Product Description:
The KSM02.1B-041C-42N-M1-HP2-ET-SD-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat's KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor, drive electronics, and the communication interface in one enclosure, it provides decentralized axis control for packaging, material-handling, and assembly lines. This integrated layout places the drive directly at the machine axis and reduces the need for separate cabinet-mounted motor control hardware at that location. The unit is part of Series 2 and uses a basic performance level for precise, moderate-torque applications where installation space is limited.
The drive accepts DC 750 V bus power through a Hybrid Connector that combines power, signal, and safety connections in one plug. It uses natural convection cooling, so no fans are fitted and the housing must be mounted vertically for proper heat dissipation. An Hiperface optical encoder provides 128 signal periods per revolution, and its multi-turn absolute memory restores position after power is cycled. This feedback arrangement gives the control system immediate position information after startup and supports closed-loop motion without a homing move in many installations. The unit uses the standard design option and design version 1 electronics, with winding code 42 and motor size 041 in a length C frame.
Control data reach the axis over Multi-Ethernet, allowing network operation with SERCOS III, EtherNet/IP, or PROFINET. For functional safety, the unit supports Safe Motion with integrated safe brake control. Its spring-applied, electrically released holding brake engages automatically when the 24 V DC release line is removed, so the axis can remain held when control power is no longer present. Mechanical output is delivered through a shaft with a keyway, and a shaft seal helps limit lubricant escape and particle ingress. This arrangement suits direct coupling to driven machine elements that need positive torque transmission through a keyed connection.
