7. Test Run and Application

voltage value of starting. When starting, if the motor current is not more 400% than the rated current, the output

voltage of soft starter will rapidly rise to U1, and the output voltage rises gradually to the rated voltage (Ue), and the

motor gradually increase and until running at rated voltage and speed, and then the bypass contactor closed, the

starting process finished.

Starting time “t” is obtained in the standard experiment under the condition of soft starter with standard load. And

soft starter takes this control parameters as a benchmark, smooth acceleration by controlling the output voltage to

motor starting process to complete, not mechanically controlled time “t” and regardless smooth of whether the

motor speed. In view of this, when the load is lighter, starting time are often less than the set starting time, as long as

can smooth starter is normal

In general, the voltage ramp is generally used mode; it is suitable for requiring higher starting stability without strictly

current limitation case.

Note

:"T" is the automatic detecting starting time according to load. It will be less than set time when the load

equipments are light; this starting mode fits for the common occasions where the motor need to be started smoothly.

Diagram 7.2

7.2.3 Torque c current limit or + voltage ramp to start

(The

code is set as "2" or "3") Diagram 7.3 and 7.4 shows the output changing waveform of torque control

starting mode. When the static friction force of heavy load is too stronger to start the motor, user can use this starting

mode. At first state of starting, the motor needs a higher voltage to conquer the static friction force of heavy load,

and then starts with current-limit or voltage ramp mode to start the heavy motor.

Note

：

This mode will cause big-current shock to the motor, so if the voltage ramp or current limit starting mode can

startup the motor, it is better not to use this torque control mode to start.

Diagram 7.3 Diagram 7.4

7.2.4 Current ramp to start

(The

code is set as"4") Diagram 7.5 shows the output current waveform. The I1 in the diagram is current value

preset by

code, and T1 is time value present by

code. This starting mode has very stronger speed-up ability
