KSM02.1B-061C-35N-M1-HG2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HG2-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines power electronics, control electronics, and a synchronous motor in one housing. This integrated arrangement decentralizes axis control and reduces the amount of wiring required between the motor and the control cabinet. The unit is suitable for automated assembly lines, material-handling systems, and compact production cells where installation space is limited.

Electrical power reaches the servo section through a hybrid connector that carries the DC bus, logic, and fieldbus signals in one sealed plug. This combined connection simplifies daisy-chain installation and reduces the number of separate cables routed along the machine. The drive section operates from a 750 V DC link, allowing it to receive power from a shared intermediate circuit in a modular drive system. Heat is removed by natural convection, eliminating the need for fans or forced-air equipment. Rotor position is tracked through a Hiperface feedback interface, while the optical encoder provides 128 signal periods per revolution for accurate commutation and smooth torque control. An electrically released brake clamps the shaft when its 24 V supply is absent, helping secure the connected load when power is removed.

Machine-level communication is handled through Multi-Ethernet, allowing the unit to operate on EtherNet/IP, PROFINET, or EtherCAT networks when configured for the selected protocol. This network support enables cyclic command exchange, operating status reporting, and coordination with the machine controller. Functional safety is provided by Safe Motion without SBC, which supports controlled stopping and limited-speed monitoring without a separate safety bus coupler. The motor uses a plain shaft for direct connection to a compatible coupling, and a shaft seal helps limit contaminant entry in areas exposed to splashing water. Its motor size is 061, its length code is C, and its winding code is 35. These codes identify the motor's physical format and electrical arrangement without requiring separate motor and drive assemblies at the axis.
