Startup & recovery
Decide whether the axis can home safely and how position should recover after power loss.
TECHNOLOGY / ENCODER ARCHITECTURE
Incremental vs absolute encoder: which feedback system should you choose?
Compare position availability, homing, interface, system recovery and motion requirements.
ENGINEERING CONTEXT
The decision starts with the real constraint.
Incremental encoders provide relative position changes and commonly use a reference signal; absolute encoders return a position code. The right choice follows machine behavior, not a universal ranking.
Discuss your requirement ↗CRITICAL REQUIREMENTS
Define these before model selection.
Interface
Match differential incremental signals or digital absolute protocols to the controller.
System risk
Consider travel limits, collision risk, cycle time and calibration strategy.
SOLUTION ROUTES
Continue from requirement to system.
EVIDENCE CHECKLIST
Ask for evidence that closes the decision.
- Interface timing
- Homing/recovery sequence
- Resolution and accuracy budget
- Motion profile
TECHNICAL REVIEW
