I wonder about the raw value from encoder in drive.

It is speed feedback of drive.

What is the value from encoder which drive receive ?

Best Regards,

you have a CU320-2 with a CUA32 adapter. 

The actual speed of the encoder you get in r61 and the encoder raw value in r479 / r482. This value changes each revolution by p408 * 2^p418 (example p408=1024 and p418 = 2 => 4096 per revolutoin). By they way: The presetting of p418=11, but for a TTL/HTL encoder you have only a fine resolution of 2^2 (each edge of the signal change).

I like to actiave the function module "position controller" (or basic positioner). So if you only want to work in speed controlled mode you can deactivate the positon controller again with p2550=0 and reenable the speed setpoint enable by p1142=1. So you can normalize the encoder value and so on.

 Dear zako_

For this application it use only speed control it use AC motor it is winder machine.

I wonder about TL/HTL encoder you have only a fine resolution of 2^2 (each edge of the signal change).

Why TL/HTL encoder you have only a fine resolution of 2^2 ?

Hello,

Please refer below topics which shall help you to understand setting encoder fine resolution.
