Hello
Mactec54,
Its been almost an year since you tried to guide me on this. Thanks for pointing me in the right direction. Its never too late to say thanks. Life simply got in my way, lost my job, moving house, my stuff was all in boxes in storage, and I finally decided to rework this project again. So thanks again for all your help.
On the same note, I managed to finally control the spindle via Mach3. Apparently, the wiring instructions provided by the seller were completely wrong and as you suggested we do need a relay to Start/Stop the spindle via Mach3.
Here is the final info if anyone out there ever stumbles upon the same issue:
First, the wiring details provided by the seller are wrong.
The correct wiring diagram would be something as shown below:
The connection from the USB Motion Card to the HY VFD are as follows:
For Spinde speed control via Mach3:
DAC ---> VI
COM ---> ACM
For Spindle start/stop via Mach3:
O1 & V+ ---> Input Mechanical Relay (With Diode 1n4007 as shown)
Output Mechanical Relay ---> DCM & FOR
You will also need to ensure the J1 jumper is set to position 1-2 to enable VI mode for speed control.
Please note:
A Solid State DC/DC Relay does not work directly as the relay remains energized after sending spindle stop command from Mach3 even though there is no more signal via the O1 & DAC pins. You will need to use an electro-mechanical relay for the spindle to start/stop via Mach3 properly.
Electro-mechanical relays are very easy to find in any Automotive parts store, I just used a Bosch 12V 30A mini relay such as the one shown below and it only cost me like US$3.
The above will work perfect assuming you have setup your VFD spindle parameter according to your spindle specification and have also implemented the following:
PD001=1
PD002=1
PD070=0
PD044=1
Thanks again.
