Delta Plc Solenoid Pulse

4 posts in this topic

Hi there,

I'm working on a project on a cupcake machine. I have to throw empty wrappers so I'm using a photoelectric sensor to sense the empty cupcake and after 2.5-sec air solenoid activated with delta PLC to throw that empty wrapper.

The thing which I want to discuss here is that I want to operate my solenoid with pulse means when the empty wrapper comes to the solenoid through the conveyor then the solenoid gives a pulse of air so the upcoming filled wrapped will not disturb with this air.

how Should I program my delta plc it is a transistor base. Can I use PWM?

Best Regards,

Asad Raza

Use a timer in your program so that once you detect and empty, you set the output on and then turn it off after some time delay.  You will need to determine how long that time is.

PWM is typically for stepper motors, not for on/off control.

Not familiar with Delta PLC, but did similar with an Omron decades ago.

hi Crossbow,

I hope you are doing well. I had used timer before and it is working but I want to give a pulse to my solenoid with Plc. So my upcoming filled packets will not disturb.

@asad110 I'm not a Delta programmer, but I think @Crossbow was meaning use what starts the timer to latch the output on and use the end of the timer to unlatch the output.
