Product Description:
The KSM02.1B-071C-35N-S1-HP2-ET-L3-D7-NN-FW is an integrated servo drive produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By merging a permanent-magnet motor with drive electronics, the unit simplifies wiring and reduces panel space in distributed automation architectures. It is intended for positioning and speed-regulated tasks on packaging machines, handling modules, and similar equipment where coordinated multi-axis motion is required. That arrangement supports decentralized machine layouts by placing the drive function at the axis instead of in a separate cabinet.
This model operates from a bus supply of DC 750 V, and the single-cable system uses a Hybrid Connector that carries power, signals, and safety conductors in one sheath. Heat is removed by natural convection, so clearance around the housing is necessary when planning enclosure layouts. Position feedback is handled by a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution, giving the controller incremental and absolute data for tight speed loops. The encoder is single-turn, and winding code 35 is used with the basic performance level for moderate torque demands. Because cooling relies on ambient airflow, the housing should not be enclosed in a tight, unventilated space.
Motion commands and diagnostic traffic are exchanged through a Multi-Ethernet interface, enabling network selection among EtherNet/IP, PROFINET, or EtherCAT without hardware changes. The electrically released brake is energized by DC 24 V to hold the rotor when power is removed, and its presence is complemented by Safe Torque Off (STO) circuitry for machine safety functions. The frame size is 071, and the shaft has a keyway and an integral shaft seal to support torque transmission while helping keep contaminants out. The unit uses Series 2 electronics, motor length C, and a standard design option. These features suit compact servo axes that need integrated drive control, onboard braking, and flexible network connectivity.
