1.Function and Feature
SSXA/SSXB series LED AC motor soft starter is new type starting equipment with advanced
international level. This equipment designed and manufactured by the technique of power
electronics microprocessor and modern control theory. This equipment can limit the start current
efficiently when the asynchronous motor starts. It is widely applied in the field such as winding
machine, pump, transition and compressor etc. It is the ideal product to replace the traditional
voltage dropping start equipment such as star/triangle conversion, self-coupling voltage dropping,
magnetic control dropping voltage etc.
Function
◆ Reduce the starting current of motor; reduce capacity of power distribution; reduce the
investment cost；
◆ Reduce the start stress; prolong the operation lifetime of the motor and correspond equipment；
◆ Smooth and steady starting and soft stopping; The Water hammer and surge can be avoid；
◆ Several sorts of starting mode, wide range setting of the current and voltage. It can be used
in a lot of load conditions, so the technic can be improved；
◆ Perfect and reliable protection; The safeguard of the motor and relative equipment can be
achieved effectively；
◆ It can be used in the state in which motor should star and stop frequently。
Feature
◆ Starting Mode：Based on the load characteristics, different starting mode can the related
parameters can be selected. So the best starting effect can be gained；
◆ Technical Performance：The higher performance microprocessor and software are used, so the
control circuit is simplified. The best perform speed can gained without the adjustment of the
circuit parameters；

4. Operating principle
There are three pairs of anti-parallel thyristors connected to the stator of motor. Using
the electric switch feature of the thyristors, the voltage of the motor can be controlled by
changing the triggering angel of the thyristors. The triggering angel of the thyristors is
controlled by microprocessor. So the motor can be started softer and smooth. After the equipment
is up to full voltage, it outputs a bypass signal. User can use this signal to control the bypass
contactor to supply the motor. See figure4-1.

6. Control mode
This product has three start modes: Voltage Ramp and Current Limit and jogging. These start
modes is independent. Only one of them can be chosen. Text below introduce that the different
of them and which mode should be selected.
6.1 Voltage Ramp
The waveform of the voltage shows in Figure 6-1. U1 in figure is initial output voltage. When
starting, the output voltage is up to U1 immediately, and then ramps up gradually according to
the parameter Start Time t setting in advance. Then the motor accelerates continuously. When the
output voltage reaches the rate value Ue, the speed of motor reaches the rate speed. Starting
process is finished. The Initial Voltage U1 and the Start Time t can be set according to the load.
The range of U1 is 5~75% Ue, and the range of t is 1~200s.
This mode is used in the state with large inertia load, or in the state in which the current
is not the important parameter but the stability is important. Using the mode, the mechanical
stress and starting striking may decreased greatly. The bigger the initial voltage is, the more
the initial torque and starting striking is. The time of starting is related to the parameter
of Starting Time and load. It is unconcerned with current limited. For detail see chapter 8 and
chapter 9.
6.2 Current Limit
At the Current Limiting mode, the output voltage increases quickly until the output current
reaches the limited current value Im. See figure 6-2. And then the output current maintains below
this limited value. Then the output voltage is increased gradually, and the motor accelerate
gradually; when the motor's speed is close to the rated，the output current decreases quickly
to the rated value Ie, the starting is over. The limited current value can be set according to
the load instance. The range of this parameter is 0.2-4Ie.
This mode is used in the state in which the current is very important parameter. Special in the
state in which the grid capacity is small. The parameter of the current limit multiples should
be set 2.5-3Ie. If this value is small, the starting will be abnormal. At this mode, the time
of starting is concerned to the parameter of the Current Limit Multiples. The more this value

is, the shorter the time of starting is, Vice versa. For detail see chapter 8 and chapter 9.
6.3 Jogging
At this start mode, the output voltage reaches the initial voltage U1 quickly, and remains
unchanged. Changing the U1, the output voltage and torque of the motor will change corresponding.
(See figure 6-3). It is convenient to judge the director of the motor.
6.4 Heavy load
The waveform of the voltage shows in Figure 6-1. U1 in figure is initial output voltage. When
starting, the output voltage is up to U1 immediately, and then ramps up gradually according to
the parameter Start Time t setting in advance. Then the motor accelerates continuously. When the
output voltage reaches the rate value Ue, the speed of motor reaches the rate speed. Starting
process is finished. The Initial Voltage U1 and the Start Time t can be set according to the load.
The range of U1 is 5~75%Ue, and the range of t is 1~200s.
This mode is used in the state with large inertia load, or in the state in which the current
is not the important parameter but the stability is important. Using the mode, the mechanical
stress and starting striking may decreased greatly. The bigger the initial voltage is, the more

the initial torque and starting striking is. The time of starting is related to the parameter
of Starting Time and load. It is unconcerned with current limited. For detail see chapter 8 and
chapter 9.
6.5 Stop Mode
There are two stop modes. User can set this parameter according to load and working condition.
●Free stop
When receiving the stop signal, the terminals K22, K24 is open, the bypass contactor is disconnected.
The trigger signal of the SCR module is close at the same time. Motor inertia stops according the
load.
●soft stop
At this stop mode, when receiving the stop signal, the bypass contactor is disconnected. At
the same time, motor is controlled through SCR. The output voltage decreases gradually. At last
motor stop completely. The stop time is related to the parameter of load and factor of soft stop
time. To gain the smooth stop effect, the Soft Stop Time should be set carefully.

10. Displayed Current Calibration
The displayed current of each Soft starter is calibrated before leave factory. If user finds
the current value showing on the keyboard is not equal to the actual current value, this parameter
can be calibrated again.
WAY1:Set the starting mode to Jogging, and the motor must be connected to its load, the parameter
of Jogging Voltage is set below 40%, keep press RUN key (enter the Jogging state), press PRG
and up or down key at the same time to modify this value until it is equal to the actual current.
Then release the RUN key and PRG key, the modified parameter save automatic.
The other way can be adopted when circumstances permit.
WAY2: At the Bypass state, press RUN+▲ key or RUN+▼ key, this parameter can be modified to match
to the actual current.
