Safety advices ¾ All operations on transport, assembly, setup and maintenance have to be done by skilled and qualified personnel. The qualified personnel must know and observe the following standards and guidelines: DIN VDE 0105, IEC 364, accident prevention regulations Inproper conduct may cause serious injury to persons and lead to damage. ¾ Before mounting and putting into operation read carefully the documents on hand. Follow the instructions for power supply (motor label and manual) and go by the rules of the technical data. ¾ Ensure a proper, low-impedance earth of the motor frame with...

> Synchronous servomotors within the LH055-LH142 range are precision motors. They are not foreseen to be connected directly to a three-phase power. They have to be operated only by a particular electronic power stage. A direct connection to main supply will lead to the destruction of the motor. > To wind up drive elements without backlash strictly use the foreseen thread within the motor shaft and if possible warm up the drive elements. Only use suitable aids to wind up the drive elements. > Avoid strong punches to the motor flange and the motor shaft. > Take care that the coupling is correctly...

4.1. About this manual This manual describes the synchronous servomotors of the LH055–LH142 range and it is directed towards specialist staff having knowledge of electrical and mechanical engineering. The servomotors are operated together with the corresponding servo drives. Therefore absolutely follow the documentation of the servo drive too. 4.2. Use in accordance with the requirements Synchronous-servomotors are specially designed to run machines with high requirements to dynamics. It is only allowed to operate the motors taking into consideration the environmental conditions described in...

The power transmission is effected by the cylindrical shaft-A end. Please take into consideration that high radial forces will occure when motors are driven via pinions or toothed belts. The values permitted at the shaft end depend on the number of rotations. The crest value at 3000 rpm is shown in the chart below. In case of acting force at the middle of the free shaft end, FR can be above 10%. Double conical gripping collets, probably combined with metal bellows couplings proved to be ideal coupling elements. Flange sizes according to IEC-standards, fit j6, accuracy as per DIN 42955 Tolerance...

The mating connectors are not included with the delivery. These, as well as completely assembled cables are available on request. The motors have the option of an installed brake. The permanent-magnet brake is operated by 24 VDC and blocks the rotor in voltageless state. The brake is to be understood as a standstill brake and it is not to be used for permanent slow downs during production. When brake is disengaged the rotor can operate without time lag, the operation is free from backlash. The brakes can be operated directly by the power stage (no personal safety !). In this case the erasing...

Installation / Setup 5.1. Important notes ¾ Check the relation between power stage and motor. Compare rated voltage and nominal power of the appliances. The wiring has to be carried out in accordance to the circuit diagram shown in the installation/operation manual of the power stage. ¾ Pay attention to strong earth connection of power stage and motor. ¾ Route the power and control cables separately from each other. When using motor power cables with integrated brake wires, the brake wires should be shielded. The shield weave has to be put on both sides. ¾ Lay all circuits with sufficient cross...

5.3. Environmental conditions With regard to the installation site of the motor please take into consideration the environmental conditions like ambient temperature: -20...+40°C, maximum mounting height: 1000m above sea level, relative humidity: 15...85%, noncondensing. A power reduction might possibly be necessary in case of tolerances to the a.m. environmental conditions. The motors are not suitable for outdoor installation or installation within aggressive or foreign substance afflicted atmosphere. 5.4. Drive elements The rotor of the motor has been electronically counterbalanced during production....
