Product Description:
The KSM02.1B-041C-42N-M3-HP2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and delivered as part of the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor with decentralized drive electronics, it provides torque, position, and networked control at the machine axis without a separate cabinet inverter. This arrangement simplifies installation for conveying, packaging, and pick-and-place cells.
The drive accepts a DC bus of DC 750 V, supplying the integrated inverter with the high intermediate-circuit voltage used across Rexroth distributed drive platforms. Power, feedback, and fieldbus conductors are consolidated in a Hybrid Connector, so a single cable carries motor power, brake lines, and Ethernet. Thermal losses are dissipated through natural convection, and no fan is fitted. Command and diagnostic traffic uses the built-in Multi-Ethernet interface, allowing protocol selection for Profinet, EtherNet/IP, Sercos over Ethernet, or EtherCAT. Axis holding torque is supplied by an electrically released spring-applied brake that engages automatically when DC power is removed. The unit is series 2 with motor size 041 and length C. It uses the standard design option, has a basic performance level, and is design version 1.
The brake coil is energized with DC 24 V, matching common control supplies and keeping the brake independent from the main DC link. Position feedback comes from a Hiperface interface that works with a capacitive sensor head delivering 16 signal periods per mechanical revolution, while multi-turn absolute counting preserves position across power cycles. Winding code 42 is used with this length-C stator for balanced current density. Motion is transmitted through a shaft with a keyway, and a shaft seal is fitted to guard the front bearing against contaminants.
