There is NO connection
They are correct, that is just arbitrary numbers, and have no effect on how the spindle runs
The only thing that controls your spindle is your VFD Drive, from the control the PWM to Analog 0-10v plus the 0n / 0ff Relay connection
If you disconnected the 0-10v and the Relay connection, the VFD Drive is the only part that controls your Spindle, which would then be from the KeyPad which will run it at the correct speed
The only adjustment you can try to get right from your control is the accuracy of the 0-10v output if this is 0ff then your speed will be 0ff as well
