2. Check that the conditions for shaft auto-tuning have been met.
● The elevator is in the inspection state.
● The elevator is at the leveling position of the bottom oor.
● The down slow-down switch 1 signal input to the MCB is active.
● The NICE3000

is not in the fault state. If there is a fault, press
to reset the fault.
When there are only two oors, the elevator needs to run to below the bottom leveling position, that
is, at least one leveling sensor is below the leveling plate. This is the prerequisite for successful
shaft auto-tuning.
3. Perform shaft auto-tuning.
When the preceding conditions are met, start shaft auto-tuning by using any of the following
methods:
● Set F1-11 to 3 on the operation panel.
● Set F7 to 1 on the keypad of the MCB.
After shaft auto-tuning starts, the elevator runs at the inspection speed set in F3-11 and stops after
reaching the leveling plate of the top oor. Then, the keypad on the MCB displays the present oor
number (top oor), indicating that shaft auto-tuning is successful.
If fault E35 is reported during the process, it indicates that shaft auto-tuning fails. You need to rectify
the fault according to the solution described in Chapter 9, and perform shaft auto-tuning again.
4. Perform running test at normal speed.
After shaft auto-tuning is completed successfully, running at normal speed may not be successful
because the door controller and full-load/overload function are not commissioned. You can set
parameters to enable the system to forbid door open and allow overload, and then perform running
test at normal speed.
● Set F7-05 (Door open forbidden) to 1 (Yes).
● Set F7-06 (Overload function) to 1 (Enabled).
● Turn the inspection switch to the "Normal" state.
● Set F7-00 (Car call oor registered) to register a oor call and test the running at normal speed.
The call set in F7-00 is the same as car call inside the elevator. Set F7-00 to any oor number,
and run the elevator at normal speed; check whether the motor, elevator, and controller are
abnormal during the running.
It is recommended that you set F0-03 (Maximum running speed) to a small value for initial
tests; after several times of tests are successful, set F0-03 to the required value.
● After the test is completed, restore all parameters in group F7 to 0.
The controller restores F7-00 to F7-02 and F7-05 to F7-07 to 0 after power-on again. If you need to
continue the test, set these parameters again.
