KSM02.1B-061C-61N-M1-HP0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat and supplied within the KSM Motor Integrated Servo Drives series. By combining drive electronics with a permanent-magnet synchronous motor in one housing, it reduces panel wiring and shortens feedback loops in distributed automation cells. The unit is intended for precise positioning and speed control on packaging axes, small pick-and-place gantries, or high-throughput conveyor sections.

The drive connects to the machine harness through a single hybrid connector that routes DC power, signals, and network lines together, simplifying installation. Heat produced by the inverter stage is removed through natural convection, so no fans or liquid circuits are required in IP-rated enclosures. Internal power electronics accept a bus voltage of DC 750 V, allowing shared energy storage with other servo modules on the line. Rotor position is reported to the control loop over a Hiperface interface, which supports electronic nameplate data and automatically aligns resolver counts with the drive. The assembly is delivered without a holding brake, which means an external mechanical clamp or closed-loop torque is needed when the shaft must remain locked while the machine is idle.

Fine positioning accuracy comes from an optical encoder that yields 128 signal periods per revolution and stores absolute angle data across multiple turns; the resulting feedback has a multi-turn absolute configuration. Real-time motion commands are exchanged through a Multi-Ethernet master stack, so the device can join EtherNet/IP, PROFINET IO, or EtherCAT topologies without extra option cards. Torque is transferred through a shaft with a keyway, and the mechanical frame has a size of 061 with length code C. The standard shaft seal helps protect the motor interior from contaminants around the output interface. Winding code 61 identifies the electrical arrangement used for the stator, while the Basic performance level indicates the drive's functional configuration.
