Hello, I see following possibilities: 1)you use CU320-2 with CUA- Adapter, so you would get the DO external encoder and a actual speed value 2) with PositionController you will get the actual velocity in r2522[2] for the second encoder (note: it is possible to activate the positoncontroller standalone - so you would get the r2522[2] too. To deactivate the postioncontroller (if you use the Ramp-generator), you can set p2550 = 0). You have different diameter of the measuring wheel. You can change p408 for the external encoder in relation of your both wheels (but deactivate the zero pulse of the external encoder). 3) with DCC you have to know how many pulses you get per one revolution - so you can make one mechanical revolution and you will get a value (for example 4096). In the attachment "ExternalEncoderSpeed.pdf", I have a example how to make it, but I would recommend 1) or 2) - you get a rough signal, or you make a smoothing which creates dead time.

I use dp cu310 and SMC 20 SMC 20 for encoder 1 and X23 port on the 310 cu dp for encoder 2 |

I've seen examples of your dcc but where the output rpm |
