Lenze launches new range of frequency inverters

Lenze’s new 8400 inverter drives series offers impressive, consistent scaling. The clear functional grading of the BaseLine, StateLine and HighLine versions makes selecting the right inverter for the drive axis a very simple process – and the value for money is spot on too. Lenze will present
the 8400 Inverter Drives as the newest member of the L-force drive and automation platform at the Hanover Fair from 21 to 25 April in Hall 14, booth H36.

All versions share the same kind of handling, operation, programming, logistics and service options. This makes working with the inverters incredibly simple. The cost savings available in all life cycle phases of a machine increase the value-added in the long term. In conjunction with matching geared motors, Lenze also supplies complete drive axes from one source.

Lenze, the specialist in drive and automation technology, is initially launching the 8400 inverter drives as BaseLine, StateLine and HighLine. The BaseLine is available with power ratings of between 0.25 and 2.2 kW (230V single phase) and 0.37 to 3 kW (400/500V three phase). The StateLine and HighLine versions cover the single-phase power ratings of 0.25 to 2.2 kW, also five different power ratings are initially available for three phase between 0.37 and 11 kW.

The 8400 BaseLine can be used as a voltage-controlled variable speed drive or in sensorless vector operation where it is suitable for continuous applications such as simple conveyor systems, pumps and fans. In terms of functionality and drive behaviour, it is the entry-level model.

In addition to the scope of the 8400 BaseLine, the 8400 StateLine offers functions such as S-ramps for gentle, lowwear acceleration, a unique flying restart circuit to smoothly pick up freewheeling loads and integrated brake handling to control service brakes. In addition to this, an HTL encoder can be connected to the 8400 StateLine, thereby extending its potential range of use. Typical applications include extruders, line and travelling drives, high-speed roller doors and simple lift tables or dynamic variable speed drives. The 8400 StateLine and HighLine have a CANopen interface fitted as standard for communication or diagnostics purposes. It also features another plug-in interface for extending to common fieldbus systems such as PROFIBUS, POWERLINK, EtherCat or PROFINET.

At the third level of this series, in addition to the functional range of the StateLine, the HighLine 8400 inverter drives are equipped with full-value integrated positioning control. These inverters are therefore recommended as efficient drives for applications like rotary feeders, filling systems, rolling and sliding doors or for positioning tasks in warehouse systems.

The common features shared by all inverters include the integrated interface for connecting up to a PC, the same operating conditions at 45°C without derating, the high overload behaviour of up to 200 percent of the rated current and the ‘memory module’, an interchangeable module that greatly simplifies commissioning and service. The devices are either programmed using the keypad or ‘L-force Engineer’ project planning software,that is provided free of-charge in the ‘StateLevel’ version. All inverters comply with RoHS and satisfy CE and UL requirements.
