Frequently Asked Questions

What issues might arise when using the MSK101D-0200-NN-S2-AP2-RNNN in multi-axis B2B systems?

In multi-axis setups, cross-coupling of power supply ripple or vibration can propagate through shared DC bus or mounting structure, so you’ll need decoupling (damping mounts, separate cabling) and proper bus regeneration/energy handling. Also, synchronous updates across axes require your controller to manage latency and feedback loops in large coordinate systems.

How must cable routing be planned given A-side power connection and EnDat encoder wiring?

The A-side connector means power and encoder cables exit from one side, so cable length, bend radius, and shielding must be managed to minimize interference and voltage drop. Keep sensor and power cables separated and twisted/shielded to suppress noise and avoid encoder errors.

In what way does 6,000 mH winding inductance influence dynamic performance?

High inductance filters current ripple and smooths torque, but also slows current loop response—limiting how fast you can aggressively change torque without overshoot. Your servo tuning must accommodate this, especially in high-acceleration moves.

What tradeoffs exist between continuous torque (57 Nm) vs peak torque (160 Nm)?

You can only apply the 160 Nm peak during brief transients before thermal limits constrain you, so your average load must remain near or below the continuous rating. Oversizing or periodic rests may be needed in high-duty cycles to avoid overheating.

How does the 70 Nm holding brake impact startup and shutdown sequencing?

The electrically released brake imposes a slight delay during energize (release) or de-energize (apply) phases, so your control sequence must account for that. If you command motion before the brake is fully released, you risk jerking or stalling; if braking before full stop, torque may overshoot.
