[problem with 0808THS target mode]

I have a project with 2pcs of 0808THS, every Block1 is configured as PWM, 1 channel , with target.

when I set 

PWM Frequency = 50000

PWM Duty cycle channel1 =500

PWM mode = 0

PWM Enable =1 

my stepper moves but PWM Current Position is 0 all the time

if i set 

PWM Frequency = 50000

PWM Duty cycle channel1 =500

PWM mode = 1

PWM Target = 100000

PWM Target Enable=1

my stepper moves , PWM Target reached is get 1 afeter some time , but again  PWM Current Position is 0 all the time 

 

so my problem is "PWM Current Position" -  what i did wrong and why PWM Current Position is not count pulses?

 

Any ideas?

Thank you

[V430 TR34 problem with PTO - big delay on start and stop]

Hi everyone

I need some help/ideas- i have project with V430-TR34 using PTO to control one stepper motor. I did the function according to example and all works. I have JOG moves and  moves to position.

The only problem i have is that when I press Jog button the motor starts t move with big delay about 2 sec . I try to addjust the Acc/Dec time , but delay is the same.

I tried to save the results in the table and i see that after max 100ms after Jog button the speed of PTO is as needed, but the motor has delay.

 

Any ideas what to change/adjust. I am short of ideas - Almost a week I am struggling with this problem      

 

Thank you in advance

[V430-J-TRA22 HSO Step Control]

The questions is : is it possible the PLC to stop itself when the current position reach the target position?

of course if I turn run bit off the motor will stop.

[V430-J-TRA22 HSO Step Control]

Hi

Thank you for the replay

 

I know about the PTO- my  problem with PTO is that I cannot change the speed during move.

If I use HSO(step control) I can set target position, can know the current position and can change the speed. The question is is it possible to stop when reach target position. 

 

[V430-J-TRA22 HSO Step Control]

Hi 

I use V430-J-tra22 for step control. I would like to set target position and when current position reach target HSO to stop. 

Is it possible?  

Now I see that current position reach target and reset to 0 and continue to move. 

 

Any Ideas?

[Problem with analog output]

Yes - I have sent - and yesterday  I have received msg that they found that there is a problem with WCB1. 

[Problem with analog output]

I had ask support  before to write here , but too slow response

[Problem with analog output]

Hi thank you for the replay.

By the way we have checked with UIA-0402N and it works perfect

may be the problem is hardware issue with UIS-WCB1

 

[Problem with analog output]

Hi everyone

 

I need urgent HELP.

Has anyone tried to write to  analog output  every 50ms values and has he received good signal from analog output?

I have tried the simple project from picture (code.bmp) and received very bad results.

 

 

 

 

 

 

[Problem with analog output]

Hi  everyone

I have very strange problem 

We are trying to change the analog output like that in loop: 50milisec value1 and 50milisec value2

But we have not good result

 I have use USP-07-B10 and UIS-WCB1

 

I attach the picture of the code and the scope of result I got.

Thank you for any Ideas

Thank you

I will try

Thank you.

Can you advice me : Is there any easy way to redesign/change  the project to remove/disable the UserAccessControl ?

I need the same project but when I install on one device to have UserAccessControl and next time when install on another device without UserAccessControl

 

["User Access Control" auto login or login from ladder]

Hi,
I have a project (HMI USP-070-B10) with several users and groups. Using 3 access levels into the screen controls. I have a client who would like to have full access without login every time when power on the HMI.
Is it possible  to make something like auto login or to make default user with full access?

Thank you in advance,

[Need help to connect Unistream to ex-rc1]

Hi everyone

I have HMI USP-070-B10 and need to connect to EX-RC1

I have done all in my project according to manuals but not transfer

Than I have loaded example EX-RC1_IO to Unistream and to EX-rc1 and again no transfer

 

I see that the HMI sends data and Alive data , but receive nothing

The same in EX-rc1 - send data and alive , but receive nothing

I have checked the wiring and power suply - all is ok

any idea where is the problem
