| High Performance Vector Control Inverter (CHV Series) |
| |
 |
Features and applications:
1) Power range: 1.5 ~ 315kW (3AC 380V±15%)
2) Output frequency: 0 ~ 600Hz
3) Control mode: vector control without PG, vector control with PG, V/F
control
4) Overload capacity: 150% rated current 60s; 180% rated current 10s
5) Speed control accuracy: ±0.5% of max. speed (SVC); ±0.02% of max.
speed (VC)
6) Starting torque: 150% / 0.5Hz (SVC); 180% / 0Hz (VC)
7) High torque at low speed, powerful overload capability and fast dynamic
response: wide application in such industries as injection molding
machines, lift, crane, textile, pulp and paper and steel metallurgy
8) Automatic carrier frequency adjustment: automatic carrier frequency
adjustment according to the temperature and load features to ensure
mute operation
9) Fast acceleration (deceleration) time (minimum 0.1s): meets the
requirement for fast brake and accurate positioning, applicable to
bag-making machines and high-speed forming machines
10) Common DC bus solution: a common rectifier unit or rectifier feedback
unit feed energy to several inverters through DC bus. The energy
generated upon motor brake can implement automatic balance through
the DC bus, and supply power for the motor. Thus, the electric energy
absorbed from the power grid can be reduced. The system is
energy-saving, which is applicable to such industries as paper-making,
chemical fiber production line and cranes
11) Closed loop torque control: a PG card (optional) is used to detect the
rotation speed of the motor to implement closed loop torque control so
that the output torque of the inverter can be adjusted instantly in real time
with the load change
12) Fixed length control: the length is calculated according to the digital
input or the high speed pulse signal input
13) Frequency droop: if multiple inverters drive the same load, different
speeds may cause unbalanced load allocation, so that the inverter with
higher speed will bear heavier load
14) External LCD panel: the system can display four lines in Chinese to
facilitate operations of Chinese users, and meanwhile it supports the
parameter copy function
15) Unique shortcut menu button: provides fast functional parameter viewing
and modification method
16) Constant tension control: the built-in roll diameter calculation of the
tension control card (option) can implement winding (unwinding) control
and direct (indirect) tension control
17) Constant pressure water supply control: a water supply control card
(option) can implement such functions as closed loop of water supply
pressure, circulated switching of pumps, dormancy and timing water supply
to ensure average operation time of the water pumps and prolong the
service life. The system has found wide application in waterworks, water
supply in communities, heat supply stations and central air conditioning
