heat exchanger application

1. GENERAL

This application is aimed to be used in the Vacon liquid-cooled AC drive inside the Heat exchanger
unit.

The idea with the application is to maintain a constant flow of coolant through the heat exchanger
and through the Vacon liquid-cooled drive.

The user sets a certain speed for the pump of the heat exchanger unit that produces a sufficient flow
through the Vacon liquid-cooled drives to keep them cooled. This speed is NOT regulated but fixed
by a parameter set value.

The Vacon AC drive also handles the temperature of the water in the heat exchanger unit by
regulating the valve that handles the coolant intake to the heat exchanger element (from the
customer's system). This regulation is based on the temperature of the water in the pipes between
the outlet of the heat exchanger pump and the inlet of the cooling element of the Vacon liquid-cooled
drive.

The actual value of the temperature for the regulation comes from a sensor called FSA11. This is a
type of flow switch that measures both the temperature of the coolant and the flow in the pipes. If
there is not enough flow in the pipe the sensor gives a signal that tells the drive to stop due to
insufficient flow.

Vacon NX AC drives can be connected to the Profibus DP using a fieldbus board. The AC drive can
then be controlled, monitored and programmed from the Host system. Profibus fieldbus board
(OPT-C5) is normally included in the delivery of Vacon NX liquid-cooled drive Heat Exchanger
Solution. The Profibus fieldbus board must be installed in slot E on the control board of the AC drive.
For more information on the Profibus fieldbus board, see Vacon OPTC3/C5 Profibus Option Board
User Manual.

The standard delivery also includes I/O boards OPT-A1 (placed in slot A), OPT-A2 (placed in slot B)
and OPT-B5 (placed in slot C or D). The application, however, offers you more signals than the
standard set of I/O boards allows you to connect. If you wish to use one additional analogue input
signal and/or two additional analogue output signals, we recommend you to order Vacon I/O board
OPT-B4 and place it in the last free board slot (C or D).

4. 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
Manual).
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.

101 Minimum frequency
102 Maximum frequency

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

103 Acceleration time 1
104 Deceleration time 1

(2.1.3)

(2.1.4)

is applied to this parameter (see All-in-One Application

(2.1.1)
(2.1.2)

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).

105 Preset speed 1

Parameter values are automatically limited between the minimum and maximum
frequencies (par. ID101, ID102).

(2.1.15)

107 Current limit

This parameter determines the maximum motor current from the AC drive. The
parameter value range differs from size to size. When this parameter is changed the
stall current limit (ID710) is internally calculated to 90% of current limit.

108 U/f ratio selection

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. Use this default setting if there is no special need for
another setting.

Squared: 1 The voltage of the motor changes following 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.

Linear with flux optimisation:
3 The AC drive starts to search for the minimum motor current in order to save

energy, lower the disturbance level and the noise. This function can be used
in applications with constant motor load, such as fans, pumps etc.

109 U/f optimisation

Automatic
torque boost

(2.1.13)

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.

Description of parameters vacon • 23

EXAMPLE:

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

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

Option 1: Activate the Automatic torque boost.

Option 2: Programmable U/f curve
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.

Programmable U/f curve

(value 2). Increase zero point voltage

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 attention must be paid to cooling the motor. Use external
cooling for the motor if the temperature tends to rise too high.

110 Nominal voltage of motor

(2.1.6)

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 motor

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

112 Nominal speed of motor

Find this value nn on the rating plate of the motor.

113 Nominal current of motor

Find this value In on the rating plate of the motor.

(2.1.8)

(2.1.9)

115 Parameter conceal

With this parameter you can hide all other parameter groups except the basic parameter
group (P2.1).

Note! The factory default of this parameter is 1, i.e. all parameter groups except P2.1
are hidden. The other parameter groups cannot be browsed or edited before the value of
this parameter is set to 0.

0 = Disabled (all parameter groups can be browsed with the keypad)

118 PID controller gain

This parameter defines the gain of the PID controller. If the value of the parameter is set
to 100% a change of 10% in the error value causes the controller output to change by
10%. If the parameter value is set to 0 the PID controller operates as ID-controller.
See examples at parameter ID132 below.

119 PID controller I-time

The parameter ID119 defines the integration time of the PID controller. If this parameter
is set to 1.00 second a change of 10% in the error value causes the controller output to
change by 10.00%/s. If the parameter value is set to 0.00 s the PID controller will operate
as PD controller.

132 PID controller D-time

The parameter ID132 defines the derivation time of the PID controller. If this parameter
is set to 1.00 second a change of 10% in the error value during 1.00 s causes the
controller output to change by 10.00%. If the parameter value is set to 0.00 s the PID
controller will operate as PI controller.

Example 1:
In order to reduce the error value to zero, with the given values, the AC drive output
behaves as follows:

Given values:
Par. 2.1.12, P = 0%
Par. 2.1.13, I-time = 1.00 s
Par. 2.1.14, D-time = 0.00 s Min freq. = 0 Hz
Error value (setpoint – process value) = 10.00% Max freq. = 50 Hz

In this example, the PID controller operates practically as I-controller only.
According to the given value of parameter 2.1.13 (I-time), the PID output increases by 5
Hz (10% of the difference between the maximum and minimum frequency) every second
until the error value is 0.

Example 2:
Given values:

Par. 2.1.12, P = 100%
Par. 2.1.13, I-time = 1.00 s
Par. 2.1.14, D-time = 1.00 s Min freq. = 0 Hz
Error value (setpoint – process value) = ±10% Max freq. = 50 Hz

As the power is switched on, the system detects the difference between the setpoint and
the actual process value and starts to either raise or decrease (in case the error value is
negative) the PID output according to the I-time. Once the difference between the set­point and the process value has been reduced to 0 the output is reduced by the amount
corresponding to the value of parameter 2.1.13.
In case the error value is negative, the AC drive reacts reducing the output
correspondingly. See Figure 4.

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 AC drive.

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.

Defines the flux braking current value. The value setting range depends on the used
application.

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.

601 Switching frequency

Motor noise can be minimised using a high switching frequency. Increasing the switching
frequency reduces the capacity of the AC drive unit.
The range of this parameter depends on the size of the AC drive:

Table 31. Size-dependent switching frequencies

Note! The actual switching frequency might be reduced down to 1.5kHz by thermal
management functions. This has to be considered when using sine wave filters or
other output filters with a low resonance frequency.

(2.6.8)

602 Field weakening point

The field weakening point is the output frequency at which the output voltage reaches the
set (ID603) maximum value.

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

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 19.

717 Automatic restart: Wait time

Defines the time before the AC drive tries to automatically restart the motor after the
fault state has disappeared.

718 Automatic restart: Trial time

The Automatic restart function restarts the AC drive when the fault state has
disappeared and the waiting time has elapsed.

The trial time count starts from the first autorestart. If the number of faults occurring
during the trial time exceeds 3, the fault state becomes active. Otherwise the fault is
cleared after the trial time has elapsed and the next fault starts the trial time count
again.

If a single fault remains during the trial time, a fault state is true.

1575 PID output, dead band
1576 PID output, dead band delay

This function is designed to prevent wear and unwanted movements of the actuators, for
example valves.

Use Dead band parameter to define dead band area around the PID setpoint value
(temperature setpoint). The output of the PID controller will be locked, if the actual
temperature (measured temperature) stays in the dead band area for the set time.

Use Dead band delay parameter to set the time that the actual temperature must stay in
the dead band area, before the output of the PID controller is locked.

The output of the PID controller will be released, if the actual temperature goes outside
of the dead band area.

Note! This function is disabled when Dead Band = 0.
