Product Description:

The KSM02.1B-071C-35N-M1-HG2-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the decentralized KSM Motor Integrated Servo Drives series. By combining the motor and drive electronics in one housing, the unit shortens cabinet wiring and supports installation close to the driven mechanism. It is intended for axes that require precise torque and position control in industrial automation lines. Its integrated layout also reduces the amount of separate hardware needed between the power stage, the feedback path, and the machine axis. This arrangement supports decentralized motion systems where compact installation and direct axis integration are important.

A Hybrid Connector carries power, feedback, and network conductors through one plug, which helps keep external cabling compact. Thermal management relies on natural convection, so no external fan is required under typical operating conditions. The internal position loop uses a Hiperface optical encoder that provides 128 signal periods per revolution and multi-turn absolute position data. An electrically released holding brake secures the shaft when the axis is de-energized. The motor has frame size 071, length code C, and winding code 35. A shaft seal is fitted to limit lubricant loss and help keep particulates away from internal components.

The electrical section connects to a shared bus rated at DC 750 V, and the brake circuit uses DC 24 V for coil release. Motion commands and diagnostics are exchanged over Multi-Ethernet, allowing the unit to operate with EtherCAT, PROFINET, or EtherNet/IP network structures. Functional safety is handled by Safe Motion (with SBC), which supports certified stop functions without separate relay-based wiring. The shared bus arrangement supports common power distribution across multiple motion modules. This unit is supplied in the standard design option, uses design version 1, and has the basic performance level. It is part of Series 2.
