need some help with Chinese VFD also using MX 4660 and smooth stepper and Mach 3
i've double check the wiring everything is correct but I'm having trouble with the settings and Mach 3
if anybody be willing to work with me to get this figured out because I am pulling hair
when I start the spindle it runs 7174 but I can't change the speed at all
thanks much
Similar Threads:
so I changed the wiring from the VFD to the MX4660 per the instruction from Leadshine manual and the spindle starts and is running at about 15000rpm no matter if I input a speed or just start the spindle
an I get 1.1 volts across port "+10vdc in" and the GND and still can not changed the speed in mach 3
answer your last question is yes
PD001=1
PD002=1
PD003=300
PD004=300
PD005=300
PD006=2.5
PD007=.50
PD008=220
PD009=.13
PD010=6.5
PD011=11
PD013= Nul
PD014=5
PD015=5
PD044=1
PD070=0
PD071=20
PD072=300
PD073=120
PD141=220
PD142=8.6
PD143=2
PD144=2000

Mach3 can be tricky to get right which seems to be where your problem is, if you have no voltage change then something in the Ports and Pins may need to be changed
All your basic settings look ok
PD144 should be 3000 for it to work correct
Jumper J1 set to 1-2
PD044=02 default this is not normally changed
PD174= ??? ( To Be Set to the VFD Drives Max Rated Output Amps )
Mactec54
Jumper J1 in on 1-2
I will check PD044 and change it to 2
I will also check PD174 and set it to the correct amp of the motor not sure were it is at this time
be back at it tomorrow afternoon doctors apt in morning
Thanks for your help so far
fyi I'm getting PWM errors also
Later
IQUOTE=mactec54;2329880]PD144=3000 not 2000 this should get you to your spindle max 18,000RPM with KeyPad control
If you are getting a PWM errors then you need to look at your wiring there could be a problem how you have this connected[/QUOTE]
I changed the Pd144 to 3000 and running it with keypad it ran at 17952 close enough for me
the slowest I could get the Spindle to run is 9000 using my hand held. Digital Tachometer
the PD174 was at 11.0 and I could not change it to any thing else
I contacted Leadshine and he stated that The PIN14 of DB25 is used for PWM signal transmission and to Configure pin14 for spindle control so that leaves me to these pic
I also was correct with the wiring per Leadshine

Ok I see another Parameter problem with the minimum speed is your spindle air cooled or water cooled ???
PD011=120
What is the Breakout Board you are using
Mactec54
It is air cooled
the breakout board is a Lendshine MX4660
I will check on PD011
PD011=120
I did some research and found that one other user of the MX4660 was testing his Estop button and the MX failed so they replace the unit and he installed a jumper on the to E-stop ports and he never connected the button again.

Ok I will look at the manual
So what I found was they are using the 12v supply from the MX4660 to power the 10v supply, not the 10v supply from the VFD Drive
(1) Used MACH3, settings: PWM Base Freq. = 10, Minimum PWM = 0%,
(2) Used “+12Vdc Out”, the 12VDC auxiliary power output on the MX4660 as the power input for “+10Vdc in” of the VFD (The measured value of the “+12VDC auxiliary power output of the MX4660” was?11.98VDC.).

Hay Thanks for all your info (HELP) but I'm going with a RS485 connection instead of using the MX4660 for spindle control. It will do what I want it to do, at least that what he said on the CNCnutz Episode 147
and I only need one twisted pair of wires from the RS485 to the VFD do some config on each of the units and I should be up and running. I will only use the MX4660 for the Axis.
The RS485 should be here on Friday. I will down load the Plugin from this web site https://www.cncnutz.com/2017/05/mach...trol-with.html. This plugin is only use for the Huanyang inverter
I will let you know how it turns out
