OC1 / OC2 / OC3 (Overcurrent): Check for a motor short circuit, heavy mechanical load, or if the acceleration time (P0.11) is too short.OV1 / OV2 / OV3 (Overvoltage): Often occurs during rapid deceleration. Increase deceleration time (P0.12) or install a braking resistor.UV (Undervoltage): Check the input power supply for stability or a loose connection.OL1 / OL2 (Overload): The motor or drive is being pushed beyond its current rating. Check for mechanical jams or reduce the load.OH (Overheat): Ensure the cooling fan is running and that there is sufficient airflow around the heat sink. Safety Precautions

The digital keypad serves as the primary interface for programming. The manual details the "Flow chart of parameter setting," which allows engineers to navigate through function codes to adjust everything from acceleration times to custom V/F curves.

Ensure proper grounding to prevent electrical shock. Control Wiring

Follow this simple operational check before running your machine under full load. Scenario A: Control Speed and Run from the Built-In Keypad Set to 0 (Keypad control mode). Set P0.06 to 0 (Digital keypad frequency setting mode).

Check mechanical system for jams; upgrade to a larger VFD/motor combo. Overvoltage (DC Bus)

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.

If you have just acquired this drive—new or used—make downloading the official manual your first task. Keep a printed copy in the electrical panel, store a digital copy on your phone, and bookmark the fault code table.

Input the values exactly as printed on your motor's nameplate to ensure vector control accuracy. : Rated motor power (Set to 0.75 kW) P1.02 : Rated motor frequency (Default 50.00 Hz / 60.00 Hz) P1.03 : Rated motor speed (RPM)
