What software are you using on your drone ? Ardupilot or PX4 ?

You issues are likely setup related , we would need a lot more info, I would suggest you insrall Mission Planner or QGC and follow the setup guides on your flight stack

Throttle value is very high , I want to trim throttle value in herelink  
when I connect cube with normal Remote controller it is working fine.  
but when I connect with herelink it creates problem.

Did you recalibrate the RC calibration in ardupilot after switch from rc controller to Herelink?

You may also try to re-calibrate ESC and see if the problem still exist.

Maybe you need to tune the hovering throttle?
