Product Description:

The KSM02.1B-061C-35N-M3-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor with an on-board drive, it decentralizes motion control and reduces panel wiring in automated machinery. This layout places the power electronics close to the axis, which can shorten motor cabling and reduce the amount of cabinet hardware needed in distributed machine designs. The unit is design version 1 with the basic performance level, and its size 061 with frame length C supports medium-power axes where compact installation and straightforward setup are important.

The drive operates from a DC 750 V supply, allowing direct connection to a shared DC bus for energy exchange between axes. Heat is removed by natural convection, so no forced air or liquid circuit is required with the standard housing. Position feedback uses a Hiperface interface with a capacitive multi-turn encoder, providing synchronized position data to the controller. For field networking, the master communication channel is Multi-Ethernet, permitting parameter access over PROFINET, EtherNet/IP, or EtherCAT without hardware changes. Safety functions use Safe Torque Off (STO), which interrupts power to the motor windings without affecting the encoder channel.

The rotor has a plain shaft with a shaft seal that helps block lubricant escape and dust ingress. Power, feedback, and network lines terminate on a Hybrid Connector, limiting installation to a single cable set. The combined connector layout also helps keep cable routing compact around moving assemblies and tight machine frames. The drive is delivered without a holding brake, so static load retention must come from external mechanics or the servo loop. Inside the encoder, resolution is fixed at 16 signal periods per revolution, and capacitive sensing supports stable operation during shock and temperature changes. Winding code 35 aligns the electromagnetic design with the series 2 electronics to meet torque targets for applications such as pick-and-place arms and indexing tables.
