CHV190 series special inverter for crane
- 183 -
torque balance of two motors distribution and speed synchronization of two lifting
mechanism.
(2) Horizontal movement mechanism
Horizontal movement mechanisms of cranes are classified to cart agency with big motor
or small motor. Carts agencies use multi-motors drive scheme. As rotation inertia of crane
horizontal movement mechanism is large, motor acceleration need larger starting torque,
motor shaft output power PM of crane horizontal movement mechanism is composed of
load power Pj and acceleration power Pa.
PM ≥ Pj + Pa
As horizontal movement mechanism adopts one CHV190 inverter driving more than one
motor, inverter capacity selection should follow formula as below.
ICN ≥ kIM
I
CN
≥ kI
M
k - Current waveform correction factor (k=1.05-1.1 when PWM modulation mode)
I
CN
- Inverter rated output current, A
I
M
- Motor rated current of frequency power, A
n – Motor number of inverter drived
C.2 Renewable Energy Treatment
The lifting and horizontal movement mechanism drive potential load running down or
horizontally as emergency deceleration or downwind. Then motor works in regenerative
state. Inverter transfer mechanical energy to electrical energy and feed back to DC circuit.
The voltage of capacity of DC bus rose. If no necessary measures, when the voltage rises
to protection limit and trip over voltage.
There are two schemes to deal with continuous renewable energy in high-performance
engineering inverter.
① Dissipate the energy by resistor connecting to DC circuit
This way is called dynamic brake;
② Use renewable rectifier way to return regenerative energy to mains. This way is called
regenerative braking.
Please refer to DBU and RBU manual for specific parameters and instructions.
C.2.1 Dynamic braking
Dynamic brake is composed of braking unit and braking resistor. Dynamic brake ability
depends on permitted power of braking resistor. Renewable power PM must meet the
condition, PM <PR (PR is permitted power of braking resistor). If PM>PR, it is necessary
