KSM02.1B-061C-61N-M1-HG2-ET-NN-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HG2-ET-NN-D7-TO-FW is a motor-integrated servo drive from Bosch Rexroth Indramat's KSM Motor Integrated Servo Drives series. By combining a synchronous motor, power stage, and fieldbus interface in one housing, the unit provides decentralized axis control for conveyors, pick-and-place modules, and packaging stations. This arrangement reduces cabinet wiring because the drive electronics mount directly on the motor, leaving only a DC bus and communication line to be routed along the machine frame.

Its single-cable power and signal interface uses a hybrid connector, which carries DC bus, safety shunt, and feedback lines in one molded plug. Heat produced by the electronics is removed through natural convection, so no fans are required and the enclosure remains sealed. Position feedback is handled by a Hiperface encoder. The optical scanning head reads the code disk at 128 signal periods per revolution and provides multi-turn absolute position data to the controller. The internal DC link accepts up to DC 750 V, allowing the axis to receive power from a common regenerative bus in machines with multiple axes. Network traffic and parameter data travel over the built-in Multi-Ethernet interface, which supports SERCOS III, EtherNet/IP, EtherCAT, and PROFINET without additional option cards.

The servo section uses an electrically released holding brake energized by DC 24 V to secure vertical loads during standby. Mechanical output is delivered through a plain shaft with a shaft seal, which helps protect the motor from dust and spray. The motor has size 061, length code C, and winding code 61, providing torque suited to its intended drive configuration. The drive has a Basic performance level for general-purpose motion applications. It is design version 1 and Series 2, indicating its position within the product family.
