KSM02.1B-071C-35N-S1-HG0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-35N-S1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By embedding inverter electronics in the motor housing, the unit provides decentralized motion control for assembly stations, packaging equipment, and material-handling axes. This arrangement removes the need for a separate drive enclosure and reduces the length and number of cable runs on the machine frame. The unit is Series 2, uses the Standard design option, and has design version 1. Its Basic performance level supports general positioning and speed-regulated tasks in industrial automation.

The drive receives power through a 750 V DC link connected to a common IndraDrive bus. Heat leaves the housing through natural convection, so the unit does not require cooling fans. Command and diagnostic data travel through Multi-Ethernet, which supports several industrial Ethernet variants. An optical encoder supplies 128 signal periods per revolution through the Hiperface interface. Its single-turn measurement provides absolute position information within one mechanical revolution. Functional safety is provided by Safe Motion without SBC, which supervises speed and standstill within the drive.

Power, feedback, and auxiliary conductors share a Hybrid Connector, reducing the number of separate connection points required on the housing. Drive torque is transmitted through a plain shaft with a shaft seal, which helps prevent lubricant leakage and contaminant entry around the shaft opening. The motor has a frame size of 071 and a frame length of C, providing the mechanical envelope associated with this model. Winding code 35 indicates the electrical configuration used with the integrated power stage. The unit does not include a holding brake, so static load retention must be supplied by drive torque or an external holding mechanism when the axis is stationary.
