Product Description:

The KSM02.1B-061C-35N-S1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor with integrated electronics in one housing, it reduces the amount of cabinet wiring and helps keep decentralized motion axes compact. This arrangement places motor and drive functions directly at the axis, which can simplify machine layouts where cabinet space is limited. The unit uses frame size 061, length C, and winding code 35, making it suitable for pick-and-place heads, gantries, and secondary packaging stations. In automated cells, it converts DC bus energy into controlled torque and position under PLC supervision.

The servo module is supplied from a DC 750 V common bus, so multiple axes can share a single rectifier stage and exchange energy through the same DC link. Power, feedback, and safety wiring enter through a Hybrid Connector, which keeps the connection arrangement compact at the housing and reduces the number of separate cable entries. Heat from the inverter section is removed by natural convection, so no internal fan is required. Rotor position is measured by a Hiperface optical encoder with 128 signal periods per revolution, providing stable feedback for velocity control and precise position correction. The feedback channel also supports smooth commutation during continuous motion.

Field integration is handled by the drive’s Multi-Ethernet interface, allowing the same hardware platform to communicate with common industrial Ethernet networks. Functional safety is provided by Safe Motion (with SBC), which supports safe stopping functions inside the drive. The unit uses the standard design execution and design version 1. The output uses a plain shaft with a shaft seal, so couplings or pulleys can be mounted directly while grease loss is limited. The unit is supplied without a holding brake, so static load holding must be provided externally and the arrangement is best suited to axes that do not rely on a brake at standstill.
