Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
Engineered to handle high-inertia industrial loads with high precision, the Mitsubishi Electric HG-SN102BJ-S100 AC servo motor delivers stable torque output and reliable performance within modern manufacturing systems. Operating at a rated output of 1.0 kW and a rated speed of 2000 r/min, this model is built with an integrated electromagnetic safety brake and a factory-installed oil seal to prevent fluid ingress, making it well-suited for demanding environmental conditions.

The "BJ" suffix specifies both an integrated brake ("B") and an oil seal ("J"). While standard models like the HG-SN102 are physically compatible in terms of frame size and shaft dimension, switching to a non-B or non-J variant will require modification of the PLC control safety circuit and may compromise seal protection in wet environments. Confirm that your drive parameter set matches the S100 special specifications configuration if replacing a customized factory-run motor.
Maintain a load-to-motor inertia ratio of 15 times or less. Exceeding this limit leads to positioning overshoot, loop instability, and recurring overcurrent faults (such as AL.50 or AL.30 on associated MELSERVO drives). If your system demands high deceleration frequencies under high-inertia loads, integrate an external dynamic braking or regenerative resistor array to protect the drive's internal capacitors.
Always suppress voltage spikes from the 24VDC electromagnetic brake by wiring a surge-absorbing varistor in parallel with the brake coil. Do not share the 24VDC brake power supply with the PLC controller's I/O power circuit, as switching inductive brake loads introduces electrical noise that can drop local control rails or cause intermittent encoder communication faults.
Mount the motor on a flat, rigid metal surface designed to act as a heat sink. Ensure the mating surface is clean of debris, paint, and rust protectants.
Verify shaft alignment to avoid excess radial and axial loads. Use a flexible coupling rated for high-torque servo operation to prevent mechanical fatigue on the motor bearings.
Route cables with a continuous drip loop if liquid runoff is expected near the connectors. Ground the motor frame securely to the main electrical panel ground plate using a heavy-gauge, low-impedance grounding strap.
