The old version of the 1.5kw spindle kit can only adjust the speed through the panel knob, and cannot adjust the speed through the software.
Replace the speed control module in the old version of the spindle control box with this new version of the speed control module, and you can achieve software speed control. (Because the mounting holes are different, you need to fix the new module yourself)
Secondly, you need to modify the default parameters of the old version of VFD:
Change P0-03=4 to P0-03=2 Change P4-15=10 to P4-15=9.8
