Frequently Asked Questions

How does the S1 Hiperface single-turn (128 periods) feedback on the MSK076C-0300-NN-S1-U influence servo loop tuning and precision?

The S1 encoder provides single-turn absolute position over a Hiperface interface that gives the drive clean rotor-position feedback for commutation and positioning. It supports tight velocity/position loops and consistent low-speed behavior on demanding axes.

How does the 240° rotatable plug on MSK076C-0300-NN-S1-U simplify electrical layout in compact frames?

The connector can be clocked through 240° for aligning cable exits with energy chains or glands while honoring bend-radius rules. Its orientation freedom also improves tool access for service without disturbing cable terminations.

Is an electrically released holding brake available for MSK076 variants, and how is it characterized?

Yes, the MSK076 size offers a type-code option with an 11 Nm electrically released brake, alongside versions without a brake. It accounts for added inertia and specified release/disengage times in stop calculations.

What environmental/protection characteristics are typical for MSK076C-0300-NN units?

It has IP65 protection, insulation class F and an operating ambient of 0–40 °C with natural cooling. It suits enclosure conditions and any washdown or dust-exposure requirements.

During commissioning, what signals does the Hiperface encoder on MSK076C-0300-NN-S1-U provide to the drive, and why?

The integrated encoder system delivers rotor-position information required for speed control and positioning. Its drive must be configured and programmed prior to startup so the motor executes the intended application functions safely.

Internal Product Review

The Bosch Rexroth Indramat’s AC motor MSK076C-0300-NN-S1-U uses natural-convection for cooling and has a 240° rotatable plug for tidy cabinet routing. It comes with an S1 Hiperface optical single-turn encoder that delivers 128 periods for accurate positioning. This unit has a specified size of 076 and length C, while its winding targets mid-speed axes that makes it ideal for packaging, printing and metal-forming stations.
