Hi guys,
I would like to ask some help from the expert here about my problem. Acually, it's just a follow up question on my previous post. I want to control a motor with an analog voltage output 0 t0 10vdc supplied to the amplifier. I have a digital rotary switch with 0 to 15 positions. My digital to analog scaling is 0-4000 vs 0-10vdc. I already tried it and my problem is the acceleration and deceleration so abrupt whenever I turn my rotary switch abruptly from low to high speed and from high to low speed. Somebody advice me to use timer for acceleration and deceleration. My idea is to use also the timer value to add or subtract from my digital value 0-4000 stored in data register to be converted to analog value. But I could hardly translate my math into ladder logic in this situation. Can anyone give me an additional idea on how to do it? By the way, I'm using mitsi A1SHcpu with A1s62da
Thank you and advance.
