is a compact, high-performance open-loop vector control inverter (Variable Frequency Drive) designed for small power applications, typically 0.75kW (1HP), 220V single-phase input/three-phase output [1, 2]. invt che100-0r7g-s2 manual
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
