Q1.. Are you NOW controlling the VFD at it's console or externally via CNC Software?
Q2. The wirings to the Spindle is NOW correct?

If you can still program the VFD at it's console, I would just do a factory reset.

Answer Q1 and Q2 FIRST and I will post the parameter to change to do a FACTORY RESET.

If you are controlling by Computer program, how is the wiring from Computer to VFD?
Q3. Via 0-10V analog or Via MODBUS?

Don't do a factory reset YET since you are controlling via software.

19,200 could be just setting to 50Hz instead of 60Hz in USA.
50/60* 24000 = 20,000.

OR
If using 0-10V control - getting 8V instead of 10V.
