● When using 2-cable lifting equipment, ensure that the maximum angle of inclination is ≤45° according to ISO 3266 (DIN

580).

● Align the eyebolts so that the cables used for lifting are aligned with the planes of the eyebolts.

The motor can slide or topple over if it is not correctly lifted or transported. This can result in death, serious injury, or material damage.

● Use all the lifting eyes on the machine.

● When using the lifting eyes on the machine, do not attach any additional loads or weight. The lifting eyes are only

designed for the weight of the machine itself.

● Any eyes that are screwed in must be tightly fastened.

● Eyebolts must be screwed in right up to their supporting surface.

● Comply with the permissible eyebolt loads.

● When necessary, use suitably dimensioned lifting equipment, for example hoisting straps (EN1492-1) and load restraints

(EN12195-2).

The type of construction of the machine is stated on the rating plate.

If any transport locks are in place, remove them before commissioning. Store the transport locks or disable them. Use the transport locks when transporting the motors again or reactivate the transport locks.

The machines are packed in different ways depending on how they are transported and their size. If not otherwise contractually agreed, the packaging corresponds to the packing guidelines according to ISPM (International Standards for Phytosanitary Measures).

Comply with the images shown on the packaging. Their meaning is as follows:

Electromagnetic compatibility

Note If the torque levels are very unequal (e.g. when a reciprocating compressor is being driven), a non

current will be induced whose harmonics can have an impermissibl interference emissions as a result.

Note Converter

•

, disturbance voltages caused by the converter may occur on

the sensor cable.

The storage rooms must provide protection against extreme weather conditions. They must be dry, free from dust, frost and vibration and well ventilated.

For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be coated with an anti-corrosion agent which will last for a limited amount of time (<6 months). Apply suitable anti-corrosion measures for longer storage times.

Open any condensation drain holes to drain the condensation depending on the environmental conditions, every six months at the latest.

Permissible temperature range: -20 °C to +50 °C

Maximum permissible air humidity: 60%

For machines that have a special design regarding the ambient temperature in the operating state or the installation altitude, other conditions could apply regarding the storage temperature. In this case, refer to the machine rating plate for data on the ambient temperature and installation altitude.

Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce the useful life of the bearing grease (aging).

● For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12 months.

● Replace the grease if it is identified that the grease has lost its lubricating properties or is polluted. The consistency of the

grease will change if condensation is allowed to enter.

● For closed bearings, replace the DE and NDE bearings after a storage time of 48 months.

The motor can be damaged if you use it or store it unprotected outdoors.

• Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a superstructure or additional cover, for example.

If operated with a frequency converter, the emitted interference varies in strength, depending on the design of the

converter (type, interference suppression measures, manufacturer).

Avoid that the specified limit values stipulated for the drive system (consisting of the motor and converter) are exceeded. You must observe the EMC information from the manufacturer of the converter. The most effective method of shielding is to conductively connect a shielded machine supply cable to the metal terminal

box of the machine (with a metal screw connection) over a large surface area.

4.6.3

Reducing bearing currents during operation with converter (low voltage)

● If the design of the motor requires connection to a particular converter type, the rating plate will contain corresponding additional information.

● Correctly parameterize the converter. Parameterizing data can be taken from the machine rating plates. You can find parameter data here:

– In the operating instructions for the converter.

– In the SIZER engineering tool

– In the SINAMICS Configuration Manuals.

● Do not exceed the specified maximum speed limit n supplementary plate for converter operation as the highest speed.

● Check that the machine is cooled sufficiently for commissioning purposes.

The insulation system of SIMOTICS machines significantly exceeds the requirements of stress category B (IVIC B = medium stress). If voltage peaks higher than those specified according to IVIC B can occur, then observe the data in the respective Catalog:

● For a line voltage (converter input voltage) up to max. 480 V and operation connected to a SINAMICS G / SINAMICS S converter with uncontrolled/controlled infeed: Comply with the guidelines for configuring motor and converter.

● For line voltages (converter input voltages) higher than 480 V, motors, which are ordered for converter operation, have an appropriate insulation system.

● Operation with a converter from another manufacturer: Comply with the permissible voltage peaks according to IEC 60034-18-41 in accordance with stress category C, dependent on the particular line voltage (converter input voltage) and the motor insulation system.

. You can either find this on the rating plate n

max

or on the

max

The insulation system will be damaged if the supply voltage is too high for the insulation system. This can completely destroy the machine.

Taking the following actions will reduce the bearing currents:

● Ensure that the contacts are made over a large area. Solid copper cables are not suitable for high-frequency grounding because of the skin effect.

Equipotential bonding conductors:

Use equipotential bonding conductors:

● between motor and driven machine

● between motor and converter

● between the terminal box and the RF grounding point at the motor enclosure.

Selecting and connecting the cable

As far as possible, use symmetrically arranged, shielded connection cables. The cable shielding, made up of as many strands as possible, must have good electrical conductivity. Braided shields made of copper or aluminum are very suitable.

● The shield is connected at both ends, at the motor and converter.

● To ensure good discharging of high-frequency currents, provide contacting over a large surface area:

– as contact established through 360° at the converter

– at the motor, for instance with EMC glands at the cable entries.

Please contact the service center if necessary.

● If the cable shield is connected as described, then it ensures the specified equipotential bonding between the motor

enclosure and converter. A separate RF equipotential bonding conductor is then not necessary.

● If the cable shield is not connected due to special secondary conditions, or not adequately connected, then the specified

equipotential bonding is not provided. In this particular case, use a separate RF equipotential bonding conductor:

– Between the motor enclosure and protective ground rail of the converter.

– Between motor enclosure and driven machine

– Use braided flat copper straps or high-frequency cables with finely-stranded conductors for the separate RF

equipotential bonding cable.

– Ensure that the contacts are made over a large area.

To specifically reduce bearing currents, you must consider the system as a whole, which comprises the motor, converter, and driven machine. The following measures support you when reducing bearing currents and help to avoid damage:

● In the overall system, set up a properly meshed grounding system with low impedance.

● Use the common-mode filter (damping cores) at the converter output.

● Limit the rise in voltage by using output filters. Output filters dampen the harmonic content in the output voltage.

● The operating instructions for the converter are not part of this documentation. Refer to the configuration information for

the converter.

If the machine is operated from a low-voltage converter, insulated bearings are fitted at the NDE and an insulated encoder with insulated bearings (option).

Comply with the plates on the machine relating to bearing insulation and possible bridges.

Figure 4-1 Schematic representation of a single drive

The bearing insulation must not be bridged. Bearing currents can damage bearings.

• Also for subsequent installation work, such as the installation of an automatic lubrication system or a non-insulated vibration sensor, make sure that the bearing insulation cannot be bridged.
