In your situation --1st check cnc 805 NC machine Data --I did not check the number but there is a data in the range of 4000 higher it setting tolerance for spindle speed reach in setting range such as 1% , to see you make that data larger may be 5% to see what happen. If no help, possible issue in the drive. I am not 100% sure but quit sure it is NOT drive (power section )problem I attached manual , you can check section HS(German) --English MS You need to get idea the actual spindle speed and set speed, I mean speed set on the spindle drive --you can check from drive LCD display (P001 or P002 making sure by yourself ) so you will know speed is really reached or not. Is encoder transfer issue or ramp up time too long or something else. another tip is replace spindle control card that will be more cost. i don't have same case but have more easy--finding case--spindle speed not reach at all--there are in control card programable relays named A 1, A2,.... one of them failed to working --it is giving out signal to PLC (inside CNC). to inform system "Speed reached setting " --I reprogrammed it and changed wire to anther Ax which not used. for those operation you need to read the books and very familiar the machine drawing if you can send me machine drawing spindle drive pages , I may help you to make modification
