Product Description:
The KSM02.1B-041C-42N-M3-HP2-ET-NN-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining inverter electronics and the mechanical actuator in one housing, it removes the need for a central cabinet-mounted amplifier and shortens feedback cabling on distributed automation lines. The design supports decentralized axes in packaging, material handling, and light machining cells where accurate speed and position control must be delivered at the point of motion without extra enclosure space.
This unit accepts a bus voltage of DC 750 V, and its inverter stage feeds three-phase stator windings with winding code 42. Connection is made through a single hybrid connector that carries power, safety earth, and fieldbus leads in one molded shell. Heat from the power semiconductors is dissipated by natural convection, so the housing should be mounted where ambient air can circulate freely. Rotor feedback is transmitted through a Hiperface interface, and position is measured at 16 signal periods per mechanical turn. The motor has size 041 and length code C, uses a keyed shaft for direct coupling, and is design version 1 with a basic performance level and series 2.
The sensing system uses a capacitive multi-turn absolute encoder, so position data is retained after power is removed without requiring batteries. Axis holding is provided by an electrically released brake that engages when the control supply is removed, and the brake operates at DC 24 V to secure vertical or inertial loads during downtime. Real-time commands and diagnostic data move over Multi-Ethernet, allowing integration with EtherNet/IP, PROFINET, or EtherCAT networks. A factory-installed shaft seal helps block lubricant migration, and the keyed shaft supports positive torque transmission in general-purpose machinery.
