4) The motor wiring must be correct (UVW cables of the motor are connected respectively to
UVW terminals of the controller). If the motor wiring is incorrect in the with-load auto-tuning
mode, the motor may jitter or may fail to run and report Err20 (subcode 3). To solve the
problem, replace any two of motor UVW cables.

Output State of RUN and Brake Contactors
For the sake of safety in different control modes, the system handles the output commands
to the RUN contactor or brake contactor differently. In some situations, it is necessary to
release the RUN contactor or the brake contactor manually.
The following table lists the output state of the running and brake contactors.

5.1.3 Trial Running at Normal Speed
After ensuring that running at inspection speed is normal, perform shaft auto-tuning, and
then you can perform trial running at normal speed (the elevator satises the safety running
requirements).
To perform shaft auto-tuning, the following conditions must be satised:
1. The signals of the encoder and leveling sensors (NC, NO) are correct and the slow-
down switches are installed properly and act correctly.
2. When the elevator is at the bottom oor, the down slow-down 1 switch acts.
3. The elevator is in the inspection state. The control mode is distance control and CLVC
(F0-00 = 1, F0-01 = 1).
4. The top oor number (F6-00) and bottom oor number (F6-01) are set correctly.
5. The system is not in the fault alarm state. If there is a fault at the moment, press
For shaft auto-tuning when there are only two oors, the elevator needs to run to below the bottom
leveling position, that is, the leveling sensor is disconnected from the leveling plate. There is no
such requirement when there are multiple oors.
