(Software APFIFF11 V1.13 or higher)
Select the Shaft Synchronization Application in menu M6 on page
S6.2.
1. INTRODUCTION
The Shaft Synchronization Application provides Position synchronization control of a follower drive
to a master position signal, with the ability to control the synchronization ratio online via fieldbus,
parameter or by digital trim +/- input. The drive requires feedback from an encoder or resolver. The
master position signal comes from an incremental encoder or a single phase pulse generator and is
read using the OPT-A7 board if the follower drive employs an induction motor or the OPT-BC board
if the motor is of a PM synchronous type.
The application offers general purpose functionality support also for independent speed or torque
control when the shaft synchronization mode is not enabled.
Specific application features:
• Synchronization commands: enable sync. mode, engage/release, freeze and reference
speed are all controlled from digital inputs or fieldbus control register
• Ratio range -4 to +4 in steps of 1/65536 can be controlled by parameter or fieldbus in RUN
mode
• Programmable trim inputs +/- and trim ratio change parameter for temporary ratio change
from digital inputs
• Programmable ratio change ramp
• Programmable engage/ release ramp
• Digital or relay outputs for “Ratio change” and “Synchronization engaged”
• Supported fieldbuses: Profibus, CanOpen, Modbus, Modbus TCP
• Synchronization regulator cycle time is 5 ms
• Phasing from standstill or during running (offset of follower position)
• Mechanical brake control
Other general purpose features:
• Induction motor identification
• PM motor rotor angle identification
• All digital and analogue inputs and outputs are freely programmable
• Analogue input signal range selection, with automatic adjustment
• Supervision of two frequency thresholds
• Supervision of torque limit
• Supervision of reference limit
• Second ramp and S-shape ramp programming
• Programmable start/stop and reverse logic
• DC-braking at start and stop
• Programmable U/f curve and switching frequency
• Fully programmable motor thermal and stall protection
• Input and output phase supervision
• Joystick with programmable hysteresis
NOTE: The Shaft Synchronization application creates a rigid electrical coupling between master and
follower(s) axis. The application is not suitable if there is a rigid mechanical coupling
between master and follower(s).

1.1 Requirements
− NXP frequency converter with control board type VB00561 (“nxp2” type) or newer.
− NXP00002V155 system software package (NXP00002V160 for the support of single phase master
pulse reference).
− Double encoder board OPTA7 for induction motor with HTL incremental encoder for closed loop
control. The second encoder channel is used for master pulse reference.
− Resolver board OPTBC for permanent synchronous motor with resolver feedback for closed loop
control. The second encoder channel is used for master pulse reference.
− Application license key is needed for shaft synchronization functions (based on power unit serial
number)
However there is a 2 week trial time without charge. It is always possible to run the drive in
multi-purpose mode without the license key.
1.2 Trial Time period
Trial time is very useful for test and evaluation. If FC has to be replaced during a weekend there is 2
weeks trial time for free and during that time a new license can be ordered from Vacon.
After loading the application it will be possible to run in Shaft synchronization mode without license
key for 2 weeks (336 h)
STEPS IN TRIAL PERIOD
1. A warning F72 with the text “Trial time” will appear on the display (until <24 hours left) at
every run request
rising edge in shaft synchronization mode.
2. When only 24 hours is left of trial time the warning F73 “<24 hours left” is triggered and
remains on all the time when FC is in run in shaft synchronization mode.
3. When trial time has expired and the drive will trip with F72 Error: “TrialTimeOver”
NOTE: Drive will trip in run mode!
4. A monitoring value V1.23 on the keypad shows Trial time left (h). The trial time starts from
336 h and counts down to 0.
NOTE:The trial time counter is counting when the shaft synchronization is enabled by digital input
or from fieldbus.

4. JUMPER SETTING ON THE OPT-A7 BOARD
The X5 jumper selects which channel is sent to the repeater outputs (connections17-20)
On the Master drive OPT-A7 the channel 1 (DIC) has to be sent to repeater outputs.
If there are more than one follower normally channel 2 (DID) is to be sent from follower(s) to
follower(s). Then all drives will follow master drive.
See the Option board manual UD00741 for more information.
Master drive can have any software application. Follower is regulating based on incoming encoder
channel 2 pulses.
COMMISSIONING NOTE:
Always check in option board menu (M7) that master pulses are coming to encoder channel 2
on the follower OPT-A7 board (or OPT-BC if resolver board is used).
Pulses per revolution for follower channel 2 (P7.3.1.4 Enc 2 Pulse/rev for OPT-A7) should
normally be set equals to Master encoder pulses/rev.

5. “TERMINAL TO FUNCTION” (TTF) PROGRAMMING PRINCIPLE
The programming principle of the input and output signals in the Multipurpose Control Application
as well as in the Pump and Fan Control Application (and partly in the other applications) is differ-
ent compared to the conventional method used in other Vacon NX applications.
In the conventional programming method,
Function to Terminal Programming Method (FTT), you
have a fixed input or output that you define a certain function for. This application, however, use the
Terminal to Function Programming method (TTF) in which the programming process is carried out
the other way round: Functions appear as parameters which the operator defines a certain
input/output for. See
Warning on page 11.
5.1 Defining an input/output for a certain function on keypad
Connecting a certain input or output with a certain function (parameter) is done by giving the para-
meter an appropriate value. The value is formed of the
Board slot on the Vacon NX control board
(see the product's User's Manual) and the
respective signal number , see below.
Function name
Slot Terminal number
Terminal type
Example: You want to connect the digital output function
Reference fault/warning (parameter
2.3.3.7) to the digital output DO1 on the basic board OPT-A1 (see the product's User's Manual).
First find the parameter 2.3.3.7 on the keypad. Press the
Menu button right once to enter the edit
mode. On the
value line , you will see the terminal type on the left (DigIN, DigOUT, An.IN, An.OUT)
and on the right, the present input/output the function is connected to (B.3, A.2 etc.), or if not con-
nected, a value (0.#).
When the value is blinking, hold down the
Browser button up or down to find the desired board slot
and signal number. The program will scroll the board slots starting from 0 and proceeding from A
to Eand the I/O selection from 1to 10.
Once you have set the desired value, press the
Enter button once to confirm the change.

5.2 Defining a terminal for a certain function with NCDrive programming tool
If you use the NCDrive Programming Tool for parametrizing you will have to establish the connec-
tion between the function and input/output in the same way as with the control panel. Just pick the
address code from the drop-down menu in the
Value column (see the Figure below).
Figure 1. Screenshot of NCDrive programming tool; Entering the address code
!
WARNING
Be ABSOLUTELY sure not to connect two functions to one and same
output in order to avoid function overruns and to ensure flawless
operation.
Note: The input
s
, unlike the output
s
, cannot be chan
g
ed in RUN state.

5.3 Defining unused inputs/outputs
All unused inputs and outputs must be given the board slot value 0and the value 1also for the ter-
minal number. The value 0.1 is also the default value for most of the functions. However, if you want
to use the values of a digital input signal for e.g. testing purposes only, you can set the board slot
value to 0and the terminal number to any number between 2…10 to place the input to a TRUE state.
In other words, the value 1 corresponds to 'open contact' and values 2 to 10 to 'closed contact'.
In case of analogue inputs, giving the value 1 for the terminal number corresponds to 0% signal
level, value 2corresponds to 20%, value 3to 30% and so on. Giving value 10 for the terminal number
corresponds to 100% signal level.
