Who can I call to help me setup this automation direct vfd
« on: November 03, 2017, 07:53:15 PM »
I have been trying and I just can't figure it out
Who can I call to help me set this spindle control tru modbus?

I have a automation direct gs2 vfd.
I also have the USB to 485 from automation direct.

I looked at Most of the post on the internet but no just can't get it.

Thanks in advance.

Hi,
you were asking about a serial port:

Did my suggestion work, do you have an active serial port?

Hi,
on page 5.2 of the GS2 user manual:
P 9.00 default 01, this is the slave address, OK as is
P 9.01 default 01 transmission speed is 9600 baud, OK as is just set Modbus transmit to 9600 baud as well
P 9.02 default 00 ASCII, 7 data, no parity, 2 stop. The serial Modbus plugin of Mach3 does not have this combination, suggest 8 data, no parity,2 stop ie P9.02=03
Suggest you manully program the VFD with this parameter. You will also have to program the VFD to accept frequency and run commands from Modbus, but that
is a bit down the track yet.

The remainder of the parameters on this page do not concern us immediately.
On Page 5.3:
P 9.26 frequency command
9.27 Run/Stop value
9.28 Fwd/Rev value

While the alarm and status may prove useful in the future lets ignore them for the time being, they won't prevent us from getting the thing to run.
On page 5.8:
the decimal memory addresses:
P 9.26    42331
P 9.27    42332
P9.28     42333

Thus we have three consecutive input words.
On Function Cfg's/Setup Serial Modbus Control set up per the screen shot attached, I don't really know if I'm correct but it wont hurt to try.

Hi,
hopefully should be close to testing the Modbus communication link.
You'll need to read the users manual and program parameter P 9.02 with the value 03 as I alluded to in the last post.

Now with the Modbus Status and Control panel open <Test Modbus> will with any sort of luck produce an affirmative response.
What does it show you?

Hi,
I'm going to assume that the comm link is OK, that may be a bit optimistic, but we will see.

Now we need to program a brain that can output the three control words.
The inputs to the Modbus plugin are Mach3 outputs. I suggest you program Mach so that Output#1 is Run/Stop and Output#2 is Fwd/Rev.
The speed will be one of Machs DROs.
