Hi Todd,
All things considered, this VFD seems to be one of the more difficult
to get the manual, and to understand the manual. The drawing in
Figure 4-11 shows conflicting information regarding how X1 to X6
operate. I have decided to trust the text in the manual rather than
this drawing since the text is less ambiguous.
You can download the manual here:
http://www.hy-dq.cn/download3.htmYou will need to alter the P0.01 and P0.02 parameters. They default to 0 for
front panel control. For control from the screw terminals both of these
parameters need to be set to 1.
You will also need to alter other settings if you are trying to run a 400 Hz
high speed router spindle. You can save this step until after you get
basic operation working.
The connections for this VFD and a PMDX-107 are as follows:
VFD PMDX-107
+24 COM
X1 FWD/RUN (for the default P3.01 setting of 1 for forward operation)
X2 REV/DIR (P3.02 setting must be changed to 2 to allow reverse command)
+10V Aref
AI1 Aout (for a setting of 1 in P0.01 for analog input on AI1)
GND Agnd
All DIP switches on the PMDX-107 should be in the off position assuming that
you have set up a "charge pump". If you do not plan to use a "charge pump",
turn ON the DIP switch labeled Config 4.
We highly recommend that you get the spindle to run using the Calibrate
test button on the PMDX-107 before moving on to configuring your Mach
software. This will confirm that the PMDX-107 and the VFD are working
with each other without the complications of software settings being
involved.
