Curves indicating changes in the torque depending on the starting current of a threephase asynchronous motor.
Curves 1: direct line starting
Curves 2: starting in current limiting mode
Torque curve Ts1 indicates the total torque range available depending on the limiting
current Is1.
Limiting the starting current Is to a preset value Is1 will reduce the starting torque Ts1
to a value which is almost equal to the square of currents Is1/Is.
Example:
For motor characteristics: Ts = 3 Tn for Is = 6 In,
limit the current to Is1 = 3 In (0.5 Is)
resulting in a starting torque Ts1 = Ts x (0.5)² = 3 Tn x 0.25 = 0.75 Tn

With current limitation Is1, the accelerating torque applied to the motor is equal to the
motor torque Ts1 minus the resistive torque Tr.
The accelerating torque increases in the starting range as the speed changes and is
at its highest at the end of acceleration (curve 2).
This characteristic means that the load is taken up very abruptly, which is not
recommended for pump type applications.

Torque control on the Altistart 48 applies the torque to the motor during the entire
starting phase if the current required (curve 1) does not exceed the limiting current.
The accelerating torque can be virtually constant over the entire speed range
(curve 2).
It is possible to set the Altistart in order to obtain a high torque on starting for a rapid
motor speed rise whilst limiting its temperature rise, and a lower accelerating torque
at the end of starting for gradual loading.
This control function is ideal for centrifugal pumps or for machines with high resistive
torque on starting.

# Freewheel stop: the motor comes to a freewheel stop.
# Decelerated stop: this type of stop is ideal for pumps and can be used to effectively
reduce pressure surges. Torque control on the Altistart 48 reduces the effect of
hydraulic transients even if the load increases. This type of control makes adjustment
easy.
# Braked stop: this type of stop is suitable for high inertia applications as it reduces
the stopping time of the machine.

Other criteria can influence the selection of the Altistart 48:

(see the recommended application diagram on page 26)
In addition to the most frequently encountered wiring layouts, where the starter is
installed in the line supply of the motor and the motor is connected in star or delta
configuration, the Altistart 48 ATS48•••Q can be wired to the motor delta terminal in
series with each winding (see the application diagram below). The starter current is
lower than the line current absorbed by the motor by a ratio of
. This type of
installation enables a starter with a lower rating to be used.
Example: For a 400 V/110 kW motor with a line current of 195 A (nominal current for
the delta connection), the current in each winding is equal to 195/ , i.e. 114 A.
Select the starter rating with a maximum permanent nominal current just above this
current, i.e. 140A (ATS48C14Q for a standard application).
To avoid making this calculation, simply use the table on page 13.
This type of installation only permits freewheel stopping and is not compatible with
the cascade and preheating functions.

Starter wired in series with the motor
windings
: The nominal current and limiting current settings as well as the current
displayed during operation are on-line values (so do not have to be calculated by the
user).

&DXWLRQ: For this type of installation, observe the wiring scheme and the associated
recommendations on page 26.

(see the recommended application diagram on page 25)
The starter can be bypassed by a contactor at the end of starting (to limit the heat
dissipated by the starter). The bypass contactor is controlled by the starter and the
current measurements and protective mechanisms remain active when the starter is
bypassed.
The starter is selected on the basis of the 3 main criteria and one of the following
criteria:
If the starter is bypassed at the end of starting, the motor is always started from
cold state and the starter can be oversized by one rating.
Example: Select an ATS 48D17Q for an 11 kW motor in a standard 400 V application.
#
#
If the starter must be able to operate without the bypass contactor at the end of
starting, it does not have to be derated.
Example: Select an ATS 48D17Q for a 7.5 kW motor in a standard 400 V application.

θ – θe
Rth = ---------------P
θ = maximum temperature inside enclosure in °C
θe = maximum external temperature in °C
P = total power dissipated in the enclosure in W
The starter/motor combinations on pages 12 and 13 can only be used in ambient
temperatures 640°C.
For temperatures between 40°C and 60°C, derate the maximum permanent current
of the starter by 2% for every degree above 40°C.
Power dissipated by the starter: see pages 12 and 13.
If the starts are infrequent, it is advisable to bypass the Altistart at the end of starting
in order to reduce heat dissipation.
The power dissipated will then be between 15 and 30 W.
Add the power dissipated by the other equipment components.

The standard defines tests for different current levels which are designed to expose the device to extreme conditions.
Based on the state of the components after a short-circuit test, the standard defines 2 types of coordination.
# Type 1 coordination: Damage to the contactor and the starter is acceptable under 2 conditions:
5 No risk is posed to the operator
5 Elements other than the contactor and the starter are not damaged
Maintenance must be carried out after a short-circuit.
# Type 2 coordination: Minor soldering of the contactor contacts is permissible if they can be separated easily. The starter must not be damaged beyond repair.
The protection and control devices remain operational after type 2 coordination tests.
Once the fuses have been replaced, check the contactor.

The standard defines tests for different current levels which are designed to expose the device to extreme conditions.
Based on the state of the components after a short-circuit test, the standard defines 2 types of coordination.
# Type 1 coordination: damage to the contactor and the starter is acceptable under 2 conditions:
5 No risk is posed to the operator
5 Elements other than the contactor and the starter are not damaged
Maintenance must be carried out after a short-circuit.
# Type 2 coordination: Minor soldering of the contactor contacts is permissible if they can be separated easily. The starter must not be damaged beyond repair.
The protection and control devices remain operational after type 2 coordination tests.
Once the fuses have been replaced, check the contactor.

0RWRUVWRSE\GHFHOHUDWLRQYLDWRUTXHFRQWUROSXPSDSSOLFDWLRQThis type of
stop enables a centrifugal pump to be decelerated gradually on a ramp in order to
avoid a sudden stop. It can be used to dampen the hydraulic transient in order to
significantly reduce pressure surges.
The deceleration ramp time (dEC) can be adjusted.
During deceleration, the pump flow rate decreases and becomes negligible at a
certain speed. To continue to decelerate would serve no purpose. A torque threshold
(EdC) can be set at which the motor will change to freewheel stop mode, avoiding
the unnecessary heating of the motor and the pump.

The starter continuously calculates the temperature rise of the motor based on the
nominal current which has been set and the actual current absorbed. In order to
adapt the Altistart to individual motors and applications, several protection classes
are offered in accordance with standard IEC 60947-4-2:
class 30, class 25, class 20 (severe application), class 15, class 10 (standard
application), class 10 A, sub-class 2.
Different protection classes are defined for the starting capacities of the motor:
- cold start without thermal fault (corresponding to a stabilised motor thermal state,
motor switched off)
- warm start without thermal fault (corresponding to a stabilised motor thermal
state, at nominal power)
The motor thermal protection function can be disabled.
After the motor has stopped or the starter has been switched off, the thermal state is
calculated even if the control circuit is not energised. The Altistart thermal control
prevents the motor from restarting if the temperature rise is too high. If special motors
are used which do not have thermal protection via curves, provide external thermal
protection via probes or thermal overload relays.
The starter is factory-set to protection class 10.
The tripping curves are based on the relationship between the starting current Is and
the (adjustable) nominal motor current In.

ATS48///Q starters connected to motors with delta terminals can be wired in series
in the motor windings. This type of connection reduces the current in the starter by a
ratio of , which enables a lower rating starter to be used. The nominal current and
limiting current settings as well as the current displayed during operation are on-line
values and are indicated on the motor. For this application, the braking or
decelerating stop functions are inactive. Only freewheel stopping is possible.
The adjustment range of the nominal motor current and the limiting current are
multiplied by if the function is selected.
This function is not compatible with the following functions: motor phase loss
detection, motor preheating, cascade, decelerated stop and dynamic braking.
Use the scheme recommended on page 26 for this type of configuration.
This function can be used to test a starter on a motor whose power is very much
lower that of the starter. It can be used for example to check the electrical wiring of
a device.
The function is automatically cancelled when the starter is switched off.
The next time the starter is switched on, the starter returns to its initial configuration.

: When combined with a braked stop or decelerated stop
command, activating the logic input will stop the motor in freewheel mode.
5 ([WHUQDOIDXOW: Enables the starter to detect an external user fault (level, pressure,
etc.). When the contact is open, the starter changes to fault mode.
5 0RWRUSUHKHDWLQJ: Used to prevent the motor from freezing or to prevent
temperature variations which may cause condensation. When the logic input is
activated, an adjustable current flows through the motor after a time delay which can
be set between 0 and 999 s. This current heats the motor without causing it to rotate.
This function is not compatible with the following functions: connection to the motor
delta terminal and cascading.
5 )RUFHWRORFDOFRQWUROPRGH: If a serial link is used, this function can be used to
change from line mode (control via serial link) to local mode (control via the terminal).
5 ,QKLELWDOOSURWHFWLRQ: Enables the forced operation of the starter in an emergency
by overriding the main faults (smoke extraction system for example).
Warning: This type of use invalidates the starter warranty.
5 5HVHWPRWRUWKHUPDOIDXOW: Enables the fault to be reset remotely.
5 $FWLYDWLRQRIWKHFDVFDGHIXQFWLRQ: In this case, the motor thermal protection is
disabled and relay R1 is configured as the fault isolation relay. Can be used to start
and decelerate several motors one after the other with a single starter (see
application diagram on pages 28 and 29).

The starter has 2 logic outputs (LO1 and LO2) which, depending on their
configuration, can be used for remote indication of the following states or events:
# Motor thermal alarm: Indicates that the motor thermal state has exceeded the
alarm threshold and can be used for example to avoid starting a motor if the thermal
reserve is insufficient.
# Motor powered: Indicates that there may be current in the motor.
# Motor overcurrent alarm: The motor current is higher than the threshold set.
# Motor underload alarm: The motor torque is lower than the threshold set.
# Motor PTC probe alarm: Indicates that the thermal state monitored by the PTC
motor probe has been exceeded.
# Second set of motor parameters activated

The starter has 3 relays, 2 of which are configurable.
# (QGRIVWDUWLQJUHOD\5: Cannot be configured.
The end of starting relay controls the bypass contactor on the starter. It is activated
when the motor has completed the starting phase. It is deactivated when a stop
command is sent and in the event of a fault. The starter regains control when a
braking or deceleration command is sent.
#
5HOD\5DSSOLFDWLRQIXQFWLRQV
Relay R1 can be configured as follows:
5 Fault relay: Relay R1 is activated when the starter is powered and there are no
faults. It is deactivated when a fault occurs and the motor switches to freewheel
mode.
5 Isolating relay: The contact of relay R1 closes when a run command is sent and
re-opens when a stop command is sent, at the end of deceleration on a decelerated
stop or in the event of a fault. The line contactor is deactivated and the motor is
isolated from the line supply
(see application diagram page 25).

5 The analogue output AO provides an image of the following values:
motor current, motor torque, motor thermal state, cosine ϕ, active power.
5 The following settings are associated with the analogue output:
- the type of signal supplied: 0-20 mA or 4-20 mA
- the scale setting of the signal. The function associates the maximum amplitude
of the analogue output (20 mA) with a percentage of the nominal value of the
parameter, which can be set between 50% and 500%.

# A controller with 6 thyristors connected head to tail in each line phase is used to power the

5 Depending on the firing time and angle of the thyristors, it can be used to supply a voltage
M
which will gradually increase at a fixed frequency.

Limiting the starting current Is to a preset value Is1 will reduce the starting torque Ts1 to a value
which is almost equal to the ratio of the square of currents Is and Is1.
([DPSOH
On a motor with the following characteristics: Ts = 2 Tn for Is = 6In, current limiting at Is1= 3 In
or 0.5 Is results in a starting torque: Ts1 = Ts x (0.5)2 = 2 Tn x 0.25 = 0.5 Tn.

# Conventional electronic starting
To rectify problems caused by:
- mechanical stress when starting
- hydraulic transients during acceleration and deceleration in pump applications
Conventional electronic starting requires the use of several current limits or the switching of
several voltage ramps.
The settings become complicated and must be modified every time the load changes.
# Starting with the Altistart 48
The Altistart 48 torque control enables starting without mechanical stress and the smooth control
of hydraulic transients with a single acceleration ramp.
The settings are simple and effective, whatever the load.
