KSM02.1B-076C-35N-M1-HP0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HP0-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining the motor, power electronics, and feedback hardware in one enclosure, it provides a decentralized axis that reduces cabinet space and wiring in automated packaging, material-handling, and light assembly equipment. The device belongs to Series 2 of the platform and is intended for applications that require compact motion modules mounted directly on the machine frame.

The drive accepts a DC-link supply of 750 V DC, allowing it to share a common bus with other inverters. Thermal losses are removed through natural convection, eliminating the need for serviceable cooling fans. Power conductors, fieldbus lines, and Safe Torque Off channels enter the housing through a single hybrid connector, simplifying line-through installation on multi-axis gantries. Rotor position is reported over Hiperface, and one mechanical revolution is represented by 128 signal periods. This feedback resolution supports the current regulators as they control the motor with winding code 35.

The servo uses a Multi-Ethernet interface for controller communication, allowing EtherNet/IP, PROFINET, or EtherCAT to be selected without hardware changes. The feedback assembly uses an optical sensor with a multi-turn absolute track, retaining position information across power cycles without batteries. Integrated Safe Motion with SBC provides certified stopping and monitoring functions over the network. Mechanical output is provided by a shaft with a keyway, and a shaft seal helps limit the entry of contaminants. The unit has motor size 076 and length code C, creating a compact housing for direct machine mounting. It has the Basic performance level, the Standard design option, and design version 1. The drive is supplied without a holding brake, so an external mechanism or motor torque must secure a stationary load when necessary.
