Product Description:

The KSM01.2B-061C-61N-M1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines the inverter electronics, feedback hardware, and motor into one housing, which reduces separate cabinet components and shortens machine wiring. This arrangement is useful in automated handling stages, packaging axes, and material transfer stations where compact installation and fewer connection points are preferred. Because the drive and motor are combined, the unit can be mounted close to the driven axis and helps reduce the need for long motor cable runs.

A nominal bus supply of DC 750 V feeds the inverter section through a single Hybrid Connector that carries power, signals, and protective earth. Motion commands travel over the SERCOS 2 (RS422) master link, while position data come from an optical encoder with 128 signal periods per revolution and Hiperface communication. The optical system helps maintain accurate feedback with low drift during operation. Its multi-turn absolute function retains shaft position information across power cycles, so the axis can often restart without a homing routine. The combined connector layout also keeps the cable set compact on moving machine sections.

The motor uses frame size 061 and a plain shaft, and a shaft seal helps block dust or fluid ingress at the output end. Cooling is done by natural convection, so no external blower is required and installation remains simple around the axis. The drive is supplied without a holding brake, so static position must be maintained by servo torque or an external clamp when power is removed. This layout is suitable for axes where standstill holding is handled elsewhere in the machine. The unit is design version 2 with the standard option set, and it belongs to Series 1.
