Trip
A state entered in fault situations, e.g. if the frequency
converter is subject to an over-temperature or when the
frequency converter is protecting the motor, process or
mechanism. Restart is prevented until the cause of the
fault has disappeared and the trip state is cancelled by
activating reset or, in some cases, by being programmed
to reset automatically. Trip may not be used for personal
safety.
Trip Locked
A state entered in fault situations when the frequency
converter is protecting itself and requiring physical
intervention, e.g. if the frequency converter is subject to a
short circuit on the output. A locked trip can only be
cancelled by cutting off mains, removing the cause of the
fault, and reconnecting the frequency converter. Restart is
prevented until the trip state is cancelled by activating
reset or, in some cases, by being programmed to reset
automatically. Trip may not be used for personal safety.

Safety and ConformityFC 300 Design Guide
2 Safety and Conformity
2.1 Safety Precautions
WARNING
The voltage of the frequency converter is dangerous
whenever connected to mains. Incorrect installation of the
motor, frequency converter or fieldbus may cause death,
serious personal injury or damage to the equipment.
Consequently, the instructions in this manual, as well as
national and local rules and safety regulations, must be
complied with.
Safety Regulations
1.The mains supply to the frequency converter
must be disconnected whenever repair work is to
be carried out. Check that the mains supply has
been disconnected and that the necessary time
has elapsed before removing motor and mains
supply plugs.
2.The [OFF] button on the control panel of the
frequency converter does not disconnect the
mains supply and consequently it must not be
used as a safety switch.
3.The equipment must be properly earthed, the
user must be protected against supply voltage
and the motor must be protected against
overload in accordance with applicable national
and local regulations.
4.The earth leakage current exceeds 3.5mA.
5.Protection against motor overload is not included
in the factory setting. If this function is desired,
set 1-90 Motor Thermal Protection to data value
ETR trip 1 [4] or data value ETR warning 1 [3].
6.Do not remove the plugs for the motor and
mains supply while the frequency converter is
connected to mains. Check that the mains supply
has been disconnected and that the necessary
time has elapsed before removing motor and
mains plugs.
7.Please note that the frequency converter has
more voltage sources than L1, L2 and L3, when
load sharing (linking of DC intermediate circuit)
or external 24V DC are installed. Check that all
voltage sources have been disconnected and that
the necessary time has elapsed before
commencing repair work.
Warning against unintended start
1.The motor can be brought to a stop by means of
digital commands, bus commands, references or
a local stop, while the frequency converter is
22
connected to mains. If personal safety considerations (e.g. risk of personal injury caused by
contact with moving machine parts following an
unintentional start) make it necessary to ensure
that no unintended start occurs, these stop
functions are not sufficient. In such cases the
mains supply must be disconnected or the Safe
Stop function must be activated.
2.The motor may start while setting the
parameters. If this means that personal safety
may be compromised (e.g. personal injury caused
by contact with moving machine parts), motor
starting must be prevented, for instance by use
of the Safe Stop function or secure disconnection
of the motor connection.
3.A motor that has been stopped with the mains
supply connected, may start if faults occur in the
electronics of the frequency converter, through
temporary overload or if a fault in the power
supply grid or motor connection is remedied. If
unintended start must be prevented for personal
safety reasons (e.g. risk of injury caused by
contact with moving machine parts), the normal
stop functions of the frequency converter are not
sufficient. In such cases the mains supply must be
disconnected or the Safe Stop function must be
activated.
NOTE
When using the Safe Stop function, always follow the
instructions in the section Safe Stop of the VLT
AutomationDrive Design Guide.
4.Control signals from, or internally within, the
frequency converter may in rare cases be
activated in error, be delayed or fail to occur
entirely. When used in situations where safety is
critical, e.g. when controlling the electromagnetic
brake function of a hoist application, these
control signals must not be relied on exclusively.
MG.33.BD.02 - VLT® is a registered Danfoss trademark11
Safety and ConformityFC 300 Design Guide
WARNING
High Voltage
22
Touching the electrical parts may be fatal - even after the
equipment has been disconnected from mains.
Also make sure that other voltage inputs have been
disconnected, such as external 24V DC, load sharing
(linkage of DC intermediate circuit), as well as the motor
connection for kinetic back up.
Systems where frequency converters are installed must, if
necessary, be equipped with additional monitoring and
protective devices according to the valid safety regulations,
e.g law on mechanical tools, regulations for the prevention
of accidents etc. Modifications on the frequency converters
by means of the operating software are allowed.
NOTE
Hazardous situations shall be identified by the machine
builder/ integrator who is responsible for taking necessary
preventive means into consideration. Additional
monitoring and protective devices may be included, always
according to valid national safety regulations, e.g. law on
mechanical tools, regulations for the prevention of
accidents.
NOTE
Crane, Lifts and Hoists:
The controlling of external brakes must always have a
redundant system. The frequency converter can in no
circumstances be the primary safety circuit. Comply with
relevant standards, e.g.
Hoists and cranes: IEC 60204-32
Lifts: EN 81
The DC link capacitors remain charged after power has
been disconnected. Be aware that there may be high
voltage on the DC link even when the Control Card LEDs
are turned off. A red LED is mounted on a circuit board
inside the drive to indicate the DC bus voltage. The red
LED will stay lit until the DC link is 50 Vdc or lower. To
avoid electrical shock hazard, disconnect the frequency
converter from mains before carrying out maintenance.
When using a PM-motor, make sure it is disconnected.
Before doing service on the frequency converter wait at
least the amount of time indicated below:
Equipment containing electrical
components may not be disposed of
together with domestic waste.
It must be separately collected with
electrical and electronic waste according
to local and currently valid legislation.
FC 300
Design Guide
Software version: 6.4x
Protection Mode
Once a hardware limit on motor current or dc-link voltage
is exceeded the frequency converter will enter “Protection
mode”. “Protection mode” means a change of the PWM
modulation strategy and a low switching frequency to
minimize losses. This continues 10 sec after the last fault
and increases the reliability and the robustness of the
frequency converter while re-establishing full control of the
motor.
In hoist applications “Protection mode” is not usable
because the frequency converter will usually not be able to
leave this mode again and therefore it will extend the time
before activating the brake – which is not recommendable.
The “Protection mode” can be disabled by setting
14-26 Trip Delay at Inverter Fault to zero which means that
the frequency converter will trip immediately if one of the
hardware limits is exceeded.
NOTE
It is recommended to disable protection mode in hoisting
applications (14-26 Trip Delay at Inverter Fault = 0)
This Design Guide can be used for all FC 300 frequency
converters with software version 6.4x.
The software version number can be seen from 15-43 SoftwareVersion.
2.3.1 CE Conformity and Labelling
The machinery directive (2006/42/EC)
Frequency converters do not fall under the machinery
directive. However, if a frequency converter is supplied for
use in a machine, we provide information on safety
aspects relating to the frequency converter.
What is CE Conformity and Labelling?
The purpose of CE labelling is to avoid technical trade
obstacles within EFTA and the EU. The EU has introduced
the CE label as a simple way of showing whether a
product complies with the relevant EU directives. The CE
label says nothing about the specifications or quality of
12MG.33.BD.02 - VLT® is a registered Danfoss trademark
Safety and ConformityFC 300 Design Guide
the product. Frequency converters are regulated by two EU
directives:
The low-voltage directive (2006/95/EC)
Frequency converters must be CE labelled in accordance
with the low-voltage directive of January 1, 1997. The
directive applies to all electrical equipment and appliances
used in the 50 - 1000V AC and the 75 - 1500V DC voltage
ranges. Danfoss CE-labels in accordance with the directive
and issues a declaration of conformity upon request.
The EMC directive (2004/108/EC)
EMC is short for electromagnetic compatibility. The
presence of electromagnetic compatibility means that the
mutual interference between different components/
appliances does not affect the way the appliances work.
The EMC directive came into effect January 1, 1996.
Danfoss CE-labels in accordance with the directive and
issues a declaration of conformity upon request. To carry
out EMC-correct installation, see the instructions in this
Design Guide. In addition, we specify which standards our
products comply with. We offer the filters presented in the
specifications and provide other types of assistance to
ensure the optimum EMC result.
The frequency converter is most often used by professionals of the trade as a complex component forming part
of a larger appliance, system or installation. It must be
noted that the responsibility for the final EMC properties of
the appliance, system or installation rests with the installer.
What Is Covered
2.3.2
The EU "Guidelines on the Application of Council Directive2004/108/EC" outline three typical situations of using a
frequency converter. See below for EMC coverage and CE
labelling.
1.The frequency converter is sold directly to the
end-consumer. The frequency converter is for
example sold to a DIY market. The end-consumer
is a layman. He installs the frequency converter
himself for use with a hobby machine, a kitchen
appliance, etc. For such applications, the
frequency converter must be CE labelled in
accordance with the EMC directive.
2.The frequency converter is sold for installation in
a plant. The plant is built up by professionals of
the trade. It could be a production plant or a
heating/ventilation plant designed and installed
by professionals of the trade. Neither the
frequency converter nor the finished plant has to
be CE labelled under the EMC directive. However,
the unit must comply with the basic EMC
requirements of the directive. This is ensured by
using components, appliances, and systems that
are CE labelled under the EMC directive.
3.The frequency converter is sold as part of a
complete system. The system is being marketed
as complete and could e.g. be an air-conditioning
system. The complete system must be CE labelled
in accordance with the EMC directive. The
manufacturer can ensure CE labelling under the
EMC directive either by using CE labelled
components or by testing the EMC of the system.
If he chooses to use only CE labelled
components, he does not have to test the entire
system.
2.3.3 Danfoss Frequency Converter and CE
Labelling
CE labelling is a positive feature when used for its original
purpose, i.e. to facilitate trade within the EU and EFTA.
However, CE labelling may cover many different specifications. Thus, you have to check what a given CE label
specifically covers.
The covered specifications can be very different and a CE
label may therefore give the installer a false feeling of
security when using a frequency converter as a component
in a system or an appliance.
Danfoss CE labels the frequency converters in accordance
with the low-voltage directive. This means that if the
frequency converter is installed correctly, we guarantee
compliance with the low-voltage directive. Danfoss issues a
declaration of conformity that confirms our CE labelling in
accordance with the low-voltage directive.
The CE label also applies to the EMC directive provided
that the instructions for EMC-correct installation and
filtering are followed. On this basis, a declaration of
conformity in accordance with the EMC directive is issued.
The Design Guide offers detailed instructions for installation to ensure EMC-correct installation. Furthermore,
Danfoss specifies which our different products comply
with.
Danfoss provides other types of assistance that can help
you obtain the best EMC result.
2.3.4
Compliance with EMC Directive
2004/108/EC
As mentioned, the frequency converter is mostly used by
professionals of the trade as a complex component
forming part of a larger appliance, system, or installation. It
must be noted that the responsibility for the final EMC
properties of the appliance, system or installation rests
22

system. The standards and test levels stated for Power
22
Drive systems are complied with, provided that the EMCcorrect instructions for installation are followed, see the
section EMC Immunity.
The frequency converter has been designed to meet the
IEC/EN 60068-2-3 standard, EN 50178 pkt. 9.4.2.2 at 50°C.
A frequency converter contains a large number of
mechanical and electronic components. All are to some
extent vulnerable to environmental effects.
CAUTION
The frequency converter should not be installed in
environments with airborne liquids, particles, or gases
capable of affecting and damaging the electronic
components. Failure to take the necessary protective
measures increases the risk of stoppages, thus reducing
the life of the frequency converter.
Degree of protection as per IEC 60529
The safe Stop function may only be installed and operated
in a control cabinet with degree of protection IP54 or
higher (or equivalent environment). This is required to
avoid cross faults and short circuits between terminals,
connectors, tracks and safety-related circuitry caused by
foreign objects.
NOTE
Mounting frequency converters in aggressive environments
increases the risk of stoppages and considerably reduces
the life of the converter.
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.
D and E enclosures have a stainless steel back-channel
option to provide additional protection in aggressive
environments. Proper ventilation is still required for the
internal components of the drive. Contact Danfoss for
additional information.
The frequency converter has been tested according to the
procedure based on the shown standards:
The frequency converter complies with requirements that
exist for units mounted on the walls and floors of
production premises, as well as in panels bolted to walls or
floors.
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 IP
54/55. As an extra protection, coated printed circuit boards
can be ordered as an option.
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 very
dusty environments, use equipment with enclosure rating
IP 54/55 or a cabinet for IP 00/IP 20/TYPE 1 equipment.
In environments with high temperatures and humidity,
corrosive gases such as sulphur, nitrogen, and chlorine
compounds will cause chemical processes on the
frequency converter components.
Such chemical reactions will rapidly affect and damage the
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.

Introduction to FC 300FC 300 Design Guide
3.2.1 Control Principle
A frequency converter rectifies AC voltage from mains into
DC voltage, after which this DC voltage is converted into a
AC current with a variable amplitude and frequency.
The motor is supplied with variable voltage / current and
frequency, which enables infinitely variable speed control
of three-phased, standard AC motors and permanent
magnet synchronous motors.
3.2.2 FC 300 Controls
The frequency converter is capable of controlling either
the speed or the torque on the motor shaft. Setting
1-00 Configuration Mode determines the type of control.
Speed control:
There are two types of speed control:
Speed open loop control which does not require
•
any feedback from motor (sensorless).
Speed closed loop PID control requires a speed
•
feedback to an input. A properly optimised speed
closed loop control will have higher accuracy
than a speed open loop control.
Selects which input to use as speed PID feedback in
7-00 Speed PID Feedback Source.
Speed / torque reference:
The reference to these controls can either be a single
refrence or be the sum of various references including
relatively scaled references. The handling of references is
explained in detail later in this section.
3
3
Torque control (FC 302 only):
The torque control function is used in applications where
the torque on motor output shaft is controlling the
application as tension control. Torque control can be
selected in par. 1-00, either in VVC+ open loop [4] or Flux
control closed loop with motor speed feedback [2]. Torque
setting is done by setting an analog, digital or bus
controlled reference. The max speed limit factor is set in
par. 4-21. When running torque control it is recommended
to make a full AMA procedure as the correct motor data
are of high importance for optimal performance.
Closed loop in Flux mode with encoder feedback
•
offers superior performance in all four quadrants
and at all motor speeds.
Open loop in VVC+ mode. The function is used in
•
mechanical robust applications, but the accuracy
is limited. Open loop torque function works
basically only in one speed direction. The torque
is calculated on basic of current measurement
internal in the frequency converter. See
Application Example Torque open Loop

3.2.3 FC 301 vs. FC 302 Control Principle
3
FC 301 is a general purpose frequency converter for variable speed applications. The control principle is based on Voltage
Vector Control (VVC
plus
).
FC 301 can handle asynchronous motors only.
The current sensing principle in FC 301 is based on current measurement in the DC link or motor phase. The ground fault
protection on the motor side is solved by a de-saturation circuit in the IGBTs connected to the control board.
Short circuit behaviour on FC 301 depends on the current transducer in the positive DC link and the desaturation protection
with feedback from the 3 lower IGBT's and the brake.
Illustration 3.1 FC 301
FC 302 is a high performance frequency converter for demanding applications. The frequency converter can handle various
kinds of motor control principles such as U/f special motor mode, VVC
plus
or Flux Vector motor control.
FC 302 is able to handle Permanent Magnet Synchronous Motors (Brushless servo motors) as well as normal squirrel cage
asynchronous motors.
Short circuit behaviour on FC 302 depends on the 3 current transducers in the motor phases and the desaturation
protection with feedback from the brake.

In the configuration shown in Illustration 3.3, 1-01 Motor Control Principle is set to “VVC
plus
[1]” and 1-00 Configuration Mode is
set to “Speed open loop [0]”. The resulting reference from the reference handling system is received and fed through the
ramp limitation and speed limitation before being sent to the motor control. The output of the motor control is then
limited by the maximum frequency limit.
If 1-00 Configuration Mode is set to “Speed closed loop [1]” the resulting reference will be passed from the ramp limitation
and speed limitation into a speed PID control. The Speed PID control parameters are located in the parameter group 7-0*.
The resulting reference from the Speed PID control is sent to the motor control limited by the frequency limit.
Select “Process [3]” in 1-00 Configuration Mode to use the process PID control for closed loop control of e.g. speed or
pressure in the controlled application. The Process PID parameters are located in parameter group 7-2* and 7-3*.

Select “Speed closed loop [1]” in 1-00 Configuration Mode to use the resulting reference as an input for the Speed PID
control. The Speed PID control parameters are located in parameter group 7-0*.
Select “Torque [2]” in 1-00 Configuration Mode to use the resulting reference directly as a torque reference. Torque control
can only be selected in the Flux with motor feedback (1-01 Motor Control Principle) configuration. When this mode has been
selected, the reference will use the Nm unit. It requires no torque feedback, since the actual torque is calculated on the
basis of the current measurement of the frequency converter.
Select “Process [3]” in 1-00 Configuration Mode to use the process PID control for closed loop control of e.g. speed or a
process variable in the controlled application.

Mode
The frequency converter features an integral current limit
control which is activated when the motor current, and
thus the torque, is higher than the torque limits set in
4-16 Torque Limit Motor Mode, 4-17 Torque Limit Generator
Mode and 4-18 Current Limit.
When the frequency converter is at the current limit during
motor operation or regenerative operation, the frequency
converter will try to get below the preset torque limits as
quickly as possible without losing control of the motor.

frequency converter is controlled ([Hz], [RPM],
[Nm] etc.).
2.Y- (the relative reference): A sum of one fixed
preset reference (3-14 Preset Relative Reference)
and one variable analog reference (3-18 RelativeScaling Reference Resource) in [%].
The two types of reference inputs are combined in the
following formula: Remote reference = X + X * Y / 100%. If
relative reference is not used par. 3-18 must be set to Nofunction and par. 3-14 to 0%. The catch up / slow down
function and the freeze reference function can both be
activated by digital inputs on the frequency converter. The
functions and parameters are described in the
Programming Guide, MG33MXYY.
The scaling of analog references are described in
parameter groups 6-1* and 6-2*, and the scaling of digital
pulse references are described in parameter group 5-5*.
Reference limits and ranges are set in parameter group
3-0*.
Reference Limits
3.3.1
3-00 Reference Range , 3-02 Minimum Reference and
3-03 Maximum Reference together define the allowed range
of the sum of all references. The sum of all references are
clamped when necessary. The relation between the
resulting reference (after clamping) and the sum of all
references is shown below.
The value of 3-02 Minimum Reference can not be set to less
than 0, unless1-00 Configuration Mode is set to [3] Process.
In that case the following relations between the resulting
reference (after clamping) and the sum of all references is
as shown in Illustration 3.4.

3.3.2 Scaling of Preset References and Bus

Preset references are scaled according to the following
rules:
When 3-00 Reference Range : [0] Min - Max 0%
•
reference equals 0 [unit] where unit can be any
unit e.g. rpm, m/s, bar etc. 100% reference equals
the Max (abs (3-03 Maximum Reference ), abs
(3-02 Minimum Reference)).
When 3-00 Reference Range : [1] -Max - +Max 0%
•
reference equals 0 [unit] -100% reference equals Max Reference 100% reference equals Max

Bus references are scaled according to the following rules:
When 3-00 Reference Range: [0] Min - Max. To
•
obtain max resolution on the bus reference the
scaling on the bus is: 0% reference equals Min
Reference and 100% reference equals Max
reference.

3.3.3
References and feedback are scaled from analog and pulse
inputs in the same way. The only difference is that a
reference above or below the specified minimum and
maximum “endpoints” (P1 and P2 in Illustration 3.5) are
clamped whereas a feedback above or below is not.

3.3.4 Dead Band Around Zero
In some cases the reference (in rare cases also the
feedback) should have a Dead Band around zero (i.e. to
make sure the machine is stopped when the reference is
“near zero”).
To make the dead band active and to set the amount of
dead band, the following settings must be done:
Either Minimum Reference Value (see table above
•
for relevant parameter) or Maximum Reference
Value must be zero. In other words; Either P1 or
P2 must be on the X-axis in the graph below.
And both points defining the scaling graph are in
•
the same quadrant.
The size of the Dead Band is defined by either P1 or P2 as
shown inIllustration 3.6.

Thus a reference endpoint of P1 = (0 V, 0 RPM) will not
result in any dead band, but a reference endpoint of e.g.
P1 = (1V, 0 RPM) will result in a -1V to +1V dead band in
this case provided that the end point P2 is placed in either
Quadrant 1 or Quadrant 4.

“N.A.” means that the specific mode is not available at all. “Not Active” means that the specific mode is available but the Speed Control is not

NOTE
The Speed Control PID will work under the default parameter setting, but tuning the parameters is highly recommended to
optimize the motor control performance. The two Flux motor control principles are particularly dependant on proper tuning
to yield their full potential.
The following parameters are relevant for the Speed Control:

7-03 Speed PID Integral Time
7-04 Speed PID Differentiation Time
7-05 Speed PID Diff. Gain Limit

Select from which input the Speed PID should get its feedback.
The higher the value - the quicker the control. However, too high value may lead to oscillations.
Eliminates steady state speed error. Lower value means quick reaction. However, too low value may lead to
oscillations.
Provides a gain proportional to the rate of change of the feedback. A setting of zero disables the differentiator.
If there are quick changes in reference or feedback in a given application - which means that the error changes
swiftly - the differentiator may soon become too dominant. This is because it reacts to changes in the error. The
quicker the error changes, the stronger the differentiator gain is. The differentiator gain can thus be limited to allow
setting of the reasonable differentiation time for slow changes and a suitably quick gain for quick changes.
A low-pass filter that dampens oscillations on the feedback signal and improves steady state performance. However,
too large filter time will deteriorate the dynamic performance of the Speed PID control.

Example of how to Programme the Speed Control
In this case the Speed PID Control is used to maintain a
constant motor speed regardless of the changing load on
the motor. The required motor speed is set via a potentiometer connected to terminal 53. The speed range is 0 1500 RPM corresponding to 0 - 10V over the
potentiometer. Starting and stopping is controlled by a
switch connected to terminal 18. The Speed PID monitors
the actual RPM of the motor by using a 24V (HTL)
incremental encoder as feedback. The feedback sensor is
an encoder (1024 pulses per revolution) connected to
terminals 32 and 33.

The following must be programmed in order shown (see explanation of settings in the Programming Guide)
In the list it is assumed that all other parameters and switches remain at their default setting.
Functionparameter no.Setting
1) Make sure the motor runs properly. Do the following:
Set the motor parameters using name plate data1-2*As specified by motor name plate
Have the frequency converter makes an Automatic Motor
Adaptation
2) Check the motor is running and the encoder is attached properly. Do the following:
Press the “Hand On” LCP key. Check that the motor is running
and note in which direction it is turning (henceforth referred to
as the “positive direction”).
Go to 16-20 Motor Angle. Turn the motor slowly in the positive
direction. It must be turned so slowly (only a few RPM) that it
can be determined if the value in 16-20 Motor Angle is increasing
or decreasing.
If 16-20 Motor Angle is decreasing then change the encoder
direction in 5-71 Term 32/33 Encoder Direction.
3) Make sure the drive limits are set to safe values
Set acceptable limits for the references.
Check that the ramp settings are within drive capabilities and
allowed application operating specifications.
Set acceptable limits for the motor speed and frequency.
4) Configure the Speed Control and select the Motor Control principle
Activation of Speed Control
Selection of Motor Control Principle
5) Configure and scale the reference to the Speed Control

The following tuning guidelines are relevant when using
one of the Flux motor control principles in applications
where the load is mainly inertial (with a low amount of
friction).
The value of 30-83 Speed PID Proportional Gain is
dependent on the combined inertia of the motor and load,
and the selected bandwidth can be calculated using the
following formula:

NOTE
1-20 Motor Power [kW] is the motor power in [kW] (i.e.
enter ‘4’ kW instead of ‘4000’ W in the formula).
A practical value for the Bandwith is 20 rad/s. Check the
result of the 30-83 Speed PID Proportional Gain calculation

using a high resolution feedback such as a SinCos

For incremental encoders the Encoder Resolution is found
in either 5-70 Term 32/33 Pulses per Revolution (24V HTL on
standard drive) or 17-11 Resolution (PPR) (5V TTL on
MCB102 Option).
Generally the practical maximum limit of 30-83 Speed PIDProportional Gain is determined by the encoder resolution
and the feedback filter time but other factors in the
application might limit the 30-83 Speed PID ProportionalGain to a lower value.
To minimize the overshoot, 7-03 Speed PID Integral Time
could be set to approx. 2.5 sec. (varies with the
application).
7-04 Speed PID Differentiation Time should be set to 0 until
everything else is tuned. If necessary finish the tuning by
experimenting with small increments of this setting.
Process PID Control
3.4.3
The Process PID Control can be used to control application
parameters that can be measured by a sensor (i.e.
pressure, temperature, flow) and be affected by the
connected motor through a pump, fan or otherwise.
The table shows the control configurations where the
Process Control is possible. When a Flux Vector motor
control principle is used, take care also to tune the Speed
Control PID parameters. Refer to the section about the
Control Structure to see where the Speed Control is active.

Select from which Source (i.e. analog or pulse input) the Process PID should get its feedback
Optional: Determine if (and from where) the Process PID should get an additional feedback signal. If
an additional feedback source is selected the two feedback signals will be added together before
being used in the Process PID Control.
Under [0] Normal operation the Process Control will respond with an increase of the motor speed if
the feedback is getting lower than the reference. In the same situation, but under [1] Inverse
operation, the Process Control will respond with a decreasing motor speed instead.
The anti windup function ensures that when either a frequency limit or a torque limit is reached, the
integrator will be set to a gain that corresponds to the actual frequency. This avoids integrating on an
error that cannot in any case be compensated for by means of a speed change. This function can be
disabled by selecting [0] “Off”.
In some applications, reaching the required speed/set point can take a very long time. In such
applications it might be an advantage to set a fixed motor speed from the frequency converter before
the process control is activated. This is done by setting a Process PID Start Value (speed) in
7-32 Process PID Start Speed.
The higher the value - the quicker the control. However, too large value may lead to oscillations.
Eliminates steady state speed error. Lower value means quick reaction. However, too small value may
lead to oscillations.
Provides a gain proportional to the rate of change of the feedback. A setting of zero disables the
differentiator.
If there are quick changes in reference or feedback in a given application - which means that the error
changes swiftly - the differentiator may soon become too dominant. This is because it reacts to
changes in the error. The quicker the error changes, the stronger the differentiator gain is. The differentiator gain can thus be limited to allow setting of the reasonable differentiation time for slow
changes.
In application where there is a good (and approximately linear) correlation between the process
reference and the motor speed necessary for obtaining that reference, the Feed Forward Factor can be
used to achieve better dynamic performance of the Process PID Control.
If there are oscillations of the current/voltage feedback signal, these can be dampened by means of a
low-pass filter. This time constant represents the speed limit of the ripples occurring on the feedback
signal.
Example: If the low-pass filter has been set to 0.1s, the limit speed will be 10 RAD/sec. (the reciprocal
of 0.1 s), corresponding to (10/(2 x π)) = 1.6 Hz. This means that all currents/voltages that vary by
more than 1.6 oscillations per second will be damped by the filter. The control will only be carried out
on a feedback signal that varies by a frequency (speed) of less than 1.6 Hz.
The low-pass filter improves steady state performance but selecting a too large filter time will
deteriorate the dynamic performance of the Process PID Control.

3.4.4 Example of Process PID Control
The following is an example of a Process PID Control used
in a ventilation system:
In a ventilation system, the temperature is to be settable
from - 5 - 35°C with a potentiometer of 0-10V. The set
temperature must be kept constant, for which purpose the
Process Control is to be used.
The control is of the inverse type, which means that when
the temperature increases, the ventilation speed is
increased as well, so as to generate more air. When the
temperature drops, the speed is reduced. The transmitter
used is a temperature sensor with a working range of

Temperature feedback via transmitter (-10-40°C,

Optimisation of the process regulator
The basic settings have now been made; all that needs to
be done is to optimise the proportional gain, the
integration time and the differentiation time (7-33 Process
PID Proportional Gain, 7-34 Process PID Integral Time,
7-35 Process PID Differentiation Time). In most processes,
this can be done by following the guidelines given below.
1.Start the motor
2.
Set 7-33 Process PID Proportional Gain to 0.3 and
increase it until the feedback signal again begins
to vary continuously. Then reduce the value until
the feedback signal has stabilised. Now lower the
proportional gain by 40-60%.
3.
Set 7-34 Process PID Integral Time to 20 sec. and
reduce the value until the feedback signal again
begins to vary continuously. Increase the
integration time until the feedback signal
stabilises, followed by an increase of 15-50%.
4.
Only use 7-35 Process PID Differentiation Time for
very fast-acting systems only (differentiation
time). The typical value is four times the set
integration time. The differentiator should only be
used when the setting of the proportional gain
and the integration time has been fully
optimised. Make sure that oscillations on the
feedback signal is sufficiently dampened by the
lowpass filter on the feedback signal.
If necessary, start/stop can be activated a number of times
in order to provoke a variation of the feedback signal.
3.4.5 Ziegler Nichols Tuning Method
In order to tune the PID controls of the frequency
converter, several tuning methods can be used. One
approach is to use a technique which was developed in

the 1950s but which has stood the test of time and is still
used today. This method is known as the Ziegler Nichols
tuning method.
The method described must not be used on applications
that could be damaged by the oscillations created by
marginally stable control settings.
The criteria for adjusting the parameters are based on
evaluating the system at the limit of stability rather than
on taking a step response. We increase the proportional
gain until we observe continuous oscillations (as measured
on the feedback), that is, until the system becomes
marginally stable. The corresponding gain (Ku) is called the
ultimate gain. The period of the oscillation (Pu) (called the
ultimate period) is determined as shown in the figure.
Step 1: Select only Proportional Control, meaning that the
Integral time is selected to the maximum value, while the
differentiation time is selected to zero.
Step 2: Increase the value of the proportional gain until
the point of instability is reached (sustained oscillations)
and the critical value of gain, Ku, is reached.
Step 3: Measure the period of oscillation to obtain the
critical time constant, Pu.
Step 4: Use the table above to calculate the necessary PID
control parameters.
Illustration 3.8 Marginally Stable System
Pu should be measured when the amplitude of oscillation
is quite small. Then we “back off” from this gain again, as
shown in Table 1.
Ku is the gain at which the oscillation is obtained.

3.5 General Aspects of EMC
3.5.1 General Aspects of EMC Emissions
Electrical interference is usually conducted at frequencies in the range 150kHz to 30MHz. Airborne interference from the
frequency converter system in the range 30MHz to 1GHz is generated from the inverter, motor cable, and the motor.
As shown in the illustration below, capacitive currents in the motor cable coupled with a high dU/dt from the motor
voltage generate leakage currents.
The use of a screened motor cable increases the leakage current (see illustration below) because screened cables have
higher capacitance to earth than unscreened cables. If the leakage current is not filtered, it will cause greater interference
on the mains in the radio frequency range below approximately 5MHz. Since the leakage current (I1) is carried back to the
unit through the screen (I 3), there will in principle only be a small electro-magnetic field (I4) from the screened motor cable
according to the below figure.
The screen reduces the radiated interference but increases the low-frequency interference on the mains. The motor cable
screen must be connected to the frequency converter enclosure as well as on the motor enclosure. This is best done by
using integrated screen clamps so as to avoid twisted screen ends (pigtails). These increase the screen impedance at higher
frequencies, which reduces the screen effect and increases the leakage current (I4).
If a screened cable is used for fieldbus, relay, control cable, signal interface and brake, the screen must be mounted on the
enclosure at both ends. In some situations, however, it will be necessary to break the screen to avoid current loops.
3
3
If the screen is to be placed on a mounting plate for the frequency converter, the mounting plate must be made of metal,
because the screen currents have to be conveyed back to the unit. Moreover, ensure good electrical contact from the
mounting plate through the mounting screws to the frequency converter chassis.
When unscreened cables are used, some emission requirements are not complied with, although the immunity
requirements are observed.
In order to reduce the interference level from the entire system (unit + installation), make motor and brake cables as short
as possible. Avoid placing cables with a sensitive signal level alongside motor and brake cables. Radio interference higher
than 50MHz (airborne) is especially generated by the control electronics. Please see for more information on EMC.

3.5.4 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 office environment. All
Danfoss frequency converters comply with the requirements for the industrial environment and consequently comply also
with the lower requirements for home and office environment with a large safety margin.
In order to document immunity against electrical interference from electrical phenomena, the following immunity tests have
been made on a system consisting of a frequency converter (with options if relevant), a screened control cable and a
control box with potentiometer, motor cable and motor.
The tests were performed in accordance with the following basic standards:
EN 61000-4-2 (IEC 61000-4-2): Electrostatic discharges (ESD): Simulation of electrostatic discharges from human
•
beings.
EN 61000-4-3 (IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude modulated simulation of the

3.6.1 PELV - Protective Extra Low Voltage
PELV offers protection by way of extra low voltage.
Protection against electric shock is ensured when the
electrical supply is of the PELV type and the installation is
made as described in local/national regulations on PELV
supplies.
All control terminals and relay terminals 01-03/04-06
comply with PELV (Protective Extra Low Voltage) (Does not
apply to grounded Delta leg above 400V).
Galvanic (ensured) isolation is obtained by fulfilling
requirements for higher isolation and by providing the
relevant creapage/clearance distances. These requirements
are described in the EN 61800-5-1 standard.
The components that make up the electrical isolation, as
described below, also comply with the requirements for
higher isolation and the relevant test as described in EN
61800-5-1.
The PELV galvanic isolation can be shown in six locations
(see Illustration 3.9):
In order to maintain PELV all connections made to the
control terminals must be PELV, e.g. thermistor must be
reinforced/double insulated.
The functional galvanic isolation (a and b on drawing) is
for the 24V back-up option and for the RS485 standard bus
interface.
WARNING
Installation at high altitude:
380 - 500V, enclosure A, B and C: At altitudes above 2km,
please contact Danfoss regarding PELV.
380 - 500V, enclosure D, E and F: At altitudes above 3km,
please contact Danfoss regarding PELV.
525 - 690V: At altitudes above 2km, please contact Danfoss
regarding PELV.
WARNING
Touching the electrical parts could be fatal - even after the
equipment has been disconnected from mains.
Also make sure that other voltage inputs have been
disconnected, such as load sharing (linkage of DC
intermediate circuit), as well as the motor connection for
kinetic back-up.
Before touching any electrical parts, wait at least the
amount of time indicated in the Safety Precautions section.
Shorter time is allowed only if indicated on the nameplate
for the specific unit.

Illustration 3.9 Galvanic Isolation
Follow national and local codes regarding protective

Frequency converter technology implies high frequency
switching at high power. This will generate a leakage
current in the earth connection. A fault current in the
frequency converter at the output power terminals might
contain a DC component which can charge the filter
capacitors and cause a transient earth current.
The earth leakage current is made up of several contributions and depends on various system configurations
including RFI filtering, screened motor cables, and
frequency converter power.

See also RCD Application Note, MN.90.GX.02.
NOTE
When a filter is used, turn off 14-50 RFI Filter when
charging the filter, to avoid that a high leakage current
makes the RCD switch.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5mA.
Earth grounding must be reinforced in one of the
following ways:
Earth ground wire (terminal 95) of at least 10mm
•
Two separate earth ground wires both complying
•
with the dimensioning rules
See EN/IEC61800-5-1 and EN50178 for further information.
Using RCDs
Where residual current devices (RCDs), also known as earth
leakage circuit breakers (ELCBs), are used, comply with the
following:
Use RCDs of type B only which are capable of
detecting AC and DC currents
Use RCDs with an inrush delay to prevent faults
due to transient earth currents
Dimension RCDs according to the system configuration and environmental considerations
3.8 Brake Functions in FC 300
Braking function is applied for braking the load on the
motor shaft, either as dynamic braking or static braking.
Mechanical Holding Brake
3.8.1
A mechanical holding brake mounted directly on the
motor shaft normally performs static braking. In some
applications the static holding torque is working as static
holding of the motor shaft (usually synchronous
2
permanent motors). A holding brake is either controlled by
a PLC or directly by a digital output from the frequency
converter (relay or solid state).
When the holding brake is included in a safety chain:
A frequency converter cannot provide a safe control of a
mechanical brake. A redundancy circuitry for the brake
control must be included in the total installation.

3.8.2 Dynamic Braking
Dynamic Brake established by:
Resistor brake: A brake IGBT keep the overvoltage
•
under a certain threshold by directing the brake
energy from the motor to the connected brake
resistor (par. 2-10 = [1]).
AC brake: The brake energy is distributed in the
•
motor by changing the loss conditions in the
motor. The AC brake function cannot be used in
applications with high cycling frequency since
this will overheat the motor (par. 2-10 = [2]).
DC brake: An over-modulated DC current added
•
to the AC current works as an eddy current brake
(par. 2-02 ≠ 0 sec. ).
Selection of Brake Resistor
3.8.3
To handle higher demands by generatoric braking a brake
resistor is necessary. Using a brake resistor ensures that the
energy is absorbed in the brake resistor and not in the
frequency converter. For more information see the Brake
Resistor Design Guide, MG.90.OX.YY.
braking time also called intermittent duty cycle. The
resistor intermittent duty cycle is an indication of the duty
cycle at which the resistor is active. The below figure
shows a typical braking cycle.
Motor suppliers often use S5 when stating the permissible
load which is an expression of intermittent duty cycle.
The intermittent duty cycle for the resistor is calculated as
follows:
Duty cycle = tb/T
T = cycle time in seconds
tb is the braking time in seconds (of the cycle time)
3

If the amount of kinetic energy transferred to the resistor
in each braking period is not known, the average power
can be calculated on the basis of the cycle time and

Danfoss offers brake resistors with duty cycle of 5%, 10%
and 40%. If a 10% duty cycle is applied, the brake resistors
are able to absorb brake power for 10% of the cycle time.
The remaining 90% of the cycle time will be used on
dissipating excess heat.
Make sure the resistor is designed to handle the required
braking time.
The max. permissible load on the brake resistor is stated as
a peak power at a given intermittent duty cycle and can
be calculated as:

NOTE
The resistor brake circuit resistance selected should not be
higher than that recommended by Danfoss. If a brake
resistor with a higher ohmic value is selected, the 160%
braking torque may not be achieved because there is a risk
that the frequency converter cuts out for safety reasons.
NOTE
If a short circuit in the brake transistor occurs, power
dissipation in the brake resistor is only prevented by using
a mains switch or contactor to disconnect the mains for
the frequency converter. (The contactor can be controlled
by the frequency converter).

NOTE
Do not touch the brake resistor as it can get very hot
while/after braking. The brake resistor must be placed in a
secure environment to avoid fire risk
D-F size frequency converters contain more than one brake
chopper. Consequently, use one brake resistor per brake
chopper for those frame sizes.
3.8.4 Control with Brake Function
The brake is protected against short-circuiting of the brake
resistor, and the brake transistor is monitored to ensure
that short-circuiting of the transistor is detected. A relay/
digital output can be used for protecting the brake resistor
against overloading in connection with a fault in the
frequency converter.
In addition, the brake makes it possible to read out the
momentary power and the mean power for the latest 120
seconds. The brake can also monitor the power energizing
and make sure it does not exceed a limit selected in
2-12 Brake Power Limit (kW). In 2-13 Brake Power Monitoring,
select the function to carry out when the power
transmitted to the brake resistor exceeds the limit set in
2-12 Brake Power Limit (kW).

NOTE
Monitoring the brake power is not a safety function; a
thermal switch is required for that purpose. The brake
resistor circuit is not earth leakage protected.
Over voltage control (OVC) (exclusive brake resistor) can be
selected as an alternative brake function in 2-17 Over-voltage Control. This function is active for all units. The
function ensures that a trip can be avoided if the DC link
voltage increases. This is done by increasing the output
frequency to limit the voltage from the DC link. It is a very
useful function, e.g. if the ramp-down time is too short
since tripping of the frequency converter is avoided. In this
situation the ramp-down time is extended.
Mechanical Brake Control
3.9.1
For hoisting applications, it is necessary to be able to
control an electro-magnetic brake. For controlling the
brake, a relay output (relay1 or relay2) or a programmed
digital output (terminal 27 or 29) is required. Normally, this
output must be closed for as long as the frequency
converter is unable to ’hold’ the motor, e.g. because of too
big load. In 5-40 Function Relay (Array parameter),
5-30 Terminal 27 Digital Output, or 5-31 Terminal 29 Digital
Output, select mechanical brake control [32] for applications
with an electro-magnetic brake.
When mechanical brake control [32] is selected, the
mechanical brake relay stays closed during start until the
output current is above the level selected in 2-20 ReleaseBrake Current. During stop, the mechanical brake will close
when the speed is below the level selected in 2-21 ActivateBrake Speed [RPM]. If the frequency converter is brought
into an alarm condition, i.e. over-voltage situation, the
mechanical brake immediately cuts in. This is also the case
during safe stop.

out a stop command.
NOTE
For vertical lifting or hoisting applications it is strongly
recommended to ensure that the load can be stopped in
case of an emergency or a malfunction of a single t such
as a contactor, etc.
If the frequency converter is in alarm mode or in an over
voltage situation, the mechanical brake cuts in.
NOTE
For hoisting applications make sure that the torque limits
in 4-16 Torque Limit Motor Mode and 4-17 Torque Limit
Generator Mode are set lower than the current limit in

3.9.2 Hoist Mechanical Brake
The VLT AutomationDrive features a mechanical brake
control specifically designed for hoisting applications. The
hoist mechanical brake is activated by choice [6] in
1-72 Start Function. The main difference comed to the
regular mechanical brake control, where a relay function
monitoring the output current is used, is that the hoist
mechanical brake function has direct control over the
brake relay. This means that instead of setting a current for
release of the brake, the torque applied against the closed
brake before release is defined. Because the torque is
defined directly the setup is more straightforward for
hoisting applications.
By using
releasing the brake can be obtained. The hoist mechanical
brake strategy is based on a 3-step sequence, where motor
control and brake release are synchronized in order to
obtain the smoothest possible brake release.
3-step sequence
2-28 Gain Boost Factor a quicker control when
1.Pre-magnetize the motor
In order to ensure that there is a hold on the
motor and to verify that it is mounted correctly,
the motor is first pre-magnetized.
2.Apply torque against the closed brake
When the load is held by the mechanical brake,
its size cannot be determined, only its direction.
The moment the brake opens, the load must be
taken over by the motor. To facilitate the
takeover, a user defined torque, set in
2-26 Torque Ref, is applied in hoisting direction.
This will be used to initialize the speed controller
that will finally take over the load. In order to
reduce wear on the gearbox due to backlash, the
torque is ramped up.
3.Release brake
When the torque reaches the value set in
2-26 Torque Ref the brake is released. The value
set in 2-25 Brake Release Time determines the
delay before the load is released. In order to react
as quickly as possible on the load-step that
follows upon brake release, the speed-PID control
can be boosted by increasing the proportional
gain.

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. That will lead to an associated

Events and actions are each numbered and linked together
in pairs (states). This means that when event [0] is fulfilled
(attains the value TRUE), action [0] is executed. After this,
the conditions of event [1] will be evaluated and if
evaluated TRUE, action [1] will be executed and so on.

3.11 Extreme Running Conditions
Short Circuit (Motor Phase – Phase)
The frequency converter is protected against short circuits
by means of current measurement in each of the three
motor phases or in the DC link. A short circuit between
two output phases will cause an overcurrent in the
inverter. The inverter will be turned off individually when
the short circuit current exceeds the permitted value
(Alarm 16 Trip Lock).
To protect the frequency converter against a short circuit
at the load sharing and brake outputs please see the
design guidelines.
See certificate in 3.9 Certificates.
Switching on the Output
Switching on the output between the motor and the
frequency converter is fully permitted. You cannot damage
the frequency converter in any way by switching on the
output. However, fault messages may appear.
Motor-generated Over-voltage
The voltage in the intermediate circuit is increased when
the motor acts as a generator. This occurs in following
cases:
1.The load drives the motor (at constant output
frequency from the frequency converter), ie. the
load generates energy.
2.During deceleration ("ramp-down") if the moment
of inertia 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.
3.Incorrect slip compensation setting may cause
higher DC link voltage.
The control unit may attempt to correct the ramp if
possible (2-17 Over-voltage Control.
The inverter turns off to protect the transistors and the
intermediate circuit capacitors when a certain voltage level
is reached.
See 2-10 Brake Function and 2-17 Over-voltage Control to
select the method used for controlling the intermediate
circuit voltage level.
plus
Static Overload in VVC
When the frequency converter is overloaded (the torque
limit in 4-16 Torque Limit Motor Mode/4-17 Torque LimitGenerator Mode is reached), the controls reduces the
output frequency to reduce the load.
If the overload is excessive, a current may occur that
makes the frequency converter cut out after approx. 5-10
sec.
Operation within the torque limit is limited in time (0-60
sec.) in 14-25 Trip Delay at Torque Limit.
mode
3.11.1 Motor Thermal Protection
To protect the application from serious damages VLT
AutomationDrive offers several dedicated features
Torque Limit: The Torque limit feature the motor is
protected for being overloaded independent of the speed.
Torque limit is controlled in 4-16 Torque Limit Motor Mode
and or 4-17 Torque Limit Generator Mode and the time
before the torque limit warning shall trip is controlled in
14-25 Trip Delay at Torque Limit.
Current Limit: The current limit is controlled in 4-18 CurrentLimit and the time before the current limit warning shall
trip is controlled in 14-24 Trip Delay at Current Limit.
Min Speed Limit: (4-11 Motor Speed Low Limit [RPM] or
4-12 Motor Speed Low Limit [Hz]) limit the operating speed
range to for instance between 30 and 50/60Hz. Max Speed
Limit: (4-13 Motor Speed High Limit [RPM] or 4-19 MaxOutput Frequency) limit the max output speed the drive
can provide
ETR (Electronic Thermal relay): The frequency converter ETR
function measures actual current, speed and time to
calculate motor temperature and protect 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 the following figure:

3
Mains Drop-out
During a mains drop-out, the frequency converter keeps
running until the intermediate circuit 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 inverter to coast.

The FC 302, and also the FC 301 in A1 enclosure, can
perform the safety function Safe Torque Off (STO, as
defined by EN IEC 61800-5-21) and Stop Category 0 (as
defined in EN 60204-12).
Danfoss has named this functionality Safe Stop. Prior to
integration and use of Safe Stop in an installation, a
thorough risk analysis on the installation must be carried
out in order to determine whether the Safe Stop
functionality and safety levels are appropriate and
sufficient. It is designed and approved suitable for the
requirements of :
-Safety Category 3 in EN 954-1 (and EN ISO
13849-1)
-Performance Level "d" in EN ISO 13849-1:2008
-SIL 2 Capability in IEC 61508 and EN 61800-5-2
-SILCL 2 in EN 62061

(STO) function.
2) Refer to EN IEC 60204-1 for details of stop category 0
and 1.
Activation and Termination of Safe Stop
The Safe Stop (STO) function is activated by removing the
voltage at Terminal 37 of the Safe Inverter. By connecting
the Safe Inverter to external safety devices providing a safe
delay, an installation for a safe Stop Category 1 can be
obtained. The Safe Stop function of FC 302 can be used for
asynchronous, synchronous motors and permanent
magnet motors. See examples in 3.8.1 Terminal 37 Safe StopFunction.

Terminal 37 Safe Stop Function
The FC 302 and FC 301 (optional for A1 enclosure) is
available with safe stop functionality via control terminal
37. Safe stop disables the control voltage of the power
semiconductors of the frequency converter output stage
which in turn prevents generating the voltage required to
rotate the motor. When the Safe Stop (T37) is activated,
the frequency converter issues an alarm, trips the unit, and
coasts the motor to a stop. Manual restart is required. The
safe stop function can be used for stopping the frequency
converter in emergency stop situations. In the normal
operating mode when safe stop is not required, use the
frequency converter’s regular stop function instead. When
automatic restart is used – the requirements according to
ISO 12100-2 paragraph 5.3.2.5 must be fulfilled.

If a running frequency converter is stopped by
using the function, the unit will trip and stop by
coasting. If this is not acceptable, e.g. causes
danger, the frequency converter and machinery
must be stopped using the appropriate stopping
mode before using this function. Depending on
the application a mechanical brake may be
required.
Concerning synchronous and permanent magnet

(EN 60204-1) with Safety Cat. 3 (EN 954-1) / PL “d” (ISO 13849-1)
or SIL 2 (EN 62061).
Safe Stop Commissioning Test
After installation and before first operation, perform a
commissioning test of the installation making use of safe
stop. Moreover, perform the test after each modification of
the installation.
Example with STO
A safety relay evaluates the E-Stop button signals and
triggers an STO function on the frequency converter in the
event of an activation of the E-Stop button (See
Illustration 3.18). This safety function corresponds to a
category 0 stop (uncontrolled stop) in accordance with IEC
60204-1. If the function is triggered during operation, the
motor will run down in an uncontrolled manner. The
power to the motor is safely removed, so that no further
movement is possible. It is not necessary to monitor plant
at a standstill. If an external force effect is to be
anticipated, additional measures should be provided to
safely prevent any potential movement (e.g. mechanical
brakes).
Example with SS1
SS1 correspond to a controlled stop, stop category 1
according to IEC 60204-1 (see Illustration 3.19). When
activating the safety function a normal controlled stop will
be performed. This can be activated through terminal 27.
After the safe delay time has expired on the external safety
module, the STO will be triggered and terminal 37 will be
set low. Ramp down will be performed as configured in
the drive. If drive is not stopped after the safe delay time
the activation of STO will coast the frequency converter.
NOTE
When using the SS1 function, the brake ramp of the drive
is not monitored with respect to safety.
Example with Category 4/PL e application
Where the safety control system design requires two
channels for the STO function to achieve Category 4 / PL e,
one channel can be implemented by Safe Stop T37 (STO)
and the other by a contactor, which may be connected in
either the drive input or output power circuits and
controlled by the Safety relay (see Illustration 3.20). The
contactor must be monitored through an auxiliary guided
contact, and connected to the reset input of the Safety
Relay.
Paralleling of Safe Stop input the one Safety Relay
Safe Stop inputs T37 (STO) may be connected directly
together if it is required to control multiple drives from the
same control line via one Safety Relay (see Illustration 3.21).
Connecting inputs together increases the probability of a
fault in the unsafe direction, since a fault in one drive
might result in all drives becoming enabled. The
probability of a fault for T37 is so low, that the resulting
probability still meets the requirements for SIL2.
Illustration 3.18 STO example
NOTE
For all applications with Safe Stop it is important that short
circuit in the wiring to T37 can be excluded. This can be
done as described in EN ISO 13849-2 D4 by the use of
protected wiring, (shielded or segregated).

WARNING
Safe Stop activation (i.e. removal of 24V DC voltage supply
to terminal 37) does not provide electrical safety. The Safe
Stop function itself is therefore not sufficient to implement
the Emergency-Off function as defined by EN 60204-1.
Emergency-Off requires measures of electrical isolation, e.g.
by switching off mains via an additional contactor.
1.Activate the Safe Stop function by removing the
24V DC voltage supply to the terminal 37.
2.After activation of Safe Stop (i.e. after the
response time), the frequency converter coasts
(stops creating a rotational field in the motor).
The response time is typically shorter than 10ms
for the complete performance range of FC 302.
The frequency converter is guaranteed not to restart
creation of a rotational field by an internal fault (in
accordance with Cat. 3 of EN 954-1, PL d acc. EN ISO
13849-1 and SIL 2 acc. EN 62061). After activation of Safe
Stop, the FC 302 display will show the text Safe Stop
activated. The associated help text says "Safe Stop has
been activated. This means that the Safe Stop has been
activated, or that normal operation has not been resumed
yet after Safe Stop activation.

The requirements of Cat. 3 (EN 954-1)/PL “d” (ISO 13849-1)
are only fulfilled while 24V DC supply to terminal 37 is
kept removed or low by a safety device which itself fulfills
Cat. 3 (EN 954-1) / PL “d” (ISO 13849-1). If external forces
act on the motor e.g. in case of vertical axis (suspended
loads) - and an unwanted movement, for example caused
by gravity, could cause a hazard, the motor must not be
operated without additional measures for fall protection.
E.g. mechanical brakes must be installed additionally.
In order to resume operation after activation of Safe Stop,
first 24V DC voltage must be reapplied to terminal 37 (text
Safe Stop activated is still displayed), second a Reset signal
must be created (via bus, Digital I/O, or [Reset] key on
inverter).
By default the Safe Stop functions is set to an Unintended
Restart Prevention behaviour. This means, in order to
terminate Safe Stop and resume normal operation, first the
24V DC must be reapplied to Terminal 37. Subsequently, a
reset signal must be given (via Bus, Digital I/O, or [Reset]
key).
The Safe Stop function can be set to an Automatic Restart
behaviour by setting the value of 5-19 Terminal 37 SafeStop from default value [1] to value [3]. If a MCB 112
Option is connected to the drive, then Automatic Restart
Behaviour is set by values [7] and [8].

3.12.2 Installation of External Safety Device
If the Ex-certified thermistor module MCB 112, which uses
Terminal 37 as its safety-related switch-off channel, is
connected, then the output X44/12 of MCB 112 must be
AND-ed with the safety-related sensor (such as emergency
stop button, safety-guard switch, etc.) that activates Safe
Stop. This means that the output to Safe Stop terminal 37
is HIGH (24V) only if both the signal from MCB 112 output
X44/12 and the signal from the safety-related sensor are
HIGH. If at least one of the two signals is LOW, then the
output to Terminal 37 must be LOW, too. The safety device
with this AND logic itself must conform to IEC 61508, SIL 2.
The connection from the output of the safety device with
safe AND logic to Safe Stop terminal 37 must be shortcircuit protected. See Illustration 3.22.

activated. In particular, paragraph 5.3.2.5 of ISO
12100-2 2003 must be observed
in Combination with MCB 112
Illustration 3.22 Illustration of the essential aspects for installing
a combination of a Safe Stop application and a MCB 112
application. The diagram shows a Restart input for the external
Safety Device. This means that in this installation 5-19 Terminal37 Safe Stop might be set to value [7] or [8]. Refer to MCB 112
operating instuctions, MG.33.VX.YY for further details.
Parameter settings for external safety device in
combination with MCB112
If MCB 112 is connected, then additional selections ([4] –
[9]) become possible for par. 5-19 (Terminal 37 Safe Stop).
Selection [1]* and [3] are still available but are not to be
used as those are for installations without MCB 112 or any
external safety devices. If [1]* or [3] should be chosen by
mistake and MCB 112 is triggered, then the frequency
converter will react with an alarm ”Dangerous Failure
[A72]” and coast the drive safely, without Automatic
Restart. Selections [4] and [5] are not to be selected when
an external safety device is used. Those selections are for
when only MCB 112 uses the Safe Stop. If selections [4] or
[5] are chosen by mistake and the external safety device
triggers Safe Stop then the frequency converter will react
with an alarm ”Dangerous Failure [A72]” and coast the
drive safely, without Automatic Restart.
Selections [6] – [9] must be chosen for the combination of
external safety device and MCB 112.

NOTE
Note that selection [7] and [8] opens up for Automatic
restart when the external safety device is de-activated
again.
This is only allowed in the following cases:
1.The Unintended Restart Prevention is
implemented by other parts of the Safe Stop
installation.
2.A presence in the dangerous zone can be
physically excluded when Safe Stop is not
activated. In particular, paragraph 5.3.2.5 of ISO
12100-2 2003 must be observed.
See10.6 MCB 112 PTC Thermistor Card and the operating
instructions for the MCB 112 for further information.
3.12.3
After installation and before first operation, perform a
commissioning test of an installation or application making
use of FC 300 Safe Stop.
Moreover, perform the test after each modification of the
installation or application, which the FC 300 Safe Stop is
part of.
Safe Stop Commissioning Test
1.4 Send Reset signal (via Bus, Digital I/O, or
[Reset] key). The test step is passed if the motor
becomes operational again.
The commissioning test is passed if all four test steps 1.1,
1.2, 1.3 and 1.4 are passed.
Case 2: Automatic Restart of Safe Stop is wanted and
allowed (i.e. Safe Stop only where 5-19 Terminal 37 SafeStop is set to [3], or combined Safe Stop and MCB112
where 5-19 Terminal 37 Safe Stop is set to [7] or [8]):
2.1 Remove the 24V DC voltage supply to
terminal 37 by the interrupt device while the
motor is driven by the FC 302 (i.e. mains supply is
not interrupted). The test step is passed if the
motor reacts with a coast and the mechanical
brake (if connected) is activated, and if an LCP is
mounted, the warning “Safe Stop [W68]” is
displayed.
2.2 Reapply 24V DC to terminal 37.
The test step is passed if the motor becomes operational
again. The commissioning test is passed if all two test
steps 2.1 and 2.2 are passed.
NOTE
See warning on the restart behaviour in 3.8.1 Terminal 37

NOTE
A passed commissioning test is mandatory after first installation and after each change to the safety installation.
The commissioning test (select one of cases 1 or 2 as
applicable):
Case 1: restart prevention for Safe Stop is required (i.e.
Safe Stop only where 5-19 Terminal 37 Safe Stop is set to
default value [1], or combined Safe Stop and MCB112
where 5-19 Terminal 37 Safe Stop is set to [6] or [9]):
1.1 Remove the 24V DC voltage supply to
terminal 37 by the interrupt device while the
motor is driven by the FC 302 (i.e. mains supply is
not interrupted). The test step is passed if the
motor reacts with a coast and the mechanical
brake (if connected) is activated, and if an LCP is
mounted, the alarm “Safe Stop [A68]” is
displayed.
1.2 Send Reset signal (via Bus, Digital I/O, or
[Reset] key). The test step is passed if the motor
remains in the Safe Stop state, and the
mechanical brake (if connected) remains
activated.
1.3 Reapply 24V DC to terminal 37. The test step
is passed if the motor remains in the coasted
state, and the mechanical brake (if connected)
remains activated.
NOTE
The Safe Stop function of FC 302 can be used for
asynchronous, synchronous and permanent magnet
motors. It may happen that two faults occur in the
frequency converter's power semiconductor. When using
synchronous or permanent magnet motors this may cause
a residual rotation. The rotation can be calculated to
Angle=360/(Number of Poles). The application using
synchronous or permanent magnet motors must take this
into consideration and ensure that this is not a safety
critical issue. This situation is not relevant for asynchronous
motors.

Efficiency
For fuse ratings, see 8.3.1 Fuses
1) High overload = 160% torque during 60 sec., Normal overload = 110% torque during 60 sec.
2) American Wire Gauge.
3) Measured using 5 m screened motor cables at rated load and rated frequency.
4) The typical power loss is at nominal load conditions and expected to be within +/-15% (tolerence relates to variety in voltage and
cable conditions).
Values are based on a typical motor efficiency (eff2/eff3 border line). Motors with lower efficiency will also add to the power loss in the
frequency converter and opposite.
If the switching frequency is increased compared to the default setting, the power losses may rise significantly.
LCP and typical control card power consumptions are included. Further options and customer load may add up to 30W to the losses.
(Though typical only 4W extra for a fully loaded control card, or options for slot A or slot B, each).
Although measurements are made with state of the art equipment, some measurement inaccuracy must be allowed for (+/-5%).
5) The three values for the max. cable cross section are for single core, flexible wire and flexible wire with sleeve, respectively.

1) For type of fuse see section Fuses.
2) American Wire Gauge.
3) Measured using 5 m screened motor cables at rated load and rated frequency.
4) The typical power loss is at nominal load conditions and expected to be within +/-15% (tolerence relates to
variety in voltage and cable conditions).
Values are based on a typical motor efficiency (eff2/eff3 border line). Motors with lower efficiency will also add to
the power loss in the frequency converter and opposite.
If the switching frequency is increased compared to the default setting, the power losses may rise significantly.
LCP and typical control card power consumptions are included. Further options and customer load may add up to
30W to the losses. (Though typical only 4W extra for a fully loaded control card, or options for slot A or slot B,
each).
Although measurements are made with state of the art equipment, some measurement inaccuracy must be
allowed for (+/-5%).

Mains voltage low / mains drop-out:
During low mains voltage or a mains drop-out, the FC continues until the intermediate circuit voltage drops below the minimum
stop level, which corresponds typically to 15% below the frequency converter's lowest rated supply voltage. Power-up and full
torque cannot be expected at mains voltage lower than 10% below the frequency converter's lowest rated supply voltage.

Protection and Features:
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches a
•
predefined level. An overload temperature cannot be reset until the temperature of the heatsink is below the
44
values stated in the tables on the following pages (Guideline - these temperatures may vary for different power
sizes, frame sizes, enclosure ratings etc.).
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
•
voltage is too low or too high.
The frequency converter constantly checks for critical levels of internal temperature, load current, high voltage on
•
the intermediate circuit and low motor speeds. As a response to a critical level, the frequency converter can adjust
the switching frequency and/ or change the switching pattern in order to ensure the performance of the
frequency converter.

When using a contactor with a DC coil inside in combination with Safe Stop, it is important to make a return way for the
current from the coil when turning it off. This can be done by using a freewheel diode (or, alternatively, a 30 or 50V MOV for
quicker response time) across the coil. Typical contactors can be bought with this diode.

4.6.1 Efficiency
In small motors, the influence from the U/f characteristic
on efficiency is marginal. However, in motors from 11kW
Efficiency of the frequency converter (η
VLT
)
and up, the advantages are significant.
The load on the frequency converter has little effect on its
efficiency. In general, the efficiency is the same at the
rated motor frequency f
, even if the motor supplies
M,N
100% of the rated shaft torque or only 75%, i.e. in case of
part loads.
In general, the switching frequency does not affect the
efficiency of small motors. Motors from 11kW and up have
their efficiency improved (1-2%). This is because the sine
shape of the motor current is almost perfect at high
switching frequency.
44
This also means that the efficiency of the frequency
converter does not change even if other U/f characteristics
are chosen.
However, the U/f characteristics influence the efficiency of
the motor.
The efficiency declines a little when the switching
frequency is set to a value of above 5 kHz. The efficiency
will also be slightly reduced if the mains voltage is 480V,
or if the motor cable is longer than 30m.
Frequency converter efficiency calculation
Calculate the efficiency of the frequency converter at
different loads based on Illustration 4.1. The factor in this
graph must be multiplied with the specific efficiency factor
listed in the specification tables:
Efficiency of the system (η

)
To calculate the system efficiency, the efficiency of the
frequency converter (η
the motor (η
η

4.7.1

Acoustic Noise
) is multiplied by the efficiency of
VLT
):
The acoustic noise from the frequency converter comes
from three sources:
1.DC intermediate circuit coils.
2.Integral fan.
3.RFI filter choke.
The typical values measured at a distance of 1 m from the
unit:
Illustration 4.1 Typical Efficiency Curves
Example: Assume a 55kW, 380-480V AC frequency
converter at 25% load at 50% speed. The graph is showing
0,97 - rated efficiency for a 55kW FC is 0.98. The actual
efficiency is then: 0.97x0.98=0.95.
Efficiency of the motor (η
MOTOR
)
The efficiency of a motor connected to the frequency
converter depends on magnetizing level. In general, the
efficiency is just as good as with mains operation. The
efficiency of the motor depends on the type of motor.
In the range of 75-100% of the rated torque, the efficiency
of the motor is practically constant, both when it is
controlled by the frequency converter and when it runs
directly on mains.

4.8.1 du/dt Conditions
NOTE
380-690V
To avoid premature ageing of motors (without phase
insulation paper or other insulation reinforcement) not
designed for frequency converter operation, Danfoss
strongly recommend to fit a du/dt filter or a Sine-Wave
filter on the output of the frequency converter. For further
information about du/dt and Sine-Wave filters see the
Output Filters Design Guide - MG.90.NY.XX.
When a transistor in the inverter bridge switches, the
voltage across the motor increases by a du/dt ratio
depending on:
-the motor cable (type, cross-section, length
screened or unscreened)
-inductance
The natural induction causes an overshoot U
motor voltage before it stabilises itself at a level
depending on the voltage in the intermediate circuit. The
rise time and the peak voltage U
affect the service life
PEAK
of the motor. If the peak voltage is too high, especially
motors without phase coil insulation are affected. If the
motor cable is short (a few metres), the rise time and peak
voltage are lower.
If the motor cable is long (100m), the rise time and peak
voltage are higher.
Peak voltage on the motor terminals is caused by the
switching of the IGBTs. The FC 300 complies with the
demands of IEC 60034-25 regarding motors designed to be
controlled by frequency converters. The FC 300 also
complies with IEC 60034-17 regarding Norm motors
controlled by frequency converters

4.9 Special Conditions
Under some special conditions, where the operation of the
drive is challenged, derating must be taken into account.
In some conditions, derating must be done manually.
In other conditions, the drive automatically performs a
degree of derating when necessary. This is done in order
to ensure the performance at critical stages where the
alternative could be a trip.
44
4.9.1 Manual Derating
Manual derating must be considered for:
Air pressure – relevant for installation at altitudes
•
above 1km
Motor speed – at continuous operation at low
•
RPM in constant torque applications
Ambient temperature – relevant for ambient
•
temperatures above 50°C
See application note MN.33.FX.YY for tables and
elaboration. Only the case of running at low motor speeds
is elaborated here.
4.6.1.1
When a motor is connected to a frequency converter, it is
necessary to check that the cooling of the motor is
adequate.
The level of heating depends on the load on the motor, as
well as the operating speed and time.
Constant torque applications (CT mode)
A problem may occur at low RPM values in constant
torque applications. In a constant torque application s a
motor may over-heat at low speeds due to less cooling air
from the motor integral fan.
Therefore, if the motor is to be run continuously at an RPM
value lower than half of the rated value, the motor must
be supplied with additional air-cooling (or a motor
designed for this type of operation may be used).
An alternative is to reduce the load level of the motor by
choosing a larger motor. However, the design of the
frequency converter puts a limit to the motor size.
Variable (Quadratic) torque applications (VT)
In VT applications such as centrifugal pumps and fans,
where the torque is proportional to the square of the
speed and the power is proportional to the cube of the
speed, there is no need for additional cooling or de-rating
of the motor.
In the graphs shown below, the typical VT curve is below
the maximum torque with de-rating and maximum torque
with forced cooling at all speeds.
94MG.33.BD.02 - VLT® is a registered Danfoss trademark
Derating for Running at Low Speed
Maximum load for a standard motor at 40 °C driven by a
frequency converter type VLT FCxxx
Legend: ─ ─ ─ ─Typical torque at VT load ─•─•─•─ Max torque
with forced cooling ‒‒‒‒‒Max torque
Note 1) Over-syncronous speed operation will result in the
available motor torque decreasing inversely proportional with
the increase in speed. This must be considered during the
design phase to avoid over-loading of the motor.
4.9.2 Automatic Derating
The drive constantly checks for critical levels:
Critical high temperature on the control card or
•
heatsink
High motor load
•
High DC link voltage
•
Low motor speed
•
As a response to a critical level, the frequency converter
adjusts the switching frequency. For critical high internal
temperatures and low motor speed, the drive can also
force the PWM pattern to SFAVM.
NOTE
The automatic derating is different when par. 14-55 Output
Filter is set to [2] Sine-Wave Filter Fixed.
