Consequently, it is essential to comply with the instructions in this manual as well as local and national rules and safety regulations.

2.1.3 Safety Note

The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor, frequency converter or fieldbus may cause death, serious personal injury or damage to the equipment. Consequently, the instructions in this manual, as well as national and local rules and safety regulations, must be complied with.

Safety Regulations

1. The frequency converter must be disconnected from mains if repair work is to be carried out. Check that the mains supply has been disconnected and that the necessary time has passed before removing motor and mains plugs.

2. The [STOP/RESET] key on the LCP of the frequency converter does not disconnect the equipment from mains and is thus not to be used as a safety switch.

3. Correct protective earthing of the equipment must be established, the user must be protected against supply voltage, and the motor must be protected against overload in accordance with applicable national and local regulations.

4. The earth leakage currents are higher than 3.5 mA.

5. Protection against motor overload is set by par. 1-90 Motor Thermal Protection. If this function is desired, set par. 1-90 Motor Thermal Protection to data value [ETR trip] (default value) or data value [ETR warning]. Note: The function is initialized at 1.16 x rated motor current and rated motor frequency. For the North American market: The ETR functions provide class 20 motor overload protection in accordance with NEC.

6. Do not remove the plugs for the motor and mains supply while the frequency converter is connected to mains. Check that the mains supply has been disconnected and that the necessary time has passed before removing motor and mains plugs.

7. Please note that the frequency converter has more voltage inputs than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) and external 24 V DC have been installed. Check that all voltage inputs have been disconnected and that the necessary time has passed before commencing repair work.

Installation at high altitudes

380 - 500 V, enclosure A, B and C: At altitudes above 2 km, please contact Danfoss regarding PELV. 380 - 500 V, enclosure D, E and F: At altitudes above 3 km, please contact Danfoss regarding PELV. 525 - 690 V: At altitudes above 2 km, please contact Danfoss regarding PELV.

Warning against Unintended Start

1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the frequency converter is connected to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient.

2. While parameters are being changed, the motor may start. Consequently, the stop key [STOP/RESET] must always be activated; following which data can be modified.

3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload or a fault in the supply mains or the motor connection ceases.

Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.

Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load sharing (linkage of DC intermediate circuit), as well as the motor connection for kinetic back up. Refer to the Operating Instructions for further safety guidelines.

The frequency converter DC link capacitors remain charged after power has been disconnected. To avoid an electrical shock hazard, disconnect the frequency converter from the mains before carrying out maintenance. Wait at least as follows before doing service on the frequency converter:

2.1.4 Before Commencing Repair Work

1. Disconnect the frequency converter from mains

2. Disconnect DC bus terminals 88 and 89

3. Wait at least the time mentioned in section General Warning above

4. Remove motor cable

2.1.5 Special Conditions

Electrical ratings: The rating indicated on the nameplate of the frequency converter is based on a typical 3-phase mains power supply, within the specified voltage, current and temperature range, which is expected to be used in most applications.

The frequency converters also support other special applications, which affect the electrical ratings of the frequency converter. Special conditions which affect the electrical ratings might be:

•

Single phase applications

•

High temperature applications which require derating of the electrical ratings

•

Marine applications with more severe environmental conditions.

Other applications might also affect the electrical ratings.

Consult the relevant sections in this manual and in the VLT HVAC Drive Design Guide, MG.11.BX.YY for information about the electrical ratings.

3.2.5 Safety Requirements of Mechanical Installation

Pay attention to the requirements that apply to integration and field mounting kit. Observe the information in the list to avoid serious injury or equipment damage, especially when installing large units.

CAUTION!

The frequency converter is cooled by means of air circulation. To protect the unit from overheating, it must be ensured that the ambient temperature does not exceed the

maximum temperature stated for the frequency converter and that the 24-hour average temperature is not exceeded. Locate the maximum temperature and 24- hour average in the paragraph Derating for Ambient Temperature.

If the ambient temperature is in the range of 45 °C - 55 ° C, derating of the frequency converter will become relevant, see Derating for Ambient Temperature. The service life of the frequency converter is reduced if derating for ambient temperature is not taken into account.

3.2.6 Field Mounting

For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units are recommended.

3.2.7 Panel Through Mounting

A Panel Through Mount Kit is available for frequency converter series VLT HVAC Drive, VLT Aqua Drive and VLT AutomationDrive.

In order to increase heatsink cooling and reduce panel depth, the frequency converter may be mounted in a through panel. Furthermore the in-built fan can then be removed.

The kit is available for enclosures A5 through C2.

NOTE

This kit cannot be used with cast front covers. IP21 plastic cover must be used instead.

Information on ordering numbers is found in the Design Guide, section Ordering Numbers. More detailed information is available in the Panel Through Mount Kit instruction, MI.33.HX.YY, where yy=language code.

Very long control cables and analog signals may, in rare cases and depending on installation, result in 50/60 Hz earth loops due to noise from mains supply cables.

If this occurs, break the screen or insert a 100 nF capacitor between screen and chassis.

NOTE

The common of digital / analog inputs and outputs should be connected to separate common terminals 20, 39, and 55. This will avoid ground current interference among groups. For example, it avoids switching on digital inputs disturbing analog inputs.

NOTE

Control cables must be screened/armoured.

4.1.3 Fuses

Branch Circuit Protection In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear, machines etc., must be short-circuit and over-current protected according to the national/international regulations.

Short-circuit protection: The frequency converter must be protected against short-circuit to avoid electrical or fire hazard. Danfoss recommends using the fuses mentioned below to protect service personnel and equipment in case of an internal failure in the drive. The frequency converter provides full short-circuit protection in case of a shortcircuit on the motor output.

Over-current protection Provide overload protection to avoid fire hazard due to overheating of the cables in the installation. Over current protection must always be carried out according to national regulations. The frequency converter is equipped with an internal over current protection that can be used for upstream overload protection (ULapplications excluded). See par. 4-18 Current Limit in the VLT HVAC Drive Programming Guide . Fuses must be designed for protection in a circuit capable of supplying a maximum of 100,000 A

rms

(symmetrical), 500 V/600 V

maximum.

Over-current protection If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in the table below, which will ensure compliance with EN50178. In case of malfunction, not following the recommendation may result in unnecessary damage to the frequency converter.

4.1.11 How to Connect Motor - Introduction

See section General Specifications for correct dimensioning of motor cable cross-section and length.

•

Use a screened/armoured motor cable to comply with EMC emission specifications (or install the cable in metal conduit).

•

Keep the motor cable as short as possible to reduce the noise level and leakage currents.

•

Connect the motor cable screen/armour to both the decoupling plate of the frequency converter and to the metal of the motor. (Same applies to both ends of metal conduit if used instead of screen.)

•

Make the screen connections with the largest possible surface area (cable clamp or by using an EMC cable gland). This is done by using the supplied installation devices in the frequency converter.

•

Avoid terminating the screen by twisting the ends (pigtails), as this will spoil high frequency screening effects.

•

If it is necessary to break the continuity of the screen to install a motor isolator or motor relay, the continuity must be maintained with the lowest possible HF impedance.

Cable length and cross-section The frequency converter has been tested with a given length of cable and a given cross-section of that cable. If the crosssection is increased, the cable capacitance - and thus the leakage current - may increase, and the cable length must be reduced correspondingly.

Switching frequency When frequency converters are used together with sine wave filters to reduce the acoustic noise from a motor, the switching frequency must be set according to the sine wave filter instruction in par. 14-01 Switching Frequency.

Precautions while using Aluminium conductors Aluminium conductors are not recommended for cable cross sections below 35 mm. Terminals can accept aluminium conductors but the conductor surface has to be clean and the oxidation must be removed and sealed by neutral acid free Vaseline grease before the conductor is connected.

Furthermore, the terminal screw must be retightened after two days due to the softness of the aluminium. It is crucial to ensure the connection makes a gas tight joint, otherwise the aluminium surface will oxidize again.

All types of three-phase asynchronous standard motors can be connected to the frequency converter. Normally, small motors are star-connected (230/400 V, D/Y). Large motors are deltaconnected (400/690 V, D/Y). Refer to the motor name plate for correct connection mode and voltage.

Illustration 4.16: Terminals for motor connection

CAUTION!

In motors without phase insulation paper or other insulation reinforcement suitable for operation with voltage supply (such as a frequency converter), fit a sinewave filter on the output of the frequency converter. (Motors that comply with IEC 60034-17 do not require a Sine-wave filter).

5.2.3 Automatic Motor Adaptation (AMA)

AMA is an algorithm to measure the electrical motor parameters on a motor at standstill. This means that AMA itself does not supply any torque. AMA is useful when commissioning systems and optimising the adjustment of the frequency converter to the applied motor. This feature is particularly used where the default setting does not apply to the connected motor. Par. 1-29 Automatic Motor Adaptation (AMA) allows a choice of complete AMA with determination of all electrical motor parameters or reduced AMA with determination of the stator resistance Rs only. The duration of a total AMA varies from a few minutes on small motors to more than 15 minutes on large motors.

Limitations and preconditions:

•

For the AMA to determine the motor parameters optimally, enter the correct motor nameplate data in par. 1-20 Motor Power [kW] to par. 1-28 Motor Rotation Check.

•

For the best adjustment of the frequency converter, carry out AMA on a cold motor. Repeated AMA runs may lead to a heating of the motor, which results in an increase of the stator resistance, Rs. Normally, this is not critical.

•

AMA can only be carried out if the rated motor current is minimum 35% of the rated output current of the frequency converter. AMA can be carried out on up to one oversize motor.

•

It is possible to carry out a reduced AMA test with a Sine-wave filter installed. Avoid carrying out a complete AMA with a Sine-wave filter. If an overall setting is required, remove the Sine-wave filter while running a total AMA. After completion of the AMA, reinsert the Sine-wave filter.

•

If motors are coupled in parallel, use only reduced AMA if any.

•

Avoid running a complete AMA when using synchronous motors. If synchronous motors are applied, run a reduced AMA and manually set the extended motor data. The AMA function does not apply to permanent magnet motors.

•

The frequency converter does not produce motor torque during an AMA. During an AMA, it is imperative that the application does not force the motor shaft to run, which is known to happen with e.g. wind milling in ventilation systems. This disturbs the AMA function.

6 How to Operate the Frequency

Converter

6.1.1 Three Ways of Operating

The frequency converter can be operated in three ways:

1. Graphical Local Control Panel (GLCP), see 5.1.2

2. Numeric Local Control Panel (NLCP), see 5.1.3

3. RS-485 serial communication or USB, both for PC connection, see 5.1.4

If the frequency converter is fitted with fieldbus option, please refer to relevant documentation.

6.1.2 How to Operate Graphical LCP (GLCP)

The following instructions are valid for the GLCP (LCP 102).

The GLCP is divided into four functional groups:

1. Graphical display with Status lines.

2. Menu keys and indicator lights (LED's) - selecting mode, changing parameters and switching between display functions.

3. Navigation keys and indicator lights (LEDs).

4. Operation keys and indicator lights (LEDs).

Graphical display: The LCD-display is back-lit with a total of 6 alpha-numeric lines. All data is displayed on the LCP which can show up to five operating variables while in [Status] mode.

Display lines:

a. Status line: Status messages displaying icons and

graphics.

b. Line 1-2: Operator data lines displaying data and

variables defined or chosen by the user. By pressing the [Status] key, up to one extra line can be added.

c. Status line: Status messages displaying text.

The display is divided into 3 sections:

Top section (a) shows the status when in status mode or up to 2 variables when not in status mode and in the case of Alarm/ Warning.

The number of the Active Set-up (selected as the Active Set-up in par. 0-10 Active Set-up) is shown. When programming in another Set-up than the Active Set-up, the number of the Setup being programmed appears to the right in brackets.

The Middle section (b) shows up to 5 variables with related unit, regardless of status. In case of alarm/warning, the warning is shown instead of the variables.

The Bottom section (c) always shows the state of the frequency converter in Status mode.

It is possible to toggle between three status read-out displays by pressing the [Status] key. Operating variables with different formatting are shown in each status screen - see below.

Each parameter has a name and number which remain the same regardless of the programming mode. In the Main Menu mode, the parameters are divided into groups. The first digit of the parameter number (from the left) indicates the parameter group number.

All parameters can be changed in the Main Menu. The configuration of the unit (par. 1-00 Configuration Mode) will determine other parameters available for programming. For example, selecting Closed Loop enables additional parameters related to closed loop operation. Option cards added to the unit enable additional parameters associated with the option device.

Provides a voltage which is optimized for a squared torque load characteristic of the motor.

[2] Auto

Energy Optim. CT

Auto Energy Optimization Compressor [2]: For optimum energy efficient speed control of screw and scroll compressors. Provides a voltage which is optimized for a constant torque load characteristic of the motor in the entire range down to 15Hz but in addition the AEO feature will adapt the voltage exactly to the current load situation, thereby reducing energy consumption and audible noise from the motor. To obtain optimal performance, the motor power factor cos phi must be set correctly. This value is set in par. 14-43 Motor Cosphi. The parameter has a default value which is automatically adjusted when the motor data is programmed. These settings will typically ensure optimum motor voltage but if the motor power factor cos phi requires tuning, an AMA function can be carried out using par. 1-29 Automatic Motor Adaptation (AMA). It is very rarely necessary to adjust the motor power factor parameter manually.

Option: Function:

The frequency converter determines the motor temperature for motor protection in two different ways:

•

Via a thermistor sensor connected to one of the analog or digital inputs (par. 1-93 Thermistor Source).

•

Via calculation (ETR = Electronic Thermal Relay) of the thermal load, based on the actual load and time. The calculated thermal load is compared with the rated motor current I

NOTE

If operating with par. 1-00 Configuration Mode set for Open Loop [0], par. 3-03 Maximum Reference must be used.

NOTE

The dynamics of the PID controller will depend on the value set in this parameter. Please see also par. 20-93 PID Proportional Gain. Par. 20-13 and par. 20-14 also determine the feedback range when using feedback for display readout with par. 1-00 Configuration Mode set for Open Loop [0]. Same condition as above.

20-20 Feedback Function

Option: Function:

This parameter determines how the three possible feedbacks will be used to control the output frequency of the frequency converter.

[0] Sum Sum [0] sets up the PID Controller to use the sum

of Feedback 1, Feedback 2 and Feedback 3 as the feedback.

NOTE

Any unused feedbacks must be set to No Function in par. 20-00 Feedback 1 Source, par. 20-03 Feedback 2 Source, or par. 20-06 Feedback 3 Source.

The sum of Setpoint 1 and any other references that are enabled (see par. group 3-1*) will be used as the PID Controller’s set-point reference.

[1] Difference Difference [1] sets up the PID controller to use the

difference between Feedback 1 and Feedback 2 as the feedback. Feedback 3 will not be used with this selection. Only Setpoint 1 will be used. The sum of Setpoint 1 and any other references that are enabled (see par. group 3-1*) will be used as the PID controller’s set-point reference.

[2] Average Average [2] sets up the PID Controller to use the

average of Feedback 1, Feedback 2 and Feedback 3 as the feedback.

NOTE

The sum of Setpoint 1 and any other references that are enabled (see par. group 3-1*) will be used as the PID Controller’s setpoint reference.

[4] Maximum Maximum [4] sets up the PID Controller to

compare Feedback 1, Feedback 2 and Feedback 3 and use the highest value as the feedback.

NOTE

Any unused feedbacks must be set to No Function in par. 20-00 Feedback 1 Source, par. 20-03 Feedback 2 Source, or par. 20-06 Feedback 3 Source.

Only Setpoint 1 will be used. The sum of Setpoint 1 and any other references that are enabled (see par. group 3-1*) will be used as the PID Controller’s setpoint reference.

[5] Multi

Setpoint Min

Multi-setpoint minimum [5] sets up the PID Controller to calculate the difference between Feedback 1 and Setpoint 1, Feedback 2 and Setpoint 2, and Feedback 3 and Setpoint 3. It will use the feedback/setpoint pair in which the feedback is the farthest below its corresponding setpoint reference. If all feedback signals are above their corresponding setpoints, the PID Controller will use the feedback/setpoint pair in which the difference between the feedback and setpoint is the least.

NOTE

If only two feedback signals are used, the feedback that is not to be used must be set to No Function in par. 20-00 Feedback 1 Source, par. 20-03 Feedback 2 Source or par. 20-06 Feedback 3 Source. Note that each setpoint reference will be the sum of its respective parameter value (par. 20-21 Setpoint 1, par. 20-22 Setpoint 2 and par. 20-23 Setpoint 3) and any other references that are enabled (see par. group 3-1*).

20-20 Feedback Function

Option: Function:

[6] Multi

Setpoint Max

Multi-setpoint maximum [6] sets up the PID Controller to calculate the difference between Feedback 1 and Setpoint 1, Feedback 2 and Setpoint 2, and Feedback 3 and Setpoint 3. It will use the feedback/setpoint pair in which the feedback is farthest above its corresponding setpoint reference. If all feedback signals are below their corresponding setpoints, the PID Controller will use the feedback/setpoint pair in which the difference between the feedback and the setpoint reference is the least.

NOTE

Any unused feedback must be set to “No function” in its Feedback Source parameter: Par. 20-00 Feedback 1 Source, par. 20-03 Feedback 2 Source or par. 20-06 Feedback 3 Source.

The feedback resulting from the function selected in par. 20-20 Feedback Function will be used by the PID Controller to control the output frequency of the frequency converter. This feedback can also be shown on the frequency converter’s display, be used to control a frequency converter's analog output, and be transmitted over various serial communication protocols.

The frequency converter can be configured to handle multi zone applications. Two different multi zone applications are supported:

•

Multi zone, single setpoint

•

Multi zone, multi setpoint

The difference between the two is illustrated by the following examples:

Example 1 – Multi zone, single setpoint In an office building, a VAV (variable air volume) VLT HVAC Drive system must ensure a minimum pressure at selected VAV boxes. Due to the varying pressure losses in each duct, the pressure at each VAV box cannot be assumed to be the

same. The minimum pressure required is the same for all VAV boxes. This control method can be set up by setting par. 20-20 Feedback Function to option [3], Minimum, and entering the desired pressure in par. 20-21 Setpoint 1. The PID

Controller will increase the speed of the fan if any one feedback is below the setpoint and decrease the speed of the fan if all feedbacks are above the setpoint.

Example 2 – Multi zone, multi setpoint The previous example can be used to illustrate the use of multi zone, multi setpoint control. If the zones require different pressures for each VAV box, each setpoint may be specified in par. 20-21 Setpoint 1, par. 20-22 Setpoint 2 and par. 20-23 Setpoint 3. By selecting Multi setpoint minimum, [5], in par. 20-20 Feedback Function, the PID Controller will increase the speed of the fan if any one of the feedbacks is below its setpoint and decrease the speed of the fan if all feedbacks are above their individual setpoints.

This parameter defines the application response. The default mode should be sufficient for most applications. If the application response speed is known, it can be selected here. This will decrease the time needed for carrying out PID autotuning. The setting has no impact on the value of the tuned parameters and is used only for the autotuning sequence.

20-72 PID Output Change

Range: Function:

0.10* [0.01 -

This parameter sets the magnitude of step change during autotuning. The value is a percentage of full speed. I.e. if maximum output frequency inpar. 4-13 Motor Speed High Limit [RPM]/ par. 4-14 Motor Speed High Limit [Hz] is set to 50 Hz,

0.10 is 10% of 50Hz, which is 5Hz. This parameter should be set to a value resulting in feedback changes of between 10% and 20% for best tuning accuracy.

20-73 Minimum Feedback Level

[Application dependant]

The minimum allowable feedback level should be entered here in User units as defined in par. 20-12 Reference/Feedback Unit. If the level falls below par. 20-73 Minimum Feedback Level, autotuning is aborted and an error message will appear on the LCP.

frequency to decrease when the feedback is greater than the setpoint reference. This is common for pressure-controlled supply fan and pump applications.

When the frequency converter is first started, it initially ramps up to this output speed in Open Loop Mode, following the active Ramp Up Time. When the output speed programmed here is reached, the frequency converter will automatically switch to Closed Loop Mode and the PID Controller will begin to function. This is useful in applications in which the driven load must first quickly accelerate to a minimum speed when it is started.

If (Error x Gain) jumps with a value equal to what is set in par. 20-14 Maximum Reference/Feedb. the PID controller will try to change the output speed equal to what is set in par. 4-13 Motor Speed High Limit [RPM] / par. 4-14 Motor Speed High Limit [Hz] but in practice of course limited by this setting. The proportional band (error causing output to change from 0-100%) can be calculated by means of the formula:

(

)

(

)

NOTE

Always set the desired for par. 20-14 Maximum Reference/Feedb. before setting the values for the PID controller in parameter group 20-9*.

20-94 PID Integral Time

Range: Function:

20.00 s

[0.01 -

10000.00 s]

Over time, the integrator accumulates a contribution to the output from the PID controller as long as there is a deviation between the Reference/Setpoint and feedback signals. The contribution is proportional to the size of the deviation. This ensures that the deviation (error) approaches zero. Quick response on any deviation is obtained when the integral time is set to a low value. Setting it too low, however, may cause the control to become unstable. The value set, is the time needed for the integrator to add the same contribution as the proportional part for a certain deviation. If the value is set to 10,000, the controller will act as a pure proportional controller with a Pband based on the value set in par. 20-93 PID Proportional Gain. When no deviation is present, the output from the proportional controller will be 0.

consumption is automatically measured and stored. Before enabling Auto Set Up:

1. Close valve(s) in order to create a no flow condition

2. The frequency converter must be set for Open Loop (par. 1-00 Configuration Mode). Note that it is important also to set par. 1-03 Torque Characteristics.

NOTE

22-82 Work Point Calculation

Option: Function:

From the data sheet showing characteristics for the specific equipment at different speeds, simply reading across from the H

DESIGN

point and the

DESIGN

point allows us to find point A, which is the System Design Working Point. The pump characteristics at this point should be identified and the associated speed programmed. Closing the valves and adjusting the speed until H

MIN

has been achieved allows the speed at the no flow point to be identified. Adjustment of par. 22-81 Square-linear Curve Approx- imation then allows the shape of the control curve to be adjusted infinitely.

Example 2: Speed at System Design Working Point is not known: Where the Speed at System Design Working Point is unknown, another reference point on the control curve needs to be determined by means of the data sheet. By looking at the curve for the rated speed and plotting the design pressure (H

DESIGN

Point C) the flow at that pressure Q

RATED

can be determined. Similarly, by plotting the design flow (Q

DESIGN

, Point D). the pressure HD at that flow can be determined. Knowing these two points on the pump curve, along with H

MIN

as described above, allows the frequency converter to calculate the reference point B and thus to plot the control curve which will also include the System design Working Point A.

7.3.1 Parameter Set-Up

Group Title Function

0- Operation and Display Parameters used to program the fundamental functions of the frequency converter and the LCP

including: selection of language; selection of which variables are displayed at each position in the display (e.g. static duct pressure or condenser water return temperature can be displayed with the setpoint in small digits in the top row and feedback in large digits in the centre of the dispay); enabling/disabling of the LCP keys/buttons; passwords for the LCP; upload and download of commissioned parameters to/from the LCP and setting the built in clock.

1- Load / Motor Parameters used to configure the frequency converter for the specific application and motor includ-

ing: open or closed loop operation; type of application such as compressor, fan or centrifual pump; motor nameplate data; auto-tuning of the drive to the motor for optimum performance; flying start (typically used for fan applications) and motor thermal protection.

2- Brakes Parameters used to configure braking functions of the frequency converter which although not

common in many HVAC applications, can be useful on special fan applications. Parameters including: DC braking; dymamic/resistor braking and over voltage control (which provides automatic adjustment of the deceleration rate (auto-ramping) to avoid tripping when decelerating large inertia fans)

3- Reference / Ramps Parameters used to program the minimum and maximum reference limits of speed (RPM/Hz) in

open loop or in actual units when operating in closed loop); digital/preset references; jog speed; definition of the source of each reference (e.g. which analog input the reference signal is connected to); ramp up and down times and digital potentiometer settings.

4- Limits / Warnings Parameters used to program limits and warnings of operation including: allowable motor direction;

minimum and maximum motor speeds (e.g. in pump applications it is typical to program a minimum speed to approx 30-40% to ensure pump seals are adequately lubricated at all times, avoid cavitation and ensure adequate head is produced at all times to create flow); torque and current limits to protect the pump, fan or compressor driven by the motor; warnings for low/high current, speed, reference, and feedback; missing motor phase protection; speed bypass frequencies including semi-automatic setup of these frequencies (e.g. to avoid resonance conditions on cooling tower and other fans).

5- Digital In / Out Parameters used to program the functions of all digital inputs, digital outputs, relay outputs, pulse

inputs and pulse outputs for terminals on the control card and all option cards.

6- Analog In / Out Parameters used to program the functions associated with all analog inputs and analog outputs for

the terminals on the control card and General Purpose I/O option (MCB 101) (note: NOT Analog I/O option MCB 109, see parameter group 26-00) including: analog input live zero timeout function (which for example can be used to command a cooling tower fan to operate at full speed if the condenser water return sensor fails); scaling of the analog input signals (for example to match the analog input to the mA and pressure range of a static duct pressure sensor); filter time constant to filter out electrical noise on the analog signal which can sometimes occur when long cables are installed; function and scaling of the analog outputs (for example to provide an analog output representing motor current or kW to an analog input of a DDC controller) and to configure the analog outputs to be controlled by the BMS via a high level interface (HLI) (e.g. to control a chilled water valve) including ability to define a default value of these outputs in the event of the HLI failing.

13- Smart Logic Controller Parameters used to configure the built in Smart Logic Controller (SLC) which can be used for simple

functions such as comparators (e.g. if running above xHz, activate output relay), timers (e.g. when a

start signal is applied, first activate output relay to open supply air damper and wait x seconds

before ramping up) or a more complex sequence of user defined actions executed by the SLC when

the associated user defined event is evaluated as TRUE by the SLC. (For example, initiate an

economiser mode in a simple AHU cooling application control scheme where there is no BMS. For

such an application the SLC can monitor the outside air relative humidity and if it is below a defined

value, the supply air temperature setpoint could be automatically increased. With the frequency

converter monitoring the outside air relative humidity and supply air temperature via it’s analog

inputs and controlling the chilled water valve via one of the extended PI(D) loops and an analog

output, it would then modulate that valve to maintain a higher supply air temperature). The SLC

can often replace the need for other external control equipment. 14- Special Functions Parameters used to configure special functions of the frequency converter including: setting of the

switching frequency to reduce audible noise from the motor (sometimes required for fan applica-

tions); kinetic back-up function (especially useful for critical applications in semi-conductor installa-

tions where performance under mains dip/mains loss is important); mains imbalance protection;

automatic reset (to avoid the need for a manual reset of Alarms); energy optimisation parameters

(which typically do not need changing but enable fine tuning of this automatic function (if necessa-

ry) ensuring the frequency converter and motor combination operate at their optimum efficiency at

full and partial load conditions) and auto-derating functions (which enable the frequency converter

to continue operation at reduced performance under extreme operating conditions ensuring

maximum up time). 15- FC Information Parameters providing operating data and other drive information including: operating and running

hour counters; kWh counter; resetting of the running and kWh counters; alarm/fault log (where the

past 10 alarms are logged along with any associated value and time) and drive and option card

indentification parameters such as code number and software version. 16- Data Readouts Read only parameters which display the status/value of many operating variables which can be

displayed on the LCP or viewed in this parameter group. These parameters can be particularly

useful during commissioning when interfacing with a BMS via a high level interface. 18- Info & Readouts Read only parameters which display the last 10 prevantative maintenance log items, actions and

time and the value of analog inputs and outputs on the Analog I/O option card which can be partic-

ularly useful during commissioning when interfacing with a BMS via a high level interface. 20- FC Closed Loop Parameters used to configure the closed loop PI(D) controller which controls the speed of the

pump, fan or compressor in closed loop mode including: defining where each of the 3 possible

feedback signals come from (e.g. which analog input or the BMS HLI); conversion factor for each of

the feedback signals (e.g. where a pressure signal is used for indication of flow in an AHU or

converting from pressure to temperature in a compressor application); engineering unit for the

reference and feedback (e.g. Pa, kPa, m Wg, in Wg, bar, m3/s, m3/h, °C, °F etc); the function (e.g.

sum, difference, average, minimum or maximum) used to calculate the resulting feedback for single

zone applications or the control philosophy for multi-zone applications; programming of the

setpoint(s) and manual or auto-tuning of the PI(D) loop. 21- Extended Closed Loop Parameters used to configure the 3 extended closed loop PI(D) controllers which for example can

be used to control external actuators (e.g. chilled water valve to maintain supply air temperature in

a VAV system) including: engineering unit for the reference and feedback of each controller (e.g. °C,

°F etc); defining the range of the reference/setpoint for each controller; defining where each of the

references/setpoints and feedback signals come from (e.g. which analog input or the BMS HLI);

programming of the setpoint and manual or auto-tuning of the each of the PI(D) controllers.

22- Application Functions Parameters used to monitor, protect and control pumps, fans and compressors including: no flow

detection and protection of pumps (including auto-setup of this function); dry pump protection;

end of curve detection and protection of pumps; sleep mode (especially useful for cooling tower

and booster pump sets); broken belt detection (typically used for fan applications to detect no air

flow instead of using a ∆p switch installed across the fan); short cycle protection of compressors and

pump flow compensation of setpoint (especially useful for secondary chilled water pump applica-

tions where the ∆p sensor has been installed close to the pump and not acoss the furthest most

significant load(s) in the system; using this function can compensate for the sensor installation and

help to realise the maximum energy savings). 23- Time Based Functions Time based parameters including: those used to initiate daily or weekly actions based on the built in

real time clock (e.g. change of setpoint for night set back mode or start/stop of the pump/fan/

compressor start/stop of a external equipment); preventative maintenance functions which can be

based on running or operating hour time intervals or on specific dates and times; energy log

(especially useful in retrofit applications or where information of the actual historical load (kW) on

the pump/fan/compressor is of interest); trending (especially useful in retrofit or other applications

where there is an interest to log operating power, current, frequency or speed of the pump/fan/

compressor for analysis and a payback counter. 24- Application Functions 2 Parameters used to set-up Fire Mode and/or to control a bypass contactor/starter if designed into

the system. 25- Cascade Controller Parameters used to configure and monitor the built in pump cascade controller (typically used for

pump booster sets). 26- Analog I/O Option MCB 109 Parameters used to configure the Analog I/O option (MCB 109) including: definition of the analog

input types (e.g. voltage, Pt1000 or Ni1000) and scaling and definition of the analog output

functions and scaling.
