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.

Something wrong with the drive settings concerning the motor?

Try altering the accel/decel parameters.
Also could be tacho issue as lift vibrates all up shaft!
Infact id be quite confident to head towards tacho first.

I would check cables to be sure they are not twisting in sheave. Kone cables have no hemp core, sheaves have no liners, and installers never check tension
