KSM02.1B-061C-35N-M1-HP0-ET-NN-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HP0-ET-NN-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a servo motor and drive electronics in one enclosure, the unit streamlines wiring and reduces cabinet space requirements in distributed automation cells. It accepts DC bus power from central supplies and provides position, speed, and torque control directly at the axis. This arrangement is suitable for packaging machines, handling gantries, and other multi-axis assemblies that benefit from a decentralized drive architecture.

Wiring to the drive is consolidated in a hybrid connector that carries power, control signals, and feedback through a single plug. Heat produced by the electronics is removed through natural convection, so no fans are required. The power stage operates from a 750 V DC intermediate circuit that is compatible with common drive supply modules. Rotor position data are transmitted through a Hiperface interface, and the optical sensor provides 128 signal periods per mechanical revolution. This resolution gives the controller fine interpolation for smooth velocity regulation without requiring separate feedback cabling.

The encoder stores absolute position over multiple turns through its multi-turn absolute capability, eliminating the need to perform a homing cycle after power loss. With a frame size of 061 and motor length code C, the unit fits compact machines that require moderate torque. Its Basic performance level supports standard positioning tasks. The device does not include a holding brake, so an external holding method is required for vertical loads when power is removed. Mechanical power is transmitted through a shaft with a keyway, and a shaft seal limits contaminant ingress at the coupling. Multi-Ethernet communication supports integration with compatible industrial networks, while winding code 35 identifies the motor winding paired with the drive current characteristics.
