Page 12: Product Selection
2. Product Selection 2.1 Product nameplate 2.2 Model and definition 2.3 Precautions for selection The soft starter must provide a force greater than the load resistance moment to complete the start-up. For ordinary loads such as water pumps, fans, etc., it is recommended to configure soft starters with the same or higher gear specifications, and for heavy loads such as ball mills, grade 6 fans and crushers, it is recommended to configure soft starters with high or second gear specifications. -

Page 22: Functions Selection And Description
5.4 Functions selection and description 5.4.1 Code FE (programming output) The programmable relay output function has two working modes: ①Programmable timing output mode and programmable state output mode ②When the setting item FE is 0~4 (10~14), the programmable output work is the timing output mode, and the starting time of the output is set as follows: FE setting value 0(10) - Page 23 Fig 5.4.2 5.4.3 Code F2 (soft stop time) When the stopping time is set to 0, it is a free stop. Too long stopping time will bring instability to the system. (Fig.5.4.3 ) Fig. 5.4.3 5.4.4 Code F5 (Starting limit current) When using this function, code F9 must be set to 0 or 2 or 4, and the starting current of the starter will run below the set value (50%- -500%).
- Page 24 the motor rated current|1 or below, and the starting process is completed. When the motor load is lighter or the set current limit value is large, it is normal that the maximum current at starting may not reach the set current limit value. Current limiting starting mode is generally used in occasions that have strict requirements on starting current.
- Page 25 When the setting item F9 is 4, set the starting mode to this mode. Fig. 5.4.6c is the output current waveform of the current ramp start mode, where 11 is the current limit value set by F5, and T1 is the time value set by F1. The current ramp starting mode has a strong acceleration capability, which is suitable for two-pole motors and can also shorten the starting time within a certain range.
