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


Pumps

• Minimized hydraulic shocks

in pipelines during start and

stop.

• Minimized mechanical stress

on motor shaft.

• Reduced starting current.

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


• 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.

Remote ControlRemote circuits connected to the MCD 3000 control inputs can be used

to operate the starter when in remote control mode.

Serial CommunicationThe RS485 serial link can be used to control operation when the starter

is either local or remote modes.

Restart DelayRestart Delay sets a minimum time between the end of a stop and the

beginning of the next start. During this period the LED to the right of

the numeric display will flash, indicating the motor cannot be started.

Local Control PanelThe Local Control Panel can be used to operate the MCD 3000 when in

local control mode.

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.

VentilationMCD 3000 cooling is by means of air circulation. Consequently, the air

needs to be able to move freely above and below the soft starter.

Soft starters dissipate approximately 4.5 watts per amp. When installing

a soft starter in a control panel or other enclosure, ensure there is

sufficient airflow through the enclosure to limit heat rise in the

enclosure.

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.
