Fundamental safety instructions 2 2.1 General safety instructions

DANGER

Danger to life due to live parts and other energy sources

Death or serious injury can result when live parts are touched. • Only work on electrical devices when you are qualified for this job. • Always observe the country-specific safety rules.

Generally, six steps apply when establishing safety: 1. Prepare for shutdown and notify all those who will be affected by the procedure. 2. Disconnect the machine from the supply.

– Switch off the machine. – Wait until the discharge time specified on the warning labels has elapsed. – Check that it really is in a no-voltage condition, from phase conductor to phase

conductor and phase conductor to protective conductor. – Check whether the existing auxiliary supply circuits are de-energized. – Ensure that the motors cannot move.

3. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or water.

4. Isolate or neutralize all hazardous energy sources by closing switches, grounding or short-circuiting or closing valves, for example.

5. Secure the energy sources against switching on again. 6. Ensure that the correct machine is completely interlocked.

After you have completed the work, restore the operational readiness in the inverse sequence.

WARNING

Danger to life through a hazardous voltage when connecting an unsuitable power supply

Touching live components can result in death or severe injury. • Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-

(Protective Extra Low Voltage) output voltages for all connections and terminals of the electronics modules.

4.2.3 Storage The motors can be stored for up to two years in a dry, dust-free room that is not susceptible to vibration (veff < 0.2 mm/s) without the specified storage time being reduced.

NOTICE

Seizure damage to bearings

If the motors are stored incorrectly, bearing seizure damage can occur (e.g. brinelling) as a result of vibrations.

Storing indoors ● Apply a preservation agent (e.g. Tectyl) to bare, external components (e.g. shaft ends) if

this has not already been carried out in the factory.

● Store the motor in an area that fulfills the following requirements:

– Dry, dust-free, frost-free and vibration-free The relative air humidity should be less than 60 % and the temperature should not drop below -15 °C (to EN 60034-1).

– Well ventilated

– Offers protection against extreme weather conditions

– The air in the storage area must not contain any harmful gases.

● Protect the motor against shocks and humidity.

● Make sure that motor is covered properly.

● Avoid contact corrosion. You are advised to rotate the end of the shaft manually every three months.



Protection against humidity If a dry storage area is not available, the following measures must be taken:

● Wrap the motor in humidity-absorbent material and then wrap it in film so that it is air tight.

● Include several bags of desiccant in the seal-tight packaging. Check the desiccant and replace as required.

● Place a humidity meter in the seal-tight packaging to indicate the level of air humidity inside it.

● Inspect the motor on a regular basis.

7.2 Configuration

Note Assigning the parameters

Before you switch on the motor, ensure that the parameters of the frequency inverter have been assigned correctly. Use the appropriate commissioning tool. The "STARTER" commissioning tool is supported as of SINAMICS version 4.7.

Further details on the configuration can be found in the FAQs "Encoderless operation of 1FK7 on SINAMICS G120" - Chapter 4.

7.3 Switching on

NOTICE

Uneven running or abnormal noise

The motor can be damaged by improper handling during transport, storage or installation. If a damaged motor is operated, this can damage the winding or bearings and could even destroy the system. • If the motor is not running smoothly or is making abnormal noise, shut the motor down

and try to determine the cause of the fault as it runs down.

NOTICE

Observe the maximum speed

The maximum speed nmax inv and nmax mech are the highest permissible operating speeds. Exceeding these speeds can result in material damage or could even completely destroy the motor and the inverter. • Make sure that an appropriately configured controller or activated speed monitoring in

the drive does not permit a higher maximum speed. The maximum speeds for motor and inverter are specified in the data sheet.

Commissioning 7.4 Ramp-up behavior


7.4 Ramp-up behavior

Open-loop-controlled operation The motor starts up in controlled operation and switches to automatic operation at approx. 15 % of the rated speed. There are restrictions regarding the ramp-up time and overload capability in controlled operation. General statements regarding the ramp-up time and overload capability cannot be made as they are directly related. Start-up with a higher overload requires a correspondingly longer ramp-up time. Controlled operation in the lower speed range is shown by the dashed M-n characteristics. The characteristics are contained in the Product Information.

Additional Product Information is included in the Appendix under the SIOS notification "Product Information on SIMOTICS S-1FK7 G2 without encoder/resolver", entry ID 98799415. The most important factor for the ramp-up behavior is the inverter / Power Module (PM) that is deployed.

Automatic operation The motor is operated automatically between 15 % and 100 % of the rated speed. There are no restrictions to the overload capability in this range.

2. Disassemble the motor.

WARNING

Motor parts can fall

The motor is made up of heavy parts. When disassembling, these parts can fall and cause death, severe injury and material damage. • Secure the motor parts being disassembled to prevent them falling.

WARNING

Injury as a result of suspended loads

When disassembling, motor parts can cause injury as a result of unpredictable movement. • Only use perfectly functioning hoisting and load suspension equipment dimensioned to

carry the motor load. • Pay careful attention to possible movement when motor parts are released. • Do not stand under suspended loads or in their slewing range. • When placing down motor parts, ensure that they cannot roll.

3. Dispose of the motor parts or return the motor parts to the manufacturer.

● Dispose of the motor parts according to the information in Chapter "Disposal" (Page 55).

Disposing of permanent magnets Permanent magnets must be demagnetized prior to disposal. This helps avoid potential hazards caused by permanent magnets during and after disposal. Permanent magnets are heated to demagnetize them.

Permanent magnets can be demagnetized in one of the following ways:

● Have a specialist disposal company thermally treat the motor

● Hand over the motor to the manufacturer who can then remove and demagnetize the rotor and/or permanent magnets.

Note

Rotors that have been removed but are still magnetized cannot be transported.

Note Removing the rotor

A magnetized rotor may only be removed by the manufacturer. Contact the Siemens Service Center.
