[Rs485 communication between PLC samba and VFD unitronics]

4 hours ago, kratmel said:

Some tips:

1) You must start to use UMI via blank project and configure 1 VFD.  

2) Configured Umi can be controled via simple UMI command (from UMI menu) and by changing speed and torqe variables defined in configuration.

3) Is it dip sw on RS485 comm card in correct = RS485 + termination?

4) Is it cable from UMI to RS485 card connected properly?

 

P.S.  I do not find any UMI inverters on din rail in Visilogic HW config of your project.

ADD UMI to project = add some hidden subroutine that is not visible for user.

You must try start to use UMI via project from example for configure 1 VFD.  

Greeatings , i dont use umi , i Have 3 vfds , and samba can only with 2 , 

Dip switch are 1 2 3 4 are on and the 5 6 OFF

I get cable form unitronics two wire one blue and it is on pin 1 and bluewhite it is pin 6 ,

1 pin +Rs485 on VFD

6pin -RS485 on VFD

 

have you any other solution

[Rs485 communication between PLC samba and VFD unitronics]

Can someone help , I cant make communication between Samba 70 j T20 with Rs485 communication card  and Unitronics VFDs ,

I want to make just control of speed and start stop of VFD, but cant make communication .

In attach is my code, can someone help .

Hi toreros,

First of all, have you already established a connexion between your PLC and the drive ?

To manipulate your drive parameters, you need to communicate with SDO or PDO functions within Visilogic.

Cheers,

Sideway.

Greeatings , this is problem can you tell me hovv , vvhich register i must read from servo ,for example if I need postion value on servo ??

Hi;

Have you tried :      Connection -- Communication-PC Settings

                                                6th Tab -  System Mode  -- Get  ?

                                                if it responds, then switch to Factory Boot and then try the OS Download again

 

                                             Also - V570's like to communicate at  115,200 Baud

Greeatings I have vision V280 and I have problem.

I do upload program and povver supply in this moment going off , in the middle , vvhen i povver on my vision i havnt anythin on screen , have you some solution ?

I have one problem vvith measuring temperature vvith pt100.

I use v1210 and expansion module pt400 , i have pt 100 vvith tvvo pt100 , problem is vvhen i start my inverter temperature value get some crazy value not good , vvhen motor is off

This post was started for a V120, which has limited features.  What family of PLC are you working with?

Joe T.

I vvork vvith vision 1210 , and I have expansion module like iodi16-to16.
On input I52 I 53 I have high speed input. on this input i vvire one pnp or npn sensor ,I have disk vvith 12 pulses per revolution ,
I need to calculate rpm and this information is feedback for PID.

The easiest way is to set in Hardware configuration I0 as high Speed counter. In the second line, you can define operand (MI) for frequency measurement. See relevant help topic for details.

In selected MI you will receive the number of pulses per second - Hz. Then, you need to multiply the this result by 60 to receive the number of pulses per minute. Then, you need to divide this result by the number of pulses your plate gives per revoluiton. The final reult will be in RPM (Revolutions per minute).

What is the expected range of results?

How many pulses gives your disk per revolution?

What is the presision needed?

Just note - Enhanced Vision models (for example V130) support special function Frequency measurements. It gives the frequency with resolution and precision of 0.01Hz.

greeatings . have you some examples , i need to measuring rpm its for me feedback for pid.

[long integer (32bits) and LCD]

Greeatings ,

 

I have one problem with u90 leader , I need to mul two number and result is bigger than 32k.

After mul this number i need to div , and that is problem i cant get right result.

Expmple :
MI0 = 1000
MI2= 53 

MI4=53000 that is ok ,
How can i divide MI4 now whit some number example 100 ???


Can someone help me ?

[PID how control SSR relay]

On 3/7/2020 at 6:40 AM, Joe Tauser said:

First, post the model and make of your SSR so we can truly know what you are using.  Most SSRs use a DC trigger signal of 3-30 VDC, which is why others keep recommending a transistor output to drive them. 

This is not totally necessary, it just works better.  You can certainly drive a typical SSR by switching a 24 VDC signal through a relay; you just have to slow it down with a longer cycle time on the PWM block.  Did you read my above post?

Joe T. 

Greeatings .

 

I use Fotek SSR-40 DA this relay have input 3-30VDC , i read all your post and i vvill try vvith pvvm like you say 

[PID how control SSR relay]

On 3/4/2020 at 12:31 AM, Ausman said:

Others have mentioned the issue, but I would be particularly careful trying to run an SSR with relays in a PWM.  The relays won't like it and you'll likely do damage if the stream is fast.  Even just for experimentation you may have a problem.

cheers, Aus

Have you some other solution ???

You'll use your PID to control the frequency or duty cycle.

You'll need "High-Speed" outputs. Those aren't available on the IO-D16A3-RO16.

I know, only digital TO have high speed , only try with examples of kratmel

Of course. Yes, PWM function blocks are available. Which PLC are you using?

Sounds like you're trying to create a thermostat. PID control makes no sense for digital I/O.

i cant belive they have module for Thermocouple but not module for controling ssr

Are you using the same computer for both VisiLogic and Remote Operator? If so, they would be using the exact same pathway and if one works, the other should too, but they both can't connect to the same port at the same time.

If not, then make sure the Remote Operator computer (or phone) is on the same subnet as the PLC. What I find is that my router hands out addresses to wired and wireless (wi-fi) with different subnets.

 

I have a new problem, I tried with another laptop, to try the remote operator, however the same problem is just that now I can't even load the program over Ethernet. I try with static ip but same problem , i try to change ip but same
