Is the measured encoder speed scaling (MAX RPM) inside the control loop or not ?

I use the controller in closed loop speed mode with an optical encoder.

Does the scaling of the optical encoder speed (MAX RPM setting) influence the control loop or is it outside this loop?

I cannot find it in the documentation. In Figure 41 of the user manual it is not clear whether it is / is not in the control loop.

It seems to me that it is outside the loop because if I change the MXRPM setting the control behaviour like settling time etc. looks the same.


I would like to know whether it is in or outside the control loop ?


Thanks, Herman

Hello Herman,

There are 2 configuration values. The one you mentione, "Max Speed (RPM)" or MXRPM and "Position Mode Velocity (RPM)" or MVEL.

What will be taken into account as maximum speed in a closed loop is the minmum of these two configuration values.
