[QUOTE="dreambox1959, post: 1138725, member: 314801"] I use a mount of my own making (very solid) where the operating clearance is almost non-existent! But above all I have a counterweight which makes that the effort is the same all along the travel. I wanted to speed up the movements, on my installation I supply the actuator with 48V instead of 36V (a vbox gave 28V) it works since at least 4 years. But the motor was not stopping fast enough and fine tuning was difficult! I added a PWM card where I have a progressive acceleration over 2 seconds and a slowdown according to the number of pulses that separate me from the finish. I added another little thing: I start at a very low fixed speed for 1 second then I accelerate, it allows to optimize the position. At the deceleration I have no problems, it's only at the start that I must not decrease the speed too much, I have planned to make this parameter adjustable by the user. [/QUOTE]
