Product Description:

The KSM02.1B-061C-35N-M1-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a servo motor, power stage, and fieldbus interface in one enclosure, it shortens cabinet wiring and supports decentralized motion tasks in packaging, woodworking, and assembly stations. The device delivers precise torque and position control directly at the machine frame, which helps keep the feedback loop close to the mechanical load. This arrangement also reduces the number of separate components that must be mounted elsewhere in the system.

It operates from a DC 750 V shared bus, so drive power is supplied through a single high-energy link rather than through separate local inverters. Motor power and communication reach the unit through a hybrid connector, which carries DC power, signals, and safety wiring in one plug. Heat generated by the power stage is removed by natural convection, so no fan is required. High-resolution feedback is provided by a Hiperface interface with 128 signal periods, giving the controller fine position information for smooth velocity regulation. The unit is built in Generation 2 with version 1 electronics, and it uses size 061, length code C, and winding code 35.

The drive is supplied with no holding brake, so vertical axes must secure loads mechanically when power is off. Motion commands are exchanged over Multi-Ethernet, allowing the same node to operate on SERCOS III, EtherNet/IP, or PROFINET networks without hardware changes. For stop-category 0 requirements, the integrated Safe Torque Off (STO) function disables the power devices through certified logic. A plain shaft couples directly to gearboxes, and a shaft seal is fitted to help limit ingress when the motor is mounted in coolant spray areas. The basic performance level, optical encoder technology, and multi-turn absolute capability allow position retention over multiple turns without a battery.
