I have a key call Start, stop which start and stop the power unit. I have a drive who control the electric motor speed
with a 0-10V signal. So when I push the Key Start, the electric motor start to ramp up to 600 RPM. I have two other keys that can increase or decrease the electric motor speed(minimum speed is always 600 and max is 2200). Let say I increase speed to 55% and I turn off the electric motor with the Stop key. The 55% setting still
stay there if I start again the electric motor. I want when I stop the motor that those settings values return to zero. I think I have to do a ‘state machine’ to reset all values to zero but I don’t know how to do exactly and where to put it?

Thank you.

Hello mikwin,

How do you increase or derease the speed of the electric motor? Do you change the value of a variable?

You could create a calculation event for that variable to change its value to zero. Then you could create an event that executes the calculation event and the event to stop the engine. This event would be the one you fire from the key press.
