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
55
parameters, refer to the programming guide.
5.1.1 Short-circuit Protection
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 (Alarm16, 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).
Mains side fuses are mandatory for UL compliance.
NOTICE
To ensure compliance with IEC 60364 for CE or NEC 2009
for UL, it is mandatory to use fuses and/or circuit
breakers.
Brake resistor
The drive is protected from a short circuit in the brake
resistor.
Load sharing
To protect the DC bus against short circuits and the drives
from overload, install DC fuses in series with the load
sharing terminals of all connected units.
5.1.2 Overvoltage Protection
•
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 at1000 RPM, parameter 1-25 Motor Nominal Speed,
and parameter 1-39 Motor Poles.
NOTICE
To avoid motor overspeeds (for example, due to
excessive windmilling eects), equip the drive with a
brake resistor.
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
Connect a brake resistor for dissipation of surplus brake
energy. Connecting a brake resistor allows a higher DC-link
voltage during braking.
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
AC brake is not as eective 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.
Motor-generated overvoltage
The voltage in the DC link is increased when the motor
acts as a generator. This situation occurs in 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.
OVC can be activated for a PM motor with all control
core, PM VVC+, Flux OL, and Flux CL for PM Motors.
NOTICE
Do not enable OVC in hoisting applications.
Product FeaturesDesign Guide
5.1.3 Missing Motor Phase Detection
The missing motor phase function (parameter 4-58 MissingMotor 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.
5.1.4 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 Function at Mains Imbalance).
5.1.5 Switching on the Output
Adding a switch to the output between the motor and the
drive is allowed, however fault messages can appear.
Danfoss does not recommend using this feature for 525–
690 V drives connected to an IT mains network.
5.1.6 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 andparameter 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 HighLimit [RPM] or parameter 4-19 Max Output Frequency limit
the maximum output speed 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 5.1.
Voltage limit
The inverter turns o to protect the transistors and the DC
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.
5.1.7 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 open-loop PM ux control and PM VVC
control (parameter 30-22 Locked Rotor Protection).
+
5.1.8 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 drives can also force the PWM
pattern to SFAVM.
NOTICE
The automatic derating is dierent when
parameter 14-55 Output Filter is set to [2] Sine-Wave Filter
Fixed.
5.1.9 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 eciency. Under light
load, the voltage is reduced and the motor current is
minimized. The motor benets from:
Increased eciency.
•
Reduced heating.
•
Quieter operation.
•
There is no need to select a V/Hz curve because the drive
automatically adjusts motor voltage.
5.1.10 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.
5.1.11 Automatic Derating for High
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 10.15.1 EMC Test Results.
Switching Frequency
5.1.16 Galvanic Isolation of Control
The drive is designed for continuous, full-load operation at
switching frequencies between 1.5–2 kHz for 380–500 V,
55
and 1–1.5 kHz for 525–690 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 benet from as high a switching frequency as the load
allows.
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.
The components that make up the galvanic isolation
are:
5.1.12 Power Fluctuation Performance
The drive withstands mains uctuations such as:
Transients.
•
Momentary drop-outs.
•
Short voltage drops.
•
Surges.
•
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.
5.1.13 Resonance Damping
Resonance damping eliminates the high-frequency motor
resonance noise. Automatic or manually selected frequency
damping is available.

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.
5.2.1 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 eciency. 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.

5.2.2 Built-in PID Controller
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 eciency, and extend the
operating life of the fan.
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,

A special version of the ETR is also available for EX-e
motors in ATEX areas. This function makes it possible to
enter a specic curve to protect the Ex-e motor. See the
programming guide for set-up instructions.
5.2.4 Motor Thermal Protection for Ex-e
Motors
The drive is equipped with an ATEX ETR thermal
®
monitoring function for operation of Ex-e motors according
to EN-60079-7. When combined with an ATEX approved
PTC monitoring device such as the VLT® PTC Thermistor
Card MCB 112 option or an external device, the installation
does not require an individual approval from an
approbated organization.
The ATEX ETR thermal monitoring function enables use of
an Ex-e motor instead of a more expensive, larger, and
heavier Ex-d motor. The function ensures that the drive
limits motor current to prevent overheating.
Requirements related to the Ex-e motor
Ensure that the Ex-e motor is approved for
•
operation in hazardous zones (ATEX zone 1/21,
ATEX zone 2/22) with drives. The motor must be
certied for the specic hazardous zone.
Install the Ex-e motor in zone 1/21 or 2/22 of the
•
hazardous zone, according to motor approval.

5.2.5 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 determines how long it takes for
the drive to coast.
The drive can be congured (parameter 14-10 Mains Failure)
to dierent types of behavior during mains drop-out:

5.2.6 Automatic Restart
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
attempts and the duration between attempts can be
limited.
5.2.7 Full Torque at Reduced Speed
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 diers 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.
Set-up data can be copied from drive to drive by
downloading the information from the removable LCP.
5.2.11 Smart Logic Control (SLC)
Smart logic control (SLC) is a sequence of user-dened
actions (see parameter 13-52 SL Controller Action [x])
executed by the SLC when the associated user-dened
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 5.3.
55
5.2.8 Frequency Bypass
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.
5.2.9 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.
5.2.10 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.
Illustration 5.3 SLC Event and Action
Events and actions are each numbered and linked in pairs
(states), which means that when event [0] is fullled
(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].

5.3 Dynamic Braking Overview
Dynamic braking slows the motor using 1 of the following
methods:
Comparators
Comparators are used for comparing continuous variables
(output frequency, output current, analog input, and so on)
to xed preset values.
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).

information on selecting a brake resistor, see VLTBrake Resistor MCE 101 Design Guide.
®
For drives equipped with the brake option, a brake IGBT
along with terminals 81(R-) and 82(R+) are included for
connecting an external brake resistor.
The function of the brake IGBT is to limit the voltage in the
DC link whenever the maximum voltage limit is exceeded.
It limits the voltage by switching the externally mounted
resistor across the DC bus to remove excess DC voltage

protecting the drive from overheating if the brake resistor
is overloaded.
The brake IGBT gate signal originates on the control card
and is delivered to the brake IGBT via the power card and
gatedrive card. Also, the power and control cards monitor
the brake IGBT for a short circuit. The power card also
monitors the brake resistor for overloads.
Product FeaturesDesign Guide
5.4 Mechanical Holding Brake Overview
A mechanical holding brake is an external piece of equipment mounted directly on the motor shaft that performs static
braking. Static braking is when a brake is used to clamp down on the motor after the load has been stopped. A holding
brake is either controlled by a PLC or directly by a digital output from the drive.
NOTICE
A drive cannot provide a safe control of a mechanical brake. A redundancy circuitry for the brake control must be
included in the installation.
5.4.1 Mechanical Brake Using Open-loop Control
For hoisting applications, typically it is necessary to control an electromagnetic brake. A relay output (relay 1 or relay 2) or a
programmed digital output (terminal 27 or 29) is required. Normally, this output must be closed for as long as the drive is
unable to hold the motor. In parameter 5-40 Function Relay (array parameter), parameter 5-30 Terminal 27 Digital Output, or
parameter 5-31 Terminal 29 Digital Output, select [32] mechanical brake control for applications with an electromagnetic brake.
When [32] mechanical brake control is selected, the mechanical brake relay remains closed during start until the output
current is above the level selected in parameter 2-20 Release Brake Current. During stop, the mechanical brake closes when
the speed is below the level selected in parameter 2-21 Activate Brake Speed [RPM]. If the drive is brought into an alarm
condition, such as an overvoltage situation, the mechanical brake immediately cuts in. The mechanical brake also cuts in
during safe torque o.
Consider the following when using the electromagnetic brake:
Use any relay output or digital output (terminal 27 or 29). If necessary, use a contactor.
•
Ensure that the output is switched
•
being too heavy or the motor not being mounted.
Before connecting the mechanical brake, select [32] Mechanical brake control in parameter group 5-4* Relays (or in
•
parameter group5-3* Digital Outputs).

•
The brake is engaged when the output frequency is less than the frequency set in parameter 2-21 Activate Brake

o as long as the drive is unable to rotate the motor. Examples include the load
55
NOTICE
For vertical lifting or hoisting applications, ensure that the load can be stopped if there is an emergency or a
malfunction. If the drive is in alarm mode or in an overvoltage situation, the mechanical brake cuts in.
For hoisting applications, make sure that the torque limits in parameter 4-16 Torque Limit Motor Mode and
parameter 4-17 Torque Limit Generator Mode are set lower than the current limit in parameter 4-18 Current Limit. It is alsorecommended to set parameter 14-25 Trip Delay at Torque Limit to 0, parameter 14-26 Trip Delay at Inverter Fault to 0, and
parameter 14-10 Mains Failure to [3] Coasting.
Illustration 5.7 Mechanical Brake Control in Open Loop
5.4.2 Mechanical Brake Using Closed-loop Control
The VLT® AutomationDrive FC 302 features a mechanical brake control designed for hoisting applications and supports the
following functions:
2 channels for mechanical brake feedback, oering protection against unintended behavior resulting from a broken
•
cable.
Monitoring the mechanical brake feedback throughout the complete cycle. Monitoring helps protect the
•
mechanical brake - especially if more drives are connected to the same shaft.
No ramp up until feedback conrms that the mechanical brake is open.
•
Improved load control at stop.
•
The transition when motor takes over the load from the brake can be congured.
•
Parameter 1-72 Start Function[6] Hoist Mech. Brake Rel activates the hoist mechanical brake. The main dierence compared to
the regular mechanical brake control is that the hoist mechanical brake function has direct control over the brake relay.
Instead of setting a current to release the brake, the torque applied against the closed brake before release is dened.
Because the torque is dened directly, the set-up is more straightforward for hoisting applications.
The hoist mechanical brake strategy is based on the following 3-step sequence, where motor control and brake release are
synchronized to obtain the smoothest possible brake release.
1.Pre-magnetize the motor.
To ensure that there is a hold on the motor and to verify that it is mounted correctly, the motor is
magnetized.

Product FeaturesDesign Guide
When the load is held by the mechanical brake, its size cannot be determined, only its direction. The moment the
brake opens, the motor must take over the load. To facilitate the takeover, a user-dened torque
(parameter 2-26 Torque Ref) is applied in the hoisting direction. This process is used to initialize the speed controller
that nally takes over the load. To reduce wear on the gearbox due to backlash, the torque is ramped up.
3.Release the brake.
When the torque reaches the value set in parameter 2-26 Torque Ref, the brake is released. The value set in
parameter 2-25 Brake Release Time determines the delay before the load is released. To react as quickly as possible
on the load-step that follows after brake release, the speed-PID control can be boosted by increasing the proportional gain.

5.5 Load Share Overview
Load share is a feature that allows the connection of DC circuits of several drives, creating a multiple-drive system to run 1
mechanical load. Load share provides the following benets:
Energy savings
A motor running in regenerative mode can supply drives that are running in motoring mode.
Reduced need for spare parts
Usually, only 1 brake resistor is needed for the entire drive system instead of 1 brake resistor for per drive.
Power back-up
If there is mains failure, all linked drives can be supplied through the DC link from a back-up. The application can continue
55
running or go though a controlled shutdown process.
Preconditions
The following preconditions must be met before load sharing is considered:
The drive must be equipped with load sharing terminals.
•
Product series must be the same. Only VLT® AutomationDrive FC 302 drives used with other VLT® AutomationDrive
•
FC 302 drives.
Drives must be placed physically close to one another to allow the wiring between them to be no longer than
•
25 m (82 ft).
Drives must have the same voltage rating.
•
When adding a brake resistor in a load sharing conguration, all drives must be equipped with a brake chopper.
•
Fuses must be added to load share terminals.
•
For a diagram of a load share application in which best practices are applied, see Illustration 5.9.
Illustration 5.9 Diagram of a Load Share Application Where Best Practices are Applied
Units with the built-in load sharing option contain terminals (+) 89 DC and (–) 88 DC. Within the drive, these terminals
connect to the DC bus in front of the DC-link reactor and bus capacitors.
The load sharing terminals can connect in 2 dierentcongurations.
Terminals tie the DC-bus circuits of multiple drives together. This conguration allows a unit that is in a
•
regenerative mode to share its excess bus voltage with another unit that is running a motor. Load sharing in this
manner can reduce the need for external dynamic brake resistors, while also saving energy. The number of units
that can be connected in this way is innite, as long as each unit has the same voltage rating. In addition,
depending on the size and number of units, it may be necessary to install DC reactors and DC fuses in the DC-link
connections, and AC reactors on the mains. Attempting such a conguration requires specic considerations.
The drive is powered exclusively from a DC source. This conguration requires:
•
-A DC source.
-A means to soft charge the DC bus at power-up.
5.6 Regen Overview
Regen typically occurs in applications with continuous braking such as cranes/hoists, downhill conveyors, and centrifuges
where energy is pulled out of a decelerated motor.
55
The excess energy is removed from the drive using 1 of the following options:
Brake chopper allows the excess energy to be dissipated in the form of heat within the brake resistor coils.
•
Regen terminals allow a third-party regen unit to be connected to the drive, allowing the excess energy to be
•
returned to the power grid.
Returning excess energy back to the power grid is the most ecient use of regenerated energy in applications using
continuous braking.

The MCO 350 option for VLT® AutomationDrive FC 302
expands the functional properties of the AC drive in
synchronizing applications and replaces traditional
mechanical solutions.
In applications where the motor is used as a brake, energy
is generated in the motor and sent back into the drive. If
the energy cannot be transported back to the motor, it
increases the voltage in the drive DC line. In applications
with frequent braking and/or high inertia loads, this
increase can lead to an overvoltage trip in the drive and,
nally, a shutdown. Brake resistors are used to dissipate
the excess energy resulting from the regenerative braking.
The resistor is selected based on its ohmic value, its power
dissipation rate, and its physical size. Danfoss oers a wide
variety of dierent resistors that are specially designed to
Danfoss drives. For ordering numbers and more
information on how to dimension brake resistors, refer to
the VLT® Brake Resistor MCE 101 Design Guide.

6.5 Sine-wave Filters
When a drive controls a motor, resonance noise is heard
from the motor. This noise, which is the result of the motor
design, occurs every time an inverter switch in the drive is
activated. The frequency of the resonance noise thus
corresponds to the switching frequency of the drive.
Danfoss supplies a sine-wave
motor noise. The lter reduces the ramp-up time of the
voltage, the peak load voltage (U
current (ΔI) to the motor, which means that current and
voltage become almost sinusoidal. The acoustic motor
noise is reduced to a minimum.
The ripple current in the sine-wave
some noise. Solve the problem by integrating the lter in a
cabinet or enclosure.
For ordering numbers and more information on sine-wave
lters, refer to the Output Filters Design Guide.

), and the ripple
PEAK
lter coils also causes
6.6 dU/dt Filters
Danfoss supplies dU/dt lters which are dierential mode,
low-pass lters that reduce motor terminal phase-to-phase
peak voltages and reduce the rise time to a level that
lowers the stress on the insulation at the motor windings.
This is a typical issue with set-ups using short motor
cables.
Compared to sine-wave lters, the dU/dt lters have a cut-o frequency above the switching frequency.
For ordering numbers and more information on dU/dt
lters, refer to the Output Filters Design Guide.
Common-mode Filters
6.7
High-frequency common-mode cores (HF-CM cores) reduce
electromagnetic interference and eliminate bearing
damage by electrical discharge. They are special nanocrystalline magnetic cores that have superior ltering
performance compared to regular ferrite cores. The HF-CM
core acts like a common-mode inductor between phases
and ground.
Installed around the 3 motor phases (U, V, W), the
common mode lters reduce high-frequency commonmode currents. As a result, high-frequency electromagnetic
interference from the motor cable is reduced.
For ordering numbers refer to the Output Filters DesignGuide.
Harmonic Filters
6.8
The VLT® Advanced Harmonic Filters AHF 005 & AHF 010
should not be compared with traditional harmonic trap
lters. The Danfoss harmonic lters have been specially
designed to match the Danfoss drives.
By connecting the AHF 005 or AHF 010 in front of a
Danfoss drive, the total harmonic current distortion
generated back to the mains is reduced to 5% and 10%.
For ordering numbers and more information on how to
dimension brake resistors, refer to the VLT® Advanced
Harmonic Filters AHF 005/AHF 010 Design Guide.
6.9 Enclosure Built-in Options
The following built-in options are specied in the type
code when ordering the drive.
Enclosure with corrosion-resistant back channel
For extra protection from corrosion in harsh environments,
units can be ordered in an enclosure that includes a
stainless steel back channel, heavier plated heat sinks, and
an upgraded fan. This option is recommended in salt-air
environments, such as those near the ocean.
Mains shielding
Lexan® shielding can be mounted in front of incoming
power terminals and input plate to protect against physical
contact when the enclosure door is open.
Space heaters and thermostat
Mounted in the cabinet interior of enclosure size F drives
and controlled via an automatic thermostat, space heaters
controlled via an automatic thermostat prevent condensation inside the enclosure.
The thermostat default settings turn on the heaters at
10 °C (50 °F) and turn them o at 15.6 °C (60 °F).
Cabinet light with power outlet
To increase visibility during servicing and maintenance, a
light can be mounted on the cabinet interior of enclosure
F drives. The light housing includes a power outlet for
temporarily powering laptop computers or other devices.
Available in 2 voltages:
230 V, 50 Hz, 2.5 A, CE/ENEC
•
120 V, 60 Hz, 5 A, UL/cUL
•
RFI lters
VLT® drive series feature integrated Class A2 RFI lters as
standard. If extra levels of RFI/EMC protection are required,
they can be obtained using optional Class A1 RFI lters,
which provide suppression of radio frequency interference
and electromagnetic radiation in accordance with EN
55011. Marine use RFI lters are also available.
On enclosure size F drives, the Class A1 RFI lter requires
the addition of the options cabinet.
Selection of this option provides standardized terminal
connection and associated functionality as dened by
NAMUR NE37. NAMUR is an international association of
automation technology users in the process industries,
primarily chemical, and pharmaceutical industries in
Germany.

Brake chopper (IGBTs)
Brake terminals with an IGBT brake chopper circuit allow
for the connection of external brake resistors. For detailed
data on brake resistors, see the VLT® Brake Resistor MCE
101 Design Guide, available at drives.danfoss.com/downloads/portal/#/.
Regen terminals
Allow connection of regen units to the DC bus on the
capacitor bank side of the DC-link reactors for regenerative
braking. The enclosure size F regen terminals are sized for
approximately 50% the power rating of the drive. Consult
the factory for regen power limits based on the specic
drive size and voltage.
Load sharing terminals
These terminals connect to the DC-bus on the rectier side
of the DC-link reactor and allow for the sharing of DC bus
power between multiple drives. For drives with enclosure
size F, the load sharing terminals are sized for approximately 33% of the power rating of the drive. Consult the
factory for load sharing limits based on the specic drive
size and voltage.
Disconnect
A door-mounted handle allows for the manual operation of
a power disconnect switch to enable and disable power to
the drive, increasing safety during servicing. The
disconnect is interlocked with the cabinet doors to prevent
them from being opened while power is still applied.
Circuit breakers
A circuit breaker can be remotely tripped, but must be
manually reset. Circuit breakers are interlocked with the
cabinet doors to prevent them from being opened while
power is still applied. When a circuit breaker is ordered as
an option, fuses are also included for fast-acting current
overload protection of the AC drive.
Contactors
An electrically-controlled contactor switch allows for the
remote enabling and disabling of power to the drive. If the
IEC emergency stop option is ordered, the Pilz relay
monitors the auxiliary contact on the contactor.
Manual motor starters

often required for larger motors. Power for the starters is
provided from the load side of any supplied contactor,
circuit breaker, or disconnect switch. If a Class 1 RFI
option is ordered, the input side of the RFI provides the
power to the starter. Power is fused before each motor
starter and is o when the incoming power to the drive is
o. Up to 2 starters are allowed. If a 30 A fuse-protected
circuit is ordered, then only 1 starter is allowed. Starters
are integrated into the safe-stop circuit.
side of any supplied contactor, circuit breaker, or
disconnect switch. If a Class 1 RFI lter option is
ordered, the input side of the RFI provides the
power to the starter.
Common motor terminals
The common motor terminal option provides the busbars
and hardware required to connect the motor terminals
from the paralleled inverters to a single terminal (per
phase) to accommodate the installation of the motor-side
top entry kit.
This option is also recommended to connect the output of
a drive to an output lter or output contactor. The

2) Typical power loss is at normal conditions and expected to be within
values are based on a typical motor eciency (IE/IE3 border line). Lower eciency motors add to the power loss in the drive. Applies for
dimensioning of drive cooling. If the switching frequency is higher than the default setting, the power losses can increase. LCP and typical control
card power consumptions are included. For power loss data according to EN 50598-2, refer to drives.danfoss.com/knowledge-center/energy-
eciency-directive/#/. Options and customer load can add up to 30 W to the losses, though usually a fully loaded control card and options for
slots A and B each add only 4 W.
3) Measured using 5 m (16.5 ft) shielded motor cables at rated load and rated frequency. Eciency measured at nominal current. For energy
