|---|---|---|---|
| Alias intent was not explicit enough for 150 mm integrated-controller buyers. | Users searching the long-tail phrase could miss that the canonical page already answers their exact use case. | Added explicit alias intent section, dedicated anchor links, and FAQ entries targeting the full phrase. | Closed |
| Tool output previously lacked traceability to source-backed constraints. | Without source mapping, boundary labels looked like opaque scoring instead of auditable engineering screening. | Added evidence table with dated sources and mapped key checks to pulse, life, torque, and stage capability references. | Closed |
| Microstepping was easy to misread as guaranteed accuracy gain. | Procurement teams can overestimate positioning capability if they treat command resolution as absolute mechanical accuracy. | Added ADI + Oriental Motor evidence showing microstepping increases command resolution but does not remove load/tolerance limits. | Closed |
| Comparison layer did not normalize 150 mm vendor datapoints. | Without a normalized benchmark, teams could compare marketing claims without speed/load/precision context. | Added a dated 150 mm benchmark table with integrated-stepper and servo-class counterexamples, including N/A markers when data is unpublished. | Closed |
| Critical speed and DN constraints were not visible in first-pass checks. | Axis plans can pass thrust checks but still fail due to screw rotational limits and resonance risk. | Added THK critical-speed/DN boundary references with explicit safety-factor context for pre-procurement screening. | Closed |
| Comparison layer did not separate integrated controller stages from external-drive architectures. | Buyers could mix incompatible assumptions when comparing commissioning effort and control stack risk. | Added architecture-level comparison matrix with fit scenarios, integration effort, and risk warnings. | Closed |
| Public data for thermal derating across all 150 mm stage vendors is incomplete. | A single universal duty-cycle threshold would overstate certainty and could mislead deployment decisions. | Kept thermal index as a screening indicator and marked final derating as pending vendor datasheet confirmation. | Open |

150 mm linear translation stage with integrated controller stepper motor:
El metodo es auditable y cada conclusion enlaza a evidencia con fecha.
| Metrica | Formula | Uso |
|---|---|---|
| Linear speed capability | v_max = lead x RPM / 60 | Checks whether the requested cycle time can be met before adding load and derating effects. |
| Pulse demand | pulses/mm = (360/stepAngle x microstep)/lead; f = pulses/mm x speed | Maps kinematics to controller pulse bandwidth, which is often the hidden bottleneck in integrated systems. |
| Linear force screening | F_req = (m_total x a) + friction | Captures acceleration + friction load, then compares with published thrust capability and torque-derived screw force. |
| Screw torque estimate | T_req = F_req x lead / (2pi x eta), eta screening range 0.90-0.95 | Used for first-pass fit with THK efficiency context. Final confirmation still requires model-specific torque-speed curves. |
| Critical speed / DN guardrail | n_cmd <= min(0.8 x n_critical, n_DN_limit) | Screens screw rotational feasibility before approving RPM assumptions. Passing thrust checks alone is not sufficient. |
| Microstep boundary check | resolution = stepAngle/microstep (commanded), accuracy != resolution | Separates command granularity from real loaded accuracy so microstep ratio is not used as a standalone precision claim. |
| Life proxy (guide/load ratio) | L10_km ~= 50 / (P/C)^3 using a simplified load-ratio model | Conservative screening inspired by linear-guide life relations; not a replacement for full vendor life calculation. |
| Thermal stress index | thermalIndex = (F_req / F_available) x duty x ambient factor | Flags when duty cycle and ambient push the system toward derating risk even if static force checks pass. |

|---|---|---|---|---|
| Pulse and speed feasibility screen | Pulse-input architecture is used and required pulse frequency stays below published controller limit with margin. | Axis uses non-pulse command modes or hidden firmware limits cap usable pulse bandwidth. | Confirm command mode and frequency limit in controller manual before release. | E3, E4, E6, E7 |
| Torque estimate from force-to-screw conversion | Screw efficiency is within known range and preload/friction assumptions are realistic. | Unknown screw condition, atypical preload, or unmodeled friction dominate runtime torque. | Replace screening inputs with measured torque-speed data at target RPM. | E2, E13 |
| RPM plan from lead and motor speed | Commanded screw RPM remains below critical-speed and DN boundaries. | RPM planning ignores resonance/critical-speed limits or shaft support changes. | Add critical-speed and DN check before locking lead/RPM combination. | E12 |
| Microstep-based precision expectation | Used as command-resolution aid with load-aware validation. | Used as a proxy for guaranteed absolute positioning accuracy. | Validate repeatability/settling under real load instead of assuming microstep ratio equals accuracy gain. | E10, E14 |
| Life and thermal decision from public data | Used as first-pass screening with explicit duty/load assumptions. | Used as universal pass/fail without vendor-specific derating curves and moment checks. | Run model-specific life/thermal validation before procurement sign-off. | E1, E9, E11 |

|---|---|---|---|---|
| Universal thermal derating curve for all 150 mm integrated stages | Vendors publish model-specific limits and conditions, but no cross-vendor universal curve with harmonized test method is publicly available. | Any single temperature/duty threshold would overstate certainty and risk wrong architecture choice. | Treat thermal index as screening only; require model-specific thermal logs before release. | Pending |
| Cross-vendor life data under identical load-moment profiles | Life and MTBF are reported under different loads, duty cycles, and moment assumptions. | Direct life comparison without condition normalization can mis-rank options. | Normalize to your duty/load profile and re-calc with vendor tools before PO. | Partially closed |
| Controller firmware-side pulse handling limits for every integrated model | Public pages often list headline frequency limits but not all firmware constraints. | Designs near pulse limit may pass brochure checks but fail commissioning. | Confirm command mode + pulse handling in model manual and run bench frequency sweep. | Pending |

|---|---|---|---|---|
| 150 mm integrated controller stage (lab/inspection class) | High precision, lower integration friction, moderate speed envelope | Low wiring complexity; vendor software + USB/fieldbus options | Measurement fixtures, optical alignment, quick deployment with traceable accuracy | Higher unit cost; vendor lock-in on control stack and accessories. |
| External driver + screw stage + NEMA23 | Wide speed/current tuning range, easier BOM substitutions | Medium to high; tuning, shielding, I/O mapping, and protections handled by integrator | OEM machines that need cost control and custom axis architecture | Commissioning risk rises quickly if pulse, EMC, and deceleration voltage are under-modeled. |
| Closed-loop integrated stepper package (24/48 V) | Better anti-stall behavior and diagnostics than open-loop stacks | Medium; still needs controller protocol and safety mapping | Medium-load automation where missed-step risk must be reduced without full servo migration | Thermal and life outcomes still depend on duty cycle and mechanical loading, not only control mode. |
| Servo + ball-screw axis module | Best dynamic margin and control bandwidth for aggressive throughput | High; cost, tuning, and safety validation are heavier | High-cycle production lines where acceleration and throughput dominate ROI | May be over-specified for intermittent 150 mm positioning tasks. |
