Product Description:

The KSM02.1B-061C-61N-M3-HG2-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. It combines drive electronics, the power stage, and the servo motor in a single unit to shorten cable runs and reduce control cabinet dimensions. Within automated packaging lines or compact assembly cells, it supplies decentralized torque, speed, and position control to individual axes. The integrated layout also reduces the amount of separate wiring that must be routed between the cabinet and the machine axis.

Mechanical, electrical, and feedback elements are consolidated through a Hybrid Connector, so power, signal, and network lines reach the unit through one plug. This arrangement reduces the number of separate cable entry points at the motor location. Heat leaves the housing through natural convection, eliminating fans and supporting use in IP-sealed machines. Rotor position is monitored by a capacitive encoder that transmits via Hiperface and offers 16 signal periods per mechanical revolution, while its multiturn absolute feature stores position across power cycles. A brake that is electrically released secures the axis when power is off, and its coil is energized with DC 24 V. Size code 061, length C, and winding 61 indicate the motor's electromagnetic package, while design version 1 identifies this build.

Communication runs over Multi-Ethernet, allowing Sercos, EtherCAT, or PROFINET selection without changing hardware, while the drive draws energy from a DC 750 V shared bus in distributed machines. Motion can be inhibited by Safe Torque Off (STO), which provides a basic functional safety stop function. The shared DC bus supports decentralized machine layouts in which several axes are supplied from the same power backbone. A plain shaft end simplifies coupling, and a shaft seal helps prevent lubricant escape in vertical orientations. That shaft style is commonly paired with clamping couplings or similar hubs.
