Safety instructions
Safety
The softstarter should be installed in a cabinet or in an
electrical control room.
• The device must be installed by trained personnel.
• Disconnect all power sources before servicing.
• Always use standard commercial fuses, slow blow e.g. gl,
gG types, to protect the wiring and prevent short
circuiting. To protect the thyristors against short-circuit
currents, superfast semiconductor fuses can be used if
preferred. The normal guarantee is valid even if superfast
semiconductor fuses are not used.

2. Description
In this chapter different starting methods for induction
motors are explained and compared. The functionality of
softstarters with torque control and their advantages and
limitations compared to other starting methods are
explained.
First a brief account of the background theory of starting
induction motors will be given in section 2.1. Thereafter the
different starting methods based on the usage of reduced
voltage will be described and compared. This chapter will
also cover softstarters with torque control. In section 2.3
some common starting methods based on other physical
principles are explained. With this information some limita-
tions of the reduced voltage starters will become clear. In
section 2.4 there is a brief analysis of which applications may
benefit from using a softstarter.
2.1 Background theory
The following two sections deal with motors with squirrel-
cage rotors. In contrast to a wound rotor, the squirrel-cage
rotor consists of straight conductors, which are short-
circuited together at both ends.
When such a motor is connected directly to the line voltage
it will typically draw a starting current of about 5 to 8 times
its nominal current while the resulting starting torque will
be about 0.5 to 1.5 times its nominal torque. In the follow-
ing picture a typical starting characteristic is shown. The x-
axis represents the speed relative to the nominal speed while
the y-axis shows the torque and the current respectively, even
those normalized to their nominal values. The dashed line
indicates the nominal values.
Fig. 3 Typical torque characteristics for the DOL start
Fig. 4 Typical current characteristics for the DOL start
For many industrial applications direct on-line starting is
not convenient, as the supply in this case has to be dimen-
sioned to deliver the unnecessarily high starting current.
Moreover, most applications do not gain anything from the
high starting torque. Instead there is a risk of mechanical
wear or even damage because of the resulting jerk at spee-
dup.
The acceleration torque is determined by the difference
between motor and load torque. The figure below shows
some typical torque characteristics for constant speed appli-
cations. For comparative purposes, the inducion motors’
torque characteristic is added to the diagram.
Fig. 5 Typical load torque characteristics
Typical applications with constant load are elevators, cranes
and conveyors. Linear load characteristics are found for cal-
endar rollers and smoothing machines; quadratic correlation
between speed and torque is typical for pumps and fans.

10 Description Emotron AB 01-4135-01r1
Some applications like conveyors or screws may need an ini-
tial torque boost. However, for many applications it can be
seen that the torque needed is much lower than the torque
delivered by the induction motor in a DOL start.
A common method to reduce both starting torque and cur-
rent is to decrease the motor voltage during starting. The
following figure shows how the motor’s torque and current
characteristics are changed when the supply voltage is
reduced.
Fig. 6 Reduced voltage start
A general rule of thumb is that the torque at each operating
point is roughly proportional to the square of the current.
This means when the motor current is decreased by a factor
of two by means of reducing the supply voltage, the torque
delivered by the motor will be decreased by a factor of four
(approximately).
This relationship is the base for any starting method using
reduced voltage. It can be seen that the possibility of reduc-
ing the starting current depends on the correlation between
the motor’s and the load’s torque characteristic. For the com-
bination of an application with very low starting load and a
motor with very high starting torque, the starting current
may be reduced significantly by means of decreasing the
voltage during start. However, for applications with high
starting load it may – depending on the actual motor – not
be possible to reduce the starting current at all.
2.2 Reduced voltage starting
This section describes different starting methods which are
based on the reduced-voltage principle explained above. A
pump and its quadratic torque characteristic are used as an
example.
The star-delta starter is the simplest example of a reduced
voltage starter. The motor phases are first star connected; at
about 75% of nominal speed the phase connection is then
changed to delta. To enable star-delta start, both ends of all
three motor windings have to be available for connection.
Moreover, the motor has to be dimensioned for the (higher)
voltage in the delta connection. The following figure shows
the resulting torque and current characteristics.

Emotron AB 01-4135-01r1 Description 11
The disadvantage of the star-delta start is that it cannot be
adapted to a special application. Both the voltage in star and
in delta connection are defined by the supply, the resulting
starting performance depends on the motor’s DOL charac-
teristic. For some applications the star-delta starter cannot
be used as the resulting torque in star connection is too low
to start rotating the load. On the other hand for low load
applications further savings of starting current are impossi-
ble even though a big torque reserve is available. Moreover,
the resulting abrupt rise of torque first at start and later
when changing from star to delta connection may contrib-
ute to mechanical wear. The high transient currents during
start-delta transition create unnecessary excess heat in the
motor.
Better performance is achieved with a voltage ramp start,
which a simple electronic softstarter can provide. The volt-
age is increased linearly from an initial value to the full sup-
ply voltage by means of phase angle control. The resulting
torque and current characteristics are shown in the following
figure.
Fig. 8 Soft starting – voltage ramp
Obviously a much smoother start is realized compared to the
star-delta start and the starting current is decreased.
A softstarter i often used to keep the starting current below a
desired level. For the example above, setting a current limit
of three times the nominal current may be desirable. The
following figure shows the resulting torque and current char-
acteristics.
Fig. 9 Soft starting – voltage ramp with current limit
Once again the figure illustrates that the resulting perform-
ance depends on the combination of motor and load charac-
teristics. In the example above the motor torque is close to
the load torque at about half speed. This means for some
other applications with different load characteristics (for
example a linear torque-speed correlation) this particular
motor would need more than three times the nominal cur-
rent to start.
The most sophisticated electronic softstarters use torque
control, which results in an almost constant acceleration
during the start. A low starting current is also achieved.
However, even this start method uses reduced motor voltage
and the quadratic correlation between current and torque
described in the first section of this chapter is still valid. This
means, the lowest possible starting current is determined by
the combination of motor and load characteristics.

Fig. 10 Soft starting – torque control
For optimal starting performance, correct setting of the soft-
starter’s parameters such as initial torque and end torque at
start and start time is important. The choice of parameters is
explained in detail in section 8.7, page 55.
2.3 Other starting methods
In contrast to the preceding sections of this chapter, which
focused on squirrel-cage motors, slip-ring motors are dealt
with later on. A slip-ring motor is equipped with a wound
rotor; one end of each rotor winding is available for external
connection via slip-rings. These motors are often optimized
for rotor resistance starting, e.g. with short-circuited rotor
windings they develop a very low torque at an extremely
high current. For starting external resistances are connected
to the rotor windings. During the start, the resistance value
is decreased in several steps until the rotor windings are
short-circuited at nominal speed. The following figure
shows typical torque and current characteristics for a slip-
ring motor during the start with an external rotor-resistance
starter.
Fig. 11 Rotor-resistance starting
Because of the low starting torque it is often not possible to
short-circuit the rotor windings and replace the rotor-resist-
ance starter with a softstarter. However, it is always possible
to use a frequency inverter instead. The following illustra-
tion shows how the torque and current characteristics are
affected when the stator frequency is changed.

Fig. 12 Voltage/frequency regulation
Thus, such a motor can be started with a quite simple fre-
quency inverter with voltage-frequency regulation. This
solution is even valid for all other applications, which for
some reason (high load torque compared to motor torque
etc.) cannot be started by a softstarter.
2.4 Use of softstarters with
torque control
To determine if a specific application benefits from using a
softstarter at all, the correlation between the motor’s torque
characteristic during the start and the load’s requirements
has to be evaluated. As it can be seen from the examples
above, the application will only benefit from using a soft-
starter if the load torque during the start is clearly below the
motor’s starting capacity. However, even loads with a high
initial release torque may profit from a softstarter. In this
case an initial torque boost can be used, thereafter the start
ramp is continued reducing the starting current considera-
bly.
The profit can be maximized when using a softstarter with
torque control. To be able to configure the torque control
parameters for optimal performance, the load characteristics
(linear, square or constant load, need of initial release
torque) must be known. In this case a proper torque control
method (linear or square) can be chosen and torque boost
can be enabled if needed. A description of the load charac-
teristics of several common applications and guidelines for
proper settings are found in chapter 6. page 31, Applications
and Functions Selection. Optimization of the torque control
parameter is explained in detail in section 8.7, page 55.

3. Mounting
This chapter describes how to mount the MSF 2.0 soft-
starter. Before mounting it is recommended that the installa-
tion be planned out first:
• Be sure that the softstarter suits the mounting location.
• The mounting site must support the weight of the soft-
starter.
• Will the softstarter continuously withstand vibrations
and/or shocks?
• Consider using a vibration damper.
• Check ambient conditions, ratings, required cooling air
flow, compatibility of the motor, etc.
• Do you know how the softstarter will be lifted and trans-
ported?
Make sure that the installation is performed in accordance
with the local safety regulations of the electricity supply
company. And in accordance with DIN VDE 0100 for set-
ting up heavy current plants.
Care must be taken to ensure that personnel do not come
into contact with live circuit components.
3.1 Installation of the
softstarter in a cabinet
When installing the softstarter:
• Ensure that the cabinet will be sufficiently ventilated
after the installation.
• Keep the minimum free space, see the tables on page 15.
• Ensure that air can flow freely from the bottom to the
top.
MSF-017 to MSF-835 are all delivered as enclosed versions
with front opening. The units have bottom entry for cables
etc. see Fig. 20 on page 21 and Fig. 22 on page 23. MSF-
1000 and MSF-1400 are delivered as open chassis.
3.1.1 Cooling
MSF-017 to MSF-250
MSF-310 to MSF-1400
WARNING! Never operate the softstarter with
the front cover removed.
NOTE: When installing the softstarter, make sure it does
not come into contact with live components. The heat
generated must be dispersed via the cooling fins to
prevent damage to the thyristors (free circulation of air).
