Frequently Asked Questions

What practical impact does the 6,000 mH winding inductance have on current response and control bandwidth?

A high inductance slows the current rise (dI/dt), requiring more drive voltage or slower current loops to avoid overshoot. In high-dynamic applications, the drive tuning must account for this inductance to maintain stable control.

What shaft load limits should I observe on the plain shaft design?

The motor datasheet specifies allowable radial and axial forces (e.g. ≤ 500 N axial for size MSK101) that must not be exceeded to avoid bearing damage. Exceeding these can reduce bearing life or cause shaft misalignment.

How does the Hiperface (optical singleturn) encoder interface influence cable layout or shielding requirements?

Hiperface being a differential optical protocol is sensitive to noise, so feedback cables must be shielded, twisted, and routed away from power or high-frequency lines. Any cable length beyond ~50–100 m risks signal attenuation or delay errors.

In a CNC machine, how would you size a drive to fully exploit the 160 Nm peak torque?

The drive should supply up to 99.9 A peak (per spec) and have sufficient voltage headroom to overcome back-EMF at desired speed. The mechanical system (gearbox, inertia matching) must also handle torque transients without exceeding torque limits.

For B2B automation integration, how does the flange (B5) mounting facilitate modular system design?

The standardized B5 flange simplifies direct mounting to machine modules or gearboxes with minimal alignment, supporting modular machine architectures. It also allows using pre-engineered coupling plates or drop-in swaps between models in the MSK family.
