KSM02.1B-061C-35N-M1-HG0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, drive electronics, and feedback in a sealed unit, it provides decentralized motion control for packaging stations, material-handling gantries, and conveyor modules. The compact unit mounts directly on the machine frame, reducing the amount of wiring routed to a central control cabinet. It can operate with other compatible axes connected to a common DC bus in an automated machine.

Electrical power is supplied through a 750 V DC link that can be shared with other axes on the same bus. A single hybrid connector carries power, communication, and control signals, reducing the number of separate cable connections required at the motor. Heat from the power stage is dissipated through natural convection, eliminating the need for cooling fans or liquid circuits. The Multi-Ethernet interface supports PROFINET, EtherNet/IP, and EtherCAT communication without additional interface hardware. Integrated Safe Motion functions provide speed and position supervision without a safety brake controller. A shaft seal helps prevent coolant and dust from reaching the front bearing while preserving the enclosure protection needed around industrial machinery.

The feedback system uses a Hiperface optical encoder that produces 128 signal periods per revolution. Its multi-turn absolute capability retains position information across power cycles, allowing the axis to resume operation without a homing routine. The unit has a 061 frame, motor length C, winding code 35, and a basic performance profile. Its plain shaft provides a smooth output interface for a clamping coupling, while the shaft seal protects the bearing area. The motor follows the standard design option and uses the Series 2 platform with design version 1. Because it is supplied without a holding brake, an external mechanical brake or another suitable restraint must secure vertical loads whenever drive power is removed.
