Nevermind, I found the DRO you were referring to, it is called 'CMD Spindle RPM'

So i now can turn it on and set speed  :D

Hi,

Glad to see it is working.

Do you want to post the brain so that other owners of a Hitachi  can use it?

Cheers,

Peter.

I sure will.  I actully used 2 different brains for trouble shooting purposes.

Also I had to do 1 more little trick, instead of using the 'CMD Spindle RPM' value in the formula, I had to use the 'Spin RPM - Overridden' DRO so that spindle speed override would work :)

Also in the VFD Run brain I didnt concern myself with reverse, since I have a wood router and wont be using revrse much (if at all)

Thanks for all your help Peter!!!

I need to ask a embarrassingly basic question.  :D

What cable do I need to connect modbus to the SJ200 ?

Hitachi manual says, pin 5 send/receive data positive, and pin 6 send/receive data negative on the RJ45.

But no info on the computer end. Probably because it is so obvious that any fool would know.   ;D

Any one help?

Greg

Hi Greg,

You need an rs232 to rs485 converter. The rs232 end goes into the computer. The RS485 end connects to the X200.  You will have to make this cable up. The converters usually have screw terminals on the RS485 end and a DB9 on the RS232 end.

You will need to buy Something like this.

Cheers,

Peter.

Greg,

In addition to the 2 data wires, you also need a 0V line between the X200 and converter.

Cheers,

Peter.

Got my RS485 converter.   Set all the options for modbus in the Hitachi.  Think they are right.  ???

I have communication...but,

Reading and writing to coils looks to work.

Reading Holding Registers also seems to work.

Writing to Holding Registers just gives a timeout.

So I think this is why I can not get the spindle to run.    Can turn on the run and CW signals but can not set the frequency (RPM) so it does not run.

Any ideas what I am doing wrong?

Zigmart

Can you tell me what settings in the Hitachi you have for,  (my settings in parenthesis)

C070  .....NA in SJ200.  set via dip switch
C071  (05)
C072  (1)
C074  (00)
C075  (1)
C076  (02)
C077  (50)
C078  (10)

Probably only the last two are questionable.

I also have a X200.  So I tried the modbus with that.

Exactly the same result.   Read and write to coils OK.   Read holding registers OK.  Write to holding registers results in a time out.

Doing something wrong but have no idea what it is.

Tried all sorts of settings for C077 and C078.   No joy.

I am shooting in the dark here.  :)
