Why Choose Us

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. 


Starting Mode 

Voltage and current limiting double closed-loop starting

a) The motor will be under double closed-loop starting mode when code F9 is set to S(double closed loop). The voltage and current limiting closed-loop starting mode which adopts the double closed-loop control of voltage ramp and current limiting is a comprehensive starting mode requires both smooth starting and strict current limiting. It employs the prediction algorithm which estimates the operation status of the motor 

b)Output voltage wave of this starting mode varies with the motors and loadings. 

Soft stop

There're two types of stop mode forWS1Rseries soft starter, namely, soft stop mode and free stop mode.

a) The soft starter will be under soft stop mode when code F2 is not set to 0. Figure 12-6-1 shows the output current wave of the soft stop mode.Tis the soft stop time set by the code F2. Under this stop mode, power supply of the motor will be switched to thyristor output of the soft starter through the bypass contactor, and the output voltage of the soft starter will gradually drop from the full voltage to enable the rotation speed of the motor reduce smoothly to avoid mechanical shock until the motor stops running. The output cut-off voltage during soft start shall be equal to the starting voltage during start.

b)The soft stop mode can reduce and even eliminate surge of load of pumps and reduce the large current shock during soft stop. The soft stop current limiting value is the percentage calculated from the starting current limiting. 


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.
