Delivering high-torque drive capabilities to heavy-duty industrial machinery, the Mitsubishi Electric HC-SFS702BG1H 1/11 is a high-capacity, medium-inertia industrial servo motor. This unit integrates a powerful 7.0 kW motor with a built-in electromagnetic safety brake and a specialized G1H leg-type reduction gear featuring a 1/11 reduction ratio. Designed for applications requiring precise speed regulation and reliable torque multiplication, this robust motor ensures exceptional dynamic response and stable operation under heavy load variations.

When pairing this motor with Mitsubishi servo drives, ensure that the drive parameters are explicitly updated to reflect the 1/11 physical gear reduction. Failure to configure the electronic gear ratio correctly in the parameters will cause mismatch faults between command pulses and actual axis movement. For legacy systems, verify that your servo amplifier firmware fully supports the HC-SFS high-resolution feedback protocols.
Due to the massive 146 kg weight and heavy-duty torque multiplication of the G1H reduction unit, rigid mounting is mandatory. Mount this motor on a machined, stress-relieved steel baseplate to prevent vibration-induced shaft misalignment. Thermal expansion of the leg-mount gear casing under high continuous duty cycles must be accounted for to preserve alignment tolerances over time.
Always implement a dedicated external surge suppressor (diode or varistor) across the 24V DC electromagnetic brake power lines. The inductive kickback from releasing this heavy holding brake can otherwise inject high-frequency noise into the encoder's feedback run, leading to intermittent feedback errors. Route motor power and feedback cables in separate, shielded trays to minimize EMI.
Mechanically align and secure the leg-type mounting frame to the machine bed using high-tensile strength bolts torqued to the manufacturer specification.
Connect the protective earth (PE) ground terminal directly to the central electrical panel grounding busbar to prevent noise and grounding loops.
Wire the 3-phase power phases (U, V, W) using shielded motor cables, ensuring correct phase sequence alignment to prevent unexpected motor reversal.
Plug in the high-resolution feedback encoder and connect the 24V DC safety holding brake lead wires to their respective drive-controlled relay outputs.
