3. Introduction
The BY340 / BY641 units are suitable to operate as electronic synchronous controllers with
speed-variable drives of any kind and any size, provided they dispose of an analog input to set
the speed. The operation is based on a Master / Slave principle.
The Master could basically be any moving part of a machine, provided there is a quadrature
incremental encoder signal available from the Master motion. The Slave would typically be a
speed-variable drive like an Inverter Drive or Servo Drive or DC Drive, but could also be a
hydraulic system with a servo valve or similar. In any case a quadrature feedback signal is also
necessary from the Slave.
The subsequent drawing shows an example of speed synchronization between two belts,
including automatic position adjustment by means of index sensors (optional).

By340_04b_oi_e.doc / Apr-16 Page 10 / 42
4.1. Power Supply
The BY340 synchronizer accepts both, a 17 …40 VDC power or a 24 VAC power for supply via
terminals 17 and 1. The current consumption depends on the level of the input voltage and
some internal conditions; therefore it can vary in a range from 100 …200 mA
(auxiliary currents taken from the unit for encoder supply not included).
4.2. Auxiliary Outputs for Encoder Supply
Terminals 2 and 18 provide an auxiliary output with approx. +5.2 VDC (300 mA totally).
Terminals 3 and 19 provide an auxiliary output with approx. +24 VDC (240 mA totally)
4.3. Impulse Inputs for Incremental Encoders
All input characteristics of the impulse inputs can be set by the parameter menu, for each of
the encoders separately. The unit works with quadrature information (A / B, 90°) only. In theory,
any of the following encoder characteristics would be applicable:
Symmetric differential signals according to RS422 standard, however
1 V min. as differential voltage.
TTL inputs at a level of 3.0 to 5 V (differential, with inverted signal)
TTL inputs at a level of 3.0 to 5 V (single-ended) *)
HTL signals at a 10 … 30 V level
(alternatively differential A, /A, B, /B, or single-ended A, B only)
Pulses from photocells or proximity switches etc. providing a HTL level (10 …30 V)
Proximity switches according to NAMUR (2-wire) standard
(may need additional remote resistor)
*) requires special settings of the threshold parameters, see 8.2.9 “Special parameters F08”
For trouble-free angular synchronization it is mandatory to use quadrature
encoders with channels A and B or with channels A, /A, and B, /B (90° phase
displacement).
Where the impulse level is HTL (10 … 30 V) you can use either single-ended
signals (A and B only) or differential signals (A, /A, B, /B).
Where the impulse level is TTL or RS422, it is strictly recommended to use
symmetric differential signals (with inverted channels /A and /B). Under
industrial environment conditions, single-ended TTL signals may cause
serious problems due to insufficient EMC immunity of the signal lines.
All encoder input lines are internally terminated by pull-down resistors (8.5
kΩ). Where encoders with pure NPN outputs are used, corresponding pull-up
resistors must be available inside the encoder or externally to ensure proper
function (1 kΩ... 3.3 kΩ).

By340_04b_oi_e.doc / Apr-16 Page 11 / 42
4.4. Control Inputs Cont.1 –Cont.4
These inputs can be configured for remote functions like Reset, Phase trimming, Index
evaluation or display selection purpose. All control inputs require HTL level. They can be
individually set to either NPN (switch to -) or PNP (switch to +) characteristics. For applications
where edge-triggered action is needed, the menu allows to set the active edge (rising or
falling). The Control inputs will also accept signals with Namur (2-wire) standard.
For reliable operation of the Control Inputs a minimum impulse duration of 50 µs.
must be ensured. Especially when using the Z marker pulse of a HTL encoder for
index tracking, please verify that this minimum duration can be kept even with
maximum speed of the machine.
4.5. Switching Outputs K1 –K4
BY340 provides four digital outputs to signal control states like “out of synchronization” or
“Index o.k.”. 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).
4.6. Serial Interface
The serial RS232 interface can be used for the following purposes:
Set-up of the unit by PC with use of the OS32 PC software
Remote change of parameters during operation
Remote readout of actual values by PLC or PC

For details of the serial communication protocol, please refer to the special SERPRO manual.
4.7. Analog Output
The unit provides a voltage output of +/- 10 volts (load = 3 mA) or a current output of
0 …20 mA (load = 0 …270 Ohms), both at a resolution of 14 bits (13 bits + sign). With most
standard applications the voltage output is used as a speed reference signal, connected to the
speed input of the Slave drive.
Important note: “voltage out” and “current out” must not be used together.
Please do never connect mA and V simultaneously!
Continuous serial communication may temporary increase response times.

By340_04b_oi_e.doc / Apr-16 Page 12 / 42
5. Principle of Operation
5.1. Synchronization
The Synchro controller receives full positional information about the master axis by means of
the Master encoder. This incremental information can be scaled by means of the
Master Scaling Factor (subsequently named Factor1). From this information the unit can
calculate an analog speed output signal which is necessary to make the Slave axis exactly
follow to the Master.
The feedback of the actual position of the Slave axis is given by the Slave encoder. This
information uses a separate impulse scaling by means of the Slave Scaling Factor
(subsequently named Factor2).
Master position and Slave position are compared continuously, and the analog output is
updated correspondingly within very short cycle times of only about 100 µs. As a result, both
positions can be kept inside an error window of typically +/- 5 encoder increments (e.g. the
Slave may lead or lag the Master by a few encoder increments, but will never loose position)
It is easy to understand, that this kind of positional and angular synchronization includes at the
same time error-free speed synchronization of Master and Slave.
When we move the Master forward or reverse by a distance “dMaster”, at the same time the
Slave will move forward or reverse by a distance “dSlave”, under consideration of the impulse
scaling factors Factor1 and Factor2. In general Factor1 is the parameter to change the speed
ratio, and Factor2 is considered as a machine constant.
With most of the applications it is desirable to have proportional characteristics of Factor1, i.e.
we like to increase the Slave speed when we increase Factor1.
Some application however may require reciprocal characteristics (e.g. when we use the unit for
a rotary cutter application where Factor1 is used to set the cutting length. In this case, higher
setting requires lower Slave speed, i.e. Factor1 has to operate reciprocally.
Both, proportional and reciprocal characteristics can be selected by parameter. Depending on
these settings, the distances (and also the speeds) follow to one of the formulae below:
Proportional Operation:
Reciprocal Operation:

By340_04b_oi_e.doc / Apr-16 Page 13 / 42
5.2. Mechanical Phase and Position Considerations
Normally the synchronizer would always keep the angular phase or relative position between
Master and Slave, which has existed while the unit has been powered up, or which has been
defined manually while the unit was kept in the Reset state.
However it may be desirable to adjust the relative position in standstill or on the fly, by means
of manual or remote commands, or even to set a certain position automatically, triggered by
external events. For this reason, phase trimming functions and index functions have been
designed, which can be assigned to either the front keys or the control inputs. Once the desired
phase adjust commands have been assigned, the final function can be specified by setting of
the appropriate Operating Mode of the unit (see chapter 6)
5.2.1. Phase Trimming under Timer Control (Modes 1 –4 and 7 –8)
Activating one of the +/-Trim commands allows to temporary run the Slave at a speed which is
slightly higher (Trim+) or slightly lower (Trim-) than the correct synchronous speed, which
results in a displacement of phase between Master and Slave (Slave leads or lags the Master).
The differential speed to displace the phase is parameter adjustable. The system returns to
closed-loop synchronous operation in a new relative position, as soon as the Trim command is
released again.
5.2.2. Phase Trimming under Impulse Stepper Control (Modes 5 and 6)
With this mode of operation the +/-Trim commands must be assigned to two of the Control
Inputs, which then operate as impulse inputs from a remote source (push button or PLC or else).
Every impulse applied to the Trim+ input will advance the Slave by one differential increment*)
and every impulse applied to the Trim- input will retard the Slave with respect to the Master.
This method allows adjusting the relative position step by step
5.2.3. Lead or Lag by a programmable distance (Mode 3)
With this mode, every impulse detected on the Index Master or Index Slave input will jump the
Slave forward or reverse by a fixed distance, as set to the Offset register. This method of phase
displacement allows toggling the relative phase between two or more scheduled operating
positions (e.g. 0°, 90°, 180° and back to 0°).
5.2.4. Position Definition by Index Inputs (Modes 2, 6 and 8)
Index signals may be used do define and to automatically adjust mechanical positions or events
between the drives (for an example see the figure under section 3). Index signals can be
generated by proximity switches, photo cells or by use of the marker pulse of a HTL encoder.
Where you intend to use marker pulses from TTL encoders, you have to translate the Z and /Z
information to HTL level before applying it to the controller.
While modes 2 and 6 are designed for immediate and tough correction of index errors, mode 8
provides a soft way of making corrections. The Trim register is used to approach a new position
by means of an adjustable differential speed.
*) Mechanically, one differential increment equals to one Slave encoder increment divided by Factor2

By340_04b_oi_e.doc / Apr-16 Page 14 / 42
Please observe the minimum duration of 50 µs. for index pulses
Every index pulse must clearly mark one explicit and repeatable event
within one machine cycle

Direct fast access to scaling factors
7.1. Normal Operation
In this mode the unit operates as a synchronous controller 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 F06 (e.g. Reset or Trim or else)
7.2. General Setup Procedure
The unit changes over from normal operation to setup level when keeping the key down
for at least 2 seconds. Thereafter you can select one of the parameter groups F01 to F09.
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.
See example on the next page…

Normal operation
During the general setup procedure all control activities remain disabled.
New parameter settings become active after return to normal operation only.
7.3. Direct Fast Access to Speed Ratio Setting
To get to the fast access routine, please press both
and

at the same time
This will access the parameter group F01 right away. To change the 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 control functions remain fully active.
Access is limited to Factor settings; no other parameters can be changed.

7.4. 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

ENTER
Saves the actual
value shown in the
display and returns

selection level
Increments the
highlighted
(blinking) digit
Decrements the
highlighted
(blinking) digit
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 actual setting
of 1024 to the new setting of 250 000.
This example assumes that you have already selected the parameter group and the parameter
number, and that you actually read the parameter value in the display.
Highlighted digits appear on colored background.

7.5. Code Protection against Unauthorized Keypad Access
Parameter group F09 allows to define an own locking code for each of the parameter menus.
This permits to limit access to certain parameter groups to specific persons only.
When accessing a protected parameter group, the display will first show “CODE” and wait for
your entry. To continue keypad operations you must now enter the code which you have stored
before, otherwise the unit will return to normal operation again.
After entering your code, press the ENTER key and keep it down until the unit responds.
When your code was correct, the response will be “YES” and the menu will work normally.
With incorrect code the response will be “NO” and the menu remains locked.
7.6. 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.
7.7. Reset all Parameters to Factory Default Values
Upon special need it may be desirable to set all parameters back to their original factory
settings (e.g. because you have forgotten your access code, or by too many change of settings
you have achieved a complex parameter state). Default values are indicated in the parameter
tables shown later.
To reset the unit to default, please take the following steps:

Switch power off

Press

and

simultaneously

Switch power on while you keep down both keys
Where you decide to take this action, please note that all parameters and
settings will be lost, and that you will need to run a new setup procedure again.

8. Menu Structure and Description of Parameters
All parameters are arranged in a reasonable order of functional groups (F01 to F09)
You must only set those parameters which are really relevant for your specific application.
Unused parameters can remain as they actually are.
