Product Description:
The MSK070D-0300-NN-S2-UG1-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within an automation cell, it works as the rotary actuator that delivers precise position and velocity control to a matched drive. Because it is a synchronous servo motor, it is intended for applications where dynamic response and repeatability are more important than simple constant-speed operation. It is suitable for indexing tables, pick-and-place heads, and format-change stations that demand repeatable movement.
Thermal management relies on natural convection, so the installation must allow free airflow around the housing. Mechanical runout is kept low by the increased concentricity design, which helps reduce cyclical speed error at high servo gains. Electrical terminations for the optical feedback are simplified by a rotatable 240° encoder connector that can be swiveled to avoid cable strain. Position data are exchanged through the EnDat2.1 interface, providing bidirectional communication for diagnostics and automatic parameter transfer. The optical measuring system resolves rotor position into 2048 signal periods, enabling fine interpolation inside the drive controller. A fail-safe holding brake is integrated and is electrically released, so it clamps the shaft when power is removed and releases it during motion commands. The motor has frame size 070 and length code D, while winding code 0300 corresponds to the electrical characteristics used for its speed and torque behavior.
The encoder uses optical sensing and is configured as a single-turn device, reporting absolute position within one mechanical revolution without multi-turn counting. That feedback arrangement supports accurate commutation and helps the control loop maintain stable positioning after startup. During machine downtime, the brake can resist up to 23 Nm of static torque, helping keep vertical or load-biased axes from drifting. Output power is transferred through a plain shaft, allowing direct coupling with backlash-free clamps or keyed hubs supplied by the machine builder.
