Frequently Asked Questions

How does the Hiperface singleturn optical encoder in MSK076C-0300-NN-S1-UG1-NNNN aid servo precision and loop stability?

The Hiperface protocol carries absolute position per revolution with analog commutation plus digital data for improving interpolation and low-speed smoothness; optical sensing minimizes drift. It enhances current/velocity loops and simplifies drive commissioning with IndraDrive controllers.

How is the 13.5 Nm continuous torque at standstill (100 K) on MSK076C-0300-NN-S1-UG1-NNNN used in high-precision holding and low-speed feed axes?

At stall, the thermal model ensures continuous current capacity for creep feeds and dwell cycles without overheating. Its drive can overlay closed-loop control with the brake for secure holding during e-stop or vertical load retention.

How does the 32.4 A maximum current capability translate to motion profiles on MSK076C-0300-NN-S1-UG1-NNNN?

The peak current enables short-duration torque bursts up to the 43.5 Nm limit for fast indexing, acceleration or disturbance rejection. Its tuning follows time-at-peak and thermal limits dictated by the motor’s characteristic curves.

How does the electrically-released 11 Nm holding brake on MSK076C-0300-NN-S1-UG1-NNNN support vertical axes and safe torque-off strategies?

The spring-applied brake secures the load when power is removed or during STO to prevent drift on Z-axes. Its control logic blends torque hold and brake timing to avoid shock while meeting safety concepts.

What are integration considerations for the plain-shaft design on MSK076C-0300-NN-S1-UG1-NNNN in precision couplings or gearheads?

The plain shaft simplifies zero-backlash coupling selection and concentric gearhead mounting while minimizing runout-induced ripple. Its proper hub-bore fits, keyless locking and alignment practices to preserve encoder fidelity and servo smoothness.
