Product Description:

The KSM02.1B-061C-61N-M1-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet servomotor with decentralized drive electronics, the unit supplies torque and closed-loop control near the machine axis, simplifying cabinet wiring in distributed industrial automation cells. It is intended to position tooling, conveyors, and auxiliary axes where space savings and reduced cabling are important.

In operation, the drive is powered from a regulated DC 750 V bus that is daisy-chained to adjacent axes. Power, control, and safety lines are routed through a single Hybrid Connector, so one plug carries the DC link, logic supply, and fieldbus. Thermal management relies on natural convection, so the aluminum housing must be mounted in free air to dissipate losses without fans. Position feedback is generated by a Hiperface optical encoder with 128 signal periods per revolution. Its multi-turn absolute design records revolutions mechanically, so homing routines are unnecessary after power cycles. Because the module is delivered without a holding brake, static loads must be supported by external means, and a shaft seal keeps contaminants away from the front bearing.

For networked motion systems, command data reaches the unit over Multi-Ethernet, allowing synchronous operation on Sercos III, EtherNet/IP, or PROFINET without hardware changes. When an emergency stop is needed, the integrated Safe Torque Off (STO) circuit disconnects gate drives so motor torque falls to zero. Mechanically, the drive uses a shaft with a keyway and is built in size 061 with length code C, which suits pick-and-place stations. The unit has the standard design option, design version 1, a basic performance level, Series 2 construction, and winding code 61. A positive shaft seal blocks coolant splash, and the lack of internal fans reduces acoustic noise during operation.
