Why Choose Us

Yueqing Winston Electric CO.,LTD has made further technical improvement in both the software and the structure of the soft starter according to the market demand. The soft starter provides complete motor protection functions including start control, running and overloading, phase failure, three-phase unbalance, over-voltage, under-voltage protection and so on. As another great achievement in the intelligentization of motor protection and networked technology application, it simplifies the circuit, reduces the volume, cuts the coat, makes installation and using more convenient.

Installation direction and space: to enable good ventilation and heat dissipating conditions during using of the soft star ter, the soft starter should be installed vertically with enough space for heat dissipating left around the equipment. The allowable minimum spaces are shown in figure 2.1 and figure2.2. 

In the event that the soft starter is installed inside the cabinet, besides the above requirements, the cabinet selected should be with good ventilation at the top and bottom, as shown in figure 2.3.

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.

2


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.

3


12-5 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. 

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.


WSTRD SERIES Motor soft starter have a wide range of applications.Including printing machinery, packaging machinery, winding machinery, film blowing machine, lathe, grinder, etc.Therefore, it is deeply loved by customers.
