Full process operation specifications (detailed explanation of core chapters)

1. Transportation and Storage (Chapter 4)

Transportation requirements:

Weight limit: The weight of a single motor can reach 50kg, and lifting equipment that complies with the 98/37/EU Machinery Directive must be used

Operation taboos: Do not collide with the shaft end and bearing to avoid permanent magnet rotor adsorbing ferromagnetic objects

Transportation protection: Use suspension straps or lifting rings provided by the manufacturer, following the transportation regulations of the destination country

Storage conditions:

Environmental requirements: Dry, low dust, low vibration (effective vibration v ₑ ff<0.2mm/s) indoor space

Protective measures: Keep the original packaging to prevent corrosion and avoid close contact with electronic data media and pacemaker wearers (strong magnetic interference)

2. Installation and fixation (Chapter 4)

Preparation before installation:

Surface treatment: Thoroughly remove the anti-corrosion agent at the shaft end with commercial solvents to avoid affecting the transmission fit

Environmental verification: Confirm that the installation location temperature and altitude meet the requirements, and prohibit use in explosive hazardous areas

Installation operation:

Fixed specification: Use hexagon socket head screws with a strength grade of ≥ 8.8, tighten the flange evenly, and avoid deformation

Gap requirement: At least 100mm gap should be reserved between three sides of the motor and adjacent components to ensure heat dissipation and maintenance space

Special installation: When installing vertically (with the shaft end facing upwards), it is necessary to prevent liquid from seeping into the upper bearing; Motors with integrated brakes are prohibited from bearing axial forces

Balance requirement: The motor with keyway has been balanced with a semi guide key before leaving the factory. If transmission components are installed, they need to be re balanced as a whole according to ISO1940

3. Electrical Connections (Chapter 5)

Safety prerequisite:

Voltage risk: When the rotor rotates, the terminal voltage of the motor can reach 300V. Electrical work must be disconnected first, following the EN 50110-1 (DIN VDE 0105-100) standard

Static protection: Encoders and temperature sensors are static sensitive components, and touching the terminals with live hands/tools is prohibited

Wiring specifications:

Cable requirements: It is recommended to use Siemens prefabricated cables that are compatible with current and voltage. Both power and signal lines must be shielded (to prevent electromagnetic interference)

Plug operation:

Power plug: size 1 for 1FK6 03. -100 (torque ≤ 12Nm), size 1.5 for 1FK6 101/103 (≤ 20Nm)

Signal plug: compatible with encoder and temperature sensor, torque ≤ 12Nm

Operation taboos: The output direction of the plug can be adjusted up to 10 times, and excessive twisting is prohibited to cause cable damage

Brake wiring: Connected through a power plug, powered by 24V DC ± 10%, only used for emergency stop (cannot be used as a working brake)

Grounding requirement: PE conductor must be connected to ensure effective protection function

4. Startup and Debugging (Chapter 6)

Pre startup inspection:

Wiring verification: All plugs are securely fastened and not loose; The cable has no protruding wires, and the inside of the plug is clean and dry

Protection activation: All protective devices of the motor (temperature sensors, thermal overload relays, etc.) are in working condition

Mechanical inspection: The drive system is not stuck, the shaft end key (if any) is fixed to prevent swinging, and the tension of the transmission parts (such as belts) is adapted

Brake test: Apply 24V DC ± 10% to the BR and BR2 pins to confirm that the rotor rotates freely without any frictional noise

Start operation:

Unlock the brake (if necessary) and complete the system linkage according to the converter (such as SIMODRIVE) manual

Confirm that the maximum speed of the motor (n ₘₐₓ) does not exceed the nameplate markings to avoid operating at excessive speeds

Monitoring operation status: surface temperature not exceeding 140 ℃, no abnormal vibration or noise

System integration: Complete positioning, speed regulation and other functional debugging according to device requirements to ensure stable coordination with the converter

5. Maintenance and troubleshooting (Chapters 7-8)

Routine maintenance:

Cleaning requirements: Regularly clean the surface of the motor according to the degree of on-site pollution to ensure smooth heat dissipation

Wear life of vulnerable parts: about 5000 hours for radial shaft seals (oil lubrication) and 20000 hours for bearings (guidance value)

Special note: After disassembling the motor, the encoder system must be recalibrated before it can be used again

Common troubleshooting:

Core causes of fault phenomena and solutions

Insufficient shielding of irregular motor/encoder cables during operation; Check for shielding and grounding when the controller gain is too high; Adjust the controller according to the converter manual

Abnormal vibration transmission components/unbalanced load; Poor alignment of the drive chain; Loosening of fixing screws and rebalancing; Correction alignment; Check and tighten the screws

Foreign objects inside the motor with abnormal noise during operation; The manufacturer specializes in repairing damaged bearings and prohibits self disassembly

Motor overheating (surface temperature>140 ℃) and load overload; Heat dissipation obstruction (dust accumulation), load verification (refer to nameplate); Clean the surface and ensure the flow of cooling air

6. Disposal and scrapping (Chapter 8)

Scrap standard: Follow national and local environmental regulations, dispose of according to standard recycling procedures, or return to Siemens manufacturer

Special disposal: Encoder electronic components need to be treated separately as electronic waste to avoid environmental pollution

Data retention: Product nameplate data needs to be retained with the equipment for subsequent maintenance and traceability

Safety regulations and important tips

1. Core security risks and protection

Electrical risk: Before operation, power must be cut off, tested, and grounded to prevent electric shock from the 300V terminal voltage

Hot air hazard: The maximum temperature on the surface of the motor is 140 ℃. It is forbidden to touch high-temperature surfaces, and temperature sensitive components should be kept away from them

Mechanical risk: Protective devices need to be installed when the rotor rotates, and the shaft end key needs to be fixed to prevent it from being thrown out; Do not collide with the shaft end and bearing

Magnetic interference risk: The rotor contains strong magnetic permanent magnets, and pacemaker wearers need to stay away from the disassembled rotor; Electronic data media should be kept away from proximity

Installation taboos: It is prohibited to directly connect to the three-phase power grid (which may cause damage to the motor), and must be driven through the configured converter

2. Key standards and compliance requirements

Product compliance: Compliant with EN 60034 series standards, 73/23/EEC low voltage directive, standard motor with UL certification (nameplate marked UR)

Operating standards: comply with EN 50110-1 (Electrical Work Safety), ISO1940 (Balance Standards), etc
