KSM02.1B-041C-42N-M1-HG0-ET-SD-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-041C-42N-M1-HG0-ET-SD-D7-ES-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. It combines drive electronics and a synchronous motor in one housing to provide decentralized axis control for conveying, packaging, and assembly systems. This arrangement places motion control close to the driven axis, reducing the amount of power and signal wiring routed to the main cabinet. The unit can regulate position, velocity, and torque for machinery that requires compact motion control across multiple coordinated axes.

The drive receives power from a 750 V DC supply, allowing it to operate with other compatible devices on a common DC bus. Heat is dissipated through natural convection, so the installation does not require forced-air components around the motor housing. Power, safety, and feedback lines pass through a single hybrid connector, reducing the number of separate cable connections between the drive and the cabinet. Command data are exchanged through an external Multi-Ethernet interface that supports several real-time industrial communication protocols. The unit has design version 1, belongs to internal series 2, and provides the Basic performance level. These characteristics support distributed control without requiring a separate drive module for each motor inside the main enclosure.

Position feedback is supplied by a Hiperface encoder with 128 signal periods from its optical tracks, providing the drive with detailed rotor-position data. Its multi-turn absolute capability retains position information across multiple shaft revolutions, reducing the need to establish the axis position again after a power cycle. The integrated Safe Motion system with SBC supports monitored motion and safe brake control functions within the drive architecture. The motor has a size of 041, a motor length of C, and winding code 42 for its electrical configuration. Its plain shaft has no keyway, allowing it to work with low-backlash clamping couplings during bidirectional motion. A shaft seal provides moderate protection against contaminant entry around the output end. The drive is supplied without a holding brake, so an external mechanism or drive-applied torque must secure static loads when required.
