Good day guys
I need some help. I have a 6090 Chinese router which was set up with Richauto DSP A11s controller. I have now changed the controller to mach3 parallel port controller with a standalone pc. All works as it should accept for the Spindle not reaching it maximum of 24000rpm. it is connected to a Fuling DZB280B002.2L2DK VFD, using the 0-10v port on the controller connected to the VI pin on the VFD. The spindle turns on as it should and the speed increases and decreases with MACH3.
Mach3 set to 24000rpm the VFD reads 200Hz and the 0-10V pin is at 10 volts
Mach3 set to 10000rpm the VFD reads 100Hz and the 0-10V pin is at 5.5 volts
Mach3 set to 0rpm the VFD reads 0Hz and the 0-10V pin is at 0 volts
This leads me to believe that the Mach3 and the controller is working as it should. I have been through all the settings on the VFD But can't figure out what the problem is. This is the VFD setup
F0.00 = 0
F0.01 = 1
F0.02 = 0
F0.03 = 1
F0.04 = 400HZ
F0.05 = 400HZ
F0.06 = 10HZ
F0.14 = 0
F1.00 = 1
F1.01 = 2.2KW
F1.02 = 400HZ
F1.03 = 24000RPM
F1.04 = 220VOLTS
F1.05 = 8.0AMPS
F1.20 = 0 LINEAR V/F CURVE
F1.21 = 0 AUTO TORQUE BOOST
F2.01 = 1 FORWARD
F2.02 = 2 REVERSE
F2.09 = 0.00V VI LOWER LIMIT
F2.10 = 0.0% VI LOWER LIMIT
F2.11 = 10.0V VI UPPER LIMIT
F2.12 = 100% VI UPPER LIMIT
All the other settings are at the default values. I did reset the VFD before using these settings.
Any help with be appreciated.
