Product Description:

The KSM02.1B-076C-35N-S1-HG2-ET-S3-D7-NN-FW is a decentralized axis unit manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. This device unites a brushless servo motor, a power inverter, and control electronics inside one housing, letting the drive be mounted directly on moving or stationary machine parts. In industrial automation, it provides closed-loop position, speed, and torque control without needing a separate cabinet drive, which reduces installation space and shortens the distance between the motor and power electronics. That layout also supports compact axis assemblies in transfer systems, pick-and-place modules, and conveyor sections where remote cabinet mounting is less practical.

It operates from a DC 750 V intermediate circuit and routes that supply, signal, and protective earth through a single Hybrid Connector, minimizing field wiring and reducing the number of separate cable entries at the axis. Heat generated by the inverter is dissipated by natural convection, so no fans or liquid lines are necessary. Position feedback is produced by an Hiperface encoder that uses optical sensing to deliver 128 signal periods per revolution, with single-turn absolute data available at startup. Real-time setpoints reach the controller through Multi-Ethernet, allowing common industrial Ethernet protocols to be used on the same platform. The unit uses the standard design option, design version 1, motor length C, winding code 35, and series 2 with a basic performance level.

The electrically released holding brake engages when power is removed and is energized at DC 24 V, which helps hold the axis during stopping or standby conditions. Integrated functional safety is provided through Safe Motion (without SBC), allowing safe stop and speed monitoring functions inside the unit. A shaft seal protects the internal bearings, and the plain output shaft simplifies coupling to gearboxes or timing pulleys. The coded motor frame of 076 supports compact installation where small packaging and handling axes need a short overall envelope. This arrangement suits applications that need an integrated motor-drive package with onboard braking and feedback in a limited mounting space while maintaining closed-loop motion control at the axis.
