KSM02.1B-061C-61N-S1-HG2-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-S1-HG2-ET-L3-D7-NN-FW is manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines a size 061 stator with a C-length housing and winding code 61 to provide axis-specific motion without a separate cabinet-mounted drive. This second-generation unit is version 1, uses the Standard option, and offers a Basic performance level for general automation tasks. Because the power electronics, encoder, and network interface are located with the motor, the design shortens cable routes and reduces the amount of wiring required in multi-axis machines. The integrated arrangement is suitable for distributed motion systems used in packaging, material handling, and production equipment.

The drive operates from a DC 750 V link, allowing it to share a common supply with other servo modules on the bus. Heat generated by the inverter is removed through natural convection, so no fans or liquid manifolds are required. Command and diagnostic traffic moves over the manufacturer's Multi-Ethernet platform, providing access to EtherNet/IP, PROFINET, or EtherCAT through a common communication interface. Rotor position is measured by a Hiperface feedback system that uses an optical sensor array with a resolution of 128 signal periods. This feedback arrangement supports smooth velocity control and precise positioning in pick-and-place, packaging, and woodworking axes. The single-turn encoder provides absolute position information within one mechanical revolution when power is restored.

An electrically released brake rated at DC 24 V secures vertical loads and other stationary loads whenever control power is removed. Integrated Safe Torque Off (STO) permits the drive to interrupt torque generation without relying on external power contactors for this function. Mechanical output is delivered through a plain shaft, which accommodates clamping couplings and other keyless connections. A shaft seal limits the entry of dust and moisture around the rotating interface during operation. Power, signal, and network lines are combined in a single hybrid connector, reducing cable bulk and simplifying machine-side routing. The connector consolidates the required electrical paths while maintaining separate functions for motor power, control communication, and feedback signals.
