Mr Supreme stranger Joined: Nov 2012 Posts: 2	I have a Kone Minispace with a V3F25 drive with a overhead motor and machine room. The Elevator vibrates strongly when lift decelerates/accelerates about two seconds before brakes are applied/released. At full speed the car vibrates verry lightly almost unnoticed by passengers. I am thinking of checking the motor tac and brakes. Please advise. Top Reply Quote Quick Reply Quick Quote Notify Email Post Previous Topic Index Next Topic
