Product Description:

The KSM02.1B-071C-35N-M1-HP0-ET-S3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By uniting a size 071 synchronous motor with drive electronics, it removes the need for long motor cables and centralized cabinets. The unit is intended for precise, decentralized axis control in packaging, material-handling, and assembly systems. This layout is useful on moving carriages and other distributed machine sections where cable motion and enclosure space must be kept to a minimum.

The drive draws from a bus of DC 750 V, so it can share a common supply with other high-power axes. Thermal energy leaves the housing through natural convection, eliminating fans and reducing service parts. Position feedback is handled by a Hiperface optical encoder that provides 128 signal periods per mechanical revolution, and its data are stored as a Multi-turn absolute value for position retention after a power cycle. This encoder arrangement supports both commutation and position monitoring during repeated start-stop operation. The integrated motor uses winding code 35 with length C, and the unit is assigned to Basic performance in Series 2, Version 1.

Field wiring is consolidated by a Hybrid Connector that routes power, feedback, and Ethernet through one interface. Motion commands and diagnostics travel over Multi-Ethernet, providing real-time communication with compatible controllers. Integrated safety functions comply with Safe Motion (without SBC), allowing safety-related drive functions to be handled inside the unit. Mechanical output is delivered through a shaft with a keyway, and a shaft seal protects the bearings. The compact housing supports direct installation at the axis where available mounting space is limited. The drive is supplied without a holding brake, so an external device or axis mechanics must hold the load when power is removed.
