Frequently Asked Questions
How does the optical EnDat 2.1 multiturn encoder (2048 periods) on the MSK071C-0450-NN-M2-UG1-RNNN improve servo accuracy and diagnostics?
It gives high-resolution absolute position across revolutions for eliminating homing and stabilizing low-speed motion. Its EnDat 2.1’s bidirectional link exposes status/error bits and parameters, aiding commissioning, condition monitoring and closed-loop integrity checks.
What does “14.0 Nm continuous torque at standstill (100 K) at 10.4 A” mean for vertical-axis holding on MSK071C-0450-NN-M2-UG1-RNNN?
It means the motor can continuously generate 14 Nm in thermal equilibrium with natural convection when driven at 10.4 A RMS. Its integrated 23 Nm spring-applies for power-loss parking and electrically released brake provides mechanical holding capacity.
Why is the 6,700 mH winding inductivity significant on MSK071C-0450-NN-M2-UG1-RNNN?
The greater inductivity attenuates current ripple for improving torque smoothness and easing current-loop tuning for field-oriented control. Its trade-off is a longer electrical time constant that drives must accommodate with bandwidth, decoupling and feed-forward strategies.
How do the plain shaft with sealing ring and increased concentricity option affect coupling performance on MSK071C-0450-NN-M2-UG1-RNNN?
The sealing ring mitigates ingress and oil migration for protecting front bearings and couplers. Its elevated concentricity reduces runout for enhancing alignment for bellows or elastomer couplings and lowering vibration in precision indexers and gear stages.
What are the duty-cycle implications of natural-convection cooling, and when would surface or liquid cooling be preferable?
The natural convection supports continuous duty within the stated thermal class but limits overload duration compared with surface/liquid-cooled variants. Its alternative cooling are available for higher continuous torque density or tighter thermal margins.
