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 canbe started softer and smooth.After the equipmentis 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.

This product has three start modes: Current Limit and Voltage Ramp 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 Ramp6.1 Voltage Ramp
The waveform ofthe voltage shows in Figure 6-1. U1 in figureis initial
output voltage. When starting, theoutput voltage isup to U1immediately,
and then rampsup 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 motor reaches the rate speed.
Starting process finish. The Initial Voltage U1 and the Start Time t can be
set according tothe load. The range ofU1 is 5~75%Ue,and the rangeof it
is 1~200s.
This mode isused in the state with large inertia load,or in the state in
which the current is not the important but the stability is important. Using
th mode, the mechanicalstress 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
tarting ime and load. It is unconcerned with current limited. For
detail see chapter 8 and chapter 9.

6.2 Current Limit6.2 Current Limit
At the CurrentLimiting 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 rate speed the output current
decreases quickly to the rate value Ie, the starting process finish . The
limited value canbe set according to the load instance. The range of this
parameter is 0.2-4Ie.
This mode isused in the state in which the current isvery important.
Special in the state in which the grid capacity is small. The parameter of
the Current Limit Multiples should be set 2.5-3. If this value is small, the
starting will beabnormal. 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.
At the CurrentLimiting 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 rate speed the output current
decreases quickly to the rate value Ie, the starting process finish . The
limited value canbe set according to the load instance. The range of this
parameter is 0.2-4Ie.
This mode isused in the state in which the current isvery important.
Special in the state in which the grid capacity is small. The parameter of
the Current Limit Multiples should be set 2.5-3. If this value is small, the
starting will beabnormal. 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.

( phase lack protection ) and check if the system temperature is too
high ( overheatingprotection ) etc. Any fault is detected,the system
immediately enter Fault mode. If nofault is detected, the system
enter the Ready state, and shows on the keyboard panel. At the

When the soft Starter is power on, self-inspection is performed. The
self-inspection includes: testthe parameters that the user changed (
parameters wrong protection), check if the phase of voltage is not right
( phase lack protection ) and check if the system temperature is too
high ( overheatingprotection ) etc. Any fault is detected,the system
immediately enter Fault mode. If nofault is detected, the system
enter the Ready state, and shows on the keyboard panel. At the

the keyboard to indicate the starting mode ( Voltage Ramp or Current
Limit )
If the keyboard display correctly, press key to start the motor,
then the actual current displays on the keyboard.
At running state,press key to stop the motor, return toReady state.
During trial running, if the terminal mode is selected, setting
parameter according to item in chapter 8, table 8-1.
If the motor is not connected to the output load terminal U V W of
the soft starter, step above can also be executed. It is useful to check
wiring of operatesystem, bypass contactor, all the lamp etc.

Warning: At the course of trial running, anyabnormal phenomenon is
fond, such as:Abnormal sound, Smoking orabnormal smell,user should
cut off the power immediately.
If the motor is not connected to the output load terminal, power on,
voltage can bemeasured at the output power connections. This is
inductive voltage. This is normal phenomenon. This inductive voltage
disappears immediately after the motor is connected.
During trial running, if the starting effect is not ideal, user can modify
the parameter suchas starting mode, current, voltage and time etc.
