Keypad Operation

The soft starter features a large-screen LCD display module and six micro keys for operating the display keyboard. These allow the user to perform soft starter start and stop operations, modify parameters, query faults and reset them.

1. Press the “PRG” key; use the up and down keys to select the parameter group

2. Press the “PRG” key again; use the up and down keys to select the parameter to be modified

3. Press the “PRG” key again; use the up and down keys to set the value of the parameter

4. Press the “PRG” key again to save the parameter value

5. Press the “EXIT” key to return to the main screen

6. Press “RUN” to soft-start the motor

7. Press “STOP” to stop the motor

8. Press and hold the up arrow key to clear the error record

9. Press and hold the down arrow key to reset to factory settings

Terminal Functions

1. Start: closed with terminals (5, 6) to start the motor

2. Stop: opened with terminal (5, 6) to stop the motor

3. Emergency stop: opened with terminal (5, 6) to stop the motor

4. Fault reset: closed with terminals (5, 6) to clear the fault state

5-6. Common digital input terminals

7-8. Output terminals: 4-20mA output; adjusted by parameter C26, C27, C28

15-17. Output relay B: 15 is normally open, 17 is normally closed

18-20. No function and reserved for ASF6K Series

Selection Guide

We have divided the motors into four categories according to starting characteristics, power factor and efficiency values. The correct soft start can then be quickly found according to the power of the motor. The first column shows the power of the ASF6K series 220V type, with a link to the variant. The second to fifth columns show the maximum motor power that can be handled.

ASF6K 220V Power (kW) Class 10 Motor (kW) Class 10B Motor (kW) Class 20 Motor (kW) Class 30 Motor (kW)
5.5 4.3 4.2 3.7 3
7.5 5.9 5.7 5.1 4.1

Class 10 – Light Loads

• Default

• Agitators

• Tumblers

• Band Saws

• Low Inertia Fans

• Unloaded Positive Displacement Pumps

(High current utilization; Smooth start-up; Soft starter selection is straightforward)

Class 10B – Standard Industrial Loads

• Chillers

• Lathes

• Escalators

• Transformers

• Unloaded Mixers

• Centrifugal Pumps

• Unloaded Conveyors

• Plastic & Textile Machines

• Equalized Air Compressors

(Common industrial applications)

Class 20 – Heavy or High Inertia Loads

• Ball Mills

• Rolling Mills

• Pelletisers

• Grinders

• Flour Mills

• Hammer Mills

• Circular Saws

• Loaded Mixers

• Loaded Conveyors

• Vibrating Screens

• Flywheel Presses

• Fully Loaded Air Compressors

(High inertia or load demand; Expect higher starting currents; Allow extra margin when selecting a soft starter)

Class 30 – Severe Duty Loads

• Crushers

• High Inertia Fans

• Wood Chippers

(Very high inertia or impact loads; Recommend selecting a soft starter with a higher current rating or considering a variable frequency drive)

Notice: In most three-phase systems, the default wiring is for the soft starter to be wired in series with the motor connected in delta. This is also the basis of our selection table. Click here for more details about motor soft starter selection.
