2. Stop the elevator at any oor, with the car in the no-load state. Set F8-00 to 0 and press
ENTER
.
3. Put N% load in the car. Then set F8-00 to N and press
ENTER
.
For example, if you put 500 kg load in the elevator with rated load of 1000 kg, set F8-00
to 50.
After the load-cell auto-tuning is completed, the corresponding no-load and full-load data
will be recorded in F8-06 and F8-07. You can also manually input the data according to the
actual situation.
Function Code Parameter Name Setting Range Default Unit Property
F8-01
Pre-torque selection
0: Invalid
1: Valid
0 - ★
It is used to set the pre-torque compensation mode at startup of the elevator.
When pre-torque compensation is used together with the load cell, the system outputs the
torque matching the load in advance to ensure the riding comfort at startup.
The output torque is limited by F2-08 (Torque upper limit). When the load torque is greater
than the set torque upper limit, the output torque of the system is the torque upper limit.

F8-02
Pre-torque offset 0.0–100.0
50.0 % ★
It is used to set the pre-torque offset. It is actually the balance coefcient of the elevator,
indicating the percentage of the car load to the rated load when the counterweight and the
car weight are balanced.
Function Code Parameter Name Setting Range Default Unit Property
F8-03
Drive gain 0.00–2.00
0.60 - ★
F8-04
Brake gain 0.00–2.00
0.60 - ★
These two parameters are used to set the pre-torque gain when the elevator runs on the
drive side or the brake side.
•
Motor driving state: full-load up, no-load down
•
Motor braking state: full-load down, no-load up
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 pre-torque compensation is
higher. The controller identies the braking or driving state according to the load cell signal
and automatically calculates the required torque compensation value.
When an analog device is used to measure the load, these parameters are used to adjust
the riding comfort at elevator startup. The method of adjusting the startup is as follows:
