KSM02.1B-061C-61N-M1-HG2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HG2-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a motor, power electronics, and control logic in one housing, the device supports decentralized motion axes in packaging machines, material-handling gantries, and other automated cells. It is a Series 2 unit with a basic performance level. The motor uses a plain shaft with an internal shaft seal that helps prevent lubricant leakage and contaminant entry.

The drive operates from a bus supply of DC 750 V, allowing it to connect directly to a common DC link that supplies multiple axes. Power, control, and safety signals are carried through a single hybrid connector, which reduces cabinet wiring and simplifies installation. Heat is removed by natural convection, so the unit does not require fans or liquid cooling circuits. Position data is captured through a Hiperface optical encoder that provides 128 signal periods per revolution, supporting precise velocity and position loops. The encoder has multi-turn absolute feedback, allowing it to retain position information after a loss of power. The motor has a frame size of 061, a length code of C, and a winding code of 61 for light-to-medium-duty motion axes.

An electrically released brake holds the rotor while the axis is stationary and uses DC 24 V to disengage during motion. Control networking is handled by Multi-Ethernet, allowing the unit to communicate over EtherNet/IP, PROFINET, or EtherCAT without a separate communication module. Integrated Safe Motion without SBC provides drive-based safety functions, including safe torque off and monitored motion capabilities. The drive uses the standard mechanical option and design version 1. Its decentralized arrangement places motion control close to the driven axis, reducing long motor cable runs between the control cabinet and the machine.
