Product Description:

Bosch Rexroth Indramat designed the KSM01.2B-041C-42N-M1-HG2-SE-NN-D7-NN-FW for its KSM Motor Integrated Servo Drives series. As a motor-integrated servo drive, the unit places the inverter electronics directly on the motor body, creating a decentralized axis that simplifies cabling in flexible assembly lines and palletizers. It receives high-voltage DC power from a common bus and delivers closed-loop speed and position control for medium-torque tasks in packaging, handling, and light machining cells. This arrangement keeps the power electronics close to the motor and supports compact axis layouts where cabinet space is limited.

The drive accepts a bus voltage of DC 750 V, with rectified power supplied elsewhere in the system through a hybrid connector that carries both power and SERCOS fiber pairs. Position feedback comes from an optical Hiperface encoder that resolves 128 signal periods per mechanical revolution. Because it is a multi-turn absolute device, the controller retains shaft-angle information after power loss. The encoder assembly sits in a size-041 stator with length C, giving the unit a compact footprint for machines with limited space. An electrically released brake rated at DC 24 V holds the load during an emergency stop, and the aluminum housing sheds heat by natural convection without external fans.

Commutation uses winding code 42, and cyclic setpoints are exchanged over SERCOS 2 (RS422) for coordination with the line controller. The motor has a plain shaft with a shaft seal that helps block oil mist, while the combined power-and-signal plug keeps the connection layout compact. The unit is design version 2 with a standard mechanical option set and basic performance level. It is supplied without integrated safety technology, and the housing follows standard dimensions for this product line.
