CIMR-AU5A0099FAA

Designed for high-performance demands, the Yaskawa CIMR-AU5A0099FAA is a vector control AC drive capable of handling three-phase input at 600 volts. It features a flexible rated current specification, allowing for 99A under normal duty conditions and 77A during heavy duty operation. The impressive output frequency range from 0.01 Hz to 400 Hz enables adaptability for varying speed requirements across different motor types.

Control methodologies incorporated include voltage/frequency control, as well as open and closed-loop vector control, which together ensure precise motor management. To support heavy-duty applications, the drive provides a motor overload capacity of 150% for a duration of 60 seconds. This functionality enhances its utility in demanding settings.

A built-in braking transistor allows for effective energy dissipation during deceleration, contributing to overall system efficiency. In terms of protections, this model includes safeguards against situations like overvoltage, undervoltage, overcurrent, overload, and overheat, ensuring durability and reliability.

Its enclosure rating is IP00 for open-type configurations, with an optional IP20/NEMA 1 for increased environmental resilience. The ambient operating temperature can range from -10°C to 50°C, depending on the enclosure type. The forced air cooling method employed permits optimal operational performance even within this temperature span.

The drive operates with a default carrier frequency of 2 kHz, influencing the current derating accordingly. Power loss is recorded at approximately 1664.9W for normal duty and 1619W for heavy duty. Accuracy in speed control is notable, achieving ±0.2% in open loop and ±0.02% in closed loop configurations. In terms of installation, the drive can function effectively at altitudes of up to 1000 meters without derating and can be used at elevations of up to 3000 meters with necessary derating, thus extending its application range in various environments.
