Lenze assumes no guarantee for the suitability of the listed procedures and circuit samples. These operating instructions describe the product features without guaranteeing them.
Safety instructions General safety and application instructions for Lenze motors Safety instructions General safety and application instructions for Lenze motors (according to Low-Voltage Directive 73/23/EEC) General Low-voltage machines have hazardous live and rotating parts and possibly also hot surfaces. Synchronous machines induce voltages at open terminals during operation.

Safety instructions General safety and application instructions for Lenze motors Installation Ensure an even surface, solid foot flange mounting and exact alignment if a direct clutch is connected. Avoid resonances with the rotational frequency and double mains frequency which may be caused by the assembly. Turn rotor by hand, listen for unusual slipping noises.
General safety and application notes for Lenze controllers (to: Low-Voltage Directive 73/23/EEC) General Lenze controllers (frequency inverters, servo inverters, DC speed controllers) and the accessory components can include live and rotating parts - depending on their type of protection - during operation. Surfaces can be hot.

Safety instructions General safety and application notes for Lenze controllers Application as directed Drive controllers are components which are designed for installation in electrical systems or machinery. They are not to be used as household appliances. They are intended exclusively for professional and commercial purposes according to EN 61000-3-2. The documentation includes information on compliance with the EN 61000-3-2.

Technical data Holding brake (option) Permanent magnet holding brakes 3.4.1 Permanent magnet holding brakes These brakes serve as a holding brake to hold the axles when the machine is at standstill or deenergised. When controlling the brake it must be ensured that the brake is activated (released, engaged) at a speed of 0 min to avoid unnecessary and rapid wear on the friction surfaces of the brake.
Emergency stops lead to wear on the friction surfaces and also lead to the creation of dust. The lenze BFK 458 spring-operated brake can be adjusted up to 5 times. The BFK 418, 457 and 460 cannot be adjusted (Details catalogue and operating instructions for spring-operated brakes).
