Frequently Asked Questions

How does the EnDat 2.1 singleturn encoder on MSK076C-0300-NN-S2-UP1-RNNN improve servo feedback determinism and wiring simplicity?

The EnDat 2.1 is a digital, bidirectional serial interface that carries absolute position and parameters over just a few conductors for simplifying harnessing and EMI management. Its singleturn feedback ensures precise absolute angle within one revolution without homing.

What application niches benefit from the 11 Nm electrically released holding brake on product code MSK076C-0300-NN-S2-UP1-RNNN?

The released-type brake provides secure static holding for vertical Z-axes, indexers or conveyor tensioning when power is removed for preventing load drift. It’s well suited to packaging heads, pick-and-place gantries and woodworking spindles.

How does the 240° rotatable encoder connector aid cabinet and machine integration for MSK076C-0300-NN-S2-UP1-RNNN?

The swivel connector allows stress-free cable exit optimization for reducing bend radius issues and facilitating tool-less reorientation during commissioning. It also improves serviceability in dense multi-axis racks and articulated robots.

How does the shaft with keyway (DIN 6885-1) on MSK076C-0300-NN-S2-UP1-RNNN influence coupling selection and backlash control?

Its keyed shafts simplifies rigid hub coupling and pulley mounting while providing torque-safe transmission without shrink-fit tooling. Its zero-backlash beam or disk couplings maintain positioning fidelity.

For MSK076C-0300-NN-S2-UP1-RNNN, how does the winding inductivity of 12,600 mH interact with current loop bandwidth and drive tuning?

The higher phase inductivity filters current ripple but demands appropriate current-loop bandwidth and voltage margin from the drive. Its PI current regulation is important to maintain dynamic torque response without overshoot.
