ZFeng 900 Series 5.5Kw-T General Vector Variable Frequency Drive ZF900 is a new generation main model independently developed by
ZFeng, which can adjust the speed of synchronous or asynchronous
motors and has a wide power range of 5.5KW~800KW. While maintaining
excellent basic performance and functionality, the product has
significantly improved usability, maintainability, reduced
installation space, and higher design standards from the user's
perspective. It adopts a high standard design in the industry,
based on years of accumulated experience in multiple industries and
persistent pursuit and leadership of drive technology. With
high-performance current vector technology, induction motors can be
easily driven to meet the working requirements in various
environments. Function characteristics- Multi interface mode:5 digital input terminals, one of which
supports high-speed pulse input up to 100kHz; 2 analog input
terminals, 1 only supports 0~10V voltage input, and 1 supports
0~10V voltage input or 0~20mA current input; Expandable with 8
digital input terminals;
- Built in sensor auxiliary power supply: 10V, 24V auxiliary standard
power supply, convenient for the needs of sensors with different
voltage levels.
- Supports multiple PG cards: Supports various encoder interfaces
such as collector signal,splitter signal and rotary signal, easy to
achieve closed-loop vector control.
- Independent air duct design: Adopting an independent air duct
design can effectively prevent dust from entering the interior of
the frequency converter and which can cause the faults such as
short circuits, improving the reliability of the product; Choose a
cooling fan with long lifespan and high air volume to effectively
reduce the temperature rise of the frequency converter and ensure
its reliable and stable operation.
Application Covering industrial scenarios that require precise control of motor
speed and torque: - Traditional industries: fans, water pumps, compressors, conveyor
belts (energy-saving and consumption reducing), metallurgical
rolling mills (high-precision control).
- Specialized equipment: CNC machine tools (tool feed control),
textile machinery (yarn winding stability), woodworking machinery
(cutting and polishing process optimization).
- Emerging fields: New energy vehicle drive motors (torque dynamic
regulation), photovoltaic inverters (improvement of new energy grid
connection efficiency).
Key parameters for selection- Power matching: It is recommended that the power of the frequency
converter be 1.1-1.5 times the rated power of the motor, with an
overload margin reserved.
- Load characteristics: Constant torque loads (such as cranes)
require low-frequency high torque output, while variable torque
loads (such as fans) focus on energy conservation.
- Environmental adaptability: Ex d/Ex e certified models are required
for explosion-proof scenarios, and IP55 or above protection level
is required for humid environments.
