PVED-CX Valve
« on: March 12, 2013, 08:52:41 AM »
Has Anyone an Idea, how to set up a can message to control one of these PVED-CX ( Can open ) Actuators?
A custome likes to use this kind of PVE, and i never had seen one of these.

Regards Gregor

Hi Gregor.

I have used the CX, they go well.
Search for the technical document 11070179 in the Sauer Danfoss website.

Hello,

I have got the PVED-CX on my table (there are 4 sections with CAN),
I konw ID's: 16, 17, 18, 19 (in hex 10, 11, 12, 13)

All the sections shine on orange which mean critical fault.
I think that there is a command to run them but i do not know what command.

I think that frame sending on CAN should look like this:
610 xx xx xx xx xx xx xx xx   - command for ID=16
611 xx xx xx xx xx xx xx xx   - command for ID=17
...

Does enyone know how to fix it?

Hi Andrzey13.

The orange LED reports 2 states.
10 Hz
Module has found fault on neighbor and has reported error code 0x8309, 0x830A
or 0x8308. Neighbor reporting by LED has precedence over self reporting by LED.
This is also happening by missing neighbor.
Orange 1 Hz
Initialization of EEPROM after firmware download has ended.
If the initialization process was not finalized before power off the process will
restart at next boot up and then blink by finalization.


You should see a boot up message from the PVED-CX's on power up as Id710,711,712,713 etc.
They also report their error states, suggest you connect via CANking and view the situation, example below.

Hi Neil,

Thanks for fast answer.

That is correct what you wrote about blinking orange LED.

In my case there is still shining orange LED, which means fault critical or severe (on page 37 in manual)

As I red the manual, I think that my commands transmite on CAN should look like this:

(page 56 in manual)

000 2 01 10
610 8 22 40 60 00 09 00 00 00    - cyklic 20ms
610 8 22 40 60 00 0B 00 00 00    - cyklic 20ms
610 8 22 42 60 00 01 00 00 00    - cyklic 20ms
610 8 22 40 60 00 0F 00 00 00    - cyklic 20ms

then

000 2 01 00
310 3 09 00 01    - cyklic 10ms
310 3 0B 00 01    - cyklic 10ms
310 3 0F 00 01    - cyklic 10ms

then (page 57 in manual)

210 8  00 00 00 00 00 00 00 00 
080 0

Will you agree with me, Neil?
I will check this for few hours and write what happen.

It looks to be working - I have got green LED's.

But now, is it possible to not send these commands all the time after power off/on?
And what command use to set position of spool - for example I want to maximum flow oil by one section using CAN command.

Below is solution of my problems.

These are commands to run the valve PVED-CX

710 1 00
000 2 01 00
080 0                                                   - cyclic 10ms
310 3 09 00 01
310 3 0B 00 01
310 3 0F 00 01

210 8 7F 00 00 00 00 00 00 00               - cyclic 10ms (7F means that spool of first sectio is opend to maximum)
