Product Description:

The KSM02.1B-076C-35N-S1-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. This product combines a synchronous motor, optical feedback, and power electronics in one enclosure, enabling decentralized motion control without a cabinet-mounted drive. It mounts directly on machine frames to deliver precise torque and speed regulation for automated equipment. This arrangement also reduces the need for a separate axis amplifier and keeps the inverter stage close to the motor.

It operates from a supply bus of DC 750 V, allowing the integrated inverter stage to draw high-voltage DC directly from a common line. Power, signal, and network leads are combined in a single Hybrid Connector, which simplifies wiring between adjacent axes. Heat generated during service is dissipated through natural convection, so no fans or liquid lines are required. A single-turn optical encoder communicates over the Hiperface interface and resolves each revolution into 128 signal periods, supporting tight velocity and position loops. The device is design version 1 with a standard mechanical option, and motor length C works with winding code 35 for this configuration.

Control commands are exchanged over Multi-Ethernet, letting the drive join Ethernet-based fieldbus networks without additional interface cards. Functional safety is provided by Safe Torque Off (STO), which disables the power stage for safety-related stopping functions. The rotor ends in a plain shaft, and a shaft seal helps limit ingress, but the unit is supplied without a holding brake, so external restraint is needed when power is removed. The motor size is 076, and the optical encoder uses a single-turn format that reports position within one mechanical revolution.
