KSM02.1B-061C-35N-M1-HG0-ET-SD-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HG0-ET-SD-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining power electronics and a synchronous motor in one housing, it decentralizes motion control and streamlines wiring on conveyor segments, pick-and-place stations, and small gantries. The device belongs to Series 2, has design version 1, and offers a Basic performance level. Motor size 061 and length C establish its mechanical envelope and torque class. Its external master communication option provides direct Multi-Ethernet networking with higher-level PLCs.

A regulated bus voltage of DC 750 V feeds the inverter stage, eliminating the need for separate AC drives in centralized cabinets. Field connections use a single hybrid connector that carries power, control, and feedback conductors in one molded plug, reducing the number of installation points. Heat is removed by natural convection, so no fans are required. The servo position loop operates through a Hiperface interface, and the incremental track provides 128 signal periods per mechanical revolution to support smooth velocity control at low speeds. Winding code 35 identifies the stator configuration used for the intended current and torque range. The unit is supplied without a holding brake, so an external clamp or another suitable mechanism must retain static loads when drive torque is unavailable.

Position feedback uses an optical scanning method for accurate detection of rotor movement. A multi-turn absolute encoder tracks shaft position across multiple complete rotations without requiring battery backup. Integrated Safe Motion with SBC supports certified monitoring of speed and stopped states without additional safety relays. Power is transmitted through a plain shaft, while a shaft seal helps limit the entry of dust or coolant around the bearing journal. The integrated housing allows the drive to be installed near moving axes, reducing long motor cable runs and the amount of equipment required in the central control cabinet.
