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...
Integrating directly into the MELSERVO-J4 motion control architecture, the Mitsubishi Electric HG-SR202J provides precision rotary control for heavy-duty industrial positioning systems. This medium-inertia AC Servo Motor delivers a rated output of 2.0 kW, operating at a rated speed of 2000 r/min. Designed with an integrated oil seal (indicated by the J suffix), it provides reliable performance in environments where exposure to machine lubricants is common, safeguarding internal windings and bearings from ingress.

The HG-SR202J model serves as the drop-in oil-sealed counterpart to the standard HG-SR202. While mechanically compatible in mounting layout, the J-variant features a specialized shaft faceplate to accommodate the sealing lip. This motor is natively matched with the MR-J4-200A and MR-J4-200B servo amplifiers; running it with under-rated drive stages will trigger fault alarms and limit torque output.
To guarantee optimal heat dissipation, this motor must be mounted on a high-thermal-conductivity metal framework (equivalent to an aluminum heat sink of at least 300mm x 300mm x 12mm). In enclosed, unventilated compartments, monitor temperature rise carefully; the Class 155 (F) insulation protects the windings, but excessive heat can degrade bearing grease and compromise the long-term effectiveness of the physical oil seal.
Avoid dry-running the motor at high speeds during initial commissioning. The integrated oil seal lip requires a small amount of lubrication to prevent thermal friction wear; ensure a thin layer of compatible synthetic lubricant is applied. Separate the encoder feed from main power conductors by at least 100mm to prevent electromagnetic noise induction, and always verify that the grounding terminal is bonded directly to the main system chassis.
Align the motor shaft precisely with the load coupling to minimize radial and axial forces on the bearings.
Torque all mounting bolts to specified tightening metrics in a diagonal cross-pattern.
Secure the power and encoder cables, ensuring standard IP-rated connectors are fully sealed.
Establish protective earth connections before applying control voltage.
