moment when the system sends the brake release command; this is to prevent rollback. If there
is obvious rollback at elevator startup, increase F3-19 properly.
The system retains the zero-speed torque current output within the time set in F8-11 from the
moment when the system sends the brake apply command; this is to prevent rollback. If there is
obvious rollback at elevator startup, increase F8-11 properly.
4) Handling of current noise at motor startup and stop
During elevator startup or stop, certain motors may generate noise when the current is applied
before the brake is released or the current is removed after the brake is applied. To reduce
motor noise, increase F2-16 or F2-17 properly.

Bad riding comfort due to static friction may often exist in villa elevators. When there is large
friction between the guide shoes and the guide rails, large static friction generates at the
moment of startup, leading to bad riding comfort. Make the system starts up at the specied
speed by setting these parameters to eliminate friction and improve riding comfort.
