Brains Development / Writing values to vfd.

« on: March 05, 2015, 02:39:21 PM »

I have my VFD working with Mach3's serial test utility. I can stop, rev and change frequency.
 My question is how can I send a value such as 1770h or 6000 to single register such as 02h from a brain?

Modbus / Re: Yaskawa GPD 315/V7 VFD Testing Communications

Hi,

The Modbus Configuration Screen slave address drop down lists 0-10, but I can enter larger numbers.  Do I enter decimal numbers and mach3 converts this to hex?

Thanks,

Modbus / Yaskawa GPD 315/V7 VFD Testing Communications

« on: February 25, 2015, 10:57:02 AM »

Hi,

I'm trying my first modbus setup and am having some trouble with addressing in Mach 3.  I've attached a pdf from Yaskawa covering command and monitor registers.
I need help with the Mach 3 communication testing.
The GPD315 VFD RS-232 port defaults to 9600 baud, 8-n-1 and is fixed.  My slave address is 1Fh.

How do I express my register values to Mach 3?
Thanks,
Hurco
