Encoder resolution calculator

Linear & rotary positioning

Use this when you need linear µm/count or angular resolution from PPR, quadrature and gear ratio — before you buy an encoder or specify an IntelliLink protocol bridge.

Motion design

Quick resolution check before retrofit.

Use datasheet PPR values and real mechanics. For protocol conversion (TTL, EnDat 2.1/2.2/2.22, BiSS-C, SSI, Fanuc Serial, fieldbus), continue to the Encoder Bridge configurator.

Resolution inputs

Motion type Encoder PPR (lines per rev) Quadrature multiplier Gear ratio (motor to load) Ball screw lead (mm/rev)

FAQ

Questions plant engineers ask

Practical answers on encoder resolution planning — from Sharjah, for plants in the UAE and GCC.

When should I use this calculator?

Use this when you are sizing encoder resolution for a linear or rotary axis and need µm/count or degrees/count from datasheet PPR and mechanics. It does not choose the protocol — use the Bridge tools for that.

What does this calculator show?

Indicative resolution and positioning accuracy from PPR and mechanics. Confirm with your motion and encoder datasheets before procurement.

Does it replace encoder selection?

No. Protocol, mechanical fit, temperature and the controller interface still decide the encoder. This tool is for resolution only.

Need a protocol converter after sizing?

If the encoder signal does not match the CNC or drive, see the Encoder Bridge or send nameplate photos with a proposal request.

Do you work on site in the UAE and GCC?

Yes. SAS Middle East FZC is based in Hamriyah Free Zone, Sharjah. We survey, engineer and commission encoder resolution planning on site across the UAE and GCC.
