KSM02.1B-041C-42N-M1-HP0-ET-SD-D7-NN-FW

The KSM02.1B-041C-42N-M1-HP0-ET-SD-D7-NN-FW from Bosch Rexroth Indramat is a compact KSM Motor Integrated Servo Drives solution that integrates motor and drive electronics into a single enclosure. This servo drive features a Product Type classified as a motor-integrated servo drive, with a Motor Size of 041 and a Winding Code of 42 for precise torque control. With a nominal Supply Voltage of DC 750 V, the unit delivers reliable power in applications requiring up to 470 W of rated power. The robust design achieves an IP65 rating (including Shaft Seal technology) while maintaining a total system weight of approximately 5.6 kg and a compact footprint of 252 mm length, 82 mm diameter, and 194 mm height.

The technical capabilities of this servo drive are characterized by its Encoder Interface implementing Hiperface protocol on a Hybrid Connector for combined power and feedback connections. The Encoder Technology uses an optical sensor with Encoder Resolution of 128 signal periods and a Encoder Turn Type multi-turn absolute configuration to guarantee accurate position tracking without homing. Its Safety Technology is provided by the Safe Motion option (with SBC) allowing for safe brake controls and monitored stop functions. The drive’s DC bus features a capacitance of 0.12 mF, a short-circuit current rating of 42,000 A, and a maximum bypass current of 25 A, while switching frequencies can be configured at 4 kHz or 8 kHz for optimized performance. Conforming to Performance Level Basic and certified to CSA and UL 508, this unit is designed for rigorous industrial standards.

Operational features deliver efficient thermal management and reliable continuous operation. The drive employs Cooling Type based on natural convection, enabling passive dissipation of 70 W power dissipation at continuous current in ambient temperatures from 0 °C to 40 °C and installation altitudes up to 1,000 m. The integrated Master Communication Protocol uses Multi-Ethernet (including SERCOS 2) to facilitate high-speed synchronization and deterministic control across distributed automation networks. An optional Holding Brake can be specified separately to add standby torque retention, while the pre-installed Shaft Type shaft with keyway and sealing ring prevents contamination ingress and ensures secure mechanical coupling. Firmware for the system is supplied separately, allowing users to update and customize feature sets according to their application needs.

Integration and application of the KSM02.1B unit is straightforward due to its modular Design Version 1 construction and standardized interfaces. The compact Series 2 drive can be mounted alongside other KSM units in multi-axis configurations, benefiting from the unified power and feedback Connection Type hybrid connector. Whether deployed in packaging machinery, robotics, or semiconductor wafer handling, this motor-integrated servo drive provides synchronized motion control, precise positioning, and simplified wiring. Backed by a one-year warranty from Wake Industrial and global shipping support, the drive is ready for rapid integration into demanding automation environments.
