Product Description:

The KSM02.1B-041C-42N-M1-HP0-SE-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By embedding the power electronics inside the motor housing, it supports decentralized axis control on conveyor sections, pick-and-place modules, and compact machining cells where cabinet space is limited. This layout shortens the paths for motor power and feedback signals, which helps keep the installation compact and reduces the amount of separate drive hardware mounted elsewhere on the machine.

The drive runs from a DC 750 V intermediate bus that can be shared among multiple axes in a common system. Heat is removed by natural convection, so the unit does not require fan assemblies or liquid-cooling circuits around the motor body. All motor power, logic supply, and fieldbus conductors enter through one Hybrid Connector, which keeps the cable interface concentrated at a single entry point. Position feedback is provided by a Hiperface encoder that delivers 128 signal periods per revolution for interpolation, and the unit uses the standard design option with Design Version 1, a basic performance level, and motor length C. Because the servo drive is supplied without a holding brake, load retention during power-off conditions must be provided by external machine hardware.

Real-time command exchange is handled through SERCOS 2 (RS-422), giving the controller deterministic communication for coordinated motion. The optical encoder also provides multi-turn absolute position data, so the axis can recover stored position information after a restart without requiring a reference move in every application. Drive torque is transmitted through a keyed shaft built for frame size 041, and a shaft seal helps protect the bearing area from coolant spray. Electromagnetic behavior is set by winding code 42, which establishes the motor’s current and speed constants within the Series 2 platform.
