Product Description:
The KSM01.2B-071C-35N-S1-HG2-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining the servomotor, power electronics, and decentralized control in one enclosure, the unit simplifies cabinet layouts and shortens field wiring. It is intended for distributed motion axes in conveyors, pick-and-place modules, and packaging stations where compact drive assemblies reduce installation time and lower electromagnetic interference. The product merges torque generation and inverter functions at the machine frame, reducing the need for intermediate terminal strips.
It operates from a DC 750 V bus that reaches the housing through a single Hybrid Connector, which carries power, control, and protective earth pins in one molded shell. Heat produced by the embedded drive stage is dissipated by natural convection, so external fans or liquid loops are unnecessary. Deterministic command and status data move across SERCOS 2 (RS422), allowing tight cycle synchronization with higher-level controllers. Position feedback is accepted through a Hiperface interface, and the optical encoder works with winding code 35, motor size 071, and length C to support the basic performance level. This configuration follows the standard design option, uses design version 2, includes a shaft seal, and omits additional safety technology.
Building on that electrical and mechanical layout, the encoder delivers 128 signal periods per revolution and provides single-turn absolute values for precise indexing. Mechanical holding torque is provided by an electrically released brake that clamps the rotor when de-energized and is powered by DC 24 V during normal motion. A plain shaft transmits torque directly to the load and allows couplings or pulleys without keyways. The integrated arrangement places the drive close to the working axis and helps keep external wiring short.
