Service

If you need our service, please indicate the following:

• complete nameplate information
• detailed description of problem
• if possible, add digital images to the description

The identification of spare parts requires the nameplate data of the product with the manufacturers serial number.

Disposal note

Dispose the products properly and in compliance with local regulations

• Gears, shafts, bearings as steel
• Gear housing as aluminum or iron
• Worm wheels as non-ferrous metal
• Lubricants must be collected and disposed properly
• Motors as motor scrap ingredients aluminum, iron, copper, plastics
• Electronic components as electronic scrap

Mechanical installation

• Before mounting,remove the corrosion protection of the output shaft and grease the shaft surface
• Motor installation free of shock and tension
• Pay attention to alignment when using a coupling
• Use the threaded bore on shaft end for fixing transmission elements, avoid shocks, cover coupling parts in operation
• Components fitted on motor shaft have to be ballanced dynamically.
  Rotors are ballanced with half key in factory.
• After installation check sufficient ventilation of motor
  Keep the ventilation channels free, attend the minimum space for ventilation
  Avoid intake of heated air.
• Prevent insertion of foreign objects in vertical motor position
• Choose place of installation according to the protection standard of the motor.
• Consider maximum length of screws when fixing the motor flange B14.

Electrical Connection

• Connect the motor to the main free of voltage, (disconnected and secured against start up), made by qualified personnel, with consideration of valid restrictions
• Consider informations on name plate
  Type of current, mains voltage and frequency have to be compliant to name plate data. Deviations in graph and symmetry increase the motor temperature and can affect the electromagnetic compatibility.
  Consider type of duty and type of protection of the motor
  If not otherwise stated:Duty cycle S1, permissible ambient temperature -20°C..+40°C, installation altitude up to 1000m above mean sea level
• Consider electrical connection and supplied date sheets
• Use motor protection switch or full motor protection
• Execute the electrical connection safely and permanent
  Execute the protective ground safely
• Tightening torque for terminal board connections: M4-1.2Nm, M5-2Nm, M6-3Nm, M8-6Nm
• Consider minimum clearances in terminal box: Un≤550V 8mm, Un≤725V 10mm
  Pollution, moisture and foreign substances are not permitted in terminal box
  Close terminal box and non-used cable entries dust and water proof
  Use terminals with insulated shaft only
  
• Direction of rotation: CW at connection L1-U1, L2-V1, L3-W1
  Change direction of rotation: exchange of 2 main cables (L1↔L2)
• Consider installation notes of inverter for motors with integrated frequency inverter

Electrical Connection - Encoder system

• EMV conform wiring is base of unfailing function
  Use shielded cable only!
  Make attention to cable quality (e.g. towing cable)
• Shield the cable on both ends, use whole cross section of wiring

Startup

• Check insulation resistance of winding before startup. The value should be ≤1.5 MΩ.
• Check the correct function of brakes for braked motors.
• Fix the key on motor shaft at start without coupling.
• Use drive temporary without load and check for irregularities
• Check current consumption with load, detect reason of variances (vibrations, noises) or abnormal increase of temperature. If necessary, contact manufacturer.
  Vibration severities between 3 and 4 mm/s with load are harmless

Inspection and maintenance

• Clean the air intakes periodically in case of heavy contamination
• Check motor bearings regulary, replace if abnormal noise or warming, recommended change after 3-4 years.
• Check installed seals, replace if damaged
• Pay attention to proper mechanical and electrical connections
