Speed feedback with encoder


Thread Starter

Mohammad Poury

calculating speed from encoder feedback in a dc motor position control system, need derivation of encoder output. i have many problem with this transformation.
Hi Mohammad,

If you need to use incremental encoder for tacho signal, you must transform A, B signals of encoder to Up/Down and Counts signals before F/V conversion. This need for bipolar tacho signals for feedback.

Don't hesitate to contact me for any help,

You Must Use Timer, We Assume Visual Basic Running Under Microsoft OS, So This Is Not Very Consistant
Because Of PC OS, Memory... etc. Status, How Ever Some Result Will Be Obtained If You Subtract The Current Encoder Position From The Previous Second Position.

Very Preferable, Need F/V Converter, Check Out US Digital ETACH Unit.
