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 Ognyan Obretenov

Sure, here is it PTO.vlp

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 Ognyan Obretenov

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.

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.

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?

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

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

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

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.

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 pic_15_2.bmp code.bmp

Hi , I am looking for interrupt routine called periodically. Is there such in UniLogic?

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

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, Ognyan Obretenov
