Show/Hide Bookmarks 2 Safety General safety and application notes for Lenze motors 2 Safety 2.1 General safety and application notes for Lenze motors (to: Low-Voltage Directive 73/23/EEC) General Low-voltage machines have dangerous, live and rotating parts as well as possibly hot surfaces. All operations serving transport, connection, commissioning and maintenance are to be carried out by qualified, skilled personnel (observe EN 50110-1 (VDE 0105-100); IEC 60364).
Show/Hide Bookmarks Safety General safety and application notes for Lenze motors 2 Installation Ensure an even surface, solid foot or 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 during assembly. Turn rotor by hand, listen for unusual slipping noises. Check the direction of rotation when the clutch is not active (observe section 5).
Show/Hide Bookmarks 2 Safety General safety and application notes for Lenze controllers Operation Vibration severities vrms ≤ 3.5 mm/s (Pr ≤ 15 kW) and 4.5 mm/s (Pr > 15 kW) are acceptable when the clutch is activated. If deviations from normal operation occur, e.g. increased temperatures, noises, vibrations, find the cause and, if necessary, contact the manufacturer. Switch off the machine in problematic situations. If the drive is exposed to dirt, clean it regularly.
Show/Hide Bookmarks Safety General safety and application notes for Lenze controllers 2 Application as directed Drive controllers are components which are designed for the installation into electrical systems or machinery. They are not to be used as domestic appliances, but only for industrial purposes according to EN 61000-3-2. The documentation contains information about the compliance with the limit values to EN 61000-3-2.
Show/Hide Bookmarks 2 Safety General safety and application notes for Lenze controllers Electrical connection When working on live drive controllers, the valid national regulations for the prevention of accidents (e.g. VBG 4) must be observed. Carry out the electrical installation in compliance with the corresponding regulations (e.g. cable cross-sections, fuses, PE connection). More detailed information is given in the corresponding documentation.

The listed values apply for operation with Lenze servo inverters 9300 or ECS: – Operation at 400-V mains – Switching frequency 4 kHz, 8 kHz or 16 kHz. ƒ For operation with other servo inverters: – Do not fall below 4-kHz switching frequency. – Depending on the modulation and control mode of the servo inverter, the temperature monitoring may respond.
Show/Hide Bookmarks Technical data Rated data Holding brake (option) 3.3 3 Holding brake (option) The MDXLS servo motors can optionally be fitted with a spring-operated brake. The brakes used are not fail-safe brakes in the sense that a torque reduction cannot occur through uncontrollable interference factors, such as through the entrance of oil. With long motor supply cables, the ohmic voltage drop along the cable must be observed and compensated for by a higher voltage at the cable entry.

If used as service brake, the permissible friction energy must not be exceeded; otherwise it would destroy the brake. Permissible operating speeds and ratings E Spring-operated brakes catalogue. Emergency stops from a higher speed are possible, but wear increases with high switching energy.
