Product Description:

The KSM02.1B-071C-24N-M1-HG2-ET-L3-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 drive electronics and a 071-frame synchronous motor in a single enclosure, the unit decentralizes motion control and reduces cabinet wiring. It is intended for distributed automation tasks such as positioning on conveyors, gantry axes, or compact tooling stations where space is limited. This arrangement also avoids a separate motor cable between a remote inverter and the machine axis.

Electrical power reaches the unit through a DC 750 V bus, allowing high acceleration capability without local rectifiers. A single Hybrid Connector merges power, fieldbus, and safety conductors, minimizing separate terminations and helping preserve ingress protection. Rotor feedback communicates via Hiperface; its optical code disc provides 128 signal periods per revolution so the controller can interpolate fine incremental data for accurate velocity control. That feedback also supports stable commutation and responsive speed regulation during repeated motion cycles. Thermal dissipation is handled by natural convection, so the housing must be installed where air can move freely along the cooling ribs.

Control integration is achieved through Multi-Ethernet, enabling the same hardware to participate in several real-time Ethernet networks without changing option cards. Functional safety is provided by the built-in Safe Torque Off (STO) channel that disables the power stage on demand. An electrically released brake holds the axis when power is removed and disengages at DC 24 V. The plain shaft is protected by a shaft seal, and the C-length 071 frame pairs with winding code 24 for the basic performance level used in Series 2 devices. Design version 1 and the standard mechanical option keep the mounting envelope consistent with adjacent KSM nodes.
