The INVT CHE100 series is a highly efficient sensorless vector control drive designed for high-performance industrial applications. The CHE100-0R7G-S2 model specifically caters to low-power requirements, offering a 0.75kW output with a single-phase 220V input. Whether you are setting up a small conveyor, a fan, or a pump, understanding the technical specifications and programming logic of this inverter is essential for peak performance. Technical Specifications

Model Number: CHE100-0R7G-S2Rated Power: 0.75 kW (1.0 HP)Input Voltage: Single-phase 220V AC (±15%)Output Voltage: Three-phase 0–220V ACRated Current: 4.0AControl Mode: Sensorless Vector Control (SVC) or V/f ControlProtection Rating: IP20 Installation and Environment Guidelines

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

High Voltage Warning: After powering off the drive, wait at least 5 minutes for the DC bus capacitors to discharge before touching any terminals.No Capacitors: Never connect capacitors or surge absorbers to the output (U, V, W) terminals.Phase Insulation: Before connecting the motor, use a megohmmeter to ensure the motor phase-to-ground insulation is intact.

L, N: Connect your single-phase 220V AC power supply here.U, V, W: Connect these to your three-phase motor. (Note: Never connect input power to these terminals).(+) , (-): DC bus terminals for external braking units (if required).PE: Grounding terminal. Ensure a solid connection to prevent electromagnetic interference (EMI). Control Circuit Terminals

To ensure the longevity of your INVT drive, the installation environment must meet specific criteria:
