spent a lot of time this week with smartrise and magenetek trying to get rid of clunking noise on the stop and starts. For the stop, I had to enable ramp to stop paremeter which solved the noise when it stops but the noise when it takes off is still present. I kept telling smartrise we need to put juice to the motor as the brake lifts then enable the movement. I hate doing their R&D but it seems that's their game plan. So it ends up the engineers at smartrise have no way of adding pre-torque to a pm motor, Magenetek has a new software for the drive but they want an extra for it. I bought a package that was supposed to work but it doesn't and the customer is furious that they spent all this money and it sounds like Crap where the old PDQ control worked without everyone in the building hearing it.
