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.

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 themotor will change corresponding. (See figure6-3). It is
convenient to judge the director of the motor.

When receiving thestop signal, the terminals K22,K24 isopen, the bypass
contactor is disconnect.The trigger signal of theSCR module is blocked
at the same time. Motor inertia stop according the load.

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 soft stop time factor.
To gain the smooth stopeffect, the oft top ime should be set
carefully.
