Wiring specifications:

Cable cross-section: power cable ≥ 2.5mm ² (2.5mm ² corresponds to 21A), signal cable 0.5mm ²;

Grounding: The protective grounding wire (PE) needs to be directly connected to the power module, and the shielding layer needs to be grounded 360 ° (using EMC clamps);

Terminal box: Conventional terminal box TB3R61 (maximum capacity for 240mm ² cable), optional 1XB7750 (maximum capacity for 300mm ² cable).

2. Maintenance points

Bearing maintenance:

Re lubrication interval: 4000 hours for 2-pole motors on 400 frames, 6000 hours for 4-8 pole motors; 3000 hours for 2-pole motors on 450 frames, 6000 hours for 4-8 pole motors;

Lubricating grease type: It is recommended to use Siemens specified lubricating grease, with a replenishment amount of 1/3-1/2 of the internal space of the bearing;

Status monitoring: SPM impact pulse measurement interface (Q01) can be optionally installed to monitor bearing vibration in real time.

Routine inspection:

Cycle: There is no fixed cycle, and the following situations need to be checked: motor abnormal noise, increased vibration, increased current, and surface temperature exceeding 120 ℃;

Content: Clean up foreign objects on the surface of the motor, check the cable shielding layer, verify the temperature sensor signal, and confirm that there are no leaks in the cooling circuit.

Scrap and Compliance

Scrap process:

Power off and wait for the DC bus to discharge (≥ 60s), cool the motor for more than 30 minutes;

Drain the cooling circuit (if necessary) and clean the chips/dust inside the motor;

Disassemble in reverse order of installation (first remove primary components, then remove secondary components);

Classified recycling: Metal components (iron/aluminum), electronic components (windings/cables), insulation materials, permanent magnet components need to be magnetized at 300 ℃ or above for 30 minutes.

Compliance requirements:

Compliant with EN 10204 (Material Certification), EN ISO 12944-5 (Anti Corrosion Coatings), RoHS (Restriction of Hazardous Substances);

Waste packaging: PE-HD/PE-LD/PP/PS materials are recyclable, and wood can be incinerated.
