Technical Specifications and Nomenclature
To fully appreciate the utility of the device, one must first decode its nomenclature. The model number "CHE100-0R7G-S2" provides immediate insight into its capabilities. The "CHE100" designates the product series, indicating a chassis primarily designed for general-purpose applications. The segment "0R7" is the critical power rating identifier; in standard VFD coding, this denotes a rated power of 0.75 kW (approximately 1 Horsepower). This places the unit firmly in the category of low-power motor control, suitable for small pumps, fans, and conveyor systems.
The suffix "G" typically signifies that the drive is designed for "General Purpose" use, capable of handling variable torque loads (like fans) as well as constant torque loads. Finally, the "S2" denotes the specific product iteration or frame size, often indicating an updated hardware version with improved heat dissipation or electromagnetic compatibility. The device generally operates on a single-phase 220V input supply while delivering a three-phase output to the motor, a feature that makes it highly versatile for facilities lacking three-phase power infrastructure.
Functional Capabilities and Control
The core function of the INVT CHE100-0R7G-S2 is to convert fixed frequency and voltage input power into variable frequency and voltage output. By controlling the frequency of the electricity supplied to the motor, the drive can precisely regulate motor speed and torque. The manual for this unit outlines sophisticated control algorithms, most notably Vector Control (VC) and Voltage/Frequency (V/F) control. The V/F mode is the standard for simple applications like fans and pumps, where energy savings are prioritized. In contrast, the vector control mode offers higher precision, providing better torque response at low speeds, which is essential for more demanding industrial tasks.

Furthermore, the drive is equipped with a comprehensive suite of protection features. The manual details parameters for over-current protection, over-voltage protection, under-voltage protection, and over-heat protection. These safeguards are critical for extending the lifespan of both the motor and the drive itself, preventing catastrophic failures that can lead to costly downtime. The integration of a Programmable Logic Controller (PLC) logic within the drive parameters also allows for simple automation sequences to be executed without the need for an external controller.
User Interface and Usability
A significant aspect of the INVT CHE100-0R7G-S2 manual is its focus on the user interface. The unit typically features a detachable keypad with an LCD display or a series of LED indicators. This interface allows operators to monitor real-time data such as output frequency, current, voltage, and bus voltage. The parameter setup process, as described in the manual, is designed to be intuitive, often utilizing a modular structure where parameters are grouped by function (e.g., basic parameters, motor parameters, protection parameters). This ease of configuration lowers the barrier to entry for technicians, reducing the time required for commissioning and troubleshooting.
Industrial Applications and Conclusion
The practical applications of the INVT CHE100-0R7G-S2 are vast, particularly in industries requiring small-scale automation. It is ideally suited for HVAC systems, driving small exhaust fans or circulating pumps to optimize energy consumption based on demand. In manufacturing, it finds utility in material handling systems, such as small conveyor belts or packaging machinery, where precise speed control is necessary to synchronize production lines.

In conclusion, the INVT CHE100-0R7G-S2 is more than just a power converter; it is a critical tool for modernization and efficiency. By converting a standard 0.75 kW motor into a variable-speed system, it allows for significant energy savings and improved process control. The accompanying manual serves as a roadmap to unlocking these capabilities, guiding the user from basic installation to advanced parameter tuning. As industries continue to prioritize sustainability and precision, devices like the CHE100-0R7G-S2 will remain foundational elements in the architecture of automated systems.
After wiring, you must program basic parameters via the keypad. The manual lists these as mandatory:
| Parameter | Name | Recommended Value for 0.75kW Motor | | :--- | :--- | :--- | | P0-01 | Motor control mode | 0 (V/F control) or 1 (Sensorless vector) | | P0-03 | Max output frequency | 50.00 Hz (or 60.00 Hz for North America) | | P0-04 | Upper limit frequency | 50.00 Hz | | P1-00 | Motor rated power | 0.7 kW (or 0.75 kW depending on motor plate) | | P1-01 | Motor rated voltage | 220 V | | P1-02 | Motor rated current | Find value from motor nameplate (typical: 3.5–4.2A) | | P1-03 | Motor rated frequency | 50 Hz or 60 Hz | | P1-04 | Motor rated speed | e.g., 1420 RPM (for 4-pole 50 Hz) |
Crucial safety note from the manual: After changing P1-02 (motor current), perform a motor auto-tuning (P0-38 = 1 for static tuning) to optimize vector control.
The control terminal logic (PNP vs NPN) is explained in the manual. Connecting a PLC output incorrectly can damage the drive’s 24V internal supply.
