any response to hall calls. After the door is automatically closed and the elevator
buzzes for 30s, the system forcedly starts a braking force test.

F8-00 Load for load cell auto-tuning 0 to 100 0 %
★
To perform load cell auto-tuning, do as follows:
Step 1: Ensure that F8-01 is set to 0 and F5-36 (Load cell input selection) is set to 2 (CTB
analog input) or 3 (MCB analog input) to make the system allow load cell auto tuning.
and press
.
Step 3: Put N% load in the car. Then set F8-00 to N and press
. 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.

F8-01 is used to set the pre-torque compensation mode at startup of the elevator. The
values are as follows:
■
0: Pre-torque invalid
Load cell auto-tuning is allowed.
■
1: Load cell pre-torque compensation
With a load cell, the system implements the pre-torque compensation function.
■
2: Automatic pre-torque compensation
The system automatically adjusts the compensated torque at startup without a
load cell.
■
3: Both load cell pre-torque compensation and automatic pre-torque compensation
valid
When automatically adjusting the startup compensation torque, the system make
occasions. If F8-01 is set to 1, 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.
