KSM02.1B-061C-35N-M1-HP0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

Bosch Rexroth Indramat's KSM02.1B-061C-35N-M1-HP0-ET-S3-D7-NN-FW belongs to the KSM Motor Integrated Servo Drives series. As a motor-integrated servo drive, it combines power electronics, feedback, and an electronically commutated motor in one housing to provide decentralized axis control for machines and conveyors. This arrangement reduces the amount of wiring between the control cabinet and the motor. It also supports coordinated position, speed, and torque control in modular industrial automation cells.

Electrical power is supplied through a DC link rated at 750 V DC, allowing several drives to operate from a shared intermediate circuit. Heat is removed through natural convection, eliminating the need for cooling fans and their associated maintenance. Command and diagnostic data are exchanged through Multi-Ethernet, which supports EtherNet/IP, PROFINET, and EtherCAT communication. Rotor position is measured by a Hiperface optical encoder that provides 128 signal periods per revolution in a multi-turn absolute format. This feedback arrangement allows the controller to retain position information across operating cycles without requiring a new reference procedure after every power interruption. Winding code 35 identifies the stator configuration used for the continuous torque characteristics of this model. The drive has a standard configuration, design version 1, a basic performance level, and a Series 2 design.

The unit uses a 061 frame with motor length C, providing a compact envelope for decentralized installation near the driven axis. Power, control, and brake conductors pass through a hybrid connector, reducing the number of separate plugs and cable runs required on the machine. Torque is transmitted through a shaft with a keyway and shaft seal; the keyway provides positive engagement with the coupling, while the seal helps protect the bearings from dust and coolant. Integrated Safe Motion without SBC provides supported safe-stop and safe-torque-off functions without Safe Brake Control. The assembly is supplied without a holding brake, so a load-side locking device is required when a vertical axis must remain stationary after motor torque is removed. The sealed motor and drive housing also keeps the electronic and electromechanical components together at the machine axis, limiting the need for separate drive hardware inside the control cabinet.
