Product Description:

The KSM01.2B-071C-10N-S1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat and supplied in the KSM Motor Integrated Servo Drives series. As a compact unit that merges drive electronics with the servomotor, it simplifies cabinet wiring and supports decentralized motion axes on assembly lines, packaging machines, and material-handling stations. This layout places the power electronics close to the axis, which shortens motor cable routing and helps keep distributed machine sections compact. Because the inverter and motor share one housing, the unit is well suited for machine modules where long motor leads would be inconvenient. It can be mounted directly on the machine structure, which helps distribute drive functions across separate stations instead of concentrating them in one control cabinet.

Electrical power is supplied through a DC 750 V intermediate circuit, and both power and control conductors are combined inside a hybrid connector, reducing cable count and simplifying cable routing. Heat from the embedded power stage is removed by natural convection, so no external fans are required. Position feedback comes from a Hiperface optical encoder that provides 128 signal periods per revolution. The feedback device is single-turn, so absolute position is retained within one shaft revolution only. The motor section uses size code 071 with length code C, and the unit has the basic performance level with the standard design option in design version 2. A shaft seal is fitted to help limit ingress when the unit is mounted outside sealed cabinets.

Axis control data are exchanged with the master via SERCOS 2 (RS-422), allowing deterministic velocity and torque commands without additional gateway hardware. The communication link supports synchronized control in automated equipment where command timing matters. Mechanical power is transmitted through a plain shaft, and braking torque must be supplied externally because the drive is supplied without a holding brake. That arrangement is suitable for axes that use an external holding method when the load must remain fixed at standstill.
