Product Description:

Bosch Rexroth Indramat manufactures the KSM01.2B-076C-35N-M1-HP2-SE-NN-D7-NN-FW, an integrated servo drive belonging to the KSM Motor Integrated Servo Drives series. By combining motor, power electronics, and control logic in one enclosure, this unit minimizes cabinet wiring and simplifies installation on distributed machine axes. It is intended to deliver closed-loop motion in packaging lines, assembly stations, and other automation tasks where decentralizing the drive can shorten feedback paths and reduce panel heat load.

The drive’s DC bus accepts a maximum supply of DC 750 V, allowing long cable runs from a common power supply without significant voltage drop. Command and diagnostic data are exchanged through SERCOS 2 (RS422), so the unit can be synchronized to other motion nodes with sub-millisecond accuracy. Power, signals, and brake conductors enter through a single Hybrid Connector, reducing connection points and improving ingress protection on the machine frame. Thermal management relies on natural convection, so no fans are installed. Rotor position is captured through a Hiperface interface derived from an optical code disk that delivers 128 signal periods per mechanical revolution, supporting smooth velocity control at low speeds.

Mechanical configuration follows size 076 with length code C and winding code 35, giving torque characteristics suited to the platform’s basic performance level. The integrated brake is electrically released, so it holds the shaft when drive power is removed and releases when the coil is energized with DC 24 V. A continuous shaft seal is fitted, and the output side uses a shaft with a keyway to transmit torque to couplings or pulleys without slip. The shaft seal helps protect the encoder compartment from coolant and dust, and the brake supports vertical-axis applications.
