Product Family — AU6800 Soft Starters

Soft Starters for Controlled Motor Starting and Stopping

Not every motor needs continuous speed control — many need a controlled start, a controlled stop and protection in between. The Ausenist AU6800 series is an online soft starter and cabinet line, published for three-phase motors from 55 kW to 400 kW, built around adaptive control of the motor's acceleration and deceleration curves.

Adaptive start and stop control

The 6800 documentation describes a soft starter that reads the motor's data during starting and stopping and adjusts accordingly. Instead of applying a fixed voltage ramp, the starter controls the acceleration curve and the deceleration curve: the user selects the curve that suits the load type, and the starter works to accelerate the load in the most stable way that curve allows. The same adaptive approach applies on stopping. A series of starting methods is provided so the starting behaviour can be matched to different load conditions.

What the AU6800 documentation lists

Soft starter or VFD?

The AU6800 is an online-type starter for the 55–400 kW class, and its documentation covers the start and the stop. A variable frequency drive controls speed continuously across its published frequency range. Both product types are in this catalogue — see the VFD vs soft starter comparison.

Ordering notes

Soft starters are sized to the motor's rated current and starting duty, not only its kilowatts. With your enquiry, send the motor nameplate power and current, the load type (pump, fan, compressor, crusher, conveyor) and how many starts per hour the duty involves; ask for the starter or cabinet configuration for that motor to be stated in the quotation. Minimum order is 1 piece on the main catalogue lines, as published on the platform store.

Frequently asked questions

What motor sizes does the AU6800 cover?

The published online soft starter range is 55 kW to 400 kW for three-phase motors at 380 V class. For a smaller motor, state its rating in the enquiry and ask for the documented options to be stated in the quotation.

Can the display language be changed?

The documentation states the LCD shows feedback in Chinese and English, and that other languages can be customised. Confirm the language you need when you enquire.

Does a soft starter save energy like a VFD?

No energy-saving figure is published for the AU6800. Its documented benefits are controlled starting and stopping, reduced mechanical and electrical stress, and protection. See the comparison page.
