wrong
Please change the parameter correctly, or you can press the "YES" key to
power on the starter again to recovery the default setting.

the contactor is not closed, the motor will stop running, so you can check whether the wiring of the bypass
contactor is right.
7.2 The starting mode and application
The EM-GS series soft starter has six starting modes for the user to select according the motor and load equipments.
7.2.1 Current-limit to start
(The
F9
code is set as"0") Diagram 7.1 shows the waveform of motor current . I1 is the starting limit-current preset
value. When starting, the output voltage rises quickly till the motor current up to I1 value and not beyond this value.
The motor runs steadily in pace with the rising of output voltage, and when the motor runs to be the rated speed, the
output current will have a quick-drop and down to the motor rated current (Ie value),then the bypass contactor is
working, the stating process finished.
Note
:When motor load is too light or I1 preset value is too high, the max current of starting may can not reach I1
value. This starting mode fits for the conditions which requires strict current limit of starting.

F9
code is set as"1") Diagram 7.2 shows the output voltage waveform. In the diagram, the U1 is the initial
