Frequently Asked Questions

How does the optical multiturn Hiperface encoder (M1, 128 periods) improve commissioning and control accuracy on the MSK101C-0300-NN-M1-BP2-NNNN?

The M1 Hiperface encoder preserves absolute position over revolutions and supplies high-fidelity phase information for reducing homing moves and improving loop bandwidth. Its 128 signal periods deliver fine interpolation for precise velocity and position regulation under dynamic load.

How do the standstill torque ratings (48.0 Nm generic; 36.5 Nm at 100 K) guide continuous-duty motion profiles?

The higher catalog standstill torque assumes specific test conditions, while at 100 K winding rise its continuous torque is derated to 36.5 Nm. It is important to use the thermally limited value for RMS sizing and to reserve peak capability for transient segments.

What integration advantages come from the B-side power connector on MSK101C-0300-NN-M1-BP2-NNNN?

The B-side exit aligns cable strain relief away from machine datum surfaces, easing routing in tight cabinets and gantries. It also separates power and feedback harnesses to reduce EMI coupling and simplifies service loops.

How does the keyed shaft of MSK101C-0300-NN-M1-BP2-NNNN affect coupling choice and torsional stiffness?

The keyway provides positive torque transmission and anti-slip under shock for enabling standard taper-bush or clamp couplings. For high-precision backlash targets, pair with preloaded bellows couplings and perform encoder-to-mechanics alignment per Rexroth procedures.

For multi-axis cells, how does using MSK101C-0300-NN-M1-BP2-NNNN influence safety and enclosure design?

The MSK series motors typically ship with IP65-grade housings for easing washdown protection and dust ingress control when paired with appropriate connectors. Its convection-cooled bodies reduce fan maintenance.
