Why Choose Us

WSTR 3000 series soft starter possesses complete protection functions to protect the operation security of the soft starter and the motor. Here is Motor thermal protection tripping time curve based on IEC60947-4-2 standard is shown as follows:

1


Connection Of The Main Circuit And The Grounding Terminal

(I) Main circuit power input terminal (R,S, T) 

a.Connect the main circuit input terminals R, S, T to the three-phase AC power through the circuit breaker for circuit protection or circuit breaker with leakage protection without considering the connection sequence

b.Do not use ON/OFF of the main circuit power to control running and stop of the soft starter, instead, such should be controlled by means of the control terminal or RUN and STOP buttons in the keyboard panel of the soft starter upon power on. 

c.Do not connect the soft starter to the single-phase power. 

(2) Output terminals of the soft starter (U ,V ,W ) 

a.Output terminals of the soft starter should be connected to the three-phase motor in correct phase sequence. If the rotation direction of the motor is incorrect, switch connection of any two phases among U, V and W.

b.The output end of the soft starter shall not be connected to capacitor or surge absorber. 

c.If the wire between the soft starter and the motor is very long, the distributed capacitance between the wires will generate high­frequency current which may cause over-current tripping, leakage current increasing and poor current display precision of the soft starter. Therefore, it is suggested that the motor connection wire should be no more than 50m.

(3) Grounding terminal of the soft starter (〨 G)

a.For safety and noise reducing, the grounding terminal G of the soft starter must be well-grounded. To prevent electric shock and fire accidents, the metal enclosure and frame of the electric equipment should comply with the requirements of the national electronic procedures. 

2


Kick Mode

a)The soft starter will be under kick starting mode when code F9 is set to 2(kick+ current limiting) or 3(kick + voltage). Figure 12-3-1 and 12-3-2 show the output change wave of the kick starting mode. In some occasions with heavy load, this starting mode can be used when the motor fails to be started due to effect of the mechanical static friction force. During start, apply a relatively high fixed voltage to the motor for a limited period to overcome the static friction force of the motor load to rotate the motor, then the motor will be started in the current limiting or fixed voltage ramp method.

b)Before using this mode, the motor shall be started through the non-kick mode, and this mode shall be only used when the motor fails to rotate due to high friction, otherwise, starting with this mode shall not be used to reduce the unnecessary shock caused by large current.

3


Current Ramp Starting Mode

a)The motor will be under current starting mode when code F9 is set to 4(current ramp). Figure 12-4-1 shows the output current wave of the current ramp starting mode, I 1 is the time value set by code F 1.

b)The current ramp starting mode possesses strong accelerating capacity, when used in bipolar motor, it can shorten the starting time to a certain extent.

4


Free Stop

a) The soft starter will be under free stop mode when code F2 is set to O(free stop). Under this type of stop mode, upon receiving the command, the soft starter will disconnect the bypass contactor immediately and prohibit the voltage output of the thyristor of the soft starter, and then the motor will gradually stop due to load inertia. The code can be set to this mode when the soft starter is under the one-to-N connection method to avoid the phase loss fault alarm during output switching. 

b)Generally, in order to prolong the service life of the soft starter, free stop mode should be selected if there' s no necessary for soft stop. The free stop mode fully inhibits instantaneous output and thus it can prevent the instantaneous large current shock in the special application occasions. 

There are six different starting modes with the WS1R 3000 series soft starters which apply to various complicated motors and loading situations, among which users can select according to different application ranges.
