Hello,

I program currently the LOGO and i have a problem to find an output to generate a pulse at frequency upper than the function "pulse asynchrone generator" who's don't have down then 0,01 sec (100 Hz);

It's necessary for a microstep drive;

Have you another function or a module to add at the LOGO?

Thank you for the help

Hello,

Thank you for your answer;

Do you know if exist a reliable module to generate these pulse ?

Best regards

Freddy

Hi,

you can create a pulse generator with ladder logic in the logo. Use one TON and one TOF timer

--[ ]----TON-----( )

--[/]----TOF------( )

The NO contact and the TOF coil would be Bit 0.1

The NC contact and the TON coil would be Bit 0.0

Set both your timers to same time value.

Cheers
