General Mach Discussion / Re: Spindle Setup Trouble
« on: April 03, 2015, 10:56:06 PM »
I figured out the problem with the help of Steve Stallings at PMDX. PD072 was factory set to 400hz. My max is 105hz. I set PD072 to 105hz and ran the PMDX-107 calibration and was able to tune the spindle to the max speed. Now everything scales correctly.

General Mach Discussion / Spindle Setup Trouble
« on: April 03, 2015, 11:18:58 AM »
Hi All,

I am almost done with a belt drive conversion an my PM932 mill (RF45 clone). I can control the VFD/motor manually. I can turn the VFD/motor on and off with Mach3. I can slow and speed up the VFD/motor with the manual override but I cannot set the speed with an "S" command. With an "S" command I always get 100% spindle speed. I'm guessing it is a setting somewhere but I have no idea where to go from here.

This is my setup.

Mach3 R3.043.066, ESS plugin v10h2d1a

PMDX-126 BOB, PMDX-107 Motor Control, ESS Motion Controller.

MOTOR, 220v, 2hp, 3ph, 1725rpm, inverter duty, class F

VFD = Huanyang HY02D223B Settings

pd001 = 1, run command = external terminals
pd002 = 1, operating frequency source = external terminals
pd003 = 60.00, main frequency
pdoo4 = 60.00, base frequency
pd005 = 120.00, max frequency
pd008 = 220, max voltage
pd141 = 220, rated motor voltage
pd142 = 8.0, rated motor current
pd143 = 4, motor pole number
pd144 = 1725, rated motor revolution
pd176 = 60.00, inverter frequency standard


ESS Settings

SPINDLE
PWM, base hz 25


Mach3 Settings

RELAY CONTROL, disabled

MOTOR CONTROL
Use Spindle Motor Output
PWM Control
PWM Base Freq = 25
Minimum PWM = 5%

SPINDLE MOTOR TUNING
Steps per = 1000
Velocity = 60
Acceleration = 5000

PULLEY SELECTION
Pulley 1, Min Speed = 300, Max Speed = 6000, Ratio = 2 (4" motor pulley, 2" spindle pulley)
Pulley 2, Min Speed = 75, Max Speed = 1500, Ratio = 0.5 (2" motor pulley, 4" spindle pulley)
