Frequently Asked Questions

How does the multiturn Hiperface encoder in MSK076C-0300-NN-M1-UP1-NNNN enhance absolute positioning and startup behavior?

Its optical multiturn encoder with Hiperface transmits sine/cosine tracks and digital data, so absolute position is available immediately after power-up without homing. Its 128 signal periods improves servo loop stiffness and low-speed smoothness.

What is the functional advantage of the 240° rotatable power/feedback connectors on MSK076C-0300-NN-M1-UP1-NNNN during machine integration?

The connectors can be rotated to align cable exit with the preferred conduit path for minimizing bend radius stress and simplifying panel routing. Its orientation flexibility also helps maintain IP65 sealing when union nuts are properly torqued.

Why is a keyed shaft specified, and how does it affect coupling selection for MSK076C-0300-NN-M1-UP1-NNNN?

Its shaft with keyway per DIN standards provides positive torque transmission and repeatable phasing for timing pulleys or rigid couplings. It reduces slip risk under transient torque and eases service alignment compared to plain interference fits.

How should the 11 Nm electrically released holding brake be sized relative to the 43.5 Nm peak torque on MSK076C-0300-NN-M1-UP1-NNNN?

The holding brake is designed for static holding and emergency stop positioning not for continuous dynamic braking. Its brake sizing resist axis backdriving under gravity or external load, while dynamic deceleration remains the drive’s responsibility.

What encoder resolution and interface considerations exist when integrating MSK076C-0300-NN-M1-UP1-NNNN with third-party controllers?

The standard optical encoder provides 128 signal periods Hiperface feedback, many controllers accept its sin/cos plus serial protocol. Its cable shielding, excitation and interpolation settings needs matching to avoid velocity ripple and phase lag.
