Product Description:

The KSM01.2B-071C-35N-M1-HP2-SE-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. It combines a size 071 synchronous motor, inverter stage, and multi-turn feedback in one housing, so distributed machine axes can be powered from a DC bus without a separate control cabinet. The device controls position, velocity, and torque directly at the machine frame. Because the inverter electronics are mounted on the motor, the axis can be installed closer to the load and cable runs can be shortened. This layout suits modular conveyors, pick-and-place gantries, and light assembly cells where compact axis hardware is preferred.

A single hybrid connector carries the DC bus, logic supply, and real-time communication to the drive. The power section accepts DC 750 V and removes internal heat through natural convection, which eliminates forced-air components. Position data come from an optical encoder with a Hiperface interface that provides 128 signal periods per revolution for interpolation in the controller. The unit uses the standard design option and design version 2, while motor length C and winding code 35 are paired with the series 1 basic performance configuration. This arrangement supports decentralized motion hardware where enclosure space and fan maintenance need to be kept low.

The electromechanical brake is electrically released and spring-clamped when power is removed, and it is energized by DC 24 V from the machine safety circuit. The brake helps hold the axis at standstill when operating power is off. Command data and diagnostics are transmitted over the SERCOS 2 (RS-422) master interface for cycle-synchronous control. Multi-turn absolute feedback retains position information without a homing move, and optical sensing avoids magnetic drift over time. The output uses a shaft with a keyway for positive coupling, and an integral shaft seal helps block contamination at the flange.
