New ethercat / probe basic control for minimonster

There is no documentation of registers?
Almost impossible without. 

As I keep poking, I'm finding there are registers now at 8192 range, but they cant be written? 8192 has a value of 6. 8191/ 8193 etc at 0.

Hm

no documentation at all sadly

so we have 8192 to 8203. all 0 except 8192 which is 6, and seems not writable. others seem writable but do not induce any change.

i have an idea: i will turn the drive back to panel frequency and run control and see if i can see anything change

ding ding. so 8192 IS run/stop. goes from 6 to 1. which is true/false im almost positive.

But i don't have a way to write it. every write command says illegal data or address or function (different ones give different errors).

Do i need to tell it it is a true/false register, and not an int/float? if yes, how? i do not see any syntax for that.

thanks for all the help so far, i feel like were getting close, AND i also understand things better.

ok, sooo

function 3 reads a float and int (6 or 1)
function 1 reads a bit (true/false)
function 5 says illegal function (write coil)
function 6 says illegal data type

What is next to try? I rechecked the vfd settings, and its all "right". Also found out the params are registers (f0.04 = 0Xf004) so that neat. Not actually helpful though.

Do you have a link to the manual?
Maybe there is something helpful in there.

the manual is for a "slightly different" has no modbus information. my drive is called an HSD7000 and is a nearly identical clone of the innovance, but has modbus built in instead of on an add in card.
md380-inovance-manual.pdf

The add in card manual i am not sure is relevant
Communication Example; Configuration Of Rs485 Communication Between Drive And H5U - Inovance MD38TX1 Series User Manual [Page 50] | ManualsLib

 

aha!
looked at that add in card and realised something. it is an int with multiple settings (start, reverse stop, etc). but when the pin initialises it writes a 0, which is not allowed.

so i ignore that and in halshow make it 1 and it turns on. and 6 turns it off.
So now that all makes sense!

The next thing i see is frequency is not 2001, its 1000 (4096 in decimal).

So a quick test of that and we get... motion!

(except its going reverse which is a setting i can change)

woooohooooo

so now, we need a hal and then a spindle section in the ini? because i am using ethercat from scratch here, i have literally no other functions in my main HAL or INI.

What should i be expecting to add there?

Thanks!

Should add that the frequency seems to be a percent x 100. so setting it to 100 gives me 13.33 hz which is 1% of full speed.

Gonna need to work that into my math.
