MCD 3000 Soft Starter Overview
The perfect softener of rough startsAC motors often cause one or more serious problems during start-up
acceleration. These problems include:
• High starting current, often causing an unacceptable load on the
AC line.
• Shock load on gear and other transmission elements, causing
unnecessary wear on mechanical parts.
• Fast acceleration and deceleration, causing unstable process
conditions (e.g. in conveyors).
The Danfoss MCD 3000 Soft Starter is the optimum solution to all these
problems for AC motors ranging from 10-1,000 HP.

Limitations of Traditional StartersTraditionally, star/delta and auto transformer starters have been seen as
solutions to these problems. However, both these options have
drawbacks and do not solve the problems caused by wear of the
transmission elements and unstable process conditions.
The Star/Delta Starter
• Reduces start current but introduces a damaging torque transient
when switching from star to delta connection
• Does not allow selection of the best start current level. This
sometimes means the load cannot accelerate to full speed in star
connection, thereby making the star/delta starter ineffective
• Does not control the way the motor stops, thus leaving the speed to
ramp down without control
The Auto Transformer
• Reduces start current but also allows some control over the level of
start current. Auto transformer starters do not, however, eliminate
the risk of a surge in torque when shifting voltage
The MCD 3000 Soft Starter SolutionUnlike traditional solutions the MCD 3000 Soft Starter offers a wide
range of benefits for motor and equipment operation as a whole,
including:
• Flexible control of starting current and torque
• Smooth control of current and voltage without any steps or
transients
• Frequent start/stop operation without mechanical damage
• Flexibility to changes in the start conditions, increasing flexibility
in the application
• Soft stop control for extending the motor deceleration time
• Braking control to reduce motor deceleration time

MCD 3000 Features – Control
MCD 3000 electronic soft starters control motor current to provide a
smooth start. When is the MCD 3000 the correct fit for your application?
Anytime one or more of the following apply:
• High starting currents put an unacceptable load on the electrical
supply
• Rapid acceleration rates place stress on the driven equipment or slip
drive belts
• Utility regulations prohibit line-starting of motors
Adjustable Frequency Drives vs. Electronic Soft StartersJust like Danfoss adjustable frequency drives, the MCD 3000 provides the
latest in electronic, programmable, motor control.
The smooth, current-controlled acceleration provided by the soft
starter is the perfect fit for many applications. In more complex
applications, the soft starter may be used in conjunction with the
adjustable frequency drive’s bypass circuitry to provide smooth, reduced
current acceleration whenever the system is run in bypass.
Keypad Control and LED DisplayThe built-in local control panel and LED display allows setting of all
parameters, selection of local or remote operation, and monitoring of
motor current.
MCD 3000 is Fully Electronic and Fully controllableThe smooth, electronic, current-controlled starts provided by the MCD
3000 eliminate undesired torque pulsations and power line current
transients. The MCD 3000 provides smooth, controlled acceleration to a
degree not possible with wye/delta, auto transformer, or partial winding
motor starters.
The MCD 3000 uses three-phase, closed loop current control to
constantly monitor current. Current transducers continuously measure
the current supplied to the motor. A rugged, full-wave, fully-controlled
SCR bridge directly controls current to all three phases of the motor.
The fully interchangeable control card uses the current information
from the transducers to construct the ideal switching algorithms to
control the SCRs at all times, precisely maintaining the desired current,
controlling acceleration, and minimizing motor heating.
The user sets the desired acceleration current. The soft starter
smoothly accelerates the load to full speed. Current draw is minimized
and stress on the motor and driven equipment is reduced.
The MCD 3000 provides a wide range of control and protection
features, including:
• Overload protection for the motor
• Overload protection for the soft starter
• Adjustable calculated motor thermal protection
• Provision for a motor thermistor
• Overtemperature protection for the soft starter
• Phase imbalance protection
• Phase loss protection
• Phase rotation protection
• Undervoltage protection
• Selectable automatic or manual fault reset
• Line frequency monitoring to detect unstable operation of
emergency power generators
• A fault log for troubleshooting
Programmable Features• Three programmable relay outputs allow external indications of a
run command, presence of a fault, or of a broken belt (low current
warning)
• An auto restart time delay can be set
• Phase imbalance sensitivity can be set to eliminate nuisance faults
• Password protection locks the parameters from unauthorized
changes

MCD 3000 Features – Control
Working PrincipleMotor voltage is controlled by means of a phase cut principle. Two
thyristors in each phase perform the power switching, enabling the
starter to handle high starting torque and frequent starts/stops. Current
transformers measure the motor current providing feedback for
constant current control of motor starting, and also for numerous
motor and application protection functions.
Cabling
• AC line, motor and bypass connectors: Bar type with thread for
fastening bolts for cable shoes.
• Control cable connections: Terminal block for 0.14 m~1.5 m 2/
26~16 AWG.
• Control card supply connection: Terminal block for 2.5~4 mm2/
14~12 AWG.
• The bottom plates are removable and include a drilling template for
cable entries.
Short circuit protection
For proper protection semiconductor fuses must be installed in front of
the starter.
Control inputs
• Start/stop. Can be configured for either two-wire and pulse (three-
wire) start/stop commands.
• Reset.
• Parameter set. For selection between two unique motor parameter
sets.
Signal outputs
Three relay outputs (programmable) for control of:
• Line, Bypass and DC brake contactors.
• Run, Trip, Output on, and High/low current indication.
Bypass
If the soft starter is mounted in a cabinet without ventilation, a bypass
contactor should be applied to prevent heat dissipation during
operation. The starter has built in bars for connection of a bypass
contactor. This allows the MCD 3000 Soft Starter to measure motor
current and retain all motor protection functions even when the bypass
contactor is closed.
EMC
Compliant with the requirements in the product standard IEC 947-4-2,
AC semiconductor motor controllers and starters.
Power
• Supply voltage: 3x200-525 VAC Please specify voltage range at
ordering.
• Supply frequency: 50/60 Hz
• Control voltage: 110 V or 230 V (+10%/-15%)
• Other control voltages can be accommodated by fitting an optional
transformer within the starter.
• Ambient max temperature 60°C (for ambient temperature beyond
40°C — contact Danfoss)

MCD 3000 Features – Keypad and Parameter Functions
Programming the MCD 3000For simple applications the MCD 3000 needs only to be programmed
with the FLC (Full Load Current) of the connected motor.
To program the MCD 3000 with the motor FLC do the following:
1. Enter the programming mode by pressing the [Menu/Cancel]
button on the Local Control Panel. The display will show the
number of the first programming parameter, Par. 1 Motor FLC.
2. Press the [Change Data/OK] button to display the programmed
value. The setting may now be adjusted.
3. Using the [+/-] buttons adjust the setting to match the motor FLC.
4. When correct, store the Motor FLC setting by pressing the [Change
Data/OK] button. (Pressing the [Menu/Cancel] button returns you
to the parameter number without saving the new value).
5. Return the MCD 3000 to run mode by pressing the [Menu/Cancel]
button.

MCD 3000 Features – Programming
Secondary Parameter SetThe MCD 3000 has two motor parameter sets
• Primary Parameter Set: Par. 1 – 9
• Secondary Parameter Set: Par. 25 – 33
When the MCD 3000 is in the off state and is commanded to start, it
checks the Par. Set control input. If open circuit, the primary parameter
set is used. If closed circuit, the secondary parameter set is used.
Motor Thermal ModelThe MC 3000 motor overload protection is an advanced motor thermal
model. Motor temperature is continuously calculated by the
microprocessor that uses a sophisticated mathematical model to
accurately reflect motor heat generation and dissipation during all
stages of operation, e.g. Starting, Running, Stopping & Stopped.
Because it operates continuously, the motor thermal model
eliminates the need for protection systems such as: Excess Start Time,
Limited Starts per hour etc. The state of the motor thermal model can
be viewed on the numeric display while the MCD 3000 is not in
programming mode. Us the [+/-] keys to change the parameter shown
on the numeric display. Motor temperature is shown as a % of
maximum temperature. An overload trip occurs at 105%.
Pre-start TestsOn receiving a start command, MCD 3000 starters operate the Line
Contactor relay output (if programmed) and then perform a series of
tests before applying voltage to the motor terminals and operating the
Output On relay output (if programmed).
Operation after Power LossWhen control and supply voltage is applied to the MCD 3000 it will enter
either the local or remote mode according to the state it was in when
voltage was removed.
If in remote mode, the condition of the remote control inputs is
checked and if a start command is present the motor will be started.
If in local mode, the motor will not be restarted until the [Start]
push button is activated.

MCD 3000 Features – Protection and Easy Handling
The MCD 3000 Soft Starter is second-to-none when it comes to
compensating for the drawbacks of starting and stopping of AC motors.
In addition it offers the most comprehensive motor and application
protection on the market, including:
Motor ProtectionContinuous monitoring of motor load for calculating motor
temperature. The value is shown in the display as percentage of
maximum temperature, and the function is active even when the power
section is bypassed.
Phase Rotation ProtectionMany applications are sensitive to the direction of rotation of the motor.
With a standard motor starter, a change in phase rotation of the power
applied to the starter will cause the driven motor to reverse direction.
The MCD 3000 can be programmed to detect the phase rotation of the
applied three-phase power. If the phase rotation is changed, the MCD
3000 can trip and indicate a fault.
Application Protection• Undercurrent protection. Particularly useful for ensuring that
pumps do not run dry.
• Shear pin protection. Ensures detection of foreign bodies blocking
operation.
• Phase sequence protection. Prevents machinery from running in
reverse.
• Phase imbalance protection.
Completing the picture Danfoss has added a range of user-friendly
benefits to the MCD 3000 Soft Starter. Among them are:
Easy installation• MCD 3000 Soft Starter is wall mountable, offering ample space for
glanding and terminating the cables.
• Side-by-side mounting without clearance (larger sizes only require
4 inches of clearance).
• No optional equipment required to perform any tasks.
Easy operation• Only one parameter to adjust for basic operation.
• Only a few parameters to adjust for high level control and
protection.
• No need for field calibration to ensure correct operation. The MCD
3000 Soft Starter has a factory accuracy of +5% for current
measurement.
• Built-in local control panel with display.
• Quick set-up.
Bypass OperationThe soft-starter may be bypassed once the motor has reached rated
speed. The MCD 3000 will close an optional externally-mounted
contactor, transferring the motor to the line, reducing the heat
generated by the MCD 3000, maximizing system efficiency, and
minimizing electrical noise generation. The contactor wires run
through the MCD 3000 so that current is monitored and complete
motor overload protection is provided even when bypassed.

MCD 3000 Soft Starter SelectionMotor horsepower ratings are given for reference only. Soft starters must
always be sized for the full load current rating of the connected load.
Nominal current ratings given are the continuous full load current that
the soft starter can deliver.
The typical starter current ratings are based on:
• Max Operating Temperature 40° C
• Max Elevation 3000 Feet
• Max Number Of Starts Per Hour 10
• Minimum On Load Duty Cycle 50%
Example of starts per hour and on load duty cycle:
The starter starts 10 times an hour or once every 6 minutes. During that
6 minutes the starter runs at least 3 or more of those minutes, or at least
50% of the cycle time.
Many applications will not require as high of a cycle rate. If the
cycle rate were greater or the on load duty cycle shorter, the starter may
have to be oversized to handle the application.
The list at right shows the typical multipliers assigned to the full
load current requirements of various applications. Based on experience
the required start current ratings are given. For high inertia or heavy
load applications consult the factory for sizing assistance. Consult the
Operating Instructions manual for more application information.
Sizing software is also available on our web site:
http://danfossdrives.com/WinStart/passform.htm
This software provides you with the ability to enter application
information such as, starts per hour, load information, ramp time
required and environmental information. Once the information is
entered the software will automatically select the correct starter size.

The soft starter decreases the starting current by reducing, but
controlling the starting voltage. In doing so the available starting
torque available from the motor is also reduced. Typical starting torque
reductions are approximately the square of the current reduction
obtained from soft start control.

MCD 3000 Control Wiring
The MCD 3000 can be controlled using the local push buttons, or via
remote control inputs. Switch between the local and remote modes
using the [Local/Remote] push button.
The MCD 3000 has four remote control inputs. Contacts used for
controlling these inputs should be low voltage, low current rated (Gold
flash or similar). The Stop and Reset circuits must be closed for the
MCD 3000 to run in remote control mode.

MCD 3000 Features – Selection Overview
MCD Soft Starter Selection Guide and OrderingInformationWhen ordering, use the ordering number that corresponds to the
appropriate MCD 3000 model number.
Models MCD 3007 – 3132 are IP21 (NEMA 1) rated and have a local
control panel that includes start, stop & reset push buttons. They are
suitable for wall mounting or installation in a switchboard.
Models MCD 3185 – 3800 have an IP20 rating and must be installed in
a control panel or other enclosure. The MCD 3000 Soft Starters are
complete and require no optional modules to add functionality.
Automatic detection and calibration for supply voltage and frequency
eliminates the need for special models. MCD 3000 Soft Starters are
available with two maximum voltage ratings.
• 200 VAC – 525 VAC
• 200 VAC – 690 VAC
The power circuit uses reverse parallel connected thyristors to provide
full wave control on all three phases. The MCD 3000 can be used with
or, if local regulations permit, without a line contactor.
