2) Adjustment to elevator startup
a. Adjustment for no-load-cell startup
The parameter setting related to riding comfort adjustment for no-load-cell startup is described
in the following table.
Parameter
No.
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
3: Both load cell and automatic
pre-torque compensation effective

The no-load-cell
startup function is
enabled when F8-01
is set to 2.
F2-11
Position lock
current coefcient
0.20%–50.0% 15%
These are position
lock parameters, and
are valid only when
F8-01 is 2.
F2-12
Position lock
speed loop Kp
0.00–2.00 0.5
F2-13
Position lock
speed loop Ki
0.00–2.00 0.6
When no-load-cell pre-torque compensation is used (F8-01 = 2), no analog load cell is required,
and the controller quickly compensates the torque based on slight rotation change of the
encoder at startup.
The default setting of F2-11 to F2-13 is proper for most large-power motors, and you need
not modify these parameters. For the small-power motor (P ≤ 5.5 kW), the motor may have
oscillation or noise at with-load startup, and passengers in the car may have a strong feeling of
car lurch. To eliminate 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.
Parameter
No.
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
3: Both load cell and automatic
pre-torque compensation effective

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:
