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

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 differ­ent compared to the conventional method used in other Vacon NX applications.

In the conventional programming method,
have a fixed input or output that you define a certain function for. This application, however, use the

Terminal to Function Programming method (TTF)

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 para­meter an appropriate value. The value is formed of the
(see the product's User's Manual) and the

Function name

AI Ref Faul/Warn
DigOUT:B.1

Slot Terminal number
Terminal type

Example: You want to connect the digital output function

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
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 con­nected, a value (0.#).
When the value is blinking, hold down the
and signal number. The program will scroll the board slots starting from 0 and proceeding from A
to E and the I/O selection from 1 to 10.
Once you have set the desired value, press the

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 connec­tion 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).

12 • vacon "terminal to function" (ttf) programming principle

5.3 Defining unused inputs/outputs

All unused inputs and outputs must be given the board slot value 0 and the value 1 also for the ter­minal 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 0 and 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 2 corresponds to 20%, value 3 to 30% and so on. Giving value 10 for the terminal number
corresponds to 100% signal level.

7. DESCRIPTION OF PARAMETERS

On the following pages you will find the parameter descriptions arranged according to the individual
ID number of the parameter. A shaded parameter ID number (e.g.
indicates that the
page 10).
Some parameter names are followed by a number code indicating the "All in One" applications in
which the parameter is included. If no code is shown the parameter is available in all applications.
See below. The parameter numbers under which the parameter appears in different applications
are also given.

102 Maximum frequency

103 Acceleration time 1
104 Deceleration time 1

TTF programming method

Defines the frequency limits of the frequency converter.
The maximum value for these parameters is 320 Hz.
The software will automatically check the values of parameters ID105, ID106, ID315 and
ID728.

(2.1.2)

(2.1.3)

shall be applied to this parameter (see chapter 5 on

(2.1.1)

418 Motor potentiometer UP

)

These limits correspond to the time required for the output frequency to
accelerate from the zero frequency to the set maximum frequency (par. ID102).
See also parameter ID1764.

105 Preset speed 1
106 Preset speed 2

Parameter values are automatically limited between the minimum and maximum
frequencies (par. ID101, ID102).
Note the use of TTF-programming method in the Multi-purpose Control Application. See
parameters ID419, ID420 and ID421.

Linear: 0 The voltage of the motor changes linearly with the frequency in the constant

flux area from 0 Hz to the field weakening point where the nominal voltage is
supplied to the motor. Linear U/f ration should be used in constant torque
applications. This default setting should be used if there is no special
need for another setting.

Squared: 1 The voltage of the motor changes followiing a squared curve form with the

frequency in the area from 0 Hz to the field weakening point where the nomi­nal voltage is also supplied to the motor. The motor runs undermagnetised
below the field weakening point and produces less torque and electro­mechanical noise. Squared U/f ratio can be used in applications where torque
demand of the load is proportional to the square of the speed, e.g. in
centrifugal fans and pumps.

109 U/f optimisation

Automatic
torque boost

EXAMPLE:

What changes are required to start with load from 0 Hz?

The voltage to the motor changes automatically which makes the motor
produce sufficient torque to start and run at low frequencies. The voltage
increase depends on the motor type and power. Automatic torque boost
can be used in applications where starting torque due to starting friction
is high, e.g. in conveyors.

(2.5.2)

♦ First set the motor nominal values (Parameter group 2.1).

Option 1

Option 2

To get torque you need to set the zero point voltage and midpoint voltage/frequency (in
parameter group 2.6) so that the motor takes enough current at low frequencies.
First set par. ID108 to
(ID606) to get enough current at zero speed. Set then the midpoint voltage (ID605) to

1.4142*ID606 and midpoint frequency (ID604) to value ID606/100%*ID111.

: Activate the Automatic torque boost.

: Programmable U/f curve

Programmable U/f curve

NOTE! In high torque – low speed applications – it is likely that the motor will

overheat. If the motor has to run a prolonged time under these condi­tions, special attnetion must be paid to cooling the motor. Use external
cooling for the motor if the temperature tends to rise too high.

(value 2). Increase zero point voltage

(2.1.5)

Find this value Un on the rating plate of the motor. This parameter sets the voltage at the
field weakening point (ID603) to 100% * U

111 Nominal frequency of the motor

Find this value fn on the rating plate of the motor. This parameter sets the field
weakening point (ID602) to the same value.

384 AI1 joystick hysteresis

This parameter defines the joystick hysteresis between 0 and 20 %.
When the joystick or potentiometer control is turned from reverse to forward, the output
frequency falls linearly to the selected minimum frequency (joystick/potentiometer in
middle position) and stays there until the joystick/potentiometer is turned towards the
forward command. It depends on the amount of joystick hysteresis defined with this
parameter, how much the joystick/potentiometer must be turned to start the increase of
the frequency towards the selected maximum frequency.
If the value of this parameter is 0, the frequency starts to increase linearly immediately
when the joystick/potentiometer is turned towards the forward command from the
middle position. When the control is changed from forward to reverse, the frequency
follows the same pattern the other way round. See Figure 15.

(2.4.1)

The start and end of acceleration and deceleration ramps can be smoothed with these
parameters. Setting value 0 gives a linear ramp shape which causes acceleration and
deceleration to act immediately to the changes in the reference signal. Setting value

0.1…10 seconds for this parameter produces an S-shaped acceleration/deceleration.

The acceleration time is determined with parameters ID103/ID104 (ID502/ID503).

These values correspond to the time required for the output frequency to accelerate
from the zero frequency to the set maximum frequency (par. ID102). These parameters
give the possibility to set two different acceleration/deceleration time sets for one appli­cation. The active set can be selected with the programmable signal DIN3 (par. ID301).

When the frequency converter is decelerating the motor, the inertia of the motor and the
load are fed into an external brake resistor. This enables the frequency converter to
decelerate the load with a torque equal to that of acceleration (provided that the correct
brake resistor has been selected). See separate Brake resistor installation manual.

508 DC-braking time at stop

Determines if braking is ON or OFF and the braking time of the DC-brake when the
motor is stopping. The function of the DC-brake depends on the stop function,
parameter ID506.

0 DC-brake is not used
>0 DC-brake is in use and its function depends on the Stop function,

(param. ID506). The DC-braking time is determined with this parameter.

Par. ID506 = 0; Stop function = Coasting:

After the stop command, the motor coasts to a stop without control of the frequency
converter.

With DC-injection, the motor can be electrically stopped in the shortest possible time,
without using an optional external braking resistor.

The braking time is scaled according to the frequency when the DC-braking starts. If the
frequency is ≥ the nominal frequency of the motor, the set value of parameter ID508
determines the braking time. When the frequency is ≤10% of the nominal, the braking
time is 10% of the set value of parameter ID508.

519 Flux braking current

Defines the flux braking current value. This value can be set between 0.4*IH and the

520 Flux brake

Instead of DC braking, flux braking is a useful way to raise the braking capacity in cases
where additional brake resistors are not needed.
When braking is needed, the frequency is reduced and the flux in the motor is increased,
which in turn increases the motor's capability to brake. Unlike DC braking, the motor
speed remains controlled during braking.

The flux braking can be set ON or OFF.

0 = Flux braking OFF
1 = Flux braking ON

Note: Flux braking converts the energy into heat at the motor, and should be used
intermittently to avoid motor damage.

603 Voltage at field weakening point

Above the frequency at the field weakening point, the output voltage remains at the set
maximum value. Below the frequency at the field weakening point, the output voltage
depends on the setting of the U/f curve parameters. See parameters ID109, ID108, ID604
and ID605.
When the parameters ID110 and ID111 (nominal voltage and nominal frequency of the
motor) are set, the parameters ID602 and ID603 are automatically given the correspond­ing values. If you need different values for the field weakening point and the maximum
output voltage, change these parameters after setting the parameters ID110 and ID111.

If the programmable U/f curve has been selected with parameter ID108 this parameter
defines the middle point frequency of the curve. See Figure 3.

regulator controls the output frequency taking the supply fluctuations into account.

2 Controller switched on (with ramping) = Controller adjusts OP freq. up to max.freq.

The motor name plate speed is used to calculate the nominal slip. This value is used to
adjust the voltage of motor when loaded. The name plate speed is sometimes a little

Identification Run is a part of tuning the motor and the drive specific parameters. It is a
tool for commissioning and service of the drive with the aim to find as good parameter
values as possible for most drives. The automatic motor identification calculates or
measures the motor parameters that are needed for optimum motor and speed control.

The drive is run without speed to identify the motor parameters. The motor is supplied
with current and voltage but with zero frequency.

2 = Identification with motor run

The drive is run with speed to identify the motor parameters.
Note: It is recommended to do the this identification test with no load on the motor for
best results.

The basic motor name plate data has to be set correctly before performing the identifi­cation run:

The automatic identification is activated by setting this parameter to the appropriate
value followed by a start command in the requested direction. The start command to the
drive has to be given within 20 s. If no start command is given within 20 s the identifi­cation run is cancelled and the parameter will be reset to its default setting. The iden­tification run can be stopped any time with normal stop command and the parameter is
reset to its default setting. In case identification run detects fault or other problems, the

Note: The value is set as a percentage of the motor name plate data, par. ID113
(Nominal current of motor), not the drive's nominal output current. The motor's nominal
current is the current that the motor can withstand in direct on-line use without being
overheated.

If you change the parameter Nominal current of motor, this parameter is automatically
restored to the default value.
Setting this parameter does not affect the maximum output current of the drive which is
determined by parameter ID107 alone. See chapter 9.2.

707 Motor thermal protection: Time constant

This time can be set between 1 and 200 minutes.

This is the thermal time constant of the motor. The bigger the motor, the bigger the time
constant. The time constant is the time within which the calculated thermal stage has
reached 63% of its final value.

The motor thermal time is specific to the motor design and it varies between different
motor manufacturers.

If the motor's t6–time (t6 is the time in seconds the motor can safely operate at six times
the rated current) is known (given by the motor manufacturer) the time constant
parameter can be set basing on it. As a rule of thumb, the motor thermal time constant
in minutes equals to 2xt6. If the drive is in stop stage the time constant is internally
increased to three times the set parameter value. The cooling in the stop stage is based
on convection and the time constant is increased. See also Figure 24.

Parameters ID720 to ID725 determine the maximum number of automatic restarts
during the trial time set by parameter ID718. The time count starts from the first
autorestart. If the number of faults occurring during the trial time exceeds the values of

7.2 Application specific variables in the monitor menu and fieldbus interface

1700 Monitoring value: ActualRatio * 2^16

Actual value of ratio after the ramp. 65536 counts = unity ratio.

1701 Monitoring value: Position error

Actual value of position error = Master position x actual ratio – Follower position.
1 count = 1 engineering distance unit. Positive error means follower lagging compared to
the master when running in the forward direction.

(V1.18)

1702 Fieldbus high resolution position error

Actual value of position error = Master position x actual ratio – Follower position.
65536 counts = 1 engineering space unit.

(V1.17)

1703 Fieldbus synchronization status register

The map of the status register is shown in Table 41.

1803 Accum SpaceError

Shows the accumulated Position Error in user units between Master and Follower. This
value will grow if Follower drive trips and the master continue to run before it is stopped.
(Normally Fault output from follower should stop the master drive when there is a fault
in follower)

NOTE: This value is resetted when synchronization is enabled again (B0).
Value is useful for correction of position error between master and follower when
filedbus control is used. In that case this value can be transferred to parameter P2.9.3.1
(ID 1805) to correct the error.
In that case, be sure to store the Accum Space Error value in controller before enabling
Synchronization again.

Engineering distance unit is defined by the user.
The Kinematic ratio is to be set up for the master (P2.9.1.1 … P2.9.1.4) and the follower drive
(P2.9.2.1 … P2.9.2.4). This describes the physical relationship between the master and follower
drive.

Synchronization Commands:
Can be performed by digital inputs (see P2.2.5.20, P2.2.5.21) or from fieldbus interface (see table 39)
Shaft synchronization mode has to be enabled to accept these commands.
Note: When Shaft synchronization is disabled the normal Multi-purpose speed control is active.

Sync Mode bit 1 Sync Mode bit 0 Action
0 0 Release synchronization
0 1 Engage synchronization
1 0 Use reference speed given

from selected reference place.

1 1 Freeze follower speed. Only

possible when synchronization
is engaged to master speed.

Phasing Commands:
Shaft synchronization mode has to be enabled and Sync mode B0=1 to accept these commands.
The phasing command is for exact position adjustment in user units of follower. It can be executed
when follower is in standstill or when running synchronized. The control bit BO has to be on to
accept phasing commands.
The maximum frequency is the speed limit during phasing.
Acceleration/Deceleration during phasing command is same as for engage/release synchronization

Change of gear ratio during run:
The ratio of the follower to the master speed and position can be dynamically changed by a ramped,
high resolution ratio control. Ratio can be changed by P2.9.2.9 from keypad.
If fieldbus control is used better use the 2 process datas selected by P2.7.10.
See Figure 36.

In I/O control the ratio can be changed by P2.9.2.11 dynamically with the trim +/- inputs connected to
digital inputs selected by P2.2.5.22 and P2.2.5.23.
Then the ratio is temporarily changed when the trim input is active.
Function is useful for changing of the gear ratio during running. See Figure 36.

Output signal for diagnostics:
Digital or relay outputs include a flag to signal changing value of the ratio and a flag to signal that
space synchronization has been achieved.
The Ratio changing output is set whenever a change in the ratio is requested and it remains on until
the ramp has reached the required value.
The Synchronization engaged output is set at the end of execution of the Engage synchronization
command, after the follower has been brought to master speed x ratio and space control loop is
activated. The Synchronization engaged output is cleared whenever a Release synchronization
command is issued or whenever a Freeze command is issued.
The Synchronization engaged output is also cleared whenever a Drive stop is requested or a fault
occurs.

9. APPENDICES

In this chapter you will find additional information on special parameter groups. Such groups are:



Closed Loop parameters (Chapter 9.1)



Parameters of Motor thermal protection (Chapter 9.2)



Parameters of Stall protection (Chapter 9.3)



Fieldbus control parameters (Chapter 9.4)

9.1 Closed loop parameters (ID’s 612 to 621)

Select the Closed loop control mode by setting value 3 or 4 for parameter ID600.
Closed loop control mode (see page 61) is used when enhanced performance near zero speed and
better static speed accuracy with higher speeds are needed. Closed loop control mode is based on
"rotor flux oriented current vector control". With this controlling principle, the phase currents are
divided into a torque producing current portion and a magnetizing current portion. Thus, the squirrel
cage induction machine can be controlled in a fashion of a separately excited DC motor.

Note: These parameters can be used with Vacon NXP drive only.

EXAMPLE:

Motor Control Mode = 3 (Closed loop speed control)

This is the usual operation mode when fast response times, high accuracy or controlled
run at zero frequencies are needed. Encoder board should be connected to slot C of the
control unit. Set the encoder P/R-parameter (P7.3.1.1). Run in open loop and check the
encoder speed and direction (V7.3.2.2). Change the direction parameter (P7.3.1.2) or switch
the phases of motor cables if necessary. Do not run if encoder speed is wrong. Program
the no-load current to parameter ID612 and set parameter ID619 (Slip Adjust) to get the
voltage slightly above the linear U/f-curve with the motor frequency at about 66% of the
nominal motor frequency. The Motor Nominal Speed parameter (ID112) is critical. The
Current Limit parameter (ID107) controls the available torque linearly in relative to motor
nominal current.

9.2 Parameters of motor thermal protection (ID’s 704 to 708):

General

The motor thermal protection is to protect the motor from overheating. The Vacon drive is capable of
supplying higher than nominal current to the motor. If the load requires this high current there is a
risk that the motor will be thermally overloaded. This is the case especially at low frequencies. At
low frequencies the cooling effect of the motor is reduced as well as its capacity. If the motor is
equipped with an external fan the load reduction at low speeds is small.
The motor thermal protection is based on a calculated model and it uses the output current of the
drive to determine the load on the motor.
The motor thermal protection can be adjusted with parameters. The thermal current I

load current above which the motor is overloaded. This current limit is a function of the output
frequency.
The thermal stage of the motor can be monitored on the control keypad display. See the product's
User's Manual.

specifies the

T

!

9.3 Parameters of stall protection (ID’s 709 to 712):

General

The motor stall protection protects the motor from short time overload situations such as one
caused by a stalled shaft. The reaction time of the stall protection can be set shorter than that of
motor thermal protection. The stall state is defined with two parameters, ID710 (Stall current) and
ID712 (Stall frequency limit). If the current is higher than the set limit and output frequency is lower
than the set limit, the stall state is true. There is actually no real indication of the shaft rotation. Stall
protection is a type of overcurrent protection.

9.4 Fieldbus control parameters (ID’s 850 to 859)

The Fieldbus control parameters are used when the frequency or the speed reference comes from
the fieldbus (Modbus, Profibus, DeviceNet etc.). With the Fieldbus Data Out Selection 1…8 you can
monitor values from the fieldbus.

CAUTION! The calculated model does not protect the motor if the airflow to the

motor is reduced by blocked air intake grill.

11. COMMISSIONING OF SHAFT SYNCHRONIZATION APPLICATION

Perform following steps during commissioning

1. Set correct Motor data by basic parameters P2.1.5-P2.1.9

2. Set parameters for kinematic gear ratio with parameters P2.9.1.1-P2.9.1.4 and P2.9.2.1­P2.9.2.4

3. Run automatic motor identification by RUN (2) if it is possible to disconnect the load. See
parameter P2.5.16. Go to step 5. If not possible do step 4.

4. Set magnetizing current P2.5.18.1 manually if it was not possible to perform step 2. (if
magnetizing current is set to 0 the magnetizing current is estimated by system software
based on given motor data)

5. Make test run in Open loop to check the encoder direction in Expander board menu. Swap
encoder channels A/B if encoder speed feedback is opposite than output frequency.

6. Change parameter P2.5.1 to 3 for Closed loop speed control. (Shaft synchronization works
only in closed loop speed control)

7. Check that pulses are coming to encoder channel 2 in follower (Expander board menu)

8. Set P2.1.1. Max frequency high enough to have a margin for regulation. If command speed
from master is higher than the maximum frequency allows the follower drive to run there

9. Set drive in run and enable synchronization and set Synch. mode B0 = 1

10. Run Master with very slow speed and check that follower is following

11. If rotation direction of follower is wrong. Swap encoder channels A/B on encoder board for
CH2.

12. Set parameters for mechanical brake in G2.3.8 If mechanical brake is used. Also program a
digital output ID445/ID446 for controlling the brake and eventual input, ID1602 for hardware
acknowledgement.
