Engineered specifically for high-performance motion control, the Mitsubishi Electric HF-KP23B is a low-inertia AC rotary servo motor designed to interface seamlessly within the MELSERVO-J3 series platform. Operating on a 200V AC class power supply, this compact unit delivers a continuous rated output of 0.2 kW and integrates an internal electromagnetic holding brake to secure vertical or mechanical loads during power outages or system disablements. The high-resolution 18-bit encoder ensures ultra-precise feedback for demanding positioning architectures.

The HF-KP23B features an integrated holding brake, which is mechanically and electrically distinct from the standard, non-brake HF-KP23 model. When migrating or interchanging hardware, verify that the existing cabinet wiring has the brake control circuit routed. This model connects directly to standard MR-J3-20A or MR-J3-20B servo drives.
The integrated electromagnetic brake is strictly designed as a holding brake to prevent vertical axes from dropping when power is removed. Under no circumstances should it be used as a dynamic stopping brake to decelerate rotating machinery, as this causes rapid mechanical wear on the brake lining, rendering the unit inoperable. Ensure your configuration commands deceleration through the MR-J3 amplifier prior to de-energizing the brake coils.
To prevent electromagnetic interference (EMI) from disrupting the sensitive 18-bit encoder signals, run the motor power/brake leads and the encoder cables in separate shielded conduits. Ensure that the 24V DC brake excitation power supply is isolated and regulated, as voltage fluctuations below 21.6V DC can cause partial brake drag, leading to rapid motor thermal overload and subsequent overcurrent faults on the amplifier.
Mount the motor securely to a rigid metal frame. Heat is dissipated primarily through the mounting face, so ensure clean contact with the metal structure to prevent thermal performance degradation.
Align the output shaft precisely with the load coupling. Misalignments exceeding limits can stress the shaft bearings and reduce encoder longevity.
Connect the encoder cable, ensuring the quick-lock connectors are fully seated and sealed. Avoid applying structural load or sharp bends to the cabling adjacent to the strain relief boots.
Establish the 24V DC brake supply circuit, incorporating an external surge absorber (diode) across the brake terminals to clamp inductive voltage spikes when the brake relay is cycled.
