Product Description:
The KSM02.1B-041C-42N-M1-HG0-ET-NN-D7-N-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining drive electronics and a synchronous motor within one housing, the unit streamlines cabinet wiring and shortens feedback loops in compact machines and modular handling stations. In an automation line, it delivers position, speed, and torque control directly at the axis, allowing decentralized servo nodes to operate without separate drive modules. This integrated arrangement also reduces the length of power and feedback connections between the motor and drive electronics.
The drive accepts a supply of DC 750 V from a shared bus and passes power, control, and 24 V auxiliary lines through a single hybrid connector. Motor winding code 42 pairs with motor length C to provide continuous torque and current limits for midrange duties. Heat produced by the electronics is removed through natural convection, so no forced-air fans are required in the mounting area. The unit is Version 1, has a basic performance level, and belongs to Series 2. A factory-installed shaft seal helps prevent dust and splashing fluids from entering the housing. The unit is supplied without a holding brake, so stationary loads must be secured by drive torque or an external mechanical device.
Rotor position is measured by an optical encoder that communicates over Hiperface and provides 128 signal periods per mechanical revolution, allowing precise interpolation by the control electronics. The multi-turn absolute encoder reports the axis position immediately after power is restored, eliminating the need for a homing cycle in supported applications. Command and diagnostic data travel through the integrated Multi-Ethernet port, which supports common industrial Ethernet protocols for coordinated motion. The actuator has a motor size of 041, providing a compact format for space-limited machine axes. It couples to machinery through a plain shaft, which is suitable for clamping couplings and other keyless connections. The unit does not include integrated safety technology, so external safety devices must supervise motion when the application requires safety-related control.
