A lot of companies do not want to go to the expense of purchasing a safety switch with a normally closed micro switch on motors controlled by drives. Wish the NEC would make it mandatory that at bare minimum when motor is not on the same floor as the drive then the motor must have a local lockable disconnect within 50' & visible from the motor. Would be ok to have disconnects say on water towers to be on the outside. We had 4 water towers with 60 HP motors where they only installed a 30 amp non fixed safety switch to LOTTO motors. I always walked hundreds of feet then climbed thru two door ways to install LOTTO on the drive disconnect.
