Lenze L-Force 8400 StateLine Drive Inverters for Controlled Motion Distributors

8400 StateLine

Operating Instructions

Reference Manual

The 8400 StateLine is ideally suited to drive control with or without speed feedback providing precisely tailored solutions. The StateLine is used when communication via bus systems is required. In addition to this, the integrated brake management ensures significant wear reduction on the service brakes.

Typical applications for the 8400 StateLine include: palletizers, extruders, filling systems or travelling/variable speed drives.

  • "VFC eco" energy saving function ensures energy-efficient handling of limited resources
  • Control of synchronous motors without feedback
  • 200% overload current

The 8400 StateLine is intended for drive control with or without speed feedback and is also usedwhen networking via bus systems is needed. The integrated brake management system also delivers greatly reduced wear on the service brakes. Mains switching at too high a rate is also no problem for the StateLine, as the input circuit is protected fromoverload.

The 8400 StateLine is a step up from the BaseLine models for applications that must satisfy more stringent requirements. The StateLine is also ideally suited to applications such as palletizers, extruders, filling systems or travelling/variable speed drives.

The energy-saving function "VFC eco" supported by the 8400 reduces the energy required by the motor in partial load operation. Combine this with an MF L-force three-phase AC motor (inverter-optimised, 120 Hz) and what you get is a highly efficient, compact and cost-effective drive with high dynamic performance and a wide setting range. "VFC eco" can reduce your energy costs by up to 30%.

Intorq Brakes

Since the Braking Force comes from pressure springs, the braking torque, which is generated by friction, is available when no current is applied even in the event of a mains failure. The brake is released electromagnetically. The BFK457 is ideal for these situations. The speed of fitting with integral fixing screws and fixed air gap make this spring-applied brake even more attractive.

AC Drives

Dust on an Electronic Device can cause malfunction or even failure. Dust absorbs moisture, which also contributes to failure. Periodically spraying air through the heat sink fan is a good PM measure. Discharging compressed air into a VFD is a viable option in some environments, but typical plant air contains oil and water. To use compressed air for cooling, you must use air that is oil-free and dry
