Empty car
must be at the bottom floor.
6.3.5 Setting start delay and P factor parameters to original values
6.4 Stopping (final rounding to the floor)
Step Action Note
1 Drive the elevator upwards a few times
in RDF mode (machine room inspection
drive mode in North America) from the
bottom floor.
Observe the movement of elevator
during the start.
Default value of
Start torque scaling
(6_27)
parameter is 1.00.
Always start to drive from the bottom
floor.
Wait 10 sec. between successive
drives:
the LWD signal may oscillate for
a while after stopping.
If there is roll back, decrease the value
of
Start torque scaling (6_27)
parameter in 0.05 increments.
Step Action Note
1Set Start delay (6_37) and P factor
(6_20)
parameters to original values.
Refer to the APPENDIX parameter list
779980.
2 Select
Save (6_99) parameter. 0 is blinking in the display.
Turn 0 to 1 and press ACCEPT. 0 turns steady.
3 Check that the correct value is recorded.
Step Action Note
1 For smoother and longer rounding
increase the value of
Final jerk
distance (6_32)
parameter.
If you want faster landing to the floor
level decrease the value.
Default value of
Final jerk distance
(6_32)
parameter is 125 mm.
Typical cases:
• If ADO is used, set long rounding
(125-200 mm).
• If no ADO, set short rounding (25-
100 mm).
