Frequently Asked Questions

How does the EnDat 2.1 multiturn absolute encoder in MSK101C-0450-NN-M2-AG2-RNNN aid precise positioning and homing?

Its multiturn absolute feedback preserves position across power cycles for enabling deterministic startup without mechanical homing switches. Its EnDat 2.1’s serial interface and 2048 signal periods provide fine angle data the IndraDrive class drives can interpolate for tight loops.

Why is the 70 Nm electrically-released holding brake useful on MSK101C-0450-NN-M2-AG2-RNNN?

It secures axes at standstill and during E-stop, especially on vertical or overhauling loads for reducing drift when power is removed. Its safety guidance also recommends mechanically securing vertical axes during maintenance.

What is the benefit of an A-side power connector on MSK101C-0450-NN-M2-AG2-RNNN for machine layout?

The A-side orientation standardizes cable exit relative to the drive end for easing routing, strain-relief and service envelope planning. It explicitly defines connector side options (A, B, L, R) for layout repeatability.

How does “increased concentricity” in this motor’s design influence coupling accuracy?

The tighter runout improves shaft alignment for lessening cyclic radial forces on couplings and bearings. Its result is smoother torque transmission and better repetitive positioning with compliant or zero-backlash couplings.

What control implications stem from the 3,300 mH winding inductivity on MSK101C-0450-NN-M2-AG2-RNNN?

Its higher inductivity attenuates current ripple and PWM harmonics to improve current-loop stability at the expense of electrical time constant. Its drive tuning should balance bandwidth with thermal rise to maintain the specified standstill torque.
