Product Description:

The KSM02.1B-041C-42N-S1-HP2-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, feedback system, and drive electronics in one housing, the unit streamlines cabinet layouts and shortens cable runs in distributed automation zones. It handles positioning and velocity control directly on the machine while receiving commands through the series-2 Multi-Ethernet interface built into the drive. Because the inverter is integrated into the motor body, the axis can be installed as a compact decentralized drive package in automated handling, packaging, and transfer systems.

For power, the drive accepts a nominal bus of DC 750 V, which matches 750 V DC-link systems and supports the internal winding code 42 stator. Heat produced by the inverter stage is removed by natural convection, so no fans are required and the installation only needs adequate ambient airflow around the housing. All power, signal, and brake leads terminate in a single hybrid connector, which reduces ingress points and keeps the cable interface concentrated at one connection point. Functional safety is handled onboard with Safe Torque Off, allowing torque-producing energy to be removed without disconnecting the supply. Motion feedback is transmitted through the Hiperface interface, which carries position data and electronic motor information to the controller.

The optical single-turn encoder provides 128 signal periods, giving sufficient angular resolution for standard PLC-based motion loops. When power is removed, the electrically released brake engages at DC 24 V to hold the axis in place until drive control is restored. Mechanical power is transmitted through a shaft with keyway, which allows positive torque transfer to couplings or gearbox inputs that use a keyed connection. A factory-installed shaft seal helps keep coolant or dust away from the bearing area. Frame size 041 with length code C gives the motor a compact envelope and an inertia class suited to moderate load profiles.
