The R911308689 (MSK030B-0900-NN-M1-UP0-NNNN) is a Rexroth IndraDyn S synchronous servomotor featuring a dual encoder system that supports both incremental and absolute feedback via a Hiperface interface, using optical multiturn absolute technology with a resolution of 128 signal periods and an accuracy of ±80 angular seconds. The servomotor features a shaft with keyway and sealing ring and is designed without a holding brake. Key specifications include natural convection cooling, rotatable 240° encoder connector, winding code 0900, continuous current at standstill of 1.7 A, continuous torque at standstill of 0.4 Nm, maximum current of 6.8 A, maximum torque of 1.8 Nm, and inductivity of 8,100 mH. The motor is designated as size 030, length B, in standard design, and is recommended for use under 3K4 climatic conditions, avoiding excessive vibration and maintaining appropriate air temperature and humidity.

Frequently Asked Questions

What is the advantage of the 240° rotatable encoder connector?

The rotatable connector allows flexible cable routing and simpler installation within compact machine frames. It helps reduce mechanical strain on the encoder interface in tight layouts.

How does the multiturn absolute optical encoder affect accuracy?

The multiturn absolute encoder retains position even after power loss and offers high resolution of 128 signal periods. It enhances repeatability and eliminates homing steps in cyclic motion.

Why is natural convection cooling chosen for this motor design?

Natural convection requires no forced air or fan, reducing mechanical complexity and maintenance. It is suitable for moderate ambient conditions and relatively low continuous power densities.

What does 8,100 mH winding inductivity imply for drive control?

A high inductivity smooths current ripple and filters high-frequency noise, aiding stable torque control. But it also slows current dynamics, requiring drive tuning to maintain responsiveness.

How important is the shaft keyway and sealing ring in industrial use?

The keyway ensures positive torque transmission to loads without slippage, while the sealing ring protects the internal bearings from contaminants. This matters especially in dusty environments like packaging or printing.
