Product Description:

The KSM02.1B-071C-24N-M1-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor with an onboard controller, it simplifies decentralized installation on machinery and supports distributed motion axes in automated lines and packaging equipment. The unit’s 071 frame and C length correspond to its torque and inertia class, while the integrated electronics accept high-voltage DC bus power to regulate speed and position through closed-loop feedback.

The drive operates from a supply of DC 750 V, allowing it to share a common bus with other converters and regenerate energy during braking. Heat is removed through natural convection, so no additional fans or liquid circuits are required for continuous duty within its specified ambient range. Position data is provided by a Hiperface interface that exchanges absolute multi-turn information between the optical encoder and the controller at power-up. Command and diagnostic traffic pass over Multi-Ethernet, enabling selection between PROFINET, EtherNet/IP, or EtherCAT without hardware changes. For functional safety, the integrated output stage supports Safe Torque Off (STO), which disables motor power through redundant channels when a protective device is triggered.

Mechanical holding is managed by an electrically released brake that clamps the shaft when control voltage is removed. It is powered by DC 24 V supplied through the single-cable Hybrid Connector that carries power, signals, and Ethernet to the module. The optical scanning system resolves each revolution into 128 signal periods, and multi-turn counting preserves absolute feedback after power loss. A shaft with keyway mates to standard couplings, and a positive shaft seal prevents lubricant egress into the electronics compartment. The design option is standard, the design version is 1, and the basic performance level is suitable for indexing tables, pick-and-place gantries, and light-duty actuators that benefit from integrated drives without cabinet-mounted amplifiers.
