J7AA40P7

The Yaskawa J7AA40P7 functions as an AC inverter drive, classified as a variable frequency drive (VFD). Rated at 40 HP, or 30 kW, this device accommodates input voltages between 380 and 480 V AC in a three-phase arrangement. It produces an output frequency that ranges from 0.1 Hz to 400 Hz, providing flexibility for different motor control needs.

At 480 volts, the input current is measured at 59.0 A, while the output current is slightly lower at 57.0 A. With a robust overload capacity of 150% for a duration of one minute, this inverter can handle sudden surges effectively. The operational temperature range extends from -10°C to +50°C, making it suitable for varied environmental conditions. The drive employs a forced air cooling mechanism, utilizing an internal fan to maintain optimal temperatures during operation.

Key protection features incorporated into the design include mechanisms for overcurrent, overvoltage, undervoltage, overload, and short-circuit scenarios. These safety measures enhance the reliability and longevity of the device. Communication is seamless via the Modbus RTU protocol, making integration into broader control systems straightforward. The unit can also function in areas with ambient humidity levels reaching up to 95% RH.

Operating frequencies can be set to either 50 or 60 Hz, allowing adaptability in different applications. Utilizing vector control with PG feedback as well as V/f control, this drive ensures precise motor performance and control. The overall dimensions of the J7AA40P7 are 362 mm in width, 220 mm in height, and 300 mm in depth, allowing for efficient use of space in installations.
