Product Description:

The KSM02.1B-061C-61N-S1-HP0-ET-L3-D7-NN-FW is produced by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. This motor-integrated servo drive combines a permanent-magnet motor, encoder, power electronics, and network interface in one housing, reducing cabinet wiring. In automated assembly lines, packaging stations, and material-handling axes, the unit delivers decentralized torque and position control while drawing its DC link energy from a common supply. By embedding the drive directly on the machine frame, the installation can use shorter cable runs and simpler thermal management.

The drive is powered from a DC 750 V bus and couples to the energy chain through a single Hybrid Connector, which carries power, communication, and safety circuits in one molded shell. Heat is expelled by natural convection, eliminating the need for fans. Motion feedback is generated by an optical encoder that follows the Hiperface protocol and resolves rotor position into 128 signal periods per mechanical turn, supporting smooth velocity loops. Parameterization and diagnostics pass over the master fieldbus via Multi-Ethernet, allowing the same unit to join PROFINET, EtherNet/IP, or EtherCAT topologies. The motor section follows length code C, winding code 61, and size 061, aligning its electromagnetic design with medium-torque tasks.

Functional safety is delivered through Safe Torque Off (STO), which disables the power transistors so residual motion cannot occur. The feedback device is a single-turn encoder, so the controller reads absolute position within one revolution. Mechanical output is provided by a shaft with a keyway that mates with standard couplings, and a shaft seal is installed to guard against fluid ingress. Because the unit is supplied without a holding brake, external clamps or drive torque must maintain position when powered down. The unit uses the standard design option and is design version 1 with Basic performance level and Series 2.
