KSM02.1B-076C-35N-M1-HP0-ET-S3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HP0-ET-S3-D7-TO-FW is manufactured by Bosch Rexroth Indramat and forms part of the KSM Motor Integrated Servo Drives series. Rated for basic performance in the Series 2 lineup, it combines a servo motor, drive electronics, and a fieldbus interface in one enclosure for decentralized motion control. Mounting the drive electronics on the motor frame reduces panel heat and wiring requirements in automated assembly cells, pick-and-place axes, and compact packaging stations where cabinet space is limited. The integrated design also shortens the cable routes between the motor, drive, and communication network.

The drive operates from a 750 VDC bus, allowing it to connect directly to a shared DC link without an intermediate converter. Power, brake, and Ethernet conductors are combined in a single hybrid connector, reducing the number of cables routed along the machine frame. Heat is removed through natural convection, so the mounting arrangement must provide unobstructed airflow around the housing. Shaft position is measured by a Hiperface optical encoder that produces 128 signal periods per revolution for fine position interpolation. The motor has size 076, length code C, winding code 35, and a shaft with a keyway. The unit is design version 1 and provides a torque and speed range suited to typical packaging duties.

The built-in Multi-Ethernet port allows the axis to communicate over PROFINET, EtherNet/IP, Sercos III, or EtherCAT through the appropriate network configuration. A multi-turn absolute measuring system retains absolute position information, eliminating the need for homing after an emergency stop. The Safe Motion package supports monitored stopping and safely limited speed when the drive is paired with a certified controller. The unit is supplied without a holding brake, so an external holding method may be required for loads that must remain stationary when power is removed. A factory-installed shaft seal protects the bearings from dust and splashing liquids. The integrated feedback system also removes the need for a secondary position encoder in compatible applications.
