7.3.2 Comfort adjustment
Section 6.9 , Functional parameters Second row of F8-02～F8-04 primarily for regulating the
the comfort of non-weighing start， Gradually adjust base on F8-02=15.0%，F8-03=0.50，
F8-04=0.60 When adjusting
Gradually increase coefficient
of zero current servo（F8-02），until Slide down small and 1)
the motor not jitter after open the brake.
If the zero speed servo loop TI（F8-04）less than 1.00，If the motor; appear significant 2)
oscillation， Please increase the value of current coefficient of zero-servo (F8-02).
Zero speed servo loop KP (F8-03) can remain unchanged， Don’t tuned too lagre ， 3)
Otherwise may cause motor oscillation easily.
7.4 Power failure emergency running program instruction
When the lift is in use, if the system’s power suddenly broke, passengers may be trapped in
the car cage. In light of the situation, NICE 3000 integrated controller designed a power failure
emergency running (self-rescue running) program which is easy and convenient to fulfill.
NICE 3000 power failure emergency running program are separated into
three modes
according to the power source of the traction machine. They are auto-running car, 48V battery
power running, and UPS power running. To facilitate the description, explanation as follows:
Auto-running car: It means that opening the brake, and the prevent-force limits the car’s
running by permanent-magnet synchronous motor jumps out stator coil. That is a rescue-
way’s which the car is ru
nning slowly to get to the level. After the Nice 3000 receives a power-
failure-rescue signal, you should jump the U, V, W’s wire of permanent-magnet synchronous
motor, and open brake. The lift would auto-running. During the process you should monitor
the lift’s speed, till leveling. When the speed is slow, (The car is balance load or the load
variation’s number is small) you can close braking, and
stop operation.
48V battery supply of power to run: The main circuit of NICE3000 has adopted 48V battery
supply of power. The power of other part would adopt UPS supply which is greater than 220V.
Do it, the motor can run normally by store battery’s power, and the work power’s capacity
will be small. After NICE3000 chooses the way which is power failure rescue, it would run with
emergency speed (F
8-09). The direction is the same to the running direction of lift light-load.
Keep surveillance the speed of elevator in this period, and then output the passenger and stop
running.
UPS supply of power: Both the main circuit and work-power of Nice 3000 have adopted UPS
