Hi
i have a problem with my 4kw VFD with is a 4kw 18000rpm spindle
i can fine get the spindel to 18000 rpm and 300hz
but if i set the mach3 to 9000 rpm the the vfd is showing 174.5hz and not 150hz
and i have measured the pwm signal to 5v
now i have use two days and i cant find the error

Is your Spindle Air cooled or Water Cooled ???
PD014= you seem to have a high setting for this normally you can go as low as 3 so anywhere from 3 and up should work fine
PD015= you seem to have a high setting for this normally you can go as low as 3 so anywhere from 3 and up should work fine
Jumper J1 also must be set for Remote Control This is located next to the Terminal Block
PD002=1
PD011=120 Not 40 this is below the minimum speed for your spindle
PD70=0 ( This may need to be set to 1 if Control Voltage is 0-5v )
PD72=300
PD73=120
PD120=120 (Stall Prevention )
PD174=?? ? ( Your VFD Drives Max Amp Output Rating )
