KSM02.1B-061C-35N-S1-HG0-ET-SD-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-S1-HG0-ET-SD-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By placing the power electronics on the motor frame, the unit simplifies cabling and supports decentralized positioning tasks on packaging machines, material-handling gantries, and assembly stations. The drive belongs to Series 2 and has a basic performance level for executing single-axis motion sequences. Its decentralized architecture distributes control functions directly at the axis and reduces the amount of heat generated inside the control cabinet.

The power electronics operate from a DC 750 V bus supplied by a central converter. A hybrid connector carries power, feedback, and communication signals through a single cable, reducing the number of separate field connections. Thermal energy is removed through natural convection, eliminating the need for cooling fans. Position feedback uses a Hiperface interface connected to an encoder that provides 128 signal periods per revolution. The optical encoder supplies accurate rotor position information for closed-loop control. Winding code 35 is matched to motor size 061 and motor length C, while Design Version 1 includes an external master communication module that uses the Multi-Ethernet protocol family to connect with the automation network.

The feedback system transmits absolute rotor position in a single-turn data format, which is suitable for indexing axes that perform a homing sequence after startup. The integrated circuitry supports Safe Motion with SBC, enabling safe torque off, safe stopping, and brake control functions within the drive system. A plain shaft with a shaft seal provides a direct connection to gearboxes while helping prevent contaminants from reaching the bearing area. The motor is supplied without a holding brake, so the machine must provide static load retention when power is removed. Its basic design supports moderate dynamic response without requiring an oversized power stage, and the lack of a holding brake reduces the motor assembly's overall mass.
