WA RN IN G

PROPER GROUNDING

It is the responsibility of the installer of the soft starter to provide proper grounding and branch circuit protection according to local electrical safety codes. Not providing proper grounding and branch circuit protection may lead to death, personal injury, or equipment damage.

Disconnect the soft starter from mains voltage before carrying out repair work.

WA RN IN G

UNINTENDED START

When the soft starter is connected to AC mains, DC supply, or load sharing, the motor can start at any time. Unintended start during programming, service, or repair work can result in death, serious injury or property damage. The motor can start with an external switch, a fieldbus command, an input reference signal from the LCP, or after a cleared fault condition.

Press [Off/Reset] on the LCP before programming parameters.

Disconnect the soft starter from the mains.

Completely wire and assemble the soft starter, motor, and any driven equipment before connecting the soft starter to AC

mains, DC supply, or load sharing.

Fit the power supply to the soft starter with an isolating switch and a circuit-breaking device (for example a power

contactor) controllable through an external safety system (for example an emergency stop or a fault detector).

Safety

CA UT IO N

POWER FACTOR CORRECTION

Connecting power factor correction capacitors to the output side will damage the soft starter.

Do not connect power factor correction capacitors to the output of the soft starter. If static power factor correction is

employed, it must be connected to the supply side of the soft starter.

CA UT IO N

SHORT CIRCUIT

The VLT® Soft Starter MCD 600 is not circuit proof.

After severe overload or short circuit, the operation of the MCD 600 should be fully tested by an authorized service agent.

CA UT IO N

MECHANICAL DAMAGE FROM UNEXPECTED RESTART

The motor could restart after the causes of a shutdown are rectified, which may be dangerous for certain machines or installations.

Ensure that appropriate arrangements are made against restarting after unscheduled stops of the motor.

AQ262141844215en-000202 / 175R1174

Operating Guide | VLT® Soft Starter MCD 600

WA RN IN G

SAFETY OF PERSONNEL

The soft starter is not a safety device and does not provide electrical isolation or disconnection from the supply.

If isolation is required, the soft starter must be installed with a main contactor.

Do not rely on the start and stop functions for safety of personnel. Faults occurring in the mains supply, the motor

connection, or the electronics of the soft starter can cause motor starts or stops.

If faults occur in the electronics of the soft starter, a stopped motor may start. A temporary fault in the mains supply or loss

of motor connection can also cause a stopped motor to start.

To provide safety of personnel and equipment, control the isolation device through an external safety system.

NO TI CE

Before changing any parameter settings, save the current parameter set to a file using MCD PC Software or the Save User

Set function.

Safety

NO TI CE

Use the Auto-start feature with caution. Read all the notes related to auto-start before operation.

3.3 Selection of Soft Starter Size

The size of the soft starter must match the motor and the application.

Select a soft starter that has a current rating at least equal to the motor's full load current rating (see motor nameplate) at the start duty.

The soft starter's current rating determines the maximum motor size it can be used with. The soft starter's rating depends on the number of starts per hour, the length and current level of the start, and the amount of time the soft starter is off (not passing current) between starts.

The soft starter's current rating is only valid when used in the conditions specified in the AC53b code. The soft starter may have a higher or lower current rating in different operating conditions.

3.4 Current Ratings (IEC Ratings)

NO TI CE

Contact the local supplier for ratings under operating conditions not covered by these rating charts.

To format the flash, follow the instructions on a PC when connecting a standard flash stick (minimum 4 MB) to a USB port. VLT® Motion Control Tool MCT 10 transfers the set-up files to the USB flash stick. To load the set-up files to the soft starter, use the LCP as described in 6.7.1 Save

and Load Procedure.

The VLT® Motion Control Tool MCT 10 can help manage the soft starter. Contact the local supplier for more information.

Documentation for the VLT® Motion Control Tool MCT 10 can be downloaded from www.danfoss.com/en/search/?filter=type %3Adocumentation.

3.8 Main Contactor

A main contactor is recommended to protect the soft starter from voltage disturbances on the network while stopped. Select a contactor with an AC3 rating greater than or equal to the FLC rating of the connected motor.

SHOCK HAZARD

When the soft starter is wired in inside delta configuration, it results in a portion of the motor windings being connected to line power at all times (even when the soft starter is switched off). This situation may cause death or serious personal injury.

Always install a main contactor or shunt trip circuit breaker when connecting the soft starter in inside delta configuration.

3.9 Circuit Breaker

A shunt trip circuit breaker may be used instead of a main contactor to isolate the motor circuit if a soft starter trips. The shunt trip mechanism must be powered from the supply side of the circuit breaker or from a separate control supply.

3.10 Power Factor Correction

If power factor correction is used, use a dedicated contactor to switch in the capacitors.

To use the VLT® Soft Starter MCD 600 to control power factor correction, connect the PFC contactor to a programmable relay set to Run. When the motor reaches full speed, the relay closes and power factor correction is switched in.

EQUIPMENT DAMAGE

Connecting power factor correction capacitors to the output side damages the soft starter.

Always connect power factor correction capacitors to the input side of the soft starter.

Do not use the soft starter relay output to switch in power factor correction directly.

3.11 Short-circuit Protection Devices

When designing motor circuit protection schemes, the IEC 60947-4-1 standard on soft starters and contactors defines 2 types of coordination regarding soft starters:

• Type 1 coordination.

• Type 2 coordination.

3.11.1 Type 1 Coordination

Type 1 coordination requires that, if there is a short circuit on the output side of a soft starter, the fault must be cleared without risk of injury to personnel and damage to installations. There is no requirement that the soft starter must remain operational after the fault. For the soft starter to become operational again, repair and replacement of parts are required.

HRC fuses (such as Ferraz/Mersen AJT fuses) can be used for Type 1 coordination according to the IEC 60947-4-2 standard.

3.11.2 Type 2 Coordination

Type 2 coordination requires that, if there is a short circuit on the output side of a soft starter, the fault must be cleared without risk of injury to personnel or damage to the soft starter.

Type 2 coordination has the advantage that, after the fault is cleared, authorized personnel can replace the blown fuses and check contactors for any welding. The soft starter is then operational again.

Semiconductor fuses for Type 2 circuit protection are extra to HRC fuses or MCCBs that form part of the motor branch circuit protection.

CA UT IO N

DC BRAKE

A high brake torque setting can result in peak currents up to motor DOL being drawn while the motor is stopping.

Ensure that protection fuses installed in the motor branch circuit are selected appropriately.

CA UT IO N

NO BRANCH CIRCUIT PROTECTION

Integral solid-state short-circuit protection does not provide branch circuit protection.

Provide branch circuit protection in accordance with the National Electrical Code and any additional local codes.

3.12 IEC Coordination with Short-circuit Protection Devices

These fuses were selected based on a start current of 300% FLC for 10 s.

• The MCD 600 accepts stop commands from the designated command source, but can be forced to stop by opening the reset input, or by opening the start/stop input during an auto-start/stop cycle.

• The programmable input can be used to override the selected command source (see parameter 7-1 Input A Function).

9.2 Command Override

The programmable input (DI-A, COM+) can be used to override the command source for situations where the normal control mechanism has been lost. Set parameter 7-1 Input A Function to the alternative control source (for example Command Override: Keypad).

While the input is active, the soft starter only accepts commands from the selected override source. To restore control to the command source selected in parameter 1-1 Command Source, reopen the input.

9.3 Auto-start/Stop

The soft starter can be configured to automatically start and/or stop the motor at a particular time, or run it in cycles of a specified duration.

NO TI CE

Start delay, restart delay, and auto-reset delay all apply to auto-start operation.

9.3.1 Clock Mode

The soft starter can start and/or stop the motor once per day.

For clock mode to operate:

• Parameter 4-1 Auto-Start/Stop Mode must be set to Enable.

• Parameter 1-1 Command Source must be set to Clock.

• The reset input must be closed.

• The start input (START, COM+) must be active. This allows the soft starter to be stopped via the digital inputs in an emergency.

Clock mode operation is controlled by parameters 4-4 to 4-24.

9.3.2 Timer Mode

The soft starter can automatically stop the motor after a specified run-time, then restart it after a specified off (stopped) time. The soft starter repeats the cycle while the start signal remains active.

For timer mode to operate:

AQ262141844215en-000202 / 175R1174

Operating Guide | VLT® Soft Starter MCD 600

• Parameter 4-1 Auto-Start/Stop Mode must be set to Enable.

• Parameter 1-1 Command Source must be set to Timer.

• The reset input must be closed.

• The first start must be commanded by a start signal.

Timer mode operation is controlled by parameters 4-2 to 4-3.

Operation

9.4 PowerThrough

PowerThrough allows the soft starter to control the motor even if the soft starter is damaged on 1 phase. The VLT® Soft Starter MCD 600 uses 2-phase control techniques to soft start and soft stop the motor.

NO TI CE

The soft starter trips on Lx-Tx Shorted on the first start attempt after control power is applied. PowerThrough does not operate if control power is cycled between starts.

• PowerThrough is only available with in-line installations. If the soft starter is installed inside delta, PowerThrough will not operate.

• PowerThrough remains active until 3-Phase Control Only is reselected. While operating in PowerThrough, the trip LED flashes and the display indicates 2 Phase - Damaged SCR.

• PowerThrough operation does not support adaptive control soft starting or soft stopping. In PowerThrough, the soft starter automatically selects constant current soft starting and timed voltage ramp soft stopping. If PowerThrough is enabled, Parameters 2-3 and 2-4 must be set appropriately.

NO TI CE

PowerThrough uses a 2-phase soft start technology and extra care is required when sizing circuit breakers and protection. Contact the local supplier for assistance.

9.5 Emergency Mode

Emergency mode allows the soft starter to run the motor and ignore trip conditions.

Emergency mode is controlled via a programmable input (input A DI-A, COM+ or input B DI-B, COM+). Parameter 7-1 Input A Function/ parameter 7-5 Input B Function must be set to Emergency Mode. A closed circuit across DI-A, COM+ activates emergency mode. When the soft starter receives a start command, it continues to run until a stop command is received, ignoring all trips and warnings.

Emergency mode can be used with any command source.

NO TI CE

Although emergency mode operation satisfies the functionality requirements of fire mode, Danfoss does not recommend its use in situations that require testing and/or compliance with specific standards as it is not certified.

Operation

NO TI CE

REDUCED EQUIPMENT LIFETIME

Continued use of emergency mode is not recommended. Emergency mode may compromise the soft starter and/or motor life as all protections and trips are disabled. Using the soft starter in emergency mode voids the product warranty.

Do not run the soft starter in emergency mode continuously.

9.6 Auxiliary Trip

An external trip circuit (such as a low-pressure alarm switch for a pumping system) can be used to trip the soft starter and stop the motor. The external circuit is connected to a programmable input (input A DI-A, COM+ or input B DI-B, COM+). To control the behavior of the trip, set the following parameters:

• Parameter 7-1 Input A Function: Select Input Trip (N/O).

• Parameter 7-2 Input A Trip: Set as required. For example, Run Only limits the input trip to when the soft starter is running only.

• Parameter 7-3 Input A Trip Delay: Sets a delay between the input activating and the soft starter tripping.

• Parameter 7-4 Input A Initial Delay: Sets a delay before the soft starter monitors the state of the input after the start signal. For example, a delay may be required to allow time for pipeline pressure to build up.

• Parameter 7-10 Input A Name: Select a name, for example Input A Trip (optional).

9.8 Soft Start Methods

9.8.1 Constant Current

Constant current is the traditional form of soft starting, which raises the current from 0 to a specified level and keeps the current stable at that level until the motor has accelerated.

Constant current starting is ideal for applications where the start current must be kept below a particular level.

9.8.2 Constant Current with Current Ramp

Current ramp soft starting raises the current from a specified starting level (1) to a maximum limit (3) over an extended period (2).

Current ramp starting can be useful for applications where:

• The load can vary between starts (for example a conveyor which may start loaded or unloaded). Set parameter 2-3 Initial Current to a level that will start the motor with a light load. Then, set parameter 2-4 Current Limit to a level that will start the motor with a heavy load.

• The load breaks away easily, but starting time has to be extended (for example a centrifugal pump where pipeline pressure has to build up slowly).

• The electricity supply is limited (for example a generator set), and a slower application of load allows greater time for the supply to respond.

9.8.3 Adaptive Control for Starting

In an adaptive control soft start, the soft starter adjusts the current to start the motor within a specified time and using a selected acceleration profile.

NO TI CE

The soft starter applies the current limit on all soft starts, including adaptive control. If the current limit is too low or the start ramp time (set in parameter 2-2 Start Ramp Time) is too short, the motor may not start successfully.

Operating Guide | VLT® Soft Starter MCD 600

Operation

9.8.3.1 Fine-tuning Adaptive Control

If the motor does not start or stop smoothly, adjust parameter 2-12 Adaptive Control Gain. The gain setting determines how much the soft starter adjusts future adaptive control starts and stops, based on information from the previous start. The gain setting affects both starting and stopping performance.

• If the motor accelerates or decelerates too quickly at the end of a start or stop, increase the gain setting by 5–10%.

• If the motor speed fluctuates during starting or stopping, decrease the gain setting slightly.

NO TI CE

The soft starter tunes adaptive control to match the motor. Changing the following parameters resets adaptive control and the first start/stop cycle uses constant current start/timed voltage ramp stop: Parameter 1-2 Motor Full Load Current, parameter 2-4 Current Limit, and parameter 2-12 Adaptive Gain.

9.8.4 Constant Current with Kickstart

Kickstart provides a short boost of extra torque at the beginning of a start, and can be used with current ramp or constant current starting.

Kickstart can be useful to help start loads that require high breakaway torque but then accelerate easily (for example helical rotor pumps).

9.9 Stop Methods

9.9.1 Coast to Stop

Coast to stop lets the motor slow at its natural rate with no control from the soft starter. The time required to stop depends on the type of load.

9.9.2 Timed Voltage Ramp

Timed voltage ramp (TVR) reduces the voltage to the motor gradually over a defined time. This can extend the stopping time of the motor and may avoid transients on generator set supplies.

NO TI CE

The load may continue to run after the stop ramp is complete.

1 Parameter 2-10 Stop Time

Illustration 30: Example of TVR

9.9.3 Adaptive Control for Stopping

In an adaptive control soft stop, the soft starter controls the current to stop the motor within a specified time and uses a selected deceleration profile. Adaptive control can be useful in extending the stopping time of low inertia loads.

If adaptive control is selected, the first soft stop uses TVR. This allows the soft starter to learn the characteristics of the connected motor. This motor data is used by the soft starter during subsequent adaptive control stops.

Adaptive control does not actively slow the motor down and does not stop the motor faster than a coast to stop. To shorten the stopping time of high inertia loads, use brake.

Operation

NO TI CE

Adaptive control controls the motor's speed profile, within the programmed time limit. This may result in a higher level of current than traditional control methods.

If replacing a motor connected to a soft starter programmed for adaptive control starting or stopping, the soft starter has to learn the characteristics of the new motor. Change the value of parameter 1-2 Motor Full Load Current or parameter 2-12 Adaptive Control Gain to initiate the relearning process. The next start will use constant current and the next stop will use TVR.

Adaptive control is ideal for pumping applications where it can minimize the damaging effects of fluid hammer. Test the 3 profiles to identify the best profile for the application.

Adaptive stop profile Application

Late deceleration High-head systems where even a small decrease in motor/pump speed results in a rapid transition between

forward flow and reverse flow.

Constant deceleration Low to medium head, high-flow applications where the fluid has high momentum.

Early deceleration Open pump systems where fluid must drain back through the pump without driving the pump in reverse.

9.9.4 DC Brake

A brake reduces the time required to stop the motor.

During braking, an increased noise level from the motor may be audible. This is a normal part of motor braking.

NO TI CE

When using DC brake, the mains supply must be connected to the soft starter (input terminals L1, L2, and L3) in positive phase sequence.

MOTOR DAMAGE

If the brake torque setting is too high, the motor stops before the end of the brake time and the motor suffers unnecessary heating, which could result in damage. A high brake torque setting can also result in peak currents up to motor DOL being drawn while the motor is stopping.

Careful configuration is required to ensure safe operation of the soft starter and the motor.

Ensure that protection fuses installed in the motor branch circuit are selected appropriately.

NO TI CE

RISK OF OVERHEATING

Brake operation causes the motor to heat faster than the rate calculated by the motor thermal model.

Install a motor thermistor or allow sufficient restart delay (set in parameter 5-16 Restart Delay).

Operation

1 Parameter 2-10 Stop Time

2 Parameter 2-16 Brake Time

3 Coast to stop time

Illustration 32: Example of Brake Time

Parameter settings:

• Parameter 2-9 Stop Mode: Set to DC Brake.

• Parameter 2-10 Stop Time: This is the total braking time (1) and must be set sufficiently longer than the brake time (in parameter 2-16 DC Brake Time) to allow the prebraking stage to reduce motor speed to approximately 70%. If the stop time is too short, braking will not be successful and the motor will coast to stop.

• Parameter 2-15 DC Brake Torque: Set as required to slow the load. If set too low, the motor will not stop completely and will coast to stop after the end of the braking period.

• Parameter 2-16 DC Brake Time: Set this parameter to approximately 1 quarter of the programmed stop time. This sets the time for the full brake stage (2).

Operating Guide | VLT® Soft Starter MCD 600

Operation

9.9.5 DC Brake with External Zero-speed Sensor

For loads which may vary between braking cycles, install an external zero-speed sensor to ensure that the soft starter ends DC braking at motor standstill. Using a sensor prevents unnecessary motor heating.

Configure DC brake for the longest braking time required, and also set parameter 7-1 Input A Function to Zero Speed Sensor. When the motor reaches a standstill, the zero-speed sensor opens the circuit across DI-A, COM+ and the soft starter terminates the stop.

9.9.6 Soft Brake

For applications with high inertia and/or variable load requiring the maximum possible brake power, the soft starter can be configured for soft braking.

The soft starter uses a changeover relay to control forward run and braking contactors. While braking, the soft starter reverses the phase sequence to the motor and supplies reduced current, gently slowing the load.

When motor speed approaches 0, the zero-speed sensor (A2) stops the soft starter and opens the braking contactor (K2).

Soft braking can be used with both the primary and secondary motor sets and must be configured separately for each.

Parameter settings:

• Parameter 2-9 Stop Mode: Set to Soft Brake.

• Parameter 2-17 Brake Current Limit: Set as required to slow the load.

• Parameter 2-18 Soft Brake Delay: Controls the time the soft starter waits after a stop signal is received, before it begins to supply braking current to the motor. Set to allow time for K1 and K2 to switch.

• Parameter 7-1 Input A Function: Set to Zero Speed Sensor.

• Parameter 8-1 Relay A Function: Set to Soft Brake Relay.

9.10 Pump Clean

The soft starter can perform a pump clean function before soft starting the motor. This can help dislodge debris from the impeller.

Pump clean starts the motor in reverse then forward direction, then stops the motor. Pump clean can be configured to repeat the process up to 5 times. After the specified number of cleaning cycles, the soft starter performs the programmed soft start.

Pump clean operation is controlled by the start/stop input (START, COM+). Set a programmable input to pump clean (see parameter 7-1 Input A Function for details). Ensure that the input is closed when the start signal is applied.

Do not enable pump clean on pumps that cannot operate in reverse direction.

9.11 Reverse Direction Operation

The soft starter can control a reversing contactor to operate the motor in reverse direction. When reverse operation is selected, the soft starter performs a soft start using the opposite phase sequence from normal operation.

Reverse operation is controlled by the start/stop input (START, COM+). Set a programmable input to reverse direction (parameter 7-1 Input A Function) and set an output to reversing contactor (parameter 8-1 Relay A Function).

The input must be closed when the start signal is applied. The soft starter keeps the reverse relay in the same state until the end of the starting/stopping cycle.

NO TI CE

The first start after the direction is changed will be constant current.

If phase sequence protection is required, install the reversing contactor on the output (motor) side of the soft starter.

9.12 Jog Operation

Jog runs the motor at reduced speed to allow alignment of the load or to assist servicing. The motor can be jogged in either forward or reverse direction.

Jog is only available when the soft starter is controlled via the digital inputs (parameter 1-1 Command Source set to Digital Input). To operate in jog, set a programmable input to jog (see parameter 7-1 Input A Function for details). Ensure that the input is closed when the start signal is applied.

REDUCED MOTOR COOLING

Slow speed running is not intended for continuous operation due to reduced motor cooling. Jog operation causes the motor to heat faster than the rate calculated by the motor thermal model.

NO TI CE

Install a motor thermistor or allow sufficient restart delay (parameter 5-16 Restart Delay).

9.13 Inside Delta Operation

When connecting in inside delta, enter the value of the FLC in parameter 1-2 Motor Full Load Current. The soft starter automatically detects whether the motor is connected in-line or inside delta and calculates the correct inside delta current level.

Adaptive control, jog, brake, and PowerThrough functions are not supported with inside delta (6-wire) operation. If these functions are programmed when the soft starter is connected inside delta, the behavior is given as below.

Adaptive control start The soft starter performs a constant current start.

Adaptive control stop The soft starter performs a TVR soft stop if parameter 2-10 Stop Times is >0 s. If parameter 2-10 Stop Times is

Operation

NO TI CE

When connected in inside delta, the soft starter does not detect phase loss on T2 during run.

NO TI CE

If the soft starter is not correctly detecting the motor connection, use parameter 20-6 Motor Connection.

9.14 Secondary Motor Set

The soft starter can be programmed with 2 separate starting and stopping profiles. This allows the soft starter to control the motor in 2 different starting and stopping configurations. The secondary motor set is ideal for dual winding (Dahlander) motors, multi-motor applications, or situations where the motor may start in 2 different conditions (such as loaded and unloaded conveyors). The secondary motor set can also be used for duty/standby applications.

NO TI CE

For duty/standby applications, set parameter 6-17 Motor Overtemperature to Log Only and install temperature protection for each motor.

To use the secondary motor set, set a programmable input to Motor Set Select. The input must be closed when a start command is given (see parameter 7-1 Input A Function and parameter 7-5 Input B Function. The soft starter checks which motor set to use at start and uses that motor set for the entire start/stop cycle.

The soft starter uses the secondary motor settings to control a start when instructed via a programmable input (see parameter 7-1 Input A Function and parameter 7-5 Input B Function).

NO TI CE

The motor thermal model is less accurate if the soft starter controls 2 separate motors.
