900M Series Variable Frequency Drive

Compared to general-purpose or high-performance vector inverters, the 900M Series Variable Frequency Drive offers significant advantages in space utilization and ease of use:

Extremely Compact, Space-Saving:The 900M Series Variable Frequency Drive features an extremely compact design, reducing its volume by more than 50% compared to general-purpose inverters of the same power. Its unique dimensions (such as the A00M specification) allow for easy installation in confined equipment control boxes, perfectly solving space-constrained problems.

Economical and Practical, High Cost-Effectiveness:Designed specifically for standard loads, it eliminates complex vector control algorithms (supporting only V/F control), meeting basic speed control requirements while offering a more competitive price, making it an economical alternative to traditional speed control methods.

Plug and Play, Extremely Simple Commissioning:Built-in simple PLC logic and abundant default parameters eliminate the need for cumbersome settings. Supports three-wire control (F1-06 parameter settings), perfectly adapting to various push-button switch operating habits; it's ready to run upon power-up.

Multi-pump circulation without sacrificing functionality: Despite its small size, it still features a built-in dual-pump automatic circulation function (F0-26=7), which can be directly used in small constant pressure water supply or circulation pump systems without the need to purchase an additional controller, saving money and space.

FAQ

Q1: What is the difference between the 900M series and the 900G series?

A: The 900M is a "mini economy" model, small in size and low in price, supporting only V/F control, suitable for low-power standard loads of 0.75KW-2.2KW; the 900G is a "general-purpose engineering" model, larger in size and more powerful, supporting vector control (SVC), with strong overload capacity, suitable for medium and high power and heavy-duty applications.

Q2: Can the 900M inverter power a submersible pump?

A: Yes. The 900M series has a built-in simple PID function. You only need to connect the pressure sensor signal to the AI terminal, set F0-01=6 (constant pressure water supply mode) and the relevant PID parameters (F5 group) to achieve constant pressure water supply control for the submersible pump.

Q3: Can the 900M panel be removed and installed on the cabinet door?

A: Removal is not recommended. The 900M series features a built-in mini panel design, connected to the main board via a ribbon cable, and is typically mounted on the top of the unit. For remote control, it is recommended to use an external potentiometer to adjust the frequency or to lead out control signals via a terminal cable.

Q4: Why is my 900M Series Variable Frequency Drive starting so slowly?

A: Please check the F0-04 (acceleration time) parameter. The default acceleration time of mini inverters may be relatively long. If the motor power is much greater than the load requirement, the acceleration time can be appropriately shortened (e.g., set to 2.0~5.0 seconds) to improve the starting response speed.

Q5: Does the 900M Series Variable Frequency Drive support communication control?

A: The standard 900M mini inverter typically does not come with an RS485 communication interface. If your application requires communication functionality, it is recommended to choose the 900G series general-purpose inverter, or confirm whether a special version with a communication card is required when purchasing.
