Do the point-to-point movement in the positive direction and check the available velocity telemetry as the following:
It looks there is the problem of cha_rate_fb and chb_rate_fb. Therefore, I put the rateCmd to do the comparison as well.
Put the negative direction below:
The data of rate A and B are written in 'rotator_smlink_controller' -> 'Control Laws & Profile Generators (4 khz)' -> 'Controller' -> 'Channel-A/B velocity loop' subsystem.
