Re: Determine Motor's Ability to Hold Load
We use an FP on our elevator from 2008, and had a similar problem, even with the Victors in brake mode - you get to the top and set it to 0, and it would slowly drift down. There are really two ways to fix a problem like this - implement a mechanical brake (which we'll probably be doing this year), or stall the motor intentionally. In 2008, we ended up stalling the motor. By telling it to go forward very slow, the elevator would perfectly hold position. While we didn't have any problems with the motor that year, it always worried us that it would burn out. Maybe we were lucky... we only had the elevator stalled for a few seconds at a time.
