1. SAFETY

This manual contains clearly marked warning information which is intended for your personal safety and to avoid any unintentional damage to the product or connected appliances.

Before installing, commissioning or using the frequency converter, please read the warning information contained in Vacon 20X Installation Manual.

Please read the following additional safety instructions carefully.

Only Vacon authorized, trained and qualified personnel are allowed to install, operate and maintain the drive.

1.1 Danger

These warnings are intended to personnel responsible for grounding the frequency converter.

Ignoring the following instructions can be extremely dangerous and may cause

death or severe injury.

Ground the frequency converter to ensure personnel safety and to reduce electromagnetic interference.

After disconnecting the AC drive from the mains or from the DC input supply, wait until the indicators on the keypad go out (if no keypad is attached, see the

indicators on the cover). Wait an additional 30 seconds before starting any work on the connections of Vacon 20X Drive. After expiration of this time, use measuring equipment to absolutely ensure that no

absence of voltage before starting any electrical work!

1.2 Warnings

2. SOLAR PUMP APPLICATION

The VACON® 20 CP/X drive contains a preloaded application for instant use.

The parameters of this application are listed in chapter 3.3 of this manual and explained in more detail in chapter 4.

2.1 Specific functions of Vacon Solar pump application

The Vacon Solar Pump allows flexible use of VACON® 20 CP/X frequency converters. This dedicated application SW was developed to drive a Solar Pump with an optimized MPPT (Maximum Power Point Tracking) for 20X supplied by Solar Panels.

The MPPT is based on 4 parallel algorithms:

• Feed-Forward Controller (to follow the radiation variations)

• Correction Controller (to compensate the temperature variations)

• Oscillation Damping Regulator (to prevent the panel entering in the “current source” branch of the characteristic)

• Local Maxima logic (to prevent the regulator from being trapped in a local maximum lower than absolute maximum)

Features

The MPP Tracker controls DC voltage reference in order to find the maximum power.

The drive can be controlled through I/O terminals, a fieldbus or the optional keypad.Two programmable control places and sources for the frequency reference are available, for easy local/remote control.

Frequency reference can be direct (analogue input, preset speeds or fieldbus) or controlled by the internal PID regulator.

All the functionalities can be controlled through a fieldbus.

The motor identification function allows automatic optimization of the voltage/frequency curve, for a optimal torque response also at low motor speed.

It is possible to install one optional board for I/O expansion.

Underload protection can be managed by measuring Motor torque (standard sensorless mode) or by measuring the water flow with a flow meter sensor. This sensor can be an analogue signal or a digital input. With this sensor it is possible to measure the water flow [litres/min] and the total volume of the water flow [m

Sleep mode can be enabled or disabled with a parameter.

Digital inputs can be used to measure water levels (minimum and maximum).

2.3 Optional boards

One optional I/O expansion board can be installed into the slot on the right side of the drive. The following boards are supported:

OPTB1: 6 Digital Inputs-Outputs

The first 3 terminals are reserved as digital inputs (DIN7, DIN8, DIN9). The second 3 terminals can be used as inputs (DIN10, DIN11, DIN12) or digital outputs (EO1, EO2, EO3). The number of terminals used as input must be declared in parameter P2.24 (hidden if the board is not installed). This number determines the higher value for the selection of the digital input connected to a certain logical function. It also changes the visibility of parameters for the selection of digital outputs function (P5.9, P5.10, P5.11).

OPTB2: 1 Thermistor Input, 2 Relays Outputs

3.3.9 Group Protections: Menu PAR G9

NOTE!

Parameters of Motor thermal protection (P9.11 to P9.14 and P9.21-P9.22)

The motor thermal protection is to protect the motor from overheating. The 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 fies the 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 chapter 2.

Visibility of the group depends on P1.16.

speci-

If you use long motor cables (max. 100m) together with small drives (≤1.5 kW) the motor current measured by the drive can be much higher than the actual motor current due to capacitive currents in the motor cable.

Consider this when setting up the motor thermal protection functions. The calculated model does not protect the motor if the airflow to the motor is

reduced by blocked air intake grill. The model starts from zero if the control board is powered off.

Parameters of Stall protection (P9.4 to P9.6)

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, P9.5 ( and P9.6 ( rent limiter has reduced the output frequency below the P9.6 for the time P9.5 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.

vacon • 29 Description of Groups

Parameters of Underload protection (P9.7 to P9.10)

The purpose of the motor underload protection is to ensure that there is load on the motor when the drive is running. If the motor loses its load there might be a problem in the process, e.g. a broken belt or a dry pump.

Motor underload protection can be adjusted by setting the underload curve with parameters P9.8 (Underload protection: Field weakening area load) and P9.9 (

frequency load

), see below. The underload curve is a squared curve set between the zero fre-

Underload protection: Zero

quency and the field weakening point. The protection is not active below 5Hz (the underload time counter is stopped).

The torque values for setting the underload curve are set in percentage which refers to the nominal torque of the motor. The motor's name plate data, parameter motor nominal current and the drive's nominal current I

are used to find the scaling ratio for the internal torque val-

ue. If other than nominal motor is used with the drive, the accuracy of the torque calculation decreases.

Consider this when setting up the motor thermal protection functions.

Sleep in solar mode can be managed according to P12.12 and P12.13 When P14.20 =1, the drive will stop if the output frequency is below the value in P12.12, for the time in P12.13. It will restart as after a stop due to low power. Sleep function allows to program a minimum frequency P1.1 that is below the efficient range of the pump. MPPT can reach this low value, leading to a minimum output power and avoiding to stop the drive in case of temporary reduced irradiation. If the condition persists, sleep logic will then stop the drive.

4. PARAMETER DESCRIPTION

Due to its user-friendliness and simplicity of use, the most parameters only require a basic description which is given in the parameter tables in chapter 2.2. In this chapter, you will find additional information on certain more advanced parameters. Should you not find the information you need contact your distributor.

4.1 Basic Parameters

P1.1 MIN FREQUENCY

Minimum frequency reference.

NOTE: When drive is fed by solar power, if available power is not sufficient to maintain dc voltage above the minimum and frequency above the minimum, the drive will be stopped.

NOTE: if motor current limit is reached, actual output frequency might be lower than this parameter. If this is not acceptable, stall protection should be activated.

P1.2 M

Maximum frequency reference.

P1.3 A

Ramp time, referred to variation from zero frequency to max frequency.

A specific acceleration time from zero to minimum frequency is available (P2.9).

Normal acceleration time (P1.3) is active only in case power is from mains supply.

P1.4 D

Ramp time, referred to variation from max frequency to zero.

Normal deceleration time (P1.4) is active in mains supply and in case the external frequency reference is lowered below the reference of maximum power. It is also active when start command falls and ramping stop is programmed (stop mode is anyway by coasting, when the output frequency is below minimum).

Specific acceleration and deceleration time are used during power regulation. They are available as parameters in MPPT group, but it is suggested not to change them, unless needed because of stability issues.

P1.5 C

AX FREQUENCY

CCELERATION TIME

ECELERATION TIME

URRENT LIMIT

This parameter determines the maximum motor current from the AC drive. The parameter value range differs from size to size. When the current limit is active the drive output frequency is decreased.

NOTE: This is not an overcurrent trip limit.

P1.11 C

Run and direction control. A second control place is programmable in P2.14.

4: Keypad

5: Fieldbus

6: AI1 + AI2

7: Max Frequency

External frequency reference is available with the usual logics.

When the drive is fed from solar panels, the external reference is used as the upper limit of the algorithm searching for maximum power. A low external reference can therefore limit the power below the maximum available.

Note! the drive will not reach the external reference, if the power from panels is not sufficient.

4.2 Advanced settings

P2.1 START/STOP LOGIC

These logics are based on Start sign 1 and Start sign 2 signals (defined with P4.1 and P4.2). Usually they are coupled to inputs DIN1 and DIN2.

Values 0...3 offer possibilities to control the starting and stopping of the AC drive with digital signal connected to digital inputs.

Selection name Note

The function takes place when one contact is closed. If the other contact is closed while the first is still closed, the drive will stop and issue alarm A55

The function takes place when the contacts are closed.

Run command is set when both Start 1 and Start 2 signals are high. It is reset when both the start signals are low. This can be used for a simple tank level control with hysteresis: if the tank has to be filled, two NC contact sensors will be placed at minimum and maximum levels. The drive will start below the minimum and stop above the maximum. If the tank has to be emptied, two NO contact sensors have to be used. The drive will start above the maximum and stop below the minimum.

Run command is set when Start 1 signal is high and a selectable analogue input is below (or above) a programmable threshold. This can be used for a tank level control, where the analogue measurement is used for both starting the pump and controlling the speed.

Run command is always active. Actual running condition is determined by DC voltage level available from the solar array.

The used stop mode is pages.

Start sign 1 activates causing the output frequency to rise. The motor runs forward.

Start sign 2 activates causing the motor drops to

0. Warning 55 appears on the keypad.

Start sign 1 is inactivated which causes the direction to start changing (FWD to REV) because Start sign 2 is still active.

Start sign 2 inactivates and the frequency fed to the motor drops to 0.

Start sign 2 activates again causing the motor to accelerate (REV) towards the set frequency.

Start sign 2 inactivates and the frequency fed to the motor drops to 0.

Start sign 1 activates and the motor accelerates (FWD) towards the set frequency

Run enable signal is set to FALSE, which drops

the frequency to 0. The run enable signal is configured with parameter P4.7.

Run enable signal is set to TRUE, which causes

the frequency to rise towards the set frequency because Start sign 1 is still active.

Keypad stop button is pressed and the frequency

Pushing the Start button on the keypad has no

effect on the drive status.

The keypad stop button is pushed again to stop

the drive.

The attempt to start the drive through pushing

the Start button is not successful even if Start sign 1 is inactive.

P8.1 MOTOR CONTROL MODE

0: Frequency control

1: Speed control (sensorless control)

In speed control, the motor slip is compensated.

Note: motor identification automatically sets this parameter to 1.

P8.2 F

Output frequency corresponding to max voltage.

Note: if P1.7 Nominal Frequency is changed, P8.2 will be set at same value.

P8.3 V

Motor voltage when frequency is above FWP, defined as% of nominal voltage.

Note: if P1.6 Nominal Voltage is changed, P8.3 will be set at 100%.

If the programmed maximum frequency is higher than motor nominal frequency, field weakening point is automatically set at maximum frequency and fwp voltage is set proportionally higher than 100%.

This could allow to exploit the higher voltage possibly coming from the panels.

In this situation the current limit has to be set properly, to prevent a motor overload.

If the drive is fed from mains, maximum output frequency will be limited by actual DC voltage, according to nominal U/f ratio.

P8.4 U/F RATIO SELECTION

0: linear

The voltage of the motor changes linearly as a function of output frequency from zero frequency voltage P8.7 to the field weakening point (FWP) voltage P8.3 at FWP frequency P8.2 This default setting should be used if there is no special need for another setting.

1: quadratic

(from voltage P8.7 at 0Hz, to voltage P8.3 at P8.2 frequency)

The voltage of the motor changes from zero point voltage P8.7 following a squared curve form from zero to the field weakening point P8.3. The motor runs under-magnetized below the field weakening point and produces less torque. Squared U/f ratio can be used in applications where torque demand is proportional to the square of the speed, e.g. in centrifugal fans and pumps.

2: programmable

The U/f curve can be programmed with three different points: Zero frequency voltage P8.7 (P1), Midpoint voltage/frequencyP8.6/P8.5 (P2) and Field weakening point P8.2/P8.3 (P3).

Programmable U/f curve can be used if more torque is needed at low frequencies. The optimal settings can automatically be achieved with Motor identification run.

Note: motor identification automatically sets this parameter to 2.

OTOR IDENTIFICATION

This procedure measures motor stator resistance and automatically sets U/f characteristic, to obtain good torque also at low speed.

Time at nominal current, to reach nominal temperature.

The time constant is the time within which the calculated thermal stage has reached 63% of its final value. The bigger the frame and/or slower the speed of the motor, the longer the time constant.

The motor thermal time is specific to the motor design and it varies between different motor manufacturers. The default value of the parameter varies from size to size.

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 2*t6. If the drive is in stop stage the time constant is internally increased to three times the set parameter value. The cooling in stop stage is based on convection and the time constant is increased.

The automatic reset function deletes fault state when the fault cause has been eliminated and the wait time P10.2 has elapsed. Parameter P10.4 determines the maximum number of automatic resets that can be effected during the trial time set by parameter P10.3. The time count starts from the first automatic reset. If the number of faults detected during the trial time exceeds the values of trials, the fault status becomes permanent and a reset command is needed.

Underload (dry run) fault is reset when P10.1 is active, without limitations in number, but according to a specific time schedule.

At first fault, autoreset is done after time 1 (P10.4). If underload fault happens again, after the number of tries defined in P10.7, delay becomes time 2 (P10.5).

Similarly, delay will change to time 3 (P10.6) if further tries are unsuccessful.

After a certain number of failed attempts (P14.1.3), the time between start attempts will change to long delay time P14.1.4.

If the drive can run continuously for the same long delay time, next start attempts will begin with short delay again. The same sequence is applied in case a running drive stops because of a temporary decrease in solar power.

Note! If the drive is supplied by mains, the drive is always enabled to start from external command.

4.13.2 MPPT

TART DC VOLTAGE

HORT RESTART DELAY

HORT RESTART DELAY TRIES

Generally, the MPP voltage of a panel is higher when the available power is high (good irradiation, low temperature).

The output power to the motor is considered an indicator of the panel state: if the drive can progressively increase motor speed and get a good amount of power, it means that the panel has basically “high” MPP voltage.

The DC voltage reference for the regulator is automatically changed by the MPP Tracker.

It results from four parallel algorithms:

-Feed-forward controller

-Correction controller

-Oscillation damping regulator

-Local Maxima logic

Service support: find your nearest Vacon service center at www.vacon.com

vacon • 77 Parameter description

4.13.2.1 MPPT feed-forward parameters

MPP feed-forward controller continuously changes the reference from Vmp@10% to Vmp@100%, according to actual motor power. The main purpose of this term is to follow variation of irradiation.

P14.5 V

MP AT 100% POWER

P14.6 VMP AT 10% POWER

The Vmp parameters should be obtained from panel characteristics, considering standard temperature and irradiation at 10% and 100% level.

If the second value is not known, subtract 50-60V from the first value as a rough estimation.

The accuracy of these values is not really critical, because the correction logic can easily compensate error of some tens of volts. It is better to set values possibly higher than the real ones, and let the correction decrease the voltage reference, to get maximum power.

P.14.7 P

ANEL/MOTOR RATIO

In case the solar panels have less maximum power than the motor, a value lower than 100% should be set in P14.7.

4.13.2.2 MPPT regulator

The drive tries to get the maximum power from solar panels by keeping the DC voltage at the optimum point (Max Power Point).

There is a PI regulator that changes the internal frequency reference, so that the power sent to the motor keeps the panels working on MPP.

The voltage reference can be monitored (V2.1) and compared to actual DC voltage (V1.9), to check the effect of gain tuning.

Continuous, low amplitude and high frequency oscillations mean gains too high.

Ramp times are meant to smooth the output frequency, but without introducing significant delay in response.

P14.8 P

GAIN

Proportional gain [Hz/V]. If set to 1.000, a variation of 1V on DC bus voltage causes a variation of 1Hz on frequency reference

Parameter description vacon • 78

4.13.2.3 MPPT correction parameters

This algorithm changes the DC voltage reference, to compensate temperature variations (usually slow) and to correct the error in feed-forward curve.

Correction can be up to +/- 150V.

The correction term is determined by “perturb-and-observe” logic (P&O).

P14.12 P&O

P14.13 P&O VOLTAGE STEP

DC voltage reference is periodically (at intervals defined by P14.12) increased or decreased by a small value (P14.13). If the variation brings a higher motor power, next variation will follow the same direction, otherwise it will be reversed.

A short perturb period (P14.12) makes the regulation faster, assuming that the PI gains are not too low (power variation has to complete within the period).

The correction term can be monitored (V2.2), to help the tuning of reference feed-forward. When the panels temperature is close to standard, 25°C, the correction term should result small (+/- 20 to 30V).

The correction decreases towards negative maximum as temperature increases.

The correction term increases towards positive maximum in case of low temperature.

If something different is observed, feed-forward values should be improved.

P14.14 P&O

P14.14 determines the variation in motor power, above which iteration of voltage reference change continues in the same direction.

Small value leads to a regulation very close to the maximum of the panel curve, with possible instability. Higher values lead to a more stable point, but with lower efficiency.

4.13.2.4 P&O in local max points

A panel with partial irradiation, or somehow defective, could cause a discontinuity on the power/voltage curve of the array. In this situation the basic P&O logic (perturb and observe) could lead to a local maximum point, that is not corresponding to maximum available power.

Figure 19.

P14.15 P&O LOCAL MAX STEP

To bypass discontinuity on power/voltage curve of array, after having reached a stable point, the P&O takes a bigger downward step (P14.15) in voltage. This step allows to overcome the local maximum and continue to search for the actual MPP.

If the point is the real MPP, the lower voltage reference will cause a drop in DC voltage and some oscillations, that are recognized and automatically damped by increasing the DC voltage reference.

The function can be disabled by programming P14.15= 0V.

P14.16 P&O

Further attempts to reach a higher MPP after an unsuccessful attempt will follow only after

LOCAL MAX TIME

the programmable masking time (P14.16).

P14.17 P&O

LOCAL MAX FREQ

The downward step is done only when output frequency is above minimum frequency + P14.17.

4.13.2.5 MPPT Oscillation Damping

If the power regulation enters the “current source” branch of the panel current/voltage characteristic, the typical result is a oscillation in DC voltage and output frequency. The damping logic recognizes oscillation in DC voltage and quickly increases the voltage reference correction term. This brings the panels back in “voltage source” branch.

P14.18 D

P14.18 parameter determines the amplitude of oscillation, to be recognized.

If the value is too low, normal variation in voltage level could be considered oscillation, and the DC voltage reference incorrectly increased.

P14.19 D

Oscillation is recognized when the logic sees three maximum and minimum point during the time defined by P14.19.

If the time is too short, the logic could fail with slow oscillations.

If the time is too long, spaced and unrelated min and max points could be confused with an oscillation.

P14.20 S

This parameter enables or disables the sleep fuction:

0: Disabled

1: Managed with P12.12 and P12.13

When P14.20 =1, the drive will stop if the output frequency is below the value in P12.12, for the time in P12.13. It will restart as after a stop due to low power.

AMPING SENSITIVITY

AMPING TIME

LEEP IN SOLAR MODE

Sleep function allows to program a minimum frequency P1.1 that is below the efficient range of the pump. MPPT can reach this low value, leading to a minimum output power and avoiding to stop the drive in case of temporary reduced irradiation. If the condition persists, sleep logic will then stop the drive.
