KSM02.1B-061C-61N-M1-HG0-ET-NN-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HG0-ET-NN-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines a permanent-magnet synchronous motor with an embedded drive controller, reducing cabinet space and wiring requirements in automation cells. The unit belongs to Series 2 and Design Version 1. It has a size of 061, a length code of C, and a winding code of 61. The drive has the Basic performance level and is intended for point-to-point motion tasks that require accurate positioning and moderate dynamic response.

The device receives power from a DC 750 V bus and dissipates heat through natural convection, eliminating the need for forced cooling equipment. Power, signal, and safety conductors terminate in a single hybrid connector, reducing the number of separate connections required on multi-axis machines. Rotor position is captured through a Hiperface interface connected to an optical encoder with 128 signal periods. This feedback resolution supports precise commutation and smooth motion at low speeds. The encoder signals feed directly into the embedded control electronics, so external feedback cabling is not required between the motor and controller.

For networked motion, the embedded controller provides Multi-Ethernet output coupling that supports Sercos, EtherCAT, PROFINET, and Ethernet/IP without additional option cards. Absolute rotor position is retained by a multi-turn absolute measuring system, eliminating the need for a homing routine after a power interruption. Mechanical power is transmitted through a plain shaft with a shaft seal, which works with standard backlash-free couplings while limiting the ingress of dust or coolant. The shaft is factory lubricated for normal operation with compatible couplings. The drive is built without a holding brake or integrated safety technology, so load holding and required safety functions must be provided by external devices.
