Hi,
I have a Huanyang Inverter, 2.2kw Air Cooled Spindle. I will be using Mach3. I'm using a G540 along with an ESS SmoothStepper.

I am trying to figure out what the pulley min and max should be set to in Mach3. I'm thinking the minimum spindle speed needs to relate to the VFD Parameter PD011 & PD73 equaling 200 but I'm not sure.

Huanyang VFD parameters:
PD000=0 for Parameter unlock. (1 for Parameter Lock)
PD13= 08 is for Factory reset, Only use this to set VFD to Factory Default Settings
PD001=1 (1 for external Control, Mach3. 0 for VFD front panel buttons, 2 for RS-485)
PD002=1 (1 for external Control, Mach3. 0 for VFD panel buttons.) you also need the J1 Jumper set for remote use also
PD003=400 (My Spindle frequency is 400Hz)
PD004=400 (My Spindle frequency is 400Hz)
PD005=400 (My Spindle frequency is 400Hz)
PD144=3000 (Max Motor RPM. This makes the spindle rotate at 24,000 R/min)
PD007=20
PD008=220
PD011=200 (Minimum Setting 120Hz for water cooled spindle. 200Hz for air cooled spindle)
PD009=15
PD010=8
PD141=220 (My Spindle Motor Rated Voltage is 220)
PD142=8.5 ( Motor Max Amps) (Set for your motor Amp Rating 2.2Kw Spindle 9 amp Max.)
PD143=2 ( Motor Number of Poles)
PD014 Accel=15 (# of seconds to get to full speed. Adjust to suit. No lower than 12)
PD015 Deccl=15 (# of seconds to stop. Adjust to suit. No lower than 12) (PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)
PD70=0 (Analog input range. 0: 0-10V)
PD72=400 (maximum spped from the pot. My max spindle frequency is 400Hz)
PD73=200 (minimum speed from the pot. 120Hz for water cooled spindle. 200Hz for air cooled spindle)
PD000=1 for Parameter lock. (0 for Parameter unlock)
