Product Description:

The KSM02.1B-071C-35N-S1-HP0-ET-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 permanent-magnet motor and inverter in one enclosure to support decentralized motion control on automated machinery. The unit uses motor size 071, length code C, and a basic performance level. It is design version 1 with the standard option, and it fits Series 2 distributed architectures while reducing cabinet wiring. Placing the power electronics near the axis also helps keep machine modules compact where installation space is limited.

The drive operates from a DC 750 V bus, allowing several axes to share the same power source. Heat is removed by natural convection, so the housing does not require fans or liquid cooling circuits. A single Hybrid Connector carries power, communication, and protective earth, which helps keep cabling compact at the machine. Position feedback is provided through Hiperface, and the encoder resolution of 128 signal periods supports stable velocity control when paired with winding code 35. A shaft seal protects the interior, and the basic winding provides rated torque without external cooling equipment.

Field communication uses Multi-Ethernet, allowing the axis to integrate with common industrial Ethernet networks. The encoder is single-turn, which suits applications where position is referenced during startup and only one mechanical revolution must be tracked absolutely. Torque is transferred through a shaft with keyway, providing a secure mechanical interface for couplings and driven elements. The keyed shaft helps resist slippage during repeated reversals and other high-inertia motion changes. The motor is supplied without a holding brake, so load retention during power-off must be handled by external clamping or drive-controlled torque.
