KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M3-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a synchronous motor with an onboard drive controller, it provides decentralized axis control for conveyors, pick-and-place gantries, and other motion tasks in industrial automation systems. Integrating the motor and controller reduces the amount of wiring between the machine and the control cabinet. The device belongs to Series 2 and has the basic performance level, enabling distributed motion without expanding the control cabinet.

The unit operates from a 750 V DC bus, allowing it to connect directly to a compatible machine power supply. A hybrid connector provides a single-cable interface for power, signals, and communication, simplifying wiring when several axes are connected in a daisy chain. Heat is removed exclusively through natural convection, so adequate clearance must be maintained around the housing without the need for fan maintenance. Real-time control is provided through Multi-Ethernet communication, which supports the selection of compatible industrial Ethernet protocols through the control system. Integrated Safe Torque Off (STO) removes torque-producing energy from the motor when the safety function is activated. The unit uses the standard design option and Design Version 1, maintaining a consistent mechanical envelope within the KSM series.

The position feedback system uses a Hiperface interface with a capacitive scanning element. It produces 16 signal periods per mechanical revolution and reports multi-turn absolute position data, allowing the controller to retain axis position information across operating cycles. The drive section is matched to motor size 061 with frame length C and uses winding code 61 for the required torque characteristics. A plain shaft with an integral shaft seal transmits mechanical output while helping protect the bearing area from contaminants. The assembly is supplied without a holding brake, so stationary loads must be supported by external mechanics or drive-generated torque when required.
