car lurch, do as follows:
● Decrease the value of F2-11 (between 5 and 15) to eliminate motor oscillation.
● Decrease the values of F2-12 and F2-13 (between 0.1 and 0.8) to reduce the motor noise and
improve riding comfort at startup.
b. Adjustment for load cell startup
The parameter setting related to riding comfort adjustment for load cell startup is described in the
following table.
Function Code Parameter Name Setting Range Default Remarks
F8-01
Pre-torque
selection
0: Pre-torque invalid
1: Load cell pre-torque compensation
2: Automatic pre-torque compensation
0
When a load cell is
used, set F8-01 to 1.
F8-02 Pre-torque offset 0.0%–100.0% 50.0%
These are pre-
torque regulating
parameters.
F8-03 Drive gain 0.00–2.00 0.60
F8-04 Brake gain 0.00–2.00 0.60
When an analog load cell is used (F8-01 = 1 in this case), the controller identies the braking or
driving state according to the load cell signal and automatically calculates the required torque
compensation value. F8-03 and F8-04 are used to adjust elevator startup when the analog load cell
is used. The method of adjusting the two parameters are as follows:
● In the driving state, increase F8-03 properly if there is rollback at elevator startup, and decrease
F8-03 if there is car lurch at elevator startup.
● In the braking state, increase F8-04 properly if there is jerk in command direction at elevator
startup, and decrease F8-04 if there is car lurch at elevator startup.
More details about these parameters are as follows:
● F8-02 (Pre-torque offset) is actually the elevator balance coefcient, namely, the percentage
of the car load to the rated load when the car and counterweight are balanced. This parameter
must be set correctly.
● F8-03 (Drive gain) or F8-04 (Brake gain) scales the elevator’s present pre-torque coefcient
when the motor runs at the drive or brake side. If the gain set is higher, then the calculated
value of startup pro-torque compensation is higher.
● The motor’s driving state and braking state are dened as follows:
Motor driving state: full-load up, no-load down
Motor braking state: full-load down, no-load up
3) Handling of rollback at elevator startup and stop
The parameter setting related to rollback at elevator startup and stop is described in the following
table.
Function Code Parameter Name Setting Range Default
F3-19 Brake release delay 0.000–2.000s 0.600s
