The Yaskawa CIMR-J7AM43P7 functions as a 480V AC three-phase variable frequency drive. This unit can effectively handle a maximum motor output of 5 HP, making it suitable for controlling 4-pole motors under various operational conditions. The drive capacity stands at 7 kVA, ensuring robust performance in demanding environments.

It is designed with a rated output current of 8.6 A and requires a rated input current of 12.0 A for proper operation. The output voltage ranges from 380 to 460 V, adjusted proportionately to the input voltage. Designed to accommodate both 50 Hz and 60 Hz systems, it assures reliable functionality across diverse voltage and frequency specifications.

The device tolerates voltage fluctuations between -15% to +10% and frequency changes within ±5%, allowing it to maintain efficiency even under variable conditions. Its control method employs Sine Wave PWM technology, establishing a V/f pattern for frequency management. It offers a frequency range that spans from 0.1 Hz to 400 Hz.

In terms of overload capacity, the drive can handle 150% of its rated current for up to one minute without compromising performance. Additionally, it provides a continuous braking torque of 20% regenerative torque, which aids in maintaining energy efficiency. The protection rating for the enclosure is IP20, confirming its suitability for protected chasses against dust and minor object intrusion.
