Product Description:
The KSM02.1B-076C-35N-M1-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. With a frame size of 076 and length code C, this compact unit combines the motor and drive electronics in one housing to simplify cabinet wiring in distributed automation. By placing the inverter directly on the axis, it reduces the amount of separate hardware that must be mounted elsewhere on the machine. It is a basic performance level unit with design version 1 and Series 2, intended for decentralized control in packaging, material-handling, and assembly stations where installation space is limited.
The drive draws power from a DC 750 V supply rail created by the central power supply module, and winding code 35 is matched to the motor's electromagnetic characteristics. Field cabling is reduced to a single Hybrid Connector that carries DC power, logic supply, and network wiring in one bundle. Command and diagnostic data travel over Multi-Ethernet, enabling the unit to accept EtherNet/IP, Sercos over EtherNet, or PROFINET frames without hardware changes. Heat is removed by natural convection, so no forced-air fans are required and sealed machine sections do not need dedicated fan hardware for this axis. Position holding during line interruptions is provided by an electrically released brake energized at 24 V DC, and spring force clamps the rotor when the control voltage disappears.
Rotor position is measured by a Hiperface optical encoder that delivers 128 signal periods per revolution and supports multi-turn absolute tracking after power cycles. This feedback arrangement gives the control loop continuous position information for commutation and positioning tasks during normal operation. The plain shaft includes a shaft seal that helps limit lubricant migration and supports direct connection to couplings or geared stages. Absolute position retention after restart can reduce the need for a full homing move on machines that must resume motion quickly.
