    Hi all,

    I would like to replace the spindles on my SCN5 actuators as they are worn together with the spindle nuts. The original spindle is a trapezoidal spindle with a diameter of 8 mm and a pitch of 6 mm per turn. I would like to install a 10 mm spindle with a 3 mm pitch. This would give me a speed of only 200 mm/s instead of 400 mm/s, which corresponds to the SCN6 actuators. These actuators are also used for seatmovers, but the SCN5 would then have twice the power for the movement.
    Now, of course, the question is whether something needs to be reconfigured on the SCN5 itself, or whether the electronics themselves will notice during initialisation that twice the number of turns is now required for x mm of travel and the same for acceleration. Does anyone know whether the controller recognises a changed spindle ratio by itself or whether adjustments need to be made to the controller? Perhaps someone has already done something like this and can report on their experiences?

    Thanks in advance.
