CIMR-J7AA20P4 is a compact economical inverter of Yaskawa J7 series, designed for small-power ordinary speed regulation applications. It features small size, simple wiring and stable running performance, commonly used for small automation equipment, fans, pumps and mini conveyor maintenance replacement.

CIMR is Yaskawa standard inverter prefix; J7 stands for economical compact J7 series; AA is standard general specification; 2 means single/three-phase AC200V voltage grade; 0P4 refers to 0.4kW rated matching motor.

Matched rated motor power is 0.4kW with rated output current 2.4A. Input is single-phase AC200~230V, 50/60Hz; output voltage ranges from 0 to 230V, maximum output frequency up to 400Hz. It adopts basic V/F control mode, with simple terminal multi-speed control function. Built-in braking transistor allows external braking resistor connection for short stop demand. Complete protection includes overcurrent, overvoltage, undervoltage, overheat, overload and short-circuit protection.

Equipped with basic MEMOBUS Modbus-RTU communication function; supports analog voltage/current command input and multi-step fixed speed via external terminal switching. Simple acceleration and deceleration time setting fits ordinary light-load start-stop conditions.

Protection grade IP20 for cabinet indoor installation, natural air cooling without built-in fan. Operating ambient temperature ranges from 0℃ to 50℃, relative humidity 20%~80% without condensation, applicable installation altitude below 1000 meters.

Mainly used for small fans, water pumps, miniature conveying machinery, packaging auxiliary equipment and small processing automation speed control.
