Product Description:

The KSM02.1B-041C-42N-M3-HP2-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By combining drive electronics, certified safety circuitry, and a brushless servo motor in one IP-rated housing, the unit mounts directly on the machine frame. It regulates torque, speed, and position close to the mechanical load, which helps reduce cable runs between the cabinet and the axis. This layout supports compact machine designs used in packaging, material handling, and small-parts assembly cells.

Power is supplied through a Hybrid Connector that routes the DC bus, control, and network lines through a single plug, helping keep wiring compact. The drive accepts a nominal bus voltage of DC 750 V, which matches IndraDrive modular power supplies. Thermal management relies on natural convection, so airflow around the housing must remain unobstructed during operation. The unit uses Multi-Ethernet communication for PROFINET, EtherNet/IP, and related industrial protocols without additional hardware. The holding brake is electrically released, so it can secure a gravity-loaded axis when power is removed. The motor has size 041, length C, and winding code 42, while the internal design is version 1 in series 2 with a Basic performance level.

Position feedback is delivered through the Hiperface interface by a capacitive sensor with 16 signal periods, and it transmits multi-turn absolute data to the controller. When Safe Torque Off (STO) is asserted, the drive power stage is de-energized while diagnostic channels remain active. The brake coil operates on DC 24 V and engages automatically when bus power is absent. Output torque reaches the load through a shaft with a keyway, and a shaft seal helps limit ingress during washdown or cutting-fluid exposure. These features support applications that need integrated motion control, retained feedback status, and protected power transmission at the machine axis.
