The OMRON/Yaskawa CIMR-J7AZ21P5 is a compact V/f controlled inverter engineered for single-phase 200–240 V input applications requiring three-phase AC motor drive capability. Part of the VARISPEED mini J7 series, this unit delivers sine wave PWM control with output frequencies spanning 0.1 to 400 Hz and supports motor loads up to 1.5 kW. The inverter maintains ±0.01% frequency tolerance (digital reference, –10 to +50 °C) and ±0.5% tolerance with analog reference (25 ± 10 °C), making it suitable for precision industrial automation where stable speed control is essential.
