Ok. First, what is in the spindle? Collet? Chuck? Face plate? Etc.
Next. Was there a job running and now you have this alarm?
Or are you setting up a job?
Did you check the hydraulic system pressure and the main spindle closing pressure gage?

If you had a job running and now you get this alarm. It is either the zero speed circuit in the spindle drive or you have a bad collet proximity switch. If the collet/chuck opens and closes but you still have this alarm it is most likely the proximity switch. The control thinks the collet/chuck is open and thus in a non-safe state to run. I will try to check my Hardinge books for you on this matter.

HI, I trust you are well. Thank you for your time. I recently purchased this hardinge conquest t51 from UK in a used condition.
I powered it up first time in my works and this machine is on cycle start.
Machine is with Chuck. Also checked hydraulic system pressure and the main spindle closing pressure gauge.
When i open the chuck, chuck opens properly but certainly alarm appears 1020 chuck open on the screen.
