Figure 9.2 Flowchart for elevator starting without load compensation
b) Parameters: Parameters related to function can be seen below in table below.
Chart 9.1 Elevator start without load compensation parameters list
c) Adjustment method:
Main parameters used are FA-08, FA-09 and FA-11.
FA-09: This parameter is the working time for starting without load compensation after
brake opens, it must be set according to the actual brake opening time, if the time is too
short, elevator will slip as this action will be over before brake fully opened; Also the
value of F2-00 (brake opening time before running) must be 100ms longer than the value
of FA-09, so that this action can finish before speed curve start.
FA-08 and FA-11:Two gain parameters for the starting without load compensation action,
these two parameters can be adjusted according to the elevator slipping condition and
comfort level, if the slipping is too much please increase the value of FA-08; if the traction
machine gets vibration, please reduce this value; during the period of torque keeping, if
there is slight slipping or small back-and-forth movement on traction sheave, please
increase the value of FA-11, if there is vibration, please reduce this value.
(The period of torque keeping means keep zero-speed period before speed curve start,
after release brake.)
Note:
1) During commissioning, besides the mentioned 3 parameters, other parameters in FA
group can be kept with factory setting.
2) The setting value of above parameters is just for reference, as the PG card is not same
in different job side; please adjust above parameters based on site condition.
3) F9-00 is the pre-set torque when the starting without load compensation function is
enabled. Generally, there is no need to change its value, please keep it with factory
setting (0).
