (assumed)
i.e. display cycle = 0.1 sec.
F03.025 0,10 (display zero with f < 10 Hz)
F03.027 40960
F03.028 3000
(= 300.0 with a decimal point)
F03.029 0
We expect a display value
of 3000 (to display 300.0)
7.2. Settings for the Example b) of Chapter 4.1 (Baking Time)
Machine specifications:
Proximity switch:
Standard PNP 3-wire
type
Sensed pinion:
16 teeth
70 rev. of the pinion =
1 meter of travelling
distance
Furnace length: 60 m
Range of baking times:
from 10 min. up to 2 h
Desired display format:
01h : 59min : 59sec
SD34002g_e.doc / Sep-13
Calculations:
To run over the full furnace
distance of 60 meters, the
proximity will generate a
total number of impulses of
60 x 70 x 16 imp.
= 67200 impulses totally
With maximum speed we
expect a transition time of
10 min. equal to 600 sec.
With 67200 impulses in
600 seconds our frequency
corresponds to 112 Hz
Relevant parameters:
F02.004 0
F02.005 0 (with clock display format
decimal points appear
automatically)
F03.022 5
F03.024 1,000 (assumed)
i.e. display cycle = 1 sec
F03.025 1,00
(frequencies < 1 Hz = standstill)
F03.027 112
F03.028 600
F03.029 Use setting "1" first and verify
correct display of seconds. Then
change over to "3" (clock format)
Page 44 / 60
7.3. Settings for Example "Differential Speed" of Chapter 4.4
Machine specifications:
Both encoders:
1024 ppr quadrature
A / B / HTL 24 V
Circumferences (rolls):
all rolls should have the
same circumference of
350 mm
Speeds:
Maximum speed on
both conveyors is
200 m/min
Desired display:
Differential speed with
two decimal positions
(format +/-99.99 m/min)
Calculations:
Wit a maximum speed of
200 m/min and a roll
circumference of 0.350 m
we will get a roll rpm of
200 m/min : 0,350 m
= 571.43 rpm
This results in encoder
frequencies of
571.43 x 1024 Imp/min
= 585 143 Imp./min
= 9752.4 Imp./sec. (Hz)
Relevant parameters:
F02.004 3
F02.005 all = 2
F02.006
F02.007
F02.008 both = 1000
F02.009 (no re-scaling necessary)
F02.016 1
It is advisable to synchronize
both measuring channels
whenever we use combined
display results
F03.022 both = 1
F04.034
F03.023 For correct calculation of the
F04.035 difference we must ensure that
both speeds have the same
direction (both positive or both
negative), i.e. either
[+Geber1] - [+Geber2] or
[-Geber1] - [-Geber2]
F03.024 both = 0.500 (assumed), i.e.
F04.036 display cycle = 0,5 sec.
F03.025 both = 0,20 (assumed), i.e.
F04.037 speed = 0 with f < 5 Hz
F03.027 both = 9752 *)
F04.039
F03.028 both = 20 000 *)
F04.040 (will appear as 200.00 since we
desire to have two decimal
positions)
F03.029 both = 0
F04.041
*) With high accuracy demand we are free to increase the frequency setting tenfold. This will allow to
also consider the remaining decimal position of our calculation (i.e. F03.027 = 97524).
In order to maintain the proportionality we have then to increase also the desired display value by
factor 10 (i.e. F03.028 = 200 000).

7.4. Example for Use of the Filter
The subsequent illustrations explain the mode of action of the Filter with different settings. For
this explanation we assume:
 Sampling-Time = 10 msec
 The input frequency jumps temporary up to a higher value, and after a time of 60 msec it
jumps back to the original value again
 We use in sequence the filter settings 0, 1, 3 and 5
Hz
a) Jump of input frequency
b) Filter = 1
c) Filter = 3

d) Filter = 5

Sampling Time = 10 msec
Time constant T = 20 msec. (with filter setting = 5)
a)
Jump: this shows how the unit would respond with the filter switched off
b)
With Filter set to "1" the unit forms a floating average value over the last two measuring
cycles. As a result, after the first sampling period we can only see 50% of the jump and
only one cycle later we can see 100%.
c)
With Filter set to "3" the unit forms a floating average value over the last eight measuring
cycles. As a result, after the first sampling period we can only see 12.5% (1/8) of the jump
and only 7 cycles later we would come up to 100%. However, since the whole jump
duration is only 6 cycles long, the display already starts to step back to the previous value
before we reached the full jumping level
d)
With Filter set to "5" the unit uses an exponential curve to smoothen the jump. Since the
Time Constant of the exponential filter always equals 2 sampling times, we reach 63% of
the jumping level after 20 msec.

8. Appendix for models SD/SA/SR 6xx
8.1. Relay Outputs
All available models are shown in section 1. While models SD 3xx provide high-speed
transistor outputs only, all models SD 6xx provide four additional relay outputs, operating in
parallel to the high-speed transistor outputs K1 – K4.
All electrical connections of 6xx models are fully similar to the 3xx models, except that with 6xx
models the back plane is equipped with an additional 12-position terminal strip.

8.2. Front Thumbwheel Switches
Moreover, the models shown below provide thumbwheel switches on the front panel, for
simple and easy setting of preselection levels. Every row allows in maximum 9 decades and
one blank field for separation. The customer is free to specify any desired combination and
number of decades individually, which is not wider than totally 10 spaces.
As an example, with model 642 it is possible to specify
“Set1 = 3 decades, Set2 = 6 decades”, or e.g. “Set1 = 8 decades” etc.
Where your order does not clearly state a different array of the thumbwheels, the
units will be supplied with 2 x 4 decades respectively 4 x 4 decades
Models 642 can have
max. 2 switch sets on front
Thumbwheel set 1

Thumbwheel set 2
Models 644 can have
max. 4 switch sets on front
Thumbwheel set 1

Page 47 / 60
8.3. Specific Parameters for Units with Thumbwheel Switches
The following parameter settings apply for units with thumbwheel switches only and are not
relevant for all other models:
8.3.1. Read and update thumbwheel switch settings
All actual thumbwheel settings are automatically considered when the unit is powered up.
However, changes during normal operation will not be considered, unless upon special remote
command. This can either be the actuation of one of the front keys, or a command signal to one
of the control inputs.
Please see section 6.2.4 with the parameter group F05.
It is a “must” to assign the function "16" to at least one of the front keys or one of the
control inputs. These functions will read the settings of the front switches. Otherwise there
will be no way to activate changes of the switch settings during operation.
8.3.2. Positive or negative sign of thumbwheel settings
In general and as a default, the front thumbwheel settings are assumed to have a positive sign.
Some applications may however require that one or the other setting should be interpreted as a
negative value.
Parameter F06.071 allows assigning negative signs to any of the front thumbwheels, following
a binary schema as shown in the table below:
Setting of F06.071
Sign of Thumbwheel 1
Sign of Thumbwheel 2
Sign of Thumbwheel 3
Sign of Thumbwheel 4
00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15
+ - + - + - + - + - + - + - + + + - - + + - - + + - - + + - + + + + - - - - + + + + - - - + + + + + + + + - - - - - - - -
8.3.3. Assignments between thumbwheels and switching outputs
In general and as a default, thumbwheel switch set No.1 refers to output K1; thumbwheel
switch set No.2 refers to output K2 etc. This may be convenient for most of the applications,
but also cause inconvenience with some operating modes of the counter.
As an example, when using the “Sum Mode” (see section 4.3), the outputs K1 and K2 are firmly
attached to the encoder1 counter and outputs K3 and K4 are firmly attached to the sum of
encoder1 and encoder2.
SD34002g_e.doc / Sep-13
Page 48 / 60
From this follows that, if you use a counter model with two sets of thumbwheels only
(thumbwheel set 1 and thumbwheel set 2), you would only have preselections referring to
encoder1, but no thumbwheel access to the sum.
To avoid such kind of limitations, parameter F06.072 allows free assignments between any of
the thumbwheel switch sets (switch1 to switch4, see previous figure) and any of the four
outputs (K1 to K4)

9. Appendix: Serial Communication Details
Serial communication with the counter can be used for the following purposes:
 PC setup of the counter, using the OS32 Operator software
 Automatic and cyclic transmission of counter data to remote devices like PC, PLC or
Data Logger
 Communication via PC or PLC, using the communication protocol
This section describes the essential and basic communication features only. Full details are
available from the special SERPRO manual.
9.1. Setup of the Counter by PC
Connect the counter to your PC as shown in section 3.6 of this manual. Start the OS32 Operator
software. After a short initializing time you will see the following screen:
If your screen remains empty and the headline of your PC says „OFFLINE“, select „Comms“ of
the menu bar and check your serial communication settings.
The edit field on the left shows all actual parameters and provides full editing function. The
„File“ menu allows to store complete sets of parameters for printout or for download to a
counter.
When editing parameters, please use the ENTER key of your PC after each entry, to ensure
storage of your data to the counter.
SD34002g_e.doc / Sep-13
Page 50 / 60
9.2. Automatic and Cyclic Data Transmission
Set any cycle time unequal to zero to parameter F10.110.
Set the serial access code of the register you would like to transmit to parameter F10.111. In
theory you could transmit any of the internal registers by serial link, however only the following
registers make really sense:
F10.111 = 6 :
=7:
=8:
=9:
= 10 :
= 14 :
Actual speed of encoder 1
Actual speed of encoder 2
Actual analogue output voltage (SA models only)
Latest minimum value (minimum record memory)
Latest maximum value (maximum record memory)
Actual value indicated in the display
Dependent on the setting of parameter F10.109 the unit transmits one of the following data
strings, under cycle control of the timer:
(xxxx = counter data*, LF = Line Feed <hex. 0A>, CR = Carriage Return <hex 0D>)
*) Leading zeros will not be transmitted
F10.109 = 0 :
F10.109 = 1 :

9.3. Communication Protocol
When communicating with the unit via protocol, you have full read/write access to all internal
parameters, states and actual counter values. The protocol uses the DRIVECOM standard
according to DIN ISO 1745. A list with the most frequently used serial access codes can be
found in the previous section.
To request data from the counter, the following request string must be sent:
EOT
AD1 AD2 C1 C2 ENQ
EOT = Control character (Hex 04)
AD1 = Unit address, High Byte
AD2 = Unit address, Low Byte
C1 = Register code to read, High Byte
C2 = Register code to read, Low Byte
ENQ = Control character (Hex 05)
The example shows how to request for transmission of the actual encoder 1 speed
(register code :9), from a unit with unit address 11:

Page 51 / 60
Upon correct request, the counter will respond:
STX C1 C2 x x x x x x x ETX BCC
STX = Control character (Hex 02)
C1 = Register code to read, High Byte
C2 = Register code to read, Low Byte
xxxxx = Counter data *)
ETX = Control character (Hex 03)
BCC = Block check character
*) Leading zeros will not be transmitted
The Block-Check-Character represents the EXCLUSIVE-OR function of all characters from
C1 to ETX (both comprised).
To write to a parameter, you have to send the following string:
EOT AD1 AD2 STX C1 C2 x x x x x x x ETX BCC
EOT = Control character (Hex 04)
AD1 = Unit address, High Byte
AD2 = Unit address, Low Byte
STX = Control character (Hex 02)
C1 = Register code to write, High Byte
C2 = Register code to write, Low Byte
xxxxx = Value of the parameter
ETX = Control character (Hex 03)
BCC = Block check character
Upon correct receipt the unit will respond by ACK, otherwise by NAK.
Every new parameter sent will first go to a buffer memory, without affecting the actual
measuring process. This function enables the user, during normal measuring operation, to
prepare a complete new parameter set in the background.
To activate transmitted parameters, you must write the numeric value “1” to the “
Activate Data“ register. This immediately activates all changed settings at the same time.
Where you like the new parameters to remain valid also after the next power up of the unit,
you still have to write the numeric value “1” to the „Store EEProm“ register. This will store all
new data to the EEProm of the unit. Otherwise, after power down the unit would return with
the previous parameter set.
