(1) the current limiting soft starting:

When the motor starts, its output voltage value increases rapidly until the output current reaches the setting

limiting value Im as it is shown in fig. 1-1. The voltage increases gradually, which makes the motor accelerate

gradually. When the speed of the motor is close to the rated value, the output current reduces to the rated current

Ie rapidly and the starting is finished. The current limiting value can be set according to the load condition and the

setting range is 1 to 4 times of the rated current of the motor.

(2)the voltage slope starting

Please see fig.1-2 for the oscillogram of the voltage variation of the voltage slope starting. U1 is the initial

voltage value output by the soft starter. When the motor starts, the output voltage of the soft starter increases to U1

rapidly and increase gradually according to the setting time t, the motor speed increased by the increase of voltage,

when voltage reaches the rated value Ue, the motor reaches to the rated speed, the starting is finished. The starting

voltage U1 and the starting time t can be set according to the load. The setting range of U1 is 30%-80% UeV and

the setting range of t is 0-180 s.

(3)stop

Free stop and soft stop modes settable by the user according to the load and working conditions

Free stop: Upon receiving the stop command, solid soft starter will switch off the bypass contactor

immediately blocks the output of the thyristor of the main circuit to stop the motor along with

the inertia.

Soft stop: In this stop mode, the power supply of the motor load switches from bypass contactor to the

thrysitor of the main circuit and the output voltage of the softer reduces gradually until the

motor stops operating. The stop time can be set according to the load requirement and the

setting range is 0-30S.

3.The protection function

Missing phase protection: When missing phase, block the pulse to prevent the motor winding burn out caused

by power supply missing phase.

External protection: When the control panel is fault, cut off the power supply

Start overtime protection: If the start time of voltage slope start, constant current start, pulse kick start

exceeds the setting “start time”, block the pulse, shut down the soft starter, carry on overtime protection.

Then, re-set the initial voltage and start time.

Over-current protection: When starting, motor current exceeds the limit value, then cut off the power within 1

s

Running current overload protection: When running, motor current overload exceeds setting time, then cut

off motor power

Running current inverse time overload protection: I ² t overload protection

Phase sequence protection: When input phase sequence is not the same as output phase sequence, block the

start signal, send signal to protect

Start interval protection: start times is less than 6 per hour, and time interval between 2 times is more than 10

minutes, or block start signal to protect.

6.2、Method of setting password and parameters

In order to guarantee the parameter of the soft starter will not be illegally modified, it is necessary to set the

parameters only when the password is validated. The password input method is shown as follows (an example

with 0200 as the existing password):

After entering the password input state, press “STOP” for direct exit in case of not modifying the parameters.

Password modification method is shown as follows (an example of modifying the former password 0200

into 0205):

When the soft starter is firstly used to control the operation of a motor, it is necessary to set the parameters

according to the related parameters of the motor and the load of the motor, otherwise, the starter will control the

starting motor according to the present value, which may result in the failure of the starting or abnormal

operation.

The parameter setting steps are shown as follows: an example of setting soft starting mode (9P=1) and soft

stopping (AP=20) to 20 seconds:

- P A S S Set to “-PASS” state according to the above password input method.

It will display the initial password and the lowest position will flash. Press “SHIFT” within 2 second in the state of displaying “-PASS”. - 0 2 0 0

- 0 2 0 0 Press “SHIFT” to enter the position modifying status and

this position will stop flashing.

- 0 2 0 5 Press “▲” or “▼” to modify the lowest position to “5”.

- 0 2 0 5 Press “SHIFT” to allow “5” flashing, and press “▲”

or “▼” to the corresponding position to

modify other positions, as above.

- G o o d Press “PRG” to save the new password after modification, and display “Good”.

6.4、Description of function parameters:

1 CT variety scale (function code OP)

Choose the parameters basing on the real variety scale of the inner set current transformer. The parameters

have been set by us before ex-factory, so it is not necessary for you to adjust.

2 Starting mode (function code 1P)

According to the different operating conditions on site, three kinds of starting modes will be offered: set

1P as (0,1,2).

0 means constant current soft start, applicable to no-load starting, light-load starting of the motor, low

capacity of the electric network or the occasion that the starting current is strictly limited. The current will be

kept at the set point of 4P from starting to the end of starting if this mode selected; (the starting characteristic

curve is as Fig. 1)

1 means voltage ramp starting, applicable to the starting of the motor with short time start and without

strictly limitation of the starting current, supplying terminal voltage for motors in voltage ramp mode, initial

voltage of the ramp will be set by 2P and the slope of voltage ramp will be adjusted by 3P; (the starting

characteristic curve is as Fig. 2), normally adopt this method.

2 means impulse step starting, applicable to the operating condition of load machinery for motor with

E-mail- [email protected] , Phone No- +91-9535-122013, Website:http://eaglewanlida.com

relatively bigger static friction, it is also started in voltage ramp mode and the different point is that a high

voltage with ultra-short duration will be added to the motor at the beginning of starting. (The starting

characteristic curve is as Fig. 3)

3 Starting voltage (function code 2P)

Valid when 1P is selected as 1 or 2, indicating the initial voltage value of voltage ramp, setting according

to the voltage percentage within the range of 30-80%. As the higher the starting voltage the larger the value is;

the larger the initial torque of the motor, the larger starting current of the motor is, please set carefully, normally

set as 40% (add this value appropriately in case of heavy load to guarantee the starting torque is more than static

torque of the mechanism) and adjust with 3P and 6P to allow the motor to complete the starting smoothly while

the starting current not exceeding 6P set point and within the 3P setting time range.

4 Starting time (function code 3P)

Set as 0~180S according to the load status of the motor; if the time is set relatively longer, the starting

current change slowly and the actual starting time of the motor will be prolonged correspondingly, so the time is

normally set as 30s, which will be increased properly in present of overtime protecting.

5 Constant current (function code 4P)

This parameter shall be valid only when 1P is set as 0, and the set value is the percentage of the rated

current of the motor (100~400%) ; When the motor is started, the soft starter will control the starting current of

the motor and shall reach and keep this parameter setting value to the end of starting. If the parameter setting is

small, the starting torque of the motor will be smaller and the starting time will be longer.

6 Rated current (function code 5P)

The parameter refers to the rated current of the motor and input the parameter value according to

nameplate of the motor. (Unit: A)

The setting range is 0-1060. Take A to present 10 when the rated current of the motor reaches 1000A or

above. For example, “5PA60” presents that the rated current is set to 1060A. If the starter is triangle mode wiring,

it will transfer the current automatically to make the current value displayed corresponding to the wire current of

the power supply.

7 Starting amplitude limiting current (function code 6P)

Set the parameter according to the percentage of rated current of the motor within the range100~600%,

and normally set as 300~500% of the rated current of the motor on the basis of the load of the motor. Cut off the

power supply of the motor when the starting current of the motor exceeds the set value, and the relevant fault

code will be shown on the monitor.

8 Step voltage (function code 7P)

This parameter shall be valid only when 1P is set as 2. It means that add an unexpected high-voltage

amplitude of ultra-short duration to the motor at the time of starting, and it can be set to 50~80% of the supply

voltage.

9 Step duration (function code 8P)

When the motor is in the starting mode of impulse step, the duration of unexpected high-voltage added to

the motor at the beginning of starting shall be set as 200~800ms.

10 Stopping mode (function code 9P)

Two stopping modes are offered according to the operating conditions on site when the wiring mode of the

starter is ordinary wiring mode (that is, set HP to 1):

0 presents free stopping; upon receiving the stop command, solid soft starter will switch off the bypass

contactor immediately and cut off the power supply of the motor to stop the motor along with the inertia.

1 presents soft stopping; after receiving the stop command, solid soft starter will make the silicon control

on state firstly, secondly switch off the bypass contactor, and then reduce the terminal voltage of the motor

gradually by controlling the silicon control until the motor stops, cut off the power supply. Applicable for the

stopping of the load of water pump to overcome the water-hammer effect, and the stopping of the load of

transmission band to eliminate the inertia attack of the object.

【Note】When soft stop mode is selected, the starter will have the function of soft stop only after starting and

stopping is completed after bypass operation. It has no soft stop function if it is stopped during operation; the

starter has no soft stop function when the HP is set as 0.

11 Soft stopping time (function code AP)

When the motor is in soft stopping mode, this parameter can adjust the soft stopping time of the motor (if

the pump head is high and the inertia of the object on transmission band is large, a relatively large parameter

value should be set; or a small value should be set. The value is adjustable between 0 and 180s), and it is skipped

in mode of free stopping.

12 I2t overload protection curve (function code bP)

Inverse-time-lag overload protection function for running current of the motor provides 4 inverse-time-lag

overload protection curves for users to choose (1, 2, 3, and 4). The relationship between overload multiple and

protection time is shown in figure 1, and the larger the overload current the shorter the response time is. The

starting current value of inverse time lag protection takes the larger one between 1.14Ie and (1+EP parameter)*Ie.

For example, set EP parameter to 20, thus (1+EP parameter)*Ie =1.2Ie which is above 1.14Ie, and the starting

current value of inverse time lag protection will be 1.2Ie.

Relationship between overload multiple and time of protection operation:

0 represents keyboard control (only the keyboard is valid while others are invalid)

1 represents remote control (there are two-wire and three-wire control modes, see the secondary wiring

diagram for details. Other control modes are invalid)

2 represents PC computer control (Other control modes are invalid)

3 represents keyboard + remote control (Other control modes are invalid)

4 represents keyboard + PC computer (Other control modes are invalid)

5 represents remote control + PC computer (Other control modes are invalid)

14 Specified time overload protection time (function code dP)

If the current overload of the motor exceeds the setting time during the running process of the motor,

switch to the emergency protection state and cut off the power supply of the motor. When the running current

of the motor reaches (1+EP) ×Ie, begin timing, and the protection time is adjustable between 0 and 180s.

15 Specified time overload protects the overload quantity (function code EP)

Set the parameter according to the percentage of the rated current of the motor within the range of 0 to

400%, specific time overload protection current of the motor =(1+EP parameter)×Ie .

16 Local address (function code FP)

Used for serial-port communication, and is unique in the same network.

17 Test function of minitype motor (function code gP)

Test function of minitype motor is invalid when gP is set to be 0;

Test function of minitype motor is valid when gP is set to be 1. It can enable the motor whose power is far

smaller than the rated starting value of the motor to conduct the routine inspection of the starter in testing or

maintenance environment. In the main loop power transmission condition, the starter turns to bypass operation

when the starting process is finished or reaches the starting time set by 3P. It has no protection functions of

overtime starting or output open-phase. gP returns to 0 state when the control voltage is broken.

Start the device with no-load test in main loop with no power transmission condition, and the device output

bypass signal when the starting time reaches the starting time 3P set. It has no protection functions of overtime

starting or output open-phase. gP returns to 0 state when the control voltage is broken.

When the test function of minitype motor is valid, set to the rated current of the minitype motor for test, and

the range of the setting current is 1 to 100. The amplitude current, I2t overload protection, the rated current of the

motor in specific time lag over load protection at this time is hP.

5P can also be set according to the rated current of the actual large motor, and the modification is not necessary.

19 Connection mode of the starter (function code HP)

The motor has two connection modes. For the motor of triangle wiring mode, the starter can concatenate into

it, and HP shall be set as 0 at this time; for the motor of routine wiring mode, HP shall be set as 1.

the fault:

1 The noise is abnormal when starting and running the motor:

Check if the activating line of silicon control (or module) is of poor contact, whether the silicon control

(or module) is damaged;

Check if the bypass contactor is damaged or is of poor contact, the contactor shall be shut off when

starting in normal status and closed while running;

Check whether there is open phase at the power end or load end, and check the connecting line;

Check if the settings of parameters are correct and appropriate.

2 The motor can’t be started or the starting failed:

Whether the terminals 13 and 14 are powered on 220VAC;

Check whether the indicator lamp of switching power supply is on, if not, check whether the fuse in

switching power supply is blown;

Check if the starting signal is normal or not, and terminal 11 is connected to terminal 8 in remote control

(detect the voltage between the two terminals with the 200VDC step of the multimeter, 0V for

connected), terminal 11 is disconnected to terminal 9 (detect the voltage between the two terminals with

the 200VDC step of the multimeter, 24V for disconnected), in case of one in fault, the on-off state is

incorrect, and it is necessary to change the switch;

Check if the main power supply is connected to the terminals L1, L2 and L3 or not;

Whether the power frequency is normal or not (50Hz);

Check whether the setting of parameters is correct and proper;

Check whether all of the connections are disconnected or getting loose according to the secondary

wiring diagram;

Whether the soft starter is overheated, it is necessary to reduce the number of starts in this case, and

restart after cooling;

If the soft starter is not hot, check whether the fault input terminal 10 is disconnected to 11 (detect the

voltage between the two terminals with the 200VDC step of the multimeter, 24V for disconnected), it

indicates that the temperature switch (85℃, normally closed) is damaged if disconnected, and it is

necessary to replace it;

Check whether all of the connections inside the soft starter are disconnected or get loose.

3 Abnormal stopping while running:

Check whether the voltage of the main power is abnormal and open phase is available or not;

Check whether terminals 6 and 7 are closed (detect the voltage between the two terminals with the

1000VDC step of the multimeter, 0 for closed), and then check according to the following steps if the

terminals are switched off; check whether the voltage at both ends of the control coil of bypass

contactor is 220VAC in case of being closed, if the voltage is 220VAC and the contactor is switched off,

which indicates the contactor is faulty, it is necessary to replace it;

In remote control, check whether the terminals 11 and 9 are closed (the method is as above), it indicates

that the remote control switch is damaged if closed, and it is necessary to replace it;

Whether the soft starter is overheated, and whether the temperature switch is switched off (i.e. whether

the fault input terminal 10 is disconnected to 11); if it is not hot and the temperature switch is switched

off, it indicates that the temperature switch is damaged and needs to be replaced;

Check whether all of the connections are disconnected or get loose according to the secondary wiring

diagram;

Check whether all of the connections inside the soft starter are disconnected or get loose.
