Frequency Inverter
PRODUCT DESCRIPTION
22kw 30hp variable frequency drive VFD AC DRIVE INVERTERS vector
control
Product Advantage
1. Optimized external installation and internal structure and
independent air flue design, fully enclosed electrical space
design.
2. Output automatic voltage regulation function (AVR),
automatically adjust the output pulse width to eliminate the
influence of the grid change on load.
3. Built-in PID regulation function to facilitate the realization
of closed loop control of the temperature, pressure and flow, and
reduce the cost of the control system.
4. Standard MODBUS communication protocol. Easy to achieve the
communication between PLC, IPC and other industrial equipments.
Advantages
Thanks to sophisticated engineers, scientific producing
workmanship, rigorous quality control systems and management team,
K-Drive frequency inverters are equipped with advanced features,
some of which are listed as below:
01. Starting torque: 180% at 0.5Hz (V/f pattern, SVC pattern);
02. Speed adjustable range: 1: 100 (V/f pattern, SVC pattern);
03. Speed accuracy: +/-0.5% (V/f pattern), +/-0.2% (SVC pattern);
04. Over load capability: 150% 1minute, 180% 10seconds;
05. Abundant frequency command sources;
06. Diverse input and output terminals;
07. Ambient temperature: -10°C~50°C;
08. High precise torque constraint, process PID control, multi-speed
control, contracting brake control, field weakening control, all
sides protection, etc;
09. Online and offline auto-tuning of motor parameters can both
performed;
10. Extremely short-time acceleration can be performed without any
trip, such as 0.1s or 0s from 0Hz to 50Hz;
