SIEMENS SIMOTICS L-1FN3 series linear motor

Grounding: The PE wire is directly connected to the power module, and the cable shielding layer is extensively grounded without using core wire insulation (withstand rated voltage).

Specific connection:

Power cable: 4-core (PE=green yellow, U=black, V=black, W=black), core wire cross-section ≥ 2.5mm ² (2.5mm ² corresponds to max current of 21A, 16mm ² corresponds to max 66A);

Temperature sensor: KTY84 should pay attention to polarity (white=-, brown=+), Pt1000 should be wired according to the pins, and safety isolation should be achieved through TM120/SME12x;

Connector: 1FN3050 with fixed cable, 1FN3100-900 connected to cover plate with bolts, tightening torque M4=2.2Nm, M5=3.4Nm.

4. Debugging

Preconditions for debugging: Mechanical/electrical installation completed, cooling system functioning properly, and drive system functioning properly.

Key steps:

Checklist confirmation: including three types of inspections: general (component integrity/environment), mechanical (air gap/slider flexibility), and electrical (grounding/shielding);

Insulation resistance test: tested with ≤ 1000V DC, with a winding to PE impedance of ≥ 10M Ω for 60 seconds;

Cooling system inspection: Confirm that the coolant meets the requirements, the circuit pressure is ≤ 10 bar, and there are no leaks;

Trial operation: Limit current/speed, monitor commutation (correct UVW phase sequence), check temperature sensor response.

5. Operation and maintenance

Operation monitoring:

Normal parameters: current ≤ rated value, temperature ≤ 120 ℃, no abnormal noise/vibration;

Troubleshooting: Motor lockout (check overload/phase), abnormal heating (check cooling/winding), abnormal noise (check air gap/commutation), see the fault table for details.

Maintenance cycle: There is no fixed cycle, follow the following warning signs:

Foreign objects around the motor, machine abnormalities (visual/auditory), decreased positioning accuracy, and increased current consumption;

Coolant: Check/replace according to the requirements of the anti-corrosion agent manufacturer, and regularly flush the cooling circuit.

6. Scrapping and disposal

Scrap steps:

Power off → wait for DC bus discharge → cool down for 30 minutes;

Disconnect the cooling circuit (reduce pressure to 0 bar) → drain the coolant (compliant treatment);

Dismantle the cable (insulated power interface) → clean up foreign objects in the motor;

Disassemble in reverse order of installation (first disassemble the primary components, then disassemble the secondary components in sections).

Waste disposal:

Secondary components: need to be demagnetized (300 ℃ ≥ 30min), and then classified and recycled (permanent magnets/metals/electronic components);

Packaging: PE/PP/PS is recyclable, wood is combustible, and municipal waste disposal is prohibited.
