Introduction Design Guide
LCP
The local control panel (LCP) makes up a complete interface for control and programming of the frequency converter. The control panel is detachable on IP20 units and xed on IP54 units. It can be installed up to 3 m (9.8 ft) from the frequency converter, that is, in a front panel with the installation kit option.
Lsb
Least signicant bit.
MCM
Short for mille circular mil, an American measuring unit for cable cross-section. 1 MCM = 0.5067 mm2.
Msb
Most signicant bit.
On-line/O-line parameters
Changes to on-line parameters are activated immediately after the data value is changed. Press [OK] to activate o- line parameters.
PI controller
The PI controller maintains the desired speed, pressure, temperature, and so on, by adjusting the output frequency to match the varying load.
RCD
Residual current device.
Set-up
Parameter settings in 2 set-ups can be saved. Change between the 2 parameter set-ups and edit 1 set-up, while another set-up is active.
Slip compensation
The frequency converter compensates for the motor slip by giving the frequency a supplement that follows the measured motor load keeping the motor speed almost constant.
Smart logic control (SLC)
The SLC is a sequence of user-dened actions executed when the associated user-dened events are evaluated as true by the SLC.
Thermistor
A temperature-dependent resistor placed where the temperature is to be monitored (frequency converter or motor).
Trip
A state entered in fault situations, for example, if the frequency converter is subject to an overtemperature or when the frequency converter is protecting the motor, process, or mechanism. Restart is prevented until the cause of the fault does not exist and the trip state is canceled by activating reset or, sometimes, by being programmed to reset automatically. Do not use trip for personal safety.
Trip lock
A state entered in fault situations when the frequency converter is protecting itself and requiring physical intervention, for example, if the frequency converter is subject to a short circuit on the output. A locked trip can only be canceled by cutting o mains, removing the cause of the fault, and reconnecting the frequency converter. Restart is prevented until the trip state is canceled by activating reset or, sometimes, by being programmed to reset automatically. Do not use trip lock for personal safety.
VT characteristics
Variable torque characteristics used for pumps and fans.
+
VVC
If compared with standard voltage/frequency ratio control, voltage vector control (VVC+) improves the dynamics and the stability, both when the speed reference is changed and in relation to the load torque.

3.1.1 Why use a Frequency Converter for Controlling Fans and Pumps?
A frequency converter takes advantage of the fact that centrifugal fans and pumps follow the laws of propor­tionality for such fans and pumps. For further information, see chapter 3.1.3 Example of Energy Savings.
3.1.2 The Clear Advantage - Energy Savings
The clear advantage of using a frequency converter for controlling the speed of fans or pumps lies in the electricity savings. When comparing with alternative control systems and technologies, a frequency converter is the optimum energy control system for controlling fan and pump systems.

Illustration 3.2 Energy Savings with Frequency Converter
Solution
When using a frequency converter to reduce fan capacity to 60% - more than 50% energy savings may be obtained in typical applications.
3.1.3 Example of Energy Savings
As shown in Illustration 3.3, the ow is controlled by changing the RPM. By reducing the speed by only 20% from the rated speed, the ow is also reduced by 20%. This is because the ow is directly proportional to the RPM. The consumption of electricity, however, is reduced by 50%. If the system in question only needs to be able to supply a ow that corresponds to 100% a few days in a year, while the average is below 80% of the rated ow for the remainder of the year, the amount of energy saved is even more than 50%.

3.1.4 Comparison of Energy Savings
The Danfoss frequency converter solution oers major savings compared with traditional energy saving solutions such as discharge damper solution and inlet guide vanes (IGV) solution. This is because the frequency converter is able to control fan speed according to thermal load on the system, and the frequency converter has a built-in facility that enables the frequency converter to function as a building management system, BMS.
Illustration 3.3 shows typical energy savings obtainable with 3 well-known solutions when fan volume is reduced to 60%. As the graph shows, more than 50% energy savings can be achieved in typical applications.

Illustration 3.5 Energy Savings
Discharge dampers reduce power consumption. Inlet guide vanes oer a 40% reduction, but are expensive to install. The Danfoss frequency converter solution reduces energy consumption with more than 50% and is easy to install. It also reduces noise, mechanical stress, and wear-and-tear, and extends the life span of the entire application.

3.1.6 Better Control
If a frequency converter is used for controlling the ow or pressure of a system, improved control is obtained. A frequency converter can vary the speed of the fan or pump, obtaining variable control of ow and pressure. Furthermore, a frequency converter can quickly adapt the speed of the fan or pump to new ow or pressure conditions in the system. Simple control of process (ow, level, or pressure) utilizing the built-in PI control.

3.1.7 Star/Delta Starter or Soft Starter not Required
When larger motors are started, it is necessary in many countries to use equipment that limits the start-up current. In more traditional systems, a star/delta starter or soft starter is widely used. Such motor starters are not required if a frequency converter is used.
As illustrated in Illustration 3.8, a frequency converter does not consume more than rated current.
3.1.8 Using a Frequency Converter Saves Money
The example in chapter 3.1.9 Without a Frequency Converter shows that a frequency converter replaces other equipment. It is possible to calculate the cost of installing the 2 dierent systems. In the example, the 2 systems can be established at roughly the same price.
Use the VLT® Energy Box software that is introduced in chapter 1.5 Additional Resources to calculate the cost savings that can be achieved by using a frequency converter.

The following sections give typical examples of applications within HVAC.
3.1.12 Variable Air Volume
VAV or variable air volume systems, control both the ventilation and temperature to fulll the requirements of a building. Central VAV systems are considered to be the most energy-ecient method to air condition buildings. By designing central systems instead of distributed systems, a greater eciency can be obtained. The eciency comes from utilizing larger fans and larger chillers which have much higher eciencies than small motors and distributed air-cooled chillers. Savings are also seen from the decreased maintenance requirements.

3.1.14 Constant Air Volume
CAV, or constant air volume systems, are central ventilation systems usually used to supply large common zones with the minimum amounts of fresh tempered air. They preceded VAV systems and are therefore found in older multi-zoned commercial buildings as well. These systems preheat amounts of fresh air utilizing air handling units (AHUs) with a heating coil, and many are also used to air condition buildings and have a cooling coil. Fan coil units are frequently used to assist in the heating and cooling requirements in the individual zones.
3.1.15 The VLT Solution
With a frequency converter, signicant energy savings can be obtained while maintaining decent control of the building. Temperature sensors or CO2 sensors can be used as feedback signals to frequency converters. Whether controlling temperature, air quality, or both, a CAV system can be controlled to operate based on actual building conditions. As the number of people in the controlled area decreases, the need for fresh air decreases. The CO2 sensor detects lower levels and decreases the supply fans speed. The return fan modulates to maintain a static pressure setpoint or
airows.
xed dierence between the supply and return
With temperature control, especially used in air conditioning systems, as the outside temperature varies as well as the number of people in the controlled zone changes, dierent cooling requirements exist. As the temperature decreases below the setpoint, the supply fan can decrease its speed. The return fan modulates to maintain a static pressure setpoint. By decreasing the air ow, energy used to heat or cool the fresh air is also reduced, adding further savings. Several features of the Danfoss HVAC dedicated frequency converter can be utilized to improve the performance of the CAV system. One concern of controlling a ventilation system is poor air quality. The programmable minimum frequency can be set to maintain a minimum amount of supply air regardless of the feedback or reference signal. The frequency converter also includes a PI controller, which allows monitoring both temperature and air quality. Even if the temperature requirement is fullled, the frequency converter maintains enough supply air to satisfy the air quality sensor. The controller is capable of monitoring and comparing 2 feedback signals to control the return fan by maintaining a xed dierential airow between the supply and return ducts as well.

Cooling tower fans cool condenser-water in water-cooled chiller systems. Water-cooled chillers provide the most ecient means of creating chilled water. They are as much as 20% more ecient than air cooled chillers. Depending

on climate, cooling towers are often the most energy ecient method of cooling the condenser-water from chillers. They cool the condenser water by evaporation.
cooling tower fans applications. As the cooling tower fans drop below a certain speed, the eect the fan has on cooling the water becomes small. Also, when utilizing a gearbox to frequency control the tower fan, a minimum speed of 40–50% is required. The customer programmable minimum frequency setting is available to maintain this minimum frequency even as the feedback or speed reference calls for lower speeds.
The condenser water is sprayed into the cooling tower until the cooling towers ll to increase its surface area. The tower fan blows air through the ll and sprayed water to aid in the evaporation. Evaporation removes energy from the water dropping its temperature. The cooled water collects in the cooling towers basin where it is pumped back into the chillers condenser and the cycle is repeated.
Also as a standard feature, the frequency converter can be programmed to enter a sleep mode and stop the fan until a higher speed is required. Additionally, some cooling tower fans have undesirable frequencies that may cause vibrations. These frequencies can easily be avoided by programming the bypass frequency ranges in the frequency converter.
3.1.17 The VLT Solution
With a frequency converter, the cooling tower fans can be controlled to the required speed to maintain the condenser-water temperature. The frequency converters can also be used to turn the fan on and o as needed.

3.1.18 Condenser Pumps
Condenser water pumps are primarily used to circulate water through the condenser section of water cooled chillers and their associated cooling tower. The condenser water absorbs the heat from the chiller's condenser section and releases it into the atmosphere in the cooling tower. These systems are used to provide the most ecient means of creating chilled water, they are as much as 20% more ecient than air cooled chillers.
3.1.19 The VLT Solution
Frequency converters can be added to condenser water pumps instead of balancing the pumps with a throttling valve or trimming the pump impeller.
Using a frequency converter instead of a throttling valve simply saves the energy that would have been absorbed by the valve. This can amount to savings of 15–20% or more. Trimming the pump impeller is irreversible, thus if the conditions change and higher ow is required the impeller must be replaced.

3.1.20 Primary Pumps
Primary pumps in a primary/secondary pumping system can be used to maintain a constant ow through devices that encounter operation or control diculties when
33
exposed to variable ow. The primary/secondary pumping technique decouples the primary production loop from the secondary distribution loop. This allows devices such as chillers to obtain constant design ow and operate properly while allowing the rest of the system to vary in
ow.
As the evaporator ow rate decreases in a chiller, the chilled water begins to become overchilled. As this happens, the chiller attempts to decrease its cooling capacity. If the ow rate drops far enough, or too quickly, the chiller cannot shed its load suciently and the chiller’s safety trips the chiller requiring a manual reset. This situation is common in large installations especially when 2 or more chillers in parallel are installed if primary/ secondary pumping is not utilized.
3.1.21 The VLT Solution
Depending on the size of the system and the size of the primary loop, the energy consumption of the primary loop can become substantial. A frequency converter can be added to the primary system to replace the throttling valve and/or trimming of the impellers, leading to reduced operating expenses. 2 control methods are common:
Flow meter
Because the desired ow meter installed at the discharge of each chiller, can be used to control the pump directly. Using the built-in PI controller, the frequency converter always maintains the appropriate ow rate, even compensating for the changing resistance in the primary piping loop as chillers and their pumps are staged on and o.
Local speed determination
The operator simply decreases the output frequency until the design ow rate is achieved. Using a frequency converter to decrease the pump speed is very similar to trimming the pump impeller, except it does not require any labor, and the pump eciency remains higher. The balancing contractor simply decreases the speed of the pump until the proper ow rate is achieved and leaves the speed xed. The pump operates at this speed any time the chiller is staged on. Because the primary loop does not have control valves or other devices that can cause the system curve to change, and the variance due to staging pumps and chillers on and o is usually small, this xed speed remains appropriate. If the ow rate needs to be increased later in the system’s life, the frequency converter can simply increase the pump speed instead of requiring a new pump impeller.
ow rate is known and is constant, a

Secondary pumps in a primary/secondary chilled water pumping system distribute the chilled water to the loads from the primary production loop. The primary/secondary pumping system is used to hydronically de-couple 1 piping

loop from another. In this case, the primary pump is used to maintain a constant ow through the chillers while allowing the secondary pumps to vary in ow, increase control and save energy. If the primary/secondary concept is not used in the design of a variable volume system when the ow rate drops far enough or too quickly, the chiller cannot shed its load
the system curve instead of the pump curve. This results in the elimination of wasted energy and eliminates most of the overpressurization that 2-way valves can be subjected to. As the monitored loads are reached, the 2-way valves close down. This increases the dierential pressure measured across the load and the 2-way valve. As this dierential pressure starts to rise, the pump is slowed to maintain the control head also called setpoint value. This setpoint value is calculated by summing the pressure drop of the load and the 2-way valve together under design conditions.
properly. The chiller’s low evaporator temperature safety then trips the chiller requiring a manual reset. This situation is common in large installations especially when 2 or more chillers in parallel are installed.

Local reference forces the conguration mode to open­loop, independent on the setting of parameter 1-00 Conguration Mode.
For example, consider a pump application where the speed of a pump is to be controlled to ensure a constant static pressure in a pipe. The static pressure value is supplied to the frequency converter as the setpoint reference. A static

pressure sensor measures the actual static pressure in the pipe and supplies this data to the frequency converter as a

3.2.4 Control Structure Closed Loop
The internal controller allows the frequency converter to become a part of the controlled system. The frequency converter receives a feedback signal from a sensor in the system. It then compares this feedback to a setpoint
feedback signal. If the feedback signal is greater than the setpoint reference, the frequency converter slows the pump down to reduce the pressure. In a similar way, if the pipe pressure is lower than the setpoint reference, the frequency converter automatically speeds the pump up to increase the pressure provided by the pump.
reference value and determines the error, if any, between these 2 signals. It then adjusts the speed of the motor to correct this error.

While the default values for the closed-loop controller of
3.2.5 Feedback Conversion
the frequency converter often provide satisfactory performance, the control of the system can often be optimized by adjusting parameters.
In some applications, it may be useful to convert the feedback signal. One example of this is using a pressure signal to provide ow feedback. Since the square root of pressure is proportional to ow, the square root of the pressure signal yields a value proportional to the ow. See Illustration 3.20.

Illustration 3.21 Block Diagram Showing Remote Reference
The remote reference consists of:
Up to 8 preset references can be programmed in the frequency converter. The active preset reference can be selected using digital inputs or the serial communications bus. The reference can also be supplied externally, most commonly from an analog input. This external source is selected by 1 of the 3 reference source parameters (parameter 3-15 Reference 1 Source,
parameter 3-16 Reference 2 Source, and parameter 3-17 Reference 3 Source). All reference resources
and the bus reference are added to produce the total external reference. The external reference, the preset reference, or the sum of the 2 can be selected to be the active reference. Finally, this reference can by be scaled using parameter 3-14 Preset Relative Reference.

Preset references.
External references (analog inputs and serial communication bus references).

The scaled reference is calculated as follows:

If Y, parameter 3-14 Preset Relative Reference, is set to 0%, the reference is not aected by the scaling.

3.2.7 Tuning the Drive Closed-loop Controller
Once the frequency converter's closed-loop controller has been set up, test the performance of the controller. Often, its performance may be acceptable using the default
33
values of parameter 20-93 PI Proportional Gain and parameter 20-94 PI Integral Time. However, sometimes it
may be helpful to optimize these parameter values to provide faster system response while still controlling speed overshoot.
3.2.8 Manual PI Adjustment
Illustration 3.22 0.25–0.75 kW (0.34–1.0 hp), 200 V, Enclosure
1. Start the motor.
2. Set parameter 20-93 PI Proportional Gain to 0.3 and increase it until the feedback signal begins to oscillate. If necessary, start and stop the frequency converter or make step changes in the setpoint reference to attempt to cause oscillation.
3. Reduce the PI proportional gain until the feedback signal stabilizes.
4. Reduce the proportional gain by 40–60%.
5. Set parameter 20-94 PI Integral Time to 20 s and reduce it until the feedback signal begins to oscillate. If necessary, start and stop the frequency converter or make step changes in the setpoint reference to attempt to cause oscillation.
6. Increase the PI integral time until the feedback signal stabilizes.
7. Increase the integral time by 15–50%.

Ambient Running Conditions
3.3
The frequency converter has been designed to meet the IEC/EN 60068-2-3 standard, EN 50178 9.4.2.2 at 50 °C (122 °F).
The ambient temperature measured over 24 hours should be at least 5 °C (41 °F) lower than the maximum ambient temperature. If the frequency converter is operated at high ambient temperature, decrease the continuous output current.

General Aspects of EMC
3.4
3.4.1 Overview of EMC Emissions
Frequency converters (and other electrical devices) generate electronic or magnetic with their environment. The electromagnetic compatibility (EMC) of these eects depends on the power and the harmonic characteristics of the devices.
elds that may interfere
Liquids can be carried through the air and condense in the frequency converter and may cause corrosion of components and metal parts. Steam, oil, and salt water may cause corrosion of components and metal parts. In such environments, use equipment with enclosure rating IP54. As an extra protection, coated printed circuit boards can be ordered as an option (standard on some power sizes).
Airborne particles such as dust may cause mechanical, electrical, or thermal failure in the frequency converter. A typical indicator of excessive levels of airborne particles is dust particles around the frequency converter fan. In dusty environments, use equipment with enclosure rating IP54 or a cabinet for IP20/TYPE 1 equipment.
In environments with high temperatures and humidity, corrosive gases such as sulphur, nitrogen, and chlorine compounds cause chemical processes on the frequency converter components.
Such chemical reactions rapidly electronic components. In such environments, mount the equipment in a cabinet with fresh air ventilation, keeping aggressive gases away from the frequency converter. An extra protection in such areas is a coating of the printed circuit boards, which can be ordered as an option.
Before installing the frequency converter, check the ambient air for liquids, particles, and gases. This is done by observing existing installations in this environment. Typical indicators of harmful airborne liquids are water or oil on metal parts, or corrosion of metal parts.
Excessive dust particle levels are often found on instal­lation cabinets and existing electrical installations. One indicator of aggressive airborne gases is blackening of copper rails and cable ends on existing installations.
aect and damage the
Uncontrolled interaction between electrical devices in a system can degrade compatibility and impair reliable operation. Interference may take the form of mains harmonics distortion, electrostatic discharges, rapid voltage uctuations, or high-frequency interference. Electrical devices generate interference along with being aected by interference from other generated sources.
Electrical interference usually arises at frequencies in the range 150 kHz to 30 MHz. Airborne interference from the frequency converter system in the range 30 MHz to 1 GHz is generated from the inverter, the motor cable, and the motor. Capacitive currents in the motor cable coupled with a high dU/dt from the motor voltage generate leakage currents, as shown in Illustration 3.52. The use of a shielded motor cable increases the leakage current (see Illustration 3.52) because shielded cables have higher capacitance to ground than unshielded cables. If the leakage current is not ltered, it causes greater interference on the mains in the radio frequency range below approximately 5 MHz. Since the leakage current (I1) is carried back to the unit through the shield (I3), there is only a small electro-magnetic eld (I4) from the shielded motor cable according to Illustration 3.52.
The shield reduces the radiated interference, but increases the low-frequency interference on the mains. Connect the motor cable shield to the frequency converter enclosure as well as on the motor enclosure. This is best done by using integrated shield clamps to avoid twisted shield ends (pigtails). Pigtails increase the shield impedance at higher frequencies, which reduces the shield the leakage current (I4). If a shielded cable is used for relay, control cable, signal interface, and brake, mount the shield on the enclosure at both ends. In some situations, however, it is necessary to break the shield to avoid current loops.
eect and increases
If the shield is to be placed on a mounting plate for the frequency converter, the mounting plate must be made of metal, to convey the shield currents back to the unit. Moreover, ensure good electrical contact from the mounting plate through the mounting screws to the frequency converter chassis.

3.4.4 Overview of Harmonics Emission
A frequency converter takes up a non-sinusoidal current from mains, which increases the input current I
RMS
. A non­sinusoidal current is transformed with a Fourier analysis and split into sine-wave currents with dierent frequencies, that is, dierent harmonic currents In with 50 Hz basic frequency:
I
Hz 50 250 350
Table 3.8 Harmonic Currents
1
I
5
I
7
The harmonics do not aect the power consumption directly, but increase the heat losses in the installation (transformer, cables). So, in plants with a high percentage of rectier load, maintain harmonic currents at a low level to avoid overload of the transformer and high temperature in the cables.
Illustration 3.53 DC-link Coils
NOTICE
Some of the harmonic currents might disturb communi­cation equipment connected to the same transformer or cause resonance with power factor correction batteries.
To ensure low harmonic currents, the frequency converter is equipped with DC-link coils as standard. This normally reduces the input current I
The voltage distortion on the mains supply voltage depends on the size of the harmonic currents multiplied by the mains impedance for the frequency in question. The total voltage distortion THDv is calculated based on the individual voltage harmonics using this formula:

3.4.7 Immunity Requirements
The immunity requirements for frequency converters depend on the environment where they are installed. The requirements for the industrial environment are higher than the requirements for the home and environment. All Danfoss frequency converters comply with the requirements for the industrial environment and therefore comply also with the lower requirements for home and oce environment with a large safety margin.

3.6 Earth Leakage Current
WARNING
DISCHARGE TIME
Touching the electrical parts could be fatal - even after
33
the equipment has been disconnected from mains. Also make sure that other voltage inputs have been disconnected, such as load sharing (linkage of DC-link), and the motor connection for kinetic back-up. Before touching any electrical parts, wait at least the amount of time indicated in Table 2.1. Shorter time is allowed only if indicated on the nameplate for the specic unit.
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the frequency converter properly can result in death or serious injury.
Ensure the correct grounding of the equipment
by a certied electrical installer.
WARNING
RESIDUAL CURRENT DEVICE PROTECTION
This product can cause a DC current in the protective conductor. Where a residual current device (RCD) is used for protection in case of direct or indirect contact, only an RCD of Type B is allowed on the supply side of this product. Otherwise, apply another protective measure, such as separation from the environment by double or reinforced insulation, or isolation from the supply system by a transformer. See also application note Protection against Electrical Hazards. Protective grounding of the frequency converter and the use of RCDs must always follow national and local regulations.
Motor-generated overvoltage
The voltage in the DC link is increased when the motor acts as a generator. This occurs in following cases:
The load drives the motor (at constant output
frequency from the frequency converter), that is the load generates energy.
During deceleration (ramp-down) if the inertia
moment is high, the friction is low, and the ramp­down time is too short for the energy to be dissipated as a loss in the frequency converter, the motor, and the installation.
Incorrect slip compensation setting
(parameter 1-62 Slip Compensation) may cause higher DC-link voltage.
The control unit may attempt to correct the ramp if parameter 2-17 Over-voltage Control is enabled. The frequency converter turns o to protect the transistors and the DC-link capacitors when a certain voltage level is reached.
Mains drop-out
During a mains dropout, the frequency converter keeps running until the DC-link voltage drops below the minimum stop level, which is typically 15% below the frequency converter's lowest rated supply voltage. The mains voltage before the drop-out and the motor load determines how long it takes for the frequency converter to coast.
3.7.1 Motor Thermal Protection (ETR)
Danfoss uses ETR to protect the motor from being overheated. It is an electronic feature that simulates a bimetal relay based on internal measurements. The charac­teristic is shown in Illustration 3.56.
3.7 Extreme Running Conditions
Short circuit (motor phase-phase)
Current measurement in each of the 3 motor phases or in the DC-link, protects the frequency converter against short circuits. A short circuit between 2 output phases causes an overcurrent in the inverter. The inverter is turned o individually when the short circuit current exceeds the allowed value (alarm 16, Trip Lock). For information about protecting the frequency converter against a short circuit at the load sharing and brake outputs, see chapter 8.3.1 Fuses and Circuit Breakers.
Switching on the output
Switching on the output between the motor and the frequency converter is allowed. The frequency converter is not damaged in any way by switching on the output. However, fault messages may appear.

nominal. The Y-axis shows the time in seconds before the ETR cuts o and trips the frequency converter. The curves show the characteristic nominal speed at twice the nominal speed and at 0.2x the nominal speed.
It is clear that at lower speed the ETR cuts o at lower heat due to less cooling of the motor. In that way, the motor is protected from being overheated even at low speed. The ETR feature calculates the motor temperature based on actual current and speed.
3.7.2 Thermistor Inputs
The thermistor cutout value is >3 k.
Integrate a thermistor (PTC sensor) in the motor for winding protection.
Motor protection can be implemented using a range of techniques:
PTC sensor in motor windings.
Mechanical thermal switch (Klixon type).
Electronic thermal relay (ETR).
Example with digital input and 10 V power supply
The frequency converter trips when the motor temperature is too high. Parameter set-up: Set parameter 1-90 Motor Thermal Protection to [2] Thermistor Trip. Set parameter 1-93 Thermistor Source to [6] Digital Input 29.

Installation Design Guide
5.1.1 Mains and Motor Connection
The frequency converter is designed to operate all standard 3-phase asynchronous motors. For maximum cross-section on cables, see chapter 8.4 General Technical Data.
Use a shielded/armored motor cable to comply
with EMC emission this cable to both the decoupling plate and the motor.
Keep the motor cable as short as possible to
reduce the noise level and leakage currents.
For further details on mounting the decoupling
plate, see FC 101 Decoupling Plate Mounting Instruction.
Also see EMC-Correct Installation in
chapter 5.1.2 EMC-compliant Electrical Installation.
For details on how to connect the frequency
converter to mains and motor, see chapter
Connecting to Mains and Motor in the VLT® HVAC Basic Drive FC 101 Quick Guide.

5.1.2 EMC-compliant Electrical Installation
Pay attention to the following recommendations to ensure EMC-correct electrical installation.
Use only shielded/armored motor cables and
shielded/armored control cables.
Connect the shield to ground at both ends.
Avoid installation with twisted shield ends
(pigtails), because this may aect the shielding eect at high frequencies. Use the cable clamps
55
provided instead.
It is important to ensure good electrical contact
from the installation plate through the installation screws to the metal cabinet of the frequency converter.
Use starwashers and galvanically conductive
installation plates.
Do not use unshielded/unarmored motor cables
in the installation cabinets.

7 RS485 Installation and Set-up
7.1 RS485
7.1.1 Overview
RS485 is a 2-wire bus interface compatible with multi-drop network topology, that is, nodes can be connected as a bus, or via drop cables from a common trunk line. A total of 32 nodes can be connected to 1 network segment. Repeaters divide network segments.
NOTICE
Each repeater functions as a node within the segment in which it is installed. Each node connected within a given network must have a unique node address across all
77
segments.
Terminate each segment at both ends, using either the termination switch (S801) of the frequency converters or a biased termination resistor network. Always use shielded twisted pair (STP) cable for bus cabling, and follow good common installation practice.
Low-impedance ground connection of the shield at every node is important. Connect a large surface of the shield to ground, for example with a cable clamp or a conductive cable gland. Apply potential-equalizing cables to maintain the same ground potential throughout the network ­particularly in installations with long cables. To prevent impedance mismatch, always use the same type of cable throughout the entire network. When connecting a motor to the frequency converter, always use shielded motor cable.
7.1.2 Network Connection
Connect the frequency converter to the RS485 network as follows (see also Illustration 7.1):
1. Connect signal wires to terminal 68 (P+) and terminal 69 (N-) on the main control board of the frequency converter.
2. Connect the cable shield to the cable clamps.
NOTICE
To reduce noise between conductors, use shielded, twisted-pair cables.

7.1.5 EMC Precautions
NOTICE
Observe relevant national and local regulations regarding protective ground connection. Failure to ground the cables properly can result in communication degradation and equipment damage. To avoid coupling of high frequency noise between the cables, keep the RS485 communication cable away from motor and brake resistor cables. Normally, a distance of 200 mm (8 in) is sucient. Maintain the greatest possible distance between the cables, especially where cables run in parallel over long distances. When crossing is unavoidable, the RS485 cable must cross motor and brake resistor cables at an angle of 90°.

7.2 FC Protocol
7.2.1 Overview
The FC protocol, also referred to as FC bus or standard bus, is the Danfoss standard technique according to the master-slave principle for communications via a serial bus. One master and a maximum of 126 slaves can be connected to the bus. The master selects the individual slaves via an address character in the telegram. A slave itself can never transmit without rst being requested to do so, and direct message transfer between the individual slaves is not possible. Communications occur in the half­duplex mode. The master function cannot be transferred to another node (single-master system).

7.4 FC Protocol Message Framing Structure
7.4.1 Content of a Character (Byte)
77
The physical layer is RS485, thus utilizing the RS485 port built into the frequency converter. The FC protocol supports
dierent telegram formats: A short format of 8 bytes for process data.
A long format of 16 bytes that also includes a
parameter channel.
A format used for texts.
Each character transferred begins with a start bit. Then 8 data bits are transferred, corresponding to a byte. Each character is secured via a parity bit. This bit is set at 1 when it reaches parity. Parity is when there is an equal number of 1s in the 8 data bits and the parity bit in total. A stop bit completes a character, thus consisting of 11 bits in all.
7.2.2 FC with Modbus RTU
The FC protocol provides access to the control word and bus reference of the frequency converter.
The control word allows the Modbus master to control several important functions of the frequency converter:
Start.
Stop of the frequency converter in various ways:
- Coast stop.
- Quick stop.
- DC brake stop.
- Normal (ramp) stop.
Reset after a fault trip.
Run at various preset speeds.
Run in reverse.
Change of the active set-up.
Control of the 2 relays built into the frequency
converter.
The bus reference is commonly used for speed control. It is also possible to access the parameters, read their values, and where possible, write values to them. Accessing the parameters oers a range of control options, including controlling the setpoint of the frequency converter when its internal PI controller is used.
Illustration 7.4 Content of a Character
7.4.2 Telegram Structure
Each telegram has the following structure:
Start character (STX) = 02 hex.
A byte denoting the telegram length (LGE).
A byte denoting the frequency converter address
(ADR).
Several data bytes (variable, depending on the type of telegram) follow.
A data control byte (BCC) completes the telegram.

7.4.9 Index (IND)
The index is used with the parameter number to read/ write access parameters with an index, for example, parameter 15-30 Alarm Log: Error Code. The index consists of 2 bytes: a low byte and a high byte.
Only the low byte is used as an index.
7.4.10 Parameter Value (PWE)
The parameter value block consists of 2 words (4 bytes), and the value depends on the dened command (AK). The master prompts for a parameter value when the PWE block contains no value. To change a parameter value (write), write the new value in the PWE block and send from the master to the slave.
When a slave responds to a parameter request (read command), the present parameter value in the PWE block is transferred and returned to the master. If a parameter contains several data options, for example

Parameter 15-40 FC Type to parameter 15-53 Power Card Serial Number contain data type 9.
For example, read the unit size and mains voltage range in parameter 15-40 FC Type. When a text string is transferred (read), the length of the telegram is variable, and the texts are of dierent lengths. The telegram length is dened in the 2nd byte of the telegram (LGE). When using text transfer, the index character indicates whether it is a read or a write command.
To read a text via the PWE block, set the parameter command (AK) to F hex. The index character high-byte must be 4.

7.5.1 Writing a Parameter Value
Change parameter 4-14 Motor Speed High Limit [Hz] to 100 Hz. Write the data in EEPROM.
PKE = E19E hex - Write single word in parameter 4-14 Motor Speed High Limit [Hz]:
IND = 0000 hex.
PWEHIGH = 0000 hex.
PWELOW = 03E8 hex.
Data value 1000, corresponding to 100 Hz, see chapter 7.4.12 Conversion.
7 7
Parameter 4-12 Motor Speed Low Limit [Hz] has a conversion factor of 0.1. To preset the minimum frequency to 10 Hz, transfer the value 100. A conversion factor of 0.1 means that the value transferred is multiplied by 0.1. The value 100 is thus perceived as 10.0.

Modbus RTU Overview
7.6
7.6.1 Introduction
Danfoss assumes that the installed controller supports the interfaces in this document, and strictly observes all requirements and limitations stipulated in the controller and frequency converter.
The built-in Modbus RTU (remote terminal unit) is designed to communicate with any controller that supports the interfaces dened in this document. It is assumed that the user has full knowledge of the capabilities and limitations of the controller.

Regardless of the type of physical communication networks, this section describes the process that a controller uses to request access to another device. This process includes how the Modbus RTU responds to requests from another device, and how errors are detected and reported. It also establishes a common format for the layout and contents of telegram elds.
During communications over a Modbus RTU network, the protocol:
Determines how each controller learns its device
address.
Recognizes a telegram addressed to it.
Determines which actions to take.
Extracts any data or other information contained
in the telegram.
If a reply is required, the controller constructs the reply telegram and sends it. Controllers communicate using a master/slave technique in which only the master can initiate transactions (called queries). Slaves respond by supplying the requested data to the master, or by acting as requested in the query. The master can address individual slaves, or initiate a broadcast telegram to all slaves. Slaves return a response to queries that are addressed to them individually. No responses are returned to broadcast queries from the master.
The Modbus RTU protocol establishes the format for the master query by providing the following information:
The device (or broadcast) address.
A function code dening the requested action.
Any data to be sent.
An error-checking eld.
The response telegram of the slave device is also constructed using Modbus protocol. It contains elds conrming the action taken, any data to be returned, and
88 Danfoss A/S © 04/2018 All rights reserved. MG18C802

an error-checking eld. If an error occurs in receipt of the telegram, or if the slave is unable to perform the requested action, the slave constructs and sends an error message. Alternatively, a timeout occurs.
7.6.3 Frequency Converter with Modbus
RTU
The frequency converter communicates in Modbus RTU format over the built-in RS485 interface. Modbus RTU provides access to the control word and bus reference of the frequency converter.
The control word allows the Modbus master to control several important functions of the frequency converter:
Start.
Various stops:
- Coast stop.
- Quick stop.
- DC brake stop.
- Normal (ramp) stop.
Reset after a fault trip.
Run at various preset speeds.
Run in reverse.
Change the active set-up.
Control built-in relay of the frequency converter.
The bus reference is commonly used for speed control. It is also possible to access the parameters, read their values, and, where possible, write values to them. Accessing the parameters controlling the setpoint of the frequency converter when its internal PI controller is used.

7.8.2 Modbus RTU Telegram Structure
The transmitting device places a Modbus RTU telegram into a frame with a known beginning and ending point. This allows receiving devices to begin at the start of the telegram, read the address portion, determine which device is addressed (or all devices, if the telegram is broadcast), and to recognize when the telegram is completed. Partial telegrams are detected and errors set as a result. Characters for transmission must be in hexadecimal 00–FF format in each eld. The frequency converter continuously monitors the network bus, also during silent intervals. When the rst eld (the address eld) is received, each frequency converter or device decodes it to determine which device is being addressed. Modbus RTU telegrams addressed to 0 are broadcast telegrams. No response is permitted for broadcast telegrams. A typical telegram frame is shown in Table 7.14.

VLT® HVAC Basic Drive FC 101
7.8.3 Start/Stop Field
Telegrams start with a silent period of at least 3.5 character intervals. The silent period is implemented as a multiple of character intervals at the selected network baud rate (shown as Start T1-T2-T3-T4). The rst eld to be transmitted is the device address. Following the last transmitted character, a similar period of at least 3.5 character intervals marks the end of the telegram. A new telegram can begin after this period.
Transmit the entire telegram frame as a continuous stream. If a silent period of more than 1.5 character intervals occurs before completion of the frame, the receiving device
ushes the incomplete telegram and assumes that the next byte is the address eld of a new telegram. Similarly, if a new telegram begins before 3.5 character intervals after a previous telegram, the receiving device
77
considers it a continuation of the previous telegram. This behavior causes a timeout (no response from the slave), since the value in the nal CRC eld is not valid for the combined telegrams.
7.8.4 Address Field
The address eld of a telegram frame contains 8 bits. Valid slave device addresses are in the range of 0–247 decimal. The individual slave devices are assigned addresses in the range of 1–247. 0 is reserved for broadcast mode, which all slaves recognize. A master addresses a slave by placing the slave address in the address eld of the telegram. When the slave sends its response, it places its own address in this address eld to let the master know which slave is responding.
7.8.6 Data Field
The data eld is constructed using sets of 2 hexadecimal digits, in the range of 00–FF hexadecimal. These digits are made up of 1 RTU character. The data eld of telegrams sent from a master to a slave device contains additional information which the slave must use to perform accordingly.
The information can include items such as:
Coil or register addresses.
The quantity of items to be handled.
The count of actual data bytes in the
eld.
7.8.7 CRC Check Field
Telegrams include an error-checking eld, operating based on a cyclic redundancy check (CRC) method. The CRC eld checks the contents of the entire telegram. It is applied regardless of any parity check method used for the individual characters of the telegram. The transmitting device calculates the CRC value and appends the CRC as the last eld in the telegram. The receiving device recalculates a CRC during receipt of the telegram and compares the calculated value to the actual value received in the CRC eld. 2 unequal values result in bus timeout. The error-checking eld contains a 16-bit binary value implemented as 2 8-bit bytes. After the implementation, the low-order byte of the eld is appended rst, followed by the high-order byte. The CRC high-order byte is the last byte sent in the telegram.
7.8.8 Coil Register Addressing
7.8.5 Function Field
The function eld of a telegram frame contains 8 bits. Valid codes are in the range of 1–FF. Function elds are used to send telegrams between master and slave. When a telegram is sent from a master to a slave device, the function code eld tells the slave what kind of action to perform. When the slave responds to the master, it uses the function code eld to indicate either a normal (error­free) response, or that some kind of error occurred (called an exception response).
For a normal response, the slave simply echoes the original function code. For an exception response, the slave returns a code that is equivalent to the original function code with its most places a unique code into the data eld of the response telegram. This code tells the master what kind of error occurred, or the reason for the exception. Also refer to
chapter 7.8.11 Function Codes Supported by Modbus RTU and chapter 7.8.12 Modbus Exception Codes.

signicant bit set to logic 1. In addition, the slave
In Modbus, all data is organized in coils and holding registers. Coils hold a single bit, whereas holding registers hold a 2 byte word (that is 16 bits). All data addresses in Modbus telegrams are referenced to 0. The 1st occurrence of a data item is addressed as item number 0. For example: The coil known as coil 1 in a programmable controller is addressed as coil 0000 in the data address eld of a Modbus telegram. Coil 127 decimal is addressed as coil 007Ehex (126 decimal). Holding register 40001 is addressed as register 0000 in the data address eld of the telegram. The function code eld already species a holding register operation. Therefore, the 4XXXX reference is implicit. Holding register 40108 is addressed as register 006Bhex (107 decimal).

of reference number and transfer length is
invalid. For a controller with 100 registers,
a request with oset 96 and length 4
succeeds, while a request with oset 96
and length 5 generates exception 02.
A value contained in the query data eld
is not an allowable value for server (or
slave). This indicates a fault in the
structure of the remainder of a complex
request, such as that the implied length is
incorrect. It does NOT mean that a data
item submitted for storage in a register
has a value outside the expectation of the
application program, since the Modbus
protocol is unaware of the signicance of
any value of any register.
An unrecoverable error occurred while the
server (or slave) was attempting to
perform the requested action.
7.9.3 IND (Index)
Some parameters in the frequency converter are array parameters, for example parameter 3-10 Preset Reference. Since the Modbus does not support arrays in the holding registers, the frequency converter has reserved the holding register 9 as pointer to the array. Before reading or writing an array parameter, set the holding register 9. Setting holding register to the value of 2 causes all following read/ write to array parameters to be to the index 2.
7.9.4 Text Blocks
Parameters stored as text strings are accessed in the same way as the other parameters. The maximum text block size is 20 characters. If a read request for a parameter is for more characters than the parameter stores, the response is truncated. If the read request for a parameter is for fewer characters than the parameter stores, the response is space
lled.
7.9.5 Conversion Factor
A parameter value can only be transferred as a whole number. To transfer decimals, use a conversion factor.
7.9.6 Parameter Values
7.9.1 Parameter Handling
The PNU (parameter number) is translated from the register address contained in the Modbus read or write message. The parameter number is translated to Modbus as (10 x parameter number) decimal. Example: Reading parameter 3-12 Catch up/slow Down Value (16 bit): The holding register 3120 holds the parameters value. A value of 1352 (decimal) means that the parameter is set to
12.52%.
Reading parameter 3-14 Preset Relative Reference (32 bit): The holding registers 3410 and 3411 hold the parameters values. A value of 11300 (decimal), means that the parameter is set to 1113.00.
For information on the parameters, size, and conversion index, see chapter 6 Programming.
Standard data types
Standard data types are int 16, int 32, uint 8, uint 16, and uint 32. They are stored as 4x registers (40001–4FFFF). The parameters are read using function 03 hex read holding registers. Parameters are written using the function 6 hex preset single register for 1 register (16 bits), and the function 10 hex preset multiple registers for 2 registers (32 bits). Readable sizes range from 1 register (16 bits) up to 10 registers (20 characters).
Non-standard data types
Non-standard data types are text strings and are stored as 4x registers (40001–4FFFF). The parameters are read using function 03 hex read holding registers and written using function 10 hex preset multiple registers. Readable sizes range from 1 register (2 characters) up to 10 registers (20 characters).
Examples
7.10
7.9.2 Storage of Data
The coil 65 decimal determines whether data written to the frequency converter is stored in EEPROM and RAM (coil 65 = 1), or only in RAM (coil 65 = 0).

Bit 02, DC brake
Bit 02 = 0: Leads to DC braking and stop. Set braking current and duration in parameter 2-01 DC Brake Current and parameter 2-02 DC Braking Time. Bit 02 = 1: Leads to ramping.
Bit 03, Coasting
Bit 03 = 0: The frequency converter immediately releases the motor (the output transistors are shut o), and it coasts to a standstill. Bit 03 = 1: If the other starting conditions are met, the frequency converter starts the motor.
In parameter 8-50 Coasting Select, dene how bit 03 gates with the corresponding function on a digital input.
Bit 04, Quick stop
Bit 04 = 0: Makes the motor speed ramp down to stop (set in parameter 3-81 Quick Stop Ramp Time).
Bit 05, Hold output frequency
Bit 05 = 0: The present output frequency (in Hz) freezes. Change the frozen output frequency only with the digital inputs programmed to [21] Speed up and [22] Speed down (parameter 5-10 Terminal 18 Digital Input to parameter 5-13 Terminal 29 Digital Input).
NOTICE
If freeze output is active, the frequency converter can only be stopped in 1 of the following ways:
Bit 03 coast stop.
Bit 02 DC brake.
Digital input programmed to [5] DC brake
inverse, [2] Coast inverse, or [3] Coast and reset inv (parameter 5-10 Terminal 18 Digital Input to parameter 5-13 Terminal 29 Digital Input).
Bit 06, Ramp stop/start
Bit 06 = 0: Causes a stop and makes the motor speed ramp down to stop via the selected ramp-down parameter. Bit 06 = 1: If the other starting conditions are met, bit 06 allows the frequency converter to start the motor.
In parameter 8-53 Start Select, dene how bit 06 ramp stop/ start gates with the corresponding function on a digital input.
Bit 07, Reset
Bit 07 = 0: No reset. Bit 07 = 1: Resets a trip. Reset is activated on the leading signal edge, that is, when changing from logic 0 to logic 1.
Bit 08, Jog
Bit 08 = 1: Parameter 3-11 Jog Speed [Hz] determines the output frequency.
Bit 09, Selection of ramp 1/2
Bit 09 = 0: Ramp 1 is active (parameter 3-41 Ramp 1 Ramp Up Time to parameter 3-42 Ramp 1 Ramp Down Time).
Bit 09 = 1: Ramp 2 (parameter 3-51 Ramp 2 Ramp Up Time to parameter 3-52 Ramp 2 Ramp Down Time) is active.
