Product Description:

The KSM02.1B-061C-35N-M1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor with an embedded drive controller in one housing, the unit reduces external wiring and helps simplify cabinet layouts in distributed automation cells. It provides decentralized axis control on packaging, material-handling, and assembly lines where compact drive hardware supports precise motion without requiring a separate amplifier enclosure. This arrangement places the power electronics directly at the machine axis, which helps shorten motor leads and keeps the drive package close to the moving mechanism.

The drive operates from a DC 750 V bus, allowing direct connection to regenerative supply modules used in modular machine platforms. Power, signal, and safety lines enter through a single Hybrid Connector, which reduces cable count between the axis and the supply chain. Heat from the inverter stage is removed by natural convection, so the unit does not require external fans. Command and diagnostic data are exchanged over Multi-Ethernet, allowing the drive to communicate with higher-level automation systems through common industrial Ethernet protocols. Servo feedback is handled through a Hiperface interface, supporting closed-loop position control and reliable data exchange between the motor and the integrated electronics.

Position accuracy is supported by an optical encoder that provides 128 signal periods per motor revolution and offers Multi-turn absolute tracking, so the axis retains position information after power is removed. This feedback arrangement also supports stable commutation and accurate speed regulation during repeated indexing and positioning moves. The motor uses 061 stator laminations with length code C and winding code 35, matching the compact frame to basic-performance motion tasks. A shaft seal is installed, and the output uses a plain shaft for direct coupling to gearboxes or pulleys. Safe Motion with SBC is integrated for safe stop functions, and the unit is supplied without a holding brake to keep overall length and inertia low.
