Hi
I need to help how to wire correctly the PNOZ x7 to my driver MR-J2S.

Thanks

or do i need to use PNOZ with my drivers
-
hi Hood
I think you can help me ?
this is my driver : http://www.automationsystemsandcontrols.net.au/PDF's%20Mitsubishi/Manuals/SERVO/MR-J2S-_A%20Instruction%20Manual.pdf
Thanks

Sorry have been snowed under with work the last while and have not been able to spend so much time here. I will try and have a look sometime later today if I get a chance.

Ok I assume you are wanting to connect in a similar manner to the diagram in the IP-A manual?
If yes then the Emergency Stop signal to your drive would be used. It requires a connection to 0v on your drives, ie break the connection and the drive E-Stops. To do that you would have SG (CN1B 10) one side of the relay contact on the PNOZ and the other side of the relay would be to EMG (CN1B 15)
See pic below.

hi hood
yes i do exactly that .... but when push the button ESTOP and after the ST1 ... my controllers stay in alarm ... how to activate normal mode .
-
You may need to use the drives Reset.

hi in your picture de fault from driver 1 .... where it go .... i have not ( input auxiliary alarm for the second driver )
-
If wanting to wre as CSMIO suggest then you would link the three fault signals from your drives and put them into the E-Stop circuit. That is assuming of course that the fault output from your drive is +24v when there is a fault and not _24v when there is no fault. If it is the latter then you would need to invert the signals vial relays or similar.

ok I recommend not using the PNOZ ?
-
Not sure what you are asking, or are you just stating your thoughts?
Hood
-
BTW my above post should have been +24v instead of _24v
Hood
-
if you see your picture with connection PNOZ .... only one wire from drivers go to Pnoz .... i my situation can i connect 4 faults in the same input of PNOZ
-
is that ok ? how i connect the faults outputs
-
Do your drives output 24v when there is a fault or do they remove the 24v output?
Hood

look the second picture when was the fault (ALM) it activate just a transistor
-
Ok, not the sharpest when it comes to electronics but it looks to me as if the output sinks. If that is the case then you could use the relay but it would have to be different. What you would have to do is have 24v going to the relays coil and the other side of the coil would connect to each of the fault outputs on your drive, you would then need to use the NC contact of the relay rather than the NO that you seem to be showing.
So what would happen is the coil is fed by 24v but it would not connect to 0v until one of the drives faulted. So in a Non-Fault position the 24v connected to the relays contacts would pass through the NC contact and onto the E-Stop string. If one drive faulted then the coil would get powered and the relays contact would open and thus the E-Stop string would be opened thus signalling an e-stop.

can put the parameter in CS-MIO that fault is activated as LOW .... and do that
-
i see in this picture we can connect many faults to the in CS-MIO-A ... i not see where i need to connect it on the port inputs 0-11 and how configure that ....if is 0 on input 1 ,2 or 3 ....all motors need to stop
-
You can wire things any way you wish and makes sense for you. The diagram CS-Lab has in the manual is just a way they suggest it can be done and I was thinking you were wishing to do it that way and thus I tailored my answers to that.
Below are two ways I do it with different drives and different machines using different safety relays.

Sorry was a bit pushed for time so didnt get a chance to fully respond.
If you look at the computurn PDF you will see I have two fault signals from my drives, the drives I use have configurable outputs, yours may be the same. Anyway you will note that I have one of these fault outputs from each drive going to an input on the IP-A, you can then configure the plugin to look at the Input and set it as a fault input. When this signal is seen the IP-A will halt everything and E-Stop the machine. I think that may be what you were asking?
This however, although good, is not 100% full proof as you are relying solely on software (csmio plugin) to halt things and that is why I also have a fault signal from each drive going to the safety relay to provide a hardware E-Stop in the event of a faulted drive.
