Gimbal rate control px4


I have a herelink remote controller, a cube orange and a gremsy t3v3. I have connected my SBUS1 from herelink to RCIN of the cube and have established manual control of the gimbal using the AUX in ports (which are mapped to herelink channels). However, using MNT_MAN_PITCH/YAW/ROLL I’m currently controlling the angle instead of the rates. Does anyone know what I can do to obtain rate control?
