Product Description:

The Bosch Rexroth Indramat KSM02.1B-041C-42N-M1-HG2-ET-S3-D7-TO-FW is a motor-integrated servo drive from the KSM Motor Integrated Servo Drives series. By combining the servo controller, power stage, and synchronous motor in one enclosure, it mounts directly on machine frames and reduces cabinet wiring. The unit is used in decentralized automation lines to provide closed-loop torque, speed, and position control for packaging, handling, and assembly axes. This layout also shortens cable runs between the drive and the motor section.

Power is delivered through a Hybrid Connector, so DC bus, control, and fieldbus conductors share one plug, simplifying installation. Internally, the drive operates from a nominal DC 750 V supply and dissipates losses by natural convection, eliminating fans. Position feedback is handled through Hiperface communication with an optical transducer that delivers 128 signal periods per revolution, and the multi-turn absolute format preserves position after power-off events. An electrically released holding brake secures the shaft when the enable signal drops. The motor uses size 041 with length C, and winding code 42 indicates the electromagnetic loading used in this Basic performance unit, producing the continuous torque needed by small pick-and-place gantries.

This drive is design version 1 and is in Series 2. The smooth shaft uses an internal shaft seal to help prevent lubricant escape during washdown cycles. Application controllers exchange cyclic data over the Multi-Ethernet interface. Integrated safety technology provides Safe Motion (without SBC), enabling controlled stops and monitored standstill without external relays. The brake coil accepts DC 24 V, and the controller coordinates brake release through Safe Torque Off lines during emergency power removal.
