Internet PLC Forum

Hello,

To begin, I apologize in advance for my English language.

I need help to programming a stepper motor with controler nano10 then driver M880A.
I control this motor with  2 command buttons (backward / forward) By means of stepspeed and stepmove program.

I would like to add analog input control  for  modify motor  speed .
When i change the pps to DM

• in stepspeed (DM
• is my speed value in pps), an error message occurs:

 (Error:Illegal Pulse Rate for STEPMOVE!
   Program has been Halted!)

i' m a  recent  user of plc nano-10 and i-Trilogi i   would  like  to  find  someone  with  solutions to help me

Thanks.
