The Bosch Rexroth KSM02.1B-076C-35N-M1-HP2-ET-SD-D7-NN-FW (MPN: R911389459) is a motor-integrated servo drive engineered for installation near machines, operating with a control section voltage of 30–42 VDC and a supply voltage of DC 750 V. The device utilizes a multi-turn absolute optical Hiperface encoder with 128 signal periods, supporting precise feedback. It features natural convection cooling, a hybrid connector, and supports multi-Ethernet master communication. The shaft, equipped with a keyway and seal, is paired with an electrically released DC 24 V holding brake. The drive has a rotor inertia of 0.00446 kgm², a maximum electrical speed of 4,700 min⁻¹, a power section dissipation of 165 W, a capacitance of 0.024 mF in the DC bus, and a thermal time constant of 25 minutes. Safe Motion technology with SBC is included. Flange mounting is secured with M10 screws at 51 Nm tightening torque, and correct signal and load wiring practices are recommended to minimize interference. Shaft fluid ingress should be avoided in vertical mounting (IM V3). Conductor termination is designated at terminal X103.2.
