Product Description:

The KSM02.1B-071C-35N-S1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat that sits within the KSM Motor Integrated Servo Drives series. By embedding power electronics, feedback, and a synchronous motor into one enclosure, the device supplies decentralized motion control to conveyors, pick-and-place axes, and other automation lines. It is intended for layouts that place drive electronics close to the motor. This integrated layout helps where cabinet space is limited.

Its combined power and feedback line uses a Hybrid Connector, which cuts cabling and speeds installation. The drive relies on natural convection, so no fan or coolant loop is required. A DC 750 V bus feeds the integrated inverter and matches decentralized supply rails. Position data moves through Hiperface; the optical reader resolves the scale into 128 signal periods for accurate interpolation. Communication uses Multi-Ethernet and supports Sercos III, EtherNet/IP, or PROFINET on the same hardware. Frame size 071 and motor length C set the torque density and thermal mass, while the module follows the standard design option, design version 1, series 2, and a basic performance level.

The mechanical interface uses a plain shaft, so torque is transmitted through couplings rather than keyed engagement. A shaft seal is present on the output end to limit lubricant splashes and fine dust from entering the bearing chamber. Because the drive is supplied without a holding brake, it cannot clamp a vertical load at power-off, and external locking devices are needed. The encoder is single-turn, providing absolute position within one revolution for homing-free startups. The unit has no integrated functional safety circuits. The winding code 35 sets the current, resistance, and inductance values for the integrated motor.
