KSM02.1B-041C-42N-S3-HG2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-041C-42N-S3-HG2-ET-NN-D7-NN-FW is manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. This motor-integrated servo drive places power electronics, feedback components, and a brushless servo motor in one housing, allowing decentralized axes to be mounted directly on machinery without a separate cabinet inverter. It is intended for position-controlled motion tasks in packaging, material handling, or small assembly cells where compact installation and reduced wiring are priorities.

The drive connects to the DC bus at 750 VDC, giving the internal converter sufficient headroom for fast torque transients. Power, feedback, and I/O connections share a single hybrid connector, simplifying installation and minimizing cable loops between moving modules. Heat is removed through natural convection, so no fans or liquid lines are required. Position feedback is transmitted through a Hiperface interface. Its capacitive single-turn encoder produces 16 signal periods per mechanical revolution, allowing high-resolution interpolation in the controller. The motor has length code C and winding code 42. Its plain shaft includes an integral shaft seal that helps prevent contaminants from reaching the internal components.

An electrically released holding brake rated at 24 VDC secures the load when the DC link is disabled, eliminating the need for external clamps on vertical axes. Command and diagnostic data travel over the Multi-Ethernet master interface, enabling the unit to connect to EtherCAT, PROFINET, or EtherNet/IP networks without changes to its communication hardware. The physical frame size is indicated by code 041, which provides a compact profile for installation near the driven mechanism. The drive has a basic performance level and belongs to design version 1 and series 2. It does not include integrated safety technology, so required safety functions must be provided elsewhere in the machine control system.
