Someone asked me to post the actual brain that I'm using.  Here it is.  I should post the MODBus set up screen as well.

Thank you posting the info on WJ200.  I just purchased one and got it set up but
had now idea were to start.

From what I have read so far I use a com port from computer but what about the plug
on the WJ200.  Do you know were I can find a pin out of the cable or instructions on what
I need to make?

Thank you for the help.

You need an RS232 to RS485 converter if using com port.  You can also USB to RS485 converter.  A cheap converter from ebay didn't work for me with WJ200 I had to go with a B&B converter  http://www.bb-elec.com/product11.asp?sku=485ldrc9

Ouch!  I though I could just make a cable. 

Thanks for the link... I guess I'll be ordering one if that is the only option

Bringing this topic back up.

I am trying to figure out how to make teh WJ200 work with modbus.

My setup will be different - I will be running mine with a 60hz 2.5hp 3phase Baldor I am putting on a rong fu 30 mill drill.

I really want to understand how modbus works rather than just configuring it.

I watched the Mach videos from Peter but they are centered around his modio card his utility rather than setting them up manually.

Any advice on a easy to learn approach to setting this up?

Also - Are you guys using the RJ45 connector on the WJ200 for modbus? The manual reads like you have to use the SN/SP terminals.  Says the RJ45 is only for remote operator.

Did anyone find a cheap modbus adapter rs232 to rs485 they KNOW works with the WJ200? I have one that works with my X200 but was not sure on the WJ200.

Just to follow up and clarify my posts... I ended up controlling my spindle via the breakout board and never used the MOD bus.

A call to Hitachi confirmed that on the WJ200 the RJ45 port is NOT for the modbus connection. Here it is in the manual as well.

OK I confirmed I cannot run Modbus using the RJ45 on the WJ200. Works perfect on the terminals though. This is kind of nice because you can run the op panel on the RJ45 and still control via modbus on the terminals

I also did not need a fancy modbus controller. In fact mine was less than $6 shipped. Search for "New 9 PIN RS-232 to RS-485 Adapter Interface Converter" from seller id eherebuy in Roselle Park, New Jersey, United States if you want to see the exact one I bought.

I have it working off a built in serial port on one computer and a PCI Rosewill RC-03 2serial1Parallel card from amazon installed in a second computer. Both work great.



A link for as long as it will work to the RS485 adapter I confirmed worked with a WJ200

Couple of WJ200 setting things important to remember.

If you are using a brand new drive - Do the power test and verify the Drive works.

Then when ready, connect up and change:
A001 to 03
A002 to 03
Verify all your settings for com speed (c071 to c078)
then once everything is set/stored/saved
POWER OFF YOUR WJ200, wait 5 min (I waited about 1 min and it was fine), Then POWER IT BACK ON (or reset it) - You need to do that before Modbus control will work
TX+ on RS485 adapter to SP on the Hitachi WJ200
TX- on RS485 adapter to SN on Hitachi WJ200
Verify your serial port settings on the PC, make sure they match the inverter, and set those in Mach as well.
