C, the starter should be power on to preheat for 30 minutes, and then to start. 5.2 Starting Mode and Application The EM-GW series soft starter has six starting modes for the user to select according the motor and load equipment. 5.2.1 Current limit (F9=0) Diagram 5.1 shows the waveform of motor current. - Page 19 5. Test Run and Application GW/GS32 Series User Manual Diagram 5.1 5.2.2 Voltage Ramp (F9=1) Diagram 5.2 shows the output voltage waveform. In the diagram, the U1 is the initial 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.

Page 20: Stopping Mode And Application
GW/GS32 Series User Manual 5. Test Run and Application 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. -
Page 21: Special Application
5. Test Run and Application GW/GS32 Series User Manual output ending voltage is the same as the starting initial voltage. Soft-stopping mode can reduce or remove the surge of the loading equipment such as the water pump. You can set the soft-stopping current limit value through the FF code to reduce the high current shock to the motor when stopping. -
