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. invt che100-0r7g-s2 manual
To ensure the longevity of your INVT drive, the installation environment must meet specific criteria: OC1 / OC2 / OC3 (Overcurrent): Check for
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 Safety Precautions High Voltage Warning: After powering off
P0.01 (Source of Run Command): 0 for Keypad, 1 for Terminal Control, 2 for Communication.P0.03 (Max Output Frequency): Usually set to 50.00Hz or 60.00Hz depending on your motor.P0.11 (Acceleration Time): Time in seconds to reach max frequency.P0.12 (Deceleration Time): Time in seconds to reach a full stop.P2.01 (Motor Rated Power): Set to 0.75kW.P2.02 (Motor Rated Voltage): Set to 220V.P2.05 (Motor Rated Current): Set according to your motor's nameplate (typically around 3.5A–4.0A). Troubleshooting Common Fault Codes
Mounting: Always install the unit vertically to allow for natural heat dissipation.Clearance: Maintain at least 100mm of space above and below the unit, and 50mm on the sides.Temperature: Operate between -10°C and +40°C. If the ambient temperature exceeds 40°C, derate the output current by 3% for every additional degree.Moisture and Dust: Avoid direct sunlight, high humidity (above 95% RH), and corrosive gases.
