Approvals and Certications

1.4

Drives are designed in compliance with the directives described in this section.

1.4.1 CE Mark

The CE mark (Conformité Européenne) indicates that the product manufacturer conforms to all applicable EU directives.

The EU directives applicable to the design and manufacture of drives are:

The Low Voltage Directive.

•

The EMC Directive.

•

The Machinery Directive (for units with an

•

integrated safety function).

The CE mark is intended to eliminate technical barriers to free trade between the EC and EFTA states inside the ECU. The CE mark does not regulate the quality of the product. Technical specications cannot be deduced from the CE mark.

1.4.2 Low Voltage Directive

Drives are classied as electronic components and must be CE-labeled in accordance with the Low Voltage Directive. The directive applies to all electrical equipment in the 50– 1000 V AC and the 75–1500 V DC voltage ranges.

The directive mandates that the equipment design must ensure the safety and health of people and livestock, and the preservation of material by ensuring the equipment is properly installed, maintained, and used as intended. Danfoss CE labels comply with the Low Voltage Directive, and Danfoss provides a declaration of conformity upon request.

Introduction Design Guide

1.4.3 EMC Directive

Electromagnetic compatibility (EMC) means that electromagnetic interference between pieces of equipment does not hinder their performance. The basic protection requirement of the EMC Directive 2014/30/EU states that devices that generate electromagnetic interference (EMI) or whose operation could be aected by EMI must be designed to limit the generation of electromagnetic interference and shall have a suitable degree of immunity to EMI when properly installed, maintained, and used as intended.

A drive can be used as stand-alone device or as part of a more complex installation. Devices in either of these cases must bear the CE mark. Systems must not be CE-marked but must comply with the basic protection requirements of the EMC directive.

3.2 Automated Operational Features

Automated operational features are active when the drive is operating. Most of them require no programming or setup. The drive has a range of built-in protection functions to protect itself and the motor when it runs.

For details of any set-up required, in particular motor parameters, refer to the programming guide.

3.2.1 Short-circuit Protection

The overvoltage can be handled either using a brake function (parameter 2-10 Brake Function) and/or using overvoltage control (parameter 2-17 Over-voltage Control).

Brake functions

AC brake is an alternative to improving braking without using a brake resistor. This function controls an overmagnetization of the motor when the motor is acting as a generator. Increasing the electrical losses in the motor allows the OVC function to increase the braking torque without exceeding the overvoltage limit.

NOTICE

Motor (phase-to-phase)

The drive is protected against short circuits on the motor side by current measurement in each of the 3 motor phases. A short circuit between 2 output phases causes an overcurrent in the inverter. The inverter is turned o when the short circuit current exceeds the allowed value (Alarm 16, Trip Lock).

Mains side

A drive that works correctly limits the current it can draw from the supply. Still, it is recommended to use fuses and/or circuit breakers on the supply side as protection if there is component break-down inside the drive (1st fault).

NOTICE

To ensure compliance with IEC 60364 for CE, it is mandatory to use fuses and/or circuit breakers.

AC brake is not as eective as dynamic braking with a resistor.

Overvoltage control (OVC)

By automatically extending the ramp-down time, OVC reduces the risk of the drive tripping due to an overvoltage on the DC link.

NOTICE

OVC can be activated for a PM motor.

NOTICE

Do not enable OVC in hoisting applications.

3.2.3 Missing Motor Phase Detection

3.2.2 Overvoltage Protection

Motor-generated overvoltage

The voltage in the DC link is increased when the motor acts as a generator. This situation occurs in the following cases:

The load rotates the motor at constant output

•

frequency from the drive, 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 throughout the drive system.

Incorrect slip compensation setting causing

•

higher DC-link voltage.

Back EMF from PM motor operation. If coasted at

•

high RPM, the PM motor back EMF can potentially exceed the maximum voltage tolerance of the drive and cause damage. To help prevent this situation, the value of parameter 4-19 Max Output Frequency is automatically limited based on an internal calculation based on the value of parameter 1-40 Back EMF at 1000 RPM, parameter 1-25 Motor Nominal Speed, and parameter 1-39 Motor Poles.

The missing motor phase function (parameter 4-58 Missing Motor Phase Function) is enabled by default to avoid motor damage if a motor phase is missing. The default setting is 1000 ms, but it can be adjusted for faster detection.

3.2.4 Supply Voltage Imbalance Detection

Operation under severe supply voltage imbalance reduces the lifetime of the motor and drive. If the motor is operated continuously near nominal load, conditions are considered severe. The default setting trips the drive if there is supply voltage imbalance (parameter 14-12 Response to Mains Imbalance).

3.2.5 Switching on the Output

Adding a switch to the output between the motor and the drive is allowed, however fault messages can appear.

Product Overview and Featur... Design Guide

3.2.6 Overload Protection

Torque limit

The torque limit feature protects the motor against overload, independent of the speed. Torque limit is controlled in parameter 4-16 Torque Limit Motor Mode and parameter 4-17 Torque Limit Generator Mode. The time before the torque limit warning trips is controlled in parameter 14-25 Trip Delay at Torque Limit.

Current limit

The current limit is controlled in parameter 4-18 Current Limit, and the time before the drive trips is controlled in parameter 14-24 Trip Delay at Current Limit.

Speed limit

Minimum speed limit: Parameter 4-11 Motor Speed Low Limit [RPM] or parameter 4-12 Motor Speed Low Limit [Hz]

limit the minimum operating speed range of the drive. Maximum speed limit: Parameter 4-13 Motor Speed High Limit [RPM] or parameter 4-19 Max Output Frequency limits the maximum output speed that the drive can provide.

Electronic thermal relay (ETR)

ETR is an electronic feature that simulates a bimetal relay based on internal measurements. The characteristic is shown in Illustration 3.1.

Voltage limit

The inverter turns link capacitors when a certain hard-coded voltage level is reached.

Overtemperature

The drive has built-in temperature sensors and reacts immediately to critical values via hard-coded limits.

o to protect the transistors and the DC

3.2.7 Locked Rotor Protection

There can be situations when the rotor is locked due to excessive load or other factors. The locked rotor cannot produce enough cooling, which in turn can overheat the motor winding. The drive is able to detect the locked rotor situation with PM VVC+ control (parameter 30-22 Locked Rotor Protection).

3.2.8 Automatic Derating

The drive constantly checks for the following critical levels:

High temperature on the control card or heat

•

sink.

High motor load.

•

High DC-link voltage.

•

Low motor speed.

•

As a response to a critical level, the drive adjusts the switching frequency. For high internal temperatures and low motor speed, the drive can also force the PWM pattern to SFAVM.

NOTICE

The automatic derating is dierent when

parameter 14-55 Output Filter is set to [2] Sine-Wave Filter Fixed.

3.2.9 Automatic Energy Optimization

Automatic energy optimization (AEO) directs the drive to monitor the load on the motor continuously and adjust the output voltage to maximize eciency. Under light load, the voltage is reduced and the motor current is minimized. The motor benets from:

Increased eciency.

•

Reduced heating.

•

Quieter operation.

•

There is no need to select a V/Hz curve because the drive automatically adjusts motor voltage.

3.2.10 Automatic Switching Frequency Modulation

The drive generates short electrical pulses to form an AC wave pattern. The switching frequency is the rate of these pulses. A low switching frequency (slow pulsing rate) causes audible noise in the motor, making a higher switching frequency preferable. A high switching frequency, however, generates heat in the drive that can limit the amount of current available to the motor.

Automatic switching frequency modulation regulates these conditions automatically to provide the highest switching frequency without overheating the drive. By providing a regulated high switching frequency, it quiets motor operating noise at slow speeds, when audible noise control is critical, and produces full output power to the motor when required.

3.2.11 Automatic Derating for High Switching Frequency

The drive is designed for continuous, full-load operation at switching frequencies between 1.5–2 kHz for 380–480 V. The frequency range depends on power size and voltage rating. A switching frequency exceeding the maximum allowed range generates increased heat in the drive and requires the output current to be derated.

An automatic feature of the drive is load-dependent switching frequency control. This feature allows the motor to benet from as high a switching frequency as the load allows.

3.2.12 Power Fluctuation Performance

The drive withstands mains uctuations such as:

Transients.

•

Momentary drop-outs.

•

The drive automatically compensates for input voltages ±10% from the nominal to provide full rated motor voltage and torque. With auto restart selected, the drive automatically powers up after a voltage trip. With ying start, the drive synchronizes to motor rotation before start.

Short voltage drops.

•

Surges.

•

3.2.13 Resonance Damping

Resonance damping eliminates the high-frequency motor resonance noise. Automatic or manually selected frequency damping is available.

3.2.14 Temperature-controlled Fans

Sensors in the drive regulate the operation of the internal cooling fans. Often, the cooling fans do not run during low load operation, or when in sleep mode or standby. These sensors reduce noise, increase eciency, and extend the operating life of the fan.

3.2.15 EMC Compliance

Electromagnetic interference (EMI) and radio frequency interference (RFI) are disturbances that can aect an electrical circuit due to electromagnetic induction or radiation from an external source. The drive is designed to comply with the EMC product standard for drives IEC 61800-3 and the European standard EN 55011. Motor cables must be shielded and properly terminated to comply with the emission levels in EN 55011. For more information regarding EMC performance, see chapter 7.13.1 EMC Test Results.

The components that make up the galvanic isolation are:

Supply, including signal isolation.

•

Gatedrive for the IGBTs, trigger transformers, and

•

optocouplers.

The output current Hall eect transducers.

•

3.3 Custom Application Features

Custom application functions are the most common features programmed in the drive for enhanced system performance. They require minimum programming or setup. See the programming guide for instructions on activating these functions.

3.3.1 Automatic Motor Adaptation

Automatic motor adaptation (AMA) is an automated test procedure used to measure the electrical characteristics of the motor. AMA provides an accurate electronic model of the motor, allowing the drive to calculate optimal performance and eciency. Running the AMA procedure also maximizes the automatic energy optimization feature of the drive. AMA is performed without the motor rotating and without uncoupling the load from the motor.

3.3.2 Built-in PID Controller

The built-in proportional, integral, derivative (PID) controller eliminates the need for auxiliary control devices. The PID controller maintains constant control of closedloop systems where regulated pressure, ow, temperature, or other system requirements must be maintained.

The drive can use 2 feedback signals from 2 dierent devices, allowing the system to be regulated with dierent feedback requirements. The drive makes control decisions by comparing the 2 signals to optimize system performance.

3.3.3 Motor Thermal Protection

3.2.16 Galvanic Isolation of Control Terminals

All control terminals and output relay terminals are galvanically isolated from mains power, which completely protects the controller circuitry from the input current. The output relay terminals require their own grounding. This isolation meets the stringent protective extra-low voltage (PELV) requirements for isolation.

To protect the application from serious damage, the drive oers several dedicated features.

Torque limit

The torque limit protects the motor from being overloaded independent of the speed. Torque limit is controlled in

parameter 4-16 Torque Limit Motor Mode and parameter 4-17 Torque Limit Generator Mode. Parameter 14-25 Trip Delay at Torque Limit controls the time

before the torque limit warning trips.

Current limit

Parameter 4-18 Current Limit controls the current limit, and parameter 14-24 Trip Delay at Current Limit controls the

time before the current limit warning trips.

Parameter 4-12 Motor Speed Low Limit [Hz] sets the minimum output speed that the drive can provide.

Maximum speed limit

Parameter 4-14 Motor Speed High Limit [Hz] or parameter 4-19 Max Output Frequency sets the maximum

output speed that the drive can provide.

ETR (electronic thermal relay)

The drive ETR function measures the actual current, speed, and time to calculate motor temperature. The function also protects the motor from being overheated (warning or trip). An external thermistor input is also available. ETR is an electronic feature that simulates a bimetal relay based on internal measurements. The characteristic is shown in Illustration 3.1.

The drive can be congured (parameter 14-10 Mains Failure) to dierent types of behavior during mains drop-out:

Trip lock once the DC-link is exhausted.

•

Coast with ying start whenever mains return

•

(parameter 1-73 Flying Start).

Kinetic back-up.

•

Controlled ramp down.

•

Flying start

This selection makes it possible to catch a motor that is spinning freely due to a mains drop-out. This option is relevant for centrifuges and fans.

Kinetic back-up

This selection ensures that the drive runs as long as there is energy in the system. For short mains drop-out, the operation is restored after mains return, without bringing the application to a stop or losing control at any time. Several variants of kinetic back-up can be selected.

Congure the behavior of the drive at mains drop-out in

parameter 14-10 Mains Failure and parameter 1-73 Flying Start.

3.3.5 Automatic Restart

3 3

The drive can be programmed to restart the motor automatically after a minor trip, such as momentary power loss or uctuation. This feature eliminates the need for manual resetting and enhances automated operation for remotely controlled systems. The number of restart

nominal. The Y-axis shows the time in seconds before the ETR cuts o and trips the drive. The curves show the characteristic nominal speed at twice the nominal speed and at 0.2 x the nominal speed. 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. The calculated temperature is visible as a

The drive follows a variable V/Hz curve to provide full motor torque even at reduced speeds. Full output torque can coincide with the maximum designed operating speed of the motor. This drive diers from variable torque drives and constant torque drives. Variable torque drives provide reduced motor torque at low speed. Constant torque drives provide excess voltage, heat, and motor noise at less than full speed.

readout parameter in parameter 16-18 Motor Thermal.

3.3.7 Frequency Bypass

3.3.4 Mains Drop-out

During a mains drop-out, the drive keeps running until the DC-link voltage drops below the minimum stop level. The minimum stop level is typically 15% below the lowest rated supply voltage. The mains voltage before the dropout and the motor load determine how long it takes for the drive to coast.

In some applications, the system can have operational speeds that create a mechanical resonance. This mechanical resonance can generate excessive noise and possibly damage mechanical components in the system. The drive has 4 programmable bypass-frequency bandwidths. The bandwidths allow the motor to step over speeds that induce system resonance.

3.3.8 Motor Preheat

To preheat a motor in a cold or damp environment, a small amount of DC current can be trickled continuously into the motor to protect it from condensation and cold starts. This function can eliminate the need for a space heater.

3.3.9 Programmable Set-ups

The drive has 4 set-ups that can be independently programmed. Using multi-setup, it is possible to switch between independently programmed functions activated by digital inputs or a serial command. Independent set-ups are used, for example, to change references, or for day/ night or summer/winter operation, or to control multiple motors. The LCP shows the active set-up.

Set-up data can be copied from drive to drive by downloading the information from the removable LCP.

3.3.10 Smart Logic Control (SLC)

Smart logic control (SLC) is a sequence of user-dened actions (see parameter 13-52 SL Controller Action [x]) executed by the SLC when the associated user-dened event (see parameter 13-51 SL Controller Event [x]) is evaluated as TRUE by the SLC. The condition for an event can be a particular status, or that the output from a logic rule or a comparator operand becomes TRUE. The condition leads to an associated action as shown in Illustration 3.2.

Illustration 3.2 SLC Event and Action

Events and actions are each numbered and linked in pairs (states), which means that when event [0] is fullled (attains the value TRUE), action [0] is executed. After the 1 action is executed, the conditions of the next event are evaluated. If this event is evaluated as true, then the corresponding action is executed. Only 1 event is evaluated at any time. If an event is evaluated as false, nothing happens in the SLC during the current scan interval and no other events are evaluated. When the SLC starts, it only evaluates event [0] during each scan interval. Only when event [0] is evaluated as true, the SLC executes action [0] and starts evaluating the next event. It is possible to program 1–20 events and actions. When the last event/action has been executed, the sequence starts over again from event [0]/action [0]. Illustration 3.3 shows an example with 4 event/actions:

Comparators are used for comparing continuous variables (output frequency, output current, analog input, and so on) to xed preset values.

3.4 Dynamic Braking Overview

Dynamic braking slows the motor using 1 of the following methods:

AC brake

•

The brake energy is distributed in the motor by changing the loss conditions in the motor (parameter 2-10 Brake Function = [2]). The AC brake function cannot be used in applications with high cycling frequency since this situation overheats the motor.

DC brake

•

An overmodulated DC current added to the AC current works as an eddy current brake (parameter 2-02 DC Braking Time ≠ 0 s).

3.5 Back-channel Cooling Overview

A unique back-channel duct passes cooling air over the heat sinks with minimal air passing through the electronics area.

There is an IP54/Type 12 seal between the back-channel cooling duct and the electronics area of the VLT® drive. This backchannel cooling allows 90% of the heat losses to be exhausted directly outside the enclosure. This design improves reliability and prolongs component life by dramatically reducing interior temperatures and contamination of the electronic

components. Dierent back-channel cooling kits are available to redirect the airow based on individual needs.
