Product Description:

The KSM02.1B-061C-35N-M1-HP0-ET-S3-D7-NN-FW is a drive unit produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. Designed for installation directly on moving axes, it combines a permanent-magnet motor, a feedback system, and power electronics in one housing, which reduces cabinet wiring in decentralized automation lines such as packaging or assembly cells. Its product type code indicates that the servo inverter is mounted directly on the motor instead of in a separate cabinet. Because the drive electronics are mounted at the axis, the machine can keep power conversion close to the point of motion. That layout is useful on gantries and transfer modules where long motor cable runs are undesirable.

Its single-cable lead uses a Hybrid Connector that carries DC power, control voltage, and network signals through the same sheath. The inverter draws from a DC 750 V bus shared with neighboring axes. Heat is dissipated by natural convection, so the finned aluminum housing releases energy without fans. An optical multi-turn absolute encoder reports position over Hiperface and provides 128 signal periods per revolution for smooth low-speed motion. The unit uses motor size 061 with C length and winding code 35, and it is supplied as a series 2 product with a basic performance level, a standard design option, and version 1 design. A shaft seal protects the bearings from dust and splash.

Fieldbus integration is handled by Multi-Ethernet, allowing the axis to accept EtherNet/IP, EtherCAT, or PROFINET commands through the same interface. This communication flexibility lets the same axis platform fit different control architectures in automated equipment. The drive includes Safe Motion functions that supervise speed and position internally when the external safety circuit enables operation. Mechanical energy reaches the load through a shaft with a keyway that mates with standard couplings. Because the motor is supplied without a holding brake, vertical or suspended axes must rely on an external brake or drive torque to hold position during power-off states.
